Introduction
If you’re using Invisalign, you probably know that you should remove your aligners before eating—but what about drinks? Many people wonder, can i drink seltzer water with invisalign without affecting their treatment or damaging their trays. While sparkling water seems harmless, its carbonation and acidity may still impact your teeth and aligners. In this guide, we’ll explain what dentists recommend and how to safely enjoy sparkling water during your Invisalign treatment.
What Is Seltzer Water?
Before answering whether you can drink sparkling beverages during orthodontic treatment, it’s helpful to understand what seltzer water actually is and how it differs from other carbonated drinks. Many people assume all fizzy drinks are the same, but there are important differences that can affect both your Invisalign aligners and your dental health.
How Seltzer Water Is Different From Soda
Seltzer water is simply water that has been infused with carbon dioxide gas under pressure, creating the familiar bubbles and fizz. Unlike soda, it typically contains no added sugar, no artificial coloring, and no syrups.
Because of this, many people view sparkling water as a healthier alternative to traditional soft drinks. However, carbonation naturally forms a weak acid called carbonic acid, which gives the drink its slightly tangy taste. While the acidity level is much lower than sugary sodas, it can still affect tooth enamel if your teeth are exposed for long periods—especially when wearing clear aligners like Invisalign.
Another important difference is that soda often contains high levels of sugar or artificial sweeteners, which can increase the risk of tooth decay and cause staining in Invisalign trays. In contrast, plain carbonated water is generally considered much less harmful to teeth, although dentists still recommend caution when drinking it with aligners in place.
Popular Types of Sparkling Water
Not all sparkling waters are exactly the same. Several varieties exist, and their ingredients can slightly change how they interact with Invisalign aligners and your teeth.
The most common types include:
Seltzer Water
Plain carbonated water with no added minerals or sweeteners. This is the simplest form of sparkling water and typically the safest option for dental health.
Sparkling Mineral Water
Naturally carbonated water that comes from mineral springs. Brands like Perrier and San Pellegrino fall into this category and contain minerals such as calcium, magnesium, and sodium.
Club Soda
Carbonated water that has added minerals like sodium bicarbonate or potassium sulfate to enhance flavor. These additives don’t usually harm teeth, but they may slightly alter the drink’s acidity.
Flavored Sparkling Water
Products like LaCroix, Bubly, and Spindrift often contain natural flavors, fruit essences, or small amounts of citric acid. While still marketed as healthy drinks, flavored varieties may be more acidic than plain seltzer water, which is something to consider when wearing Invisalign trays.
Understanding these differences helps explain why orthodontists often recommend removing Invisalign aligners before drinking anything other than plain water. Even drinks that appear harmless, like carbonated water, may have small effects on enamel or become trapped between the teeth and the aligners.
Can You Drink Seltzer Water With Invisalign?
Many Invisalign users ask whether it’s safe to enjoy sparkling drinks while wearing their aligners. Since aligners must stay in your mouth for 20–22 hours per day, it’s natural to wonder if quick drinks like seltzer water are harmless enough to consume without removing them. The answer is a bit more nuanced than a simple yes or no.
The Short Answer
Technically, drinking plain seltzer water while wearing Invisalign aligners is less risky than drinking sugary beverages like soda or juice. Because it usually contains no sugar or coloring, it doesn’t create the same level of risk for staining or tooth decay.
However, most orthodontists still recommend removing your aligners before drinking anything except plain water. Even though carbonated water is relatively mild compared to other beverages, the bubbles create carbonic acid, which can slightly lower the pH level in your mouth. If this acidic liquid becomes trapped between your teeth and your clear aligners, it may expose enamel to acid for longer than normal.
For that reason, the safest approach during Invisalign treatment is to remove your aligners before drinking sparkling beverages, then rinse or brush your teeth before putting the trays back in.
Why Orthodontists Recommend Removing Aligners
There are several reasons dental professionals advise removing Invisalign trays before drinking sparkling water or other beverages.
