Key Takeaways

  • Water is the only drink you should have while wearing clear aligners.
  • Staying hydrated helps reduce dry mouth and supports healthier teeth and gums.
  • Drink water regularly instead of waiting until you feel thirsty.
  • Avoid sugary, acidic, or hot beverages while your aligners are in.
  • Consistent hydration improves comfort, but wearing your aligners as instructed is what keeps treatment on track.


Staying hydrated while wearing clear aligners is easy because you can drink plain water with the aligners in your mouth. That said, to drink anything other than plain water at room temperature, you need to remove your aligners first.

Overall, if you are sticking with the regular recommended water intake for hydration, aligners don’t interfere with that. However, if you are more inclined to have different sources for hydration, then you plan your aligner wear schedule around it. Here’s more.

Clear Aligners and Hydration: Balancing the Two

In fact, drinking enough water is one of the best ways you can maintain hydration during treatment. Wearing clear aligners doesn’t mean you have to rethink staying hydrated. Water is safe to drink while wearing your aligners, and it helps rinse away food particles and bacteria that can build up between your teeth and trays.

It also keeps your mouth from feeling dry, which is especially helpful if you're prone to dry mouth while wearing aligners. Oral health and hydration are deeply connected, and clear aligners don’t interfere with them.

Drinking Water with Clear Aligners

The key is to make water your go-to drink. Sugary beverages, coffee, tea, and sports drinks can get trapped beneath your aligners, increasing the risk of stains, bad breath, and tooth decay. If you want to enjoy anything besides water, simply remove your aligners first, then brush your teeth or rinse your mouth before putting them back in.

Drink Before Reinserting Your Aligners

After meals or snacks, have a glass of water before putting your aligners back in. It helps you stay hydrated and rinses away leftover food particles.

Set Hydration Reminders

If you often forget to drink water, use your phone or smartwatch to remind you to take a few sips every hour.

Eat Water-Rich Foods During Meals

Foods like watermelon, cucumbers, oranges, strawberries, and lettuce contribute to your daily hydration while also providing important nutrients.

Limit Dehydrating Beverages

Too much coffee, alcohol, or caffeinated soft drinks can contribute to dehydration. If you have them, drink extra water afterward and only consume them with your aligners removed.

Stay Ahead of Dry Mouth

If your mouth feels dry while wearing aligners, increase your water intake throughout the day instead of drinking large amounts all at once. Small, frequent sips are often more effective.

Can Clear Aligners Cause Dry Mouth?

Now, let’s address this. Yes, clear aligners can cause dry mouth, but it is usually just for the first few days. The plastic trays act as a physical barrier over your teeth, which can disrupt the normal flow and distribution of saliva. Wearing them can also encourage unconscious mouth breathing and change your drinking habits, leading to a parched feeling. But a simple hydration routine,

Just remove them, follow any hydration program you like, rinse and brush your teeth, and wear aligners back. Still, sticking to plain water might be easier. With that, it’s a wrap; happy hydration.
