Invisalign is a popular orthodontic treatment, providing a non-invasive way to fix issues while being simple to follow. However, there are common concerns about how using Invisalign may affect you in the day-to-day, particularly with eating and drinking.
The Cosmetic Dental Gallery have worked with many clients over the years using Invisalign, and we’ve learned the Do’s and Don’ts of using these aligners, as well as maintenance advice.
Can You Eat with Invisalign?
It’s natural to wonder if you can eat while wearing aligners, especially if you’re not sure how Invisalign works. Unfortunately, it is not recommended to eat while using your Invisalign aligners. There are many reasons, but the core risks are:
- Your aligners cracking, warping, or staining
- The effectiveness of the aligners reduces due to damage
- Food particles getting trapped and causing plaque buildup
Invisalign aligners are not designed to withstand the pressure of chewing. While it may feel inconvenient to take them out any time you want to eat something, it’ll pay for itself in the long run when the treatment is completed smoothly.
Always be careful when taking Invisalign out as well. If you’re in a rush (such as to eat something) and drop the aligners, you could risk accidentally damaging them.
The Do’s and Don’ts of Eating with Invisalign
Understanding what is safe and unsafe to do while eating can help prevent damage to your aligners and maintain oral hygiene throughout treatment.
Do:
- Remove your aligners before every meal or snack, even for soft foods.
- Store aligners in a proper case to avoid contamination or loss while eating.
- Brush or rinse your teeth before putting aligners back in to prevent plaque buildup.
Don’t:
- Eat anything with aligners in, as chewing pressure can crack or deform the trays.
- Expose aligners to hot foods, which can warp the plastic.
- Leave aligners out for extended periods, as this reduces necessary wear time.
What Happens If You Eat With Invisalign In?
While Invisalign aligners are designed to fit snugly over your teeth, they are not designed to withstand the pressure of chewing. Eating with Invisalign in place can cause several problems that may affect both your treatment progress and your oral health.
When food is chewed, pressure is applied directly to the aligners. This can cause them to crack, bend, or lose their precise shape. Even minor distortions may affect how effectively the trays move your teeth.
Food particles can also become trapped between your teeth and the aligners. Because the trays create a sealed environment, bacteria, sugars, and acids remain in close contact with the tooth surface, increasing the risk of plaque buildup, bad breath, cavities, and gum irritation.
In addition, many foods can stain clear aligners, making them more visible and reducing one of Invisalign’s biggest advantages: its discreet appearance.
Can You Eat Soft Foods With Invisalign?
A common misconception is that soft foods are safe to eat while wearing Invisalign. Unfortunately, even foods that require minimal chewing should be avoided while your aligners are in place.
This includes foods and drinks such as:
- Yoghurt
- Bananas
- Mashed potatoes
- Smoothies
- Soup
- Ice cream
Although these foods are softer than crunchy or sticky alternatives, they can still leave residue on your aligners or trap sugars against your teeth. Smoothies, flavoured yoghurts, and mashed foods often contain natural or added sugars that may increase the risk of tooth decay if aligners are worn during consumption.
The safest approach is always to remove your aligners before eating any food, regardless of texture, and clean your teeth before reinserting them.
Can You Drink with Invisalign?
Hydration is important, especially when you’re on a journey to fixing dental issues. While wearing your Invisalign, you will have restrictions on what you can drink.
Water is the only safe drink to consume with aligners in. So you can stay hydrated, but if you’re somebody who prefers drinking acidic and sugary drinks, you’ll have to make some lifestyle adjustments.
Acidic drinks can cause enamel erosion if trapped under aligners. If you drink warm drinks (coffee, tea) you risk staining your aligners and teeth. Due to the temperature of these beverages, they can also warp the aligners, meaning they won’t fit correctly.
In short, stick to water when you’re wearing Invisalign, and you’ll avoid any issues.
The Do’s and Don’ts of Drinking with Invisalign
Drinking habits often need small adjustments during Invisalign treatment, especially because liquids can seep between the aligner and teeth.
Do:
- Drink cool or room-temperature water freely while aligners are in.
- Remove aligners before drinking anything flavoured, sugary, or acidic.
- Rinse both teeth and aligners if you accidentally sip something other than water.
Don’t:
- Drink hot beverages like coffee or tea with aligners in, as heat can distort them.
- Consume alcohol, energy drinks, or soft drinks while wearing aligners due to staining and sugar exposure.
- Sip beverages slowly over long periods, which keeps sugar or acids trapped under aligners.