First, clear aligners fit tightly against your teeth. If you drink carbonated beverages while wearing them, the liquid can become trapped between the tray and your teeth. This creates a small enclosed environment where acids or bacteria may sit against the enamel longer than they normally would.
Second, repeated exposure to acidic drinks—even mild ones like seltzer water—can gradually weaken tooth enamel. While the effect is typically minimal with occasional exposure, drinking sparkling beverages frequently while wearing Invisalign aligners may increase the risk of enamel erosion over time.
Another concern is the condition of the aligners themselves. Although carbonated water is clear, flavored varieties may contain acids or natural extracts that can leave residue inside the trays. Over time, this may lead to cloudy aligners, odors, or plaque buildup.
Finally, orthodontists want to ensure that Invisalign treatment progresses smoothly. Removing your trays before drinking helps protect both your teeth and the aligners, while also encouraging better oral hygiene habits throughout the treatment process.
What Happens If You Drink Sparkling Water With Invisalign?
At first glance, drinking sparkling water while wearing Invisalign aligners may seem harmless. After all, it usually contains no sugar and no artificial coloring. However, even seemingly mild beverages can have subtle effects on both your teeth and your aligners when they are consumed while the trays are in place. Understanding these effects helps explain why orthodontists often recommend removing clear aligners before drinking anything other than plain water.
Carbonic Acid and Tooth Enamel
The bubbles in carbonated water come from dissolved carbon dioxide. When carbon dioxide mixes with water, it forms a weak acid known as carbonic acid. This is what gives sparkling water its slightly tangy taste.
While the acidity level in seltzer water is much lower than in soda or sports drinks, it can still temporarily lower the pH level in your mouth. When this happens, tooth enamel becomes slightly more vulnerable to demineralization, a process where minerals like calcium are gradually lost from the enamel surface.
Normally, saliva helps neutralize acids and restore balance in the mouth. However, when you are wearing Invisalign aligners, the trays cover your teeth and reduce the natural flow of saliva around them. If sparkling water gets trapped between the aligners and your teeth, the enamel may remain exposed to mild acidity for longer than usual. Over time, repeated exposure could increase the risk of enamel erosion, especially if sparkling drinks are consumed frequently throughout the day.
Risks to Invisalign Aligners
Drinking carbonated beverages while wearing Invisalign trays can also affect the aligners themselves. Even though plain sparkling water is clear, liquids can still become trapped inside the trays, creating an environment where bacteria can accumulate.
One common issue is plaque buildup. When liquid sits between the teeth and the aligners, it may mix with natural bacteria in the mouth. Because clear aligners fit tightly around the teeth, this trapped moisture can encourage bacterial growth and lead to unpleasant odors inside the trays.
Another potential concern is aligner cloudiness. Over time, exposure to acidic or flavored drinks may cause Invisalign aligners to appear slightly dull or cloudy. While this doesn’t necessarily damage the aligners structurally, it can make them look less transparent, which defeats part of the cosmetic advantage of using clear aligners.
There is also a hygiene factor to consider. If you frequently drink sparkling water while wearing Invisalign, the trays may need more frequent cleaning to prevent buildup and maintain freshness. Without proper cleaning habits, residue trapped inside the aligners could contribute to bad breath or minor staining.
For these reasons, dentists and orthodontists generally recommend removing Invisalign aligners before drinking any beverages besides plain water. Doing so helps protect your enamel, maintain the clarity of your aligners, and keep your Invisalign treatment on track.

Is Flavored Seltzer Water Worse?
Many people choose flavored seltzer water because it offers the refreshing fizz of sparkling water with a hint of taste—without the sugar found in soda. However, when it comes to wearing Invisalign aligners, flavored versions of sparkling drinks can introduce additional concerns compared to plain seltzer water.
Although these beverages are often marketed as healthy alternatives, their ingredients may still affect both your teeth and your clear aligners if consumed while the trays are in place.
Artificial Flavors and Acidity
One key difference between plain carbonated water and flavored sparkling water is the presence of added flavor compounds. These flavors often come from fruit extracts or natural flavorings, which may increase the drink’s acidity.
Many flavored sparkling waters contain ingredients like citric acid or fruit-derived acids that enhance the taste. Citrus-flavored drinks such as lemon, lime, or grapefruit varieties tend to be more acidic than plain seltzer water. This added acidity can lower the pH level in your mouth more significantly.
When wearing Invisalign aligners, this becomes more important because the trays cover your teeth and can trap liquids against the enamel. If acidic beverages remain inside the aligners for extended periods, they may increase the risk of enamel erosion or tooth sensitivity over time.
Even though these drinks do not contain sugar, the acidic environment they create can still impact dental health during Invisalign treatment if consumed frequently without removing the aligners.
Hidden Ingredients to Watch For
Another factor to consider is that some flavored seltzer water products contain additional ingredients that are not immediately obvious. While many brands promote themselves as simple and natural, certain additives may still influence oral health or affect the appearance of Invisalign trays.
Common ingredients to watch for include:
Citric acid
Often added to enhance the tartness of fruit flavors. This ingredient can increase acidity and contribute to gradual enamel wear.
Natural or artificial flavorings
These compounds give drinks their fruity taste. While generally safe, they may leave residue inside clear aligners if beverages are consumed while the trays are worn.
Sweeteners or fruit concentrates
Some flavored sparkling waters contain small amounts of fruit juice or sweeteners, which may introduce sugars or carbohydrates that feed oral bacteria.
When these ingredients are trapped between your teeth and Invisalign aligners, they may increase the risk of plaque formation, unpleasant odors, or cloudy trays.
For this reason, orthodontists usually advise removing Invisalign trays before drinking flavored sparkling water, even if the drink appears sugar-free. Doing so helps protect your enamel, maintain the clarity of your aligners, and support healthy oral hygiene throughout your Invisalign treatment.
How To Drink Sparkling Water Safely During Invisalign
Enjoying sparkling water during Invisalign treatment doesn’t necessarily mean you have to give it up completely. The key is following a few simple habits that protect both your teeth and your Invisalign aligners. Orthodontists generally recommend being mindful of how and when you drink carbonated beverages so that they don’t interfere with your progress or oral health.
By adopting the right routine, you can still enjoy an occasional glass of seltzer water while keeping your clear aligners clean and your treatment on track.
Remove Your Aligners First
The safest approach when drinking sparkling water is to remove your Invisalign trays beforehand. Although carbonated water is less harmful than sugary beverages, it still contains mild acidity that can linger between the teeth and the aligners if consumed while the trays are in place.
Because Invisalign aligners fit snugly over your teeth, any liquid that enters the trays may remain trapped against the enamel. Removing the aligners before drinking prevents this from happening and allows saliva to naturally neutralize the acidity.
Taking out your trays before drinking also protects them from possible residue buildup or cloudiness. This simple habit helps maintain the transparency of clear aligners and keeps them looking discreet throughout your treatment.
Rinse Your Mouth After Drinking
After finishing your drink, it’s a good idea to rinse your mouth with plain water. This quick step helps wash away any remaining acids from sparkling water and restores a more balanced environment in your mouth.
Rinsing is particularly helpful if the drink was a flavored seltzer water, which may contain ingredients like citric acid or fruit flavorings. By rinsing your mouth, you reduce the chance that these substances will linger on the teeth and potentially affect enamel.
In addition, rinsing can help remove small particles or bacteria that might otherwise become trapped once you put your Invisalign aligners back in place.
Brush Before Putting Aligners Back
For the best oral hygiene during Invisalign treatment, orthodontists often recommend brushing your teeth before reinserting your Invisalign trays, especially after drinking beverages other than plain water.
Brushing removes bacteria, plaque, and any leftover acidity that could remain on your teeth. If aligners are placed back over unclean teeth, those substances may stay trapped inside the trays for hours, increasing the risk of plaque buildup, bad breath, or enamel problems.
Even when brushing immediately isn’t possible, rinsing your mouth and your clear aligners with water can still help minimize residue until you can brush properly.