Safe vs Unsafe Foods and Drinks With Invisalign
Understanding which foods and drinks are safe can make daily life with Invisalign much easier.
| Category | Safer Choices (Aligners Removed) | Avoid With Aligners In |
| Drinks | Water, milk, herbal tea | Coffee, tea, juice, sports drinks, fizzy drinks, wine |
| Soft Foods | Yoghurt, bananas, mashed potatoes, pasta | Any food consumed while aligners remain in |
| Snacks | Cheese, fruit, crackers | Sticky sweets, chewing gum |
| Meals | Rice, vegetables, fish, chicken | Any meal eaten while wearing aligners |
| Desserts | Soft cakes, pudding | Sticky or chewy sweets |
Remember, water is the only drink considered safe while aligners are being worn. Everything else should be consumed after removing your trays.
Best Practices for Eating and Drinking with Invisalign
As mentioned previously, you shouldn’t eat anything while wearing Invisalign aligners, and stick to only water for drinks. It will feel like a lifestyle adjustment at first, but here’s how to make the most out of your day while wearing Invisalign.
Always Remove Aligners Before Eating
You should always remove Invisalign before eating any food. They should also be stored properly to avoid misplacement or contamination. Here is a step-by-step process for removing aligners safely:
- Wash your hands: Wash your hands using soap and warm water for at least 20 seconds. After washing, dry your hands with a clean towel.
- Start from the back teeth: Using your fingertips, gently hook the edge of the aligner near your back molar on one side. Pull the aligner down and away from the teeth. Repeat on the other side.
- Work toward the front teeth: Once you’ve loosened the back section, begin moving forward. Be gentle but firm, but make sure you’re not cracking or bending the aligner.
- Use an aligner removal tool: If you’re struggling to remove your aligners by hand, you can try an aligner removal tool.
- Rinse the aligners: After you’ve removed your aligners, rinse them under lukewarm water. Avoid hot water, as this can cause the aligners to warp.
Invisalign Eating Schedule: How to Wear Aligners for 22 Hours a Day
You’re recommended to wear your aligners for 20-22 hours a day. This can make structuring eating habits difficult, especially if you’re a snacker.
Try to eat meals at the same time and place everyday. This will make it easier for you to follow a routine of taking out the aligners, rinsing them, and then eating your meal before putting them back in. It can quickly become tempting to avoid wearing Invisalign for the day if you’re out of the house when hunger strikes.
Many Invisalign patients find it helpful to combine eating, drinking, and oral hygiene into structured meal windows. Doing so makes it easier to achieve the recommended 22 hours of wear per day.
A typical routine might look like:
- Breakfast: Remove aligners, eat and drink, brush teeth, reinsert aligners.
- Lunch: Remove aligners for your meal, rinse or brush afterwards, then reinsert.
- Dinner: Remove aligners for your final main meal, clean your teeth thoroughly, then wear aligners for the rest of the evening.
- Snacks: Where possible, combine snacks with mealtimes to reduce the number of times aligners are removed.
For example, if aligners are removed for 30 minutes at breakfast, 30 minutes at lunch, and one hour at dinner, total wear time still exceeds 22 hours. This keeps treatment on track while allowing enough time for meals and cleaning.
Rinsing and Brushing After Eating
Rinsing and brushing after eating is recommended when you’re using Invisalign. By ensuring your teeth are clean before reinserting the aligners, you’ll make sure that there’s no plaque getting stuck and then building up. It’ll also prevent any staining from food/drink passing from your teeth to the aligners.
Keeping on top of oral hygiene is crucial for everybody, but especially for somebody using Invisalign. Here’s some products to add to your oral hygiene routine:
- Floss or interdental brushes: Food particles regularly become trapped in-between teeth, so making sure you’re hitting those areas is crucial. Floss or interdental brushes are a simple way to do so, and will keep your mouth smelling and feeling clean!
- Antimicrobial mouthwash: A non-alcoholic mouthwash can kill bacteria, freshen breath, and reduce plaque buildup.
- Aligner cleaning solutions: To keep your aligners clean, soak them in a mild, non-abrasive cleaning solution.

What Is the 30-Minute Rule With Invisalign?
The 30-minute rule refers to waiting approximately 30 minutes after consuming acidic foods or drinks before brushing your teeth.
Acidic beverages such as coffee, tea with lemon, fruit juice, sports drinks, fizzy drinks, and wine can temporarily soften tooth enamel. Brushing immediately afterwards may contribute to enamel wear over time.
A better approach is to:
- Remove your aligners before eating or drinking.
- Rinse your mouth thoroughly with water afterwards.