Drinks That Are Safe With Invisalign
One of the most common questions people ask during Invisalign treatment is which beverages they can safely drink while wearing their aligners. Because Invisalign aligners must stay in place for about 20–22 hours a day, knowing which drinks are safe can help you avoid damaging your trays or affecting your dental health.
In general, orthodontists recommend that plain water is the only drink that can be consumed without removing clear aligners. Other beverages may contain sugars, acids, or pigments that could harm your teeth or cause staining inside the aligners.
Understanding which drinks are safe—and which require removing your Invisalign trays—can help keep your treatment on schedule and maintain good oral hygiene.
Drinks You Can Have Without Removing Aligners
The safest beverage to drink while wearing Invisalign aligners is plain water. Water does not contain sugar, acids, or coloring agents that might damage tooth enamel or stain clear aligners.
Drinking water with your aligners in place also helps maintain hydration and can even support oral health by rinsing away food particles and bacteria. Because Invisalign trays fit snugly against the teeth, choosing neutral drinks like water ensures that nothing harmful becomes trapped between the teeth and the aligners.
Some safe options include:
Plain still water
This is the best and safest choice during Invisalign treatment. It does not affect enamel or the clarity of your aligners.
Cold water
Cold or chilled water is completely safe for Invisalign aligners and can also help keep your mouth refreshed throughout the day.
Room temperature water
Many orthodontists recommend avoiding very hot drinks while wearing clear aligners, so room temperature water is another ideal option.
In short, if your aligners are in your mouth, plain water should be your go-to drink.
Drinks That Require Removing Aligners
Most other beverages should be consumed only after removing your Invisalign trays. This includes drinks that contain sugar, acidity, caffeine, alcohol, or strong coloring agents.
Some common examples include:
Coffee and tea
Hot beverages can warp clear aligners, while darker drinks may stain them over time.
Soda and sugary drinks
These beverages contain sugar and acids that can increase the risk of tooth decay when trapped under Invisalign aligners.
Sparkling water and flavored seltzer
Even though sparkling water is often sugar-free, its carbonation creates mild acidity that can affect enamel if trapped inside the aligners.
Fruit juice and sports drinks
These drinks often contain high levels of sugar and acids that may contribute to plaque buildup and enamel erosion.
Alcoholic beverages
Drinks such as wine, beer, or cocktails may stain Invisalign trays and often contain sugars or acids that can harm dental health.
By removing your Invisalign aligners before drinking these beverages, you reduce the risk of staining, bacterial buildup, and enamel damage. After drinking, it’s best to rinse your mouth or brush your teeth before placing your clear aligners back in.
Following these guidelines helps keep your Invisalign treatment progressing smoothly while protecting both your teeth and your aligners.
Drinks You Should Avoid With Invisalign
While Invisalign aligners are designed to be convenient and discreet, they still require certain lifestyle adjustments—especially when it comes to beverages. Some drinks can negatively affect both your teeth and your clear aligners, particularly if consumed while the trays are still in place. Sugary, acidic, or strongly colored drinks may increase the risk of staining, bacterial growth, or damage to your enamel during Invisalign treatment.
Understanding which beverages to avoid can help protect your oral health and keep your aligners clean and transparent throughout the treatment process.
One of the most important drinks to avoid with Invisalign aligners is soda. Soft drinks typically contain high levels of sugar and acid, which can significantly increase the risk of tooth decay if the liquid becomes trapped between the teeth and the aligners. Because clear aligners cover the teeth closely, sugary liquids can remain in contact with enamel for extended periods, creating an environment where harmful bacteria thrive.
Similarly, sports drinks and energy drinks should be avoided while wearing Invisalign trays. Although they are often marketed as hydration beverages, many of these drinks contain large amounts of sugar and citric acid. These ingredients can contribute to enamel erosion and may lead to plaque buildup when consumed frequently during Invisalign treatment.
Another category to be cautious about is fruit juice. Even natural juices like orange, apple, or grape juice contain natural sugars and acids. While these drinks may seem healthy, their acidity can weaken tooth enamel, especially if consumed repeatedly while wearing Invisalign aligners. Additionally, darker juices may stain clear aligners, making them appear cloudy or discolored.
Coffee and tea are also common beverages that should not be consumed with Invisalign trays in place. Both drinks can stain the aligners and may cause them to lose their transparent appearance. Hot beverages present an additional concern because excessive heat can potentially warp clear aligners, affecting how they fit and function.
Alcoholic beverages are another drink category that should be handled carefully during Invisalign treatment. Drinks like red wine, beer, and cocktails often contain pigments, sugars, or acids that can stain Invisalign aligners or contribute to enamel damage. Dark-colored alcohol, in particular, can quickly discolor the trays if they are worn while drinking.
Finally, while sparkling water and flavored seltzer water may seem harmless compared to soda, they still contain carbonation and sometimes added acids. If consumed frequently while wearing Invisalign aligners, these drinks may expose your teeth to mild acidity for extended periods.
For the best results, orthodontists recommend removing your Invisalign trays before drinking anything other than plain water. This simple habit helps protect your enamel, prevents staining, and keeps your clear aligners looking clean and transparent throughout your treatment journey.
Invisalign Care Tips From Orthodontists
Proper care is essential to get the best results from Invisalign treatment. Since Invisalign aligners are designed to be worn most of the day, maintaining good hygiene and following orthodontists’ recommendations can help ensure that your teeth move as planned and that your aligners stay clean and discreet.
Orthodontists typically advise wearing clear aligners for 20–22 hours per day. This consistent wear time allows the aligners to gradually shift your teeth into their correct positions. Removing them too frequently or leaving them out for extended periods may slow down your progress and extend the total duration of your Invisalign treatment.
Another important habit is cleaning your Invisalign trays regularly. Because the aligners sit directly against your teeth, they can collect saliva, bacteria, and plaque over time. Most orthodontists recommend gently brushing the aligners with a soft toothbrush and rinsing them with lukewarm water. Using hot water should be avoided, as excessive heat may warp clear aligners and affect their fit.
Maintaining strong oral hygiene is equally important. Before placing Invisalign aligners back into your mouth, it’s best to brush and floss your teeth thoroughly. Doing so removes food particles and bacteria that could otherwise become trapped between the teeth and the aligners. When debris remains under Invisalign trays, it may increase the risk of plaque buildup, bad breath, or tooth decay.
Orthodontists also recommend avoiding very hot beverages while wearing clear aligners. Heat can slightly distort the plastic material used in Invisalign trays, which may compromise how accurately the aligners guide tooth movement. If you plan to drink coffee, tea, or other warm beverages, it’s best to remove your aligners first.
Another helpful tip is to always store your Invisalign aligners in their protective case when they are not in your mouth. This prevents accidental damage, loss, or exposure to bacteria. Leaving the aligners on a table or wrapped in a napkin can make them easy to misplace.
Finally, keeping up with regular orthodontic checkups is essential during Invisalign treatment. Your orthodontist monitors your progress, ensures that your teeth are moving correctly, and provides the next set of aligners in your treatment series. These visits also allow professionals to check the condition of your clear aligners and give personalized advice for maintaining optimal oral health.
By following these simple care tips, you can keep your Invisalign aligners clean, protect your teeth, and help ensure that your treatment progresses smoothly from start to finish.
Final Verdict: Should You Drink Seltzer Water With Invisalign?
In short, plain seltzer water is less harmful than sugary or colored drinks, but orthodontists still recommend removing your aligners before drinking it. If you’re wondering can i drink seltzer water with invisalign, the safest answer is: only after taking your Invisalign aligners out. Carbonation creates mild acidity that may stay trapped between your teeth and clear aligners, which could affect enamel over time. To protect your teeth and keep your trays clear, drink sparkling water without your aligners, rinse your mouth afterward, and place your Invisalign trays back in once your teeth are clean.