- Wait around 30 minutes if you’ve consumed acidic foods or drinks.
- Brush and floss your teeth.
- Reinsert your aligners.
Following this routine helps protect your enamel while maintaining good oral hygiene throughout Invisalign treatment.
How to Clean Invisalign After Eating and Drinking
For optimal performance of your Invisalign, you should have a daily cleaning routine. Here’s a step by step guide on cleaning your aligners after meals:
- Gently take out your aligners from the back of your mouth first, moving towards the front.
- Avoid using excessive force to prevent damaging the aligners.
- Rinse the aligners under lukewarm water to remove saliva and food particles.
- Avoid using hot water, as it can warp the aligners’ shape.
- Use a soft-bristled toothbrush and mild soap to gently scrub both the inside and outside of the aligners.
- Avoid using toothpaste, as some formulations contain abrasives that may scratch the aligners and cause them to become cloudy.
- Place aligners in a designated cleaning solution, such as Invisalign cleaning crystals or a mixture of mild soap and water, for 15-20 minutes.
- Once the aligners have been cleaned and soaked, rinse them thoroughly with water to remove any cleaning solution residue.
- Dry them with a clean, lint-free cloth before reinserting them into your mouth.
To keep your aligners clean and free of bacteria, consider the following cleaning options:
Invisalign Cleaning Crystals: Specifically designed for Invisalign aligners, these crystals help remove plaque and odor-causing bacteria without damaging the plastic.
Simply dissolve the crystals in water and soak your aligners for the recommended duration.
Mild Liquid Soap: A gentle, antibacterial soap diluted in water can effectively clean aligners without leaving residue or causing scratches.
Choose a clear, fragrance-free soap to avoid unwanted flavors or odors.
Baking Soda Solution: A natural, gentle cleaning option that helps remove stains and odors without being too abrasive.
In addition to cleaning the aligners themselves, it is equally important to clean your teeth before putting the trays back in. Food debris and bacteria trapped beneath aligners can increase the risk of plaque buildup, tooth decay, and gum irritation.
If you are away from home and cannot brush immediately, rinse your mouth thoroughly with water and clean your teeth properly as soon as possible. Carrying a travel toothbrush, toothpaste, and aligner case can make this much easier when commuting around London or eating out.
You should also clean your aligners daily even if you have not eaten recently. A consistent cleaning routine helps prevent odours, staining, and bacterial buildup throughout treatment.
What Should You Do If You Accidentally Eat or Drink With Invisalign In?
Accidentally taking a sip of coffee or forgetting to remove your aligners before a snack happens to many Invisalign patients. In most cases, a one-off mistake will not ruin your treatment, but it should be addressed promptly.
If this happens:
- Remove the aligners as soon as possible.
- Rinse both your mouth and aligners with lukewarm water.
- Brush and floss your teeth when available.
- Inspect the aligners for any signs of staining, cracking, or warping.
- Reinsert them once everything is clean.
If you notice that the aligners no longer fit properly or have become visibly damaged, contact your Invisalign provider for advice before moving to your next set of trays.
Common Invisalign Mistakes That Can Delay Treatment
Even small habits can affect how efficiently Invisalign works. Avoiding these common mistakes can help keep your treatment on schedule.
Not Wearing Aligners for Long Enough
Invisalign aligners should typically be worn for 20-22 hours per day. Frequently leaving them out for extended periods can slow tooth movement and extend treatment times.
Drinking Coffee, Tea, or Sugary Drinks With Aligners In
These drinks can stain aligners, increase cavity risk, and potentially damage the trays.
Skipping Brushing After Meals
Food particles trapped beneath aligners create an ideal environment for bacteria, plaque buildup, and bad breath.
Using Hot Water to Clean Aligners
Hot water can warp the plastic and affect the fit of the aligners. Always use cool or lukewarm water.
Losing or Damaging Aligners
Leaving trays loose on tables, wrapped in napkins, or stored improperly can result in accidental damage or loss. Always use a protective aligner case.
Ignoring Fit Issues
If an aligner suddenly feels loose, tight in unusual areas, or visibly warped, contact your Invisalign provider rather than continuing without guidance.
Balancing Invisalign With Daily Eating and Drinking
Invisalign will encourage a lifestyle shift and some extra steps before and after meals, but the long-term benefits outweigh any short-term compromises.
Take good care of your aligners, and they’ll take care of your smile. If you have any concerns with Invisalign, you can contact The Cosmetic Dental Gallery today for a consultation with a trusted Battersea or Greenwich dentist!
