What can you eat and drink with clear aligners?

Food with the aligners out: the AAO’s answer and Align’s

Asked what cannot be eaten with aligners, the FAQ of the American Association of Orthodontists (AAO) answers with a condition: “Nothing is off-limits. Just be conscious of the need to take out aligners to eat, and to clean your teeth before putting your aligners back in.”

Align Technology, which makes Invisalign aligners, adds snacks in an October 2026 article: “Simply take your aligners out before meals and snacks, and put them back in after you’ve finished eating and cleaned your teeth.” On Align’s wording, a snack follows the same steps as a meal.

Those lines describe how aligners come out and go back, and they are not a menu. A question about a particular food for your own teeth goes to your orthodontist. Meals sit beside wear, cleaning and the case in the daily routine described on the clear aligners page.

Drinks with the aligners in: water is the one exception

Water is the only exception the AAO and Align make for drinking with aligners in. The AAO’s FAQ says “Tap water is the only beverage that is safe to drink when your aligners are in,” and Align’s October 2026 article says “The one rule to keep in mind: only drink plain water while wearing your aligners.”

Anything else means taking the aligners out first: the AAO’s FAQ says “If you eat or drink anything besides tap water, remove your aligners first,” which sets no small amount aside. Both publishers draw the line at water, and a particular drink you are unsure about is a question for your orthodontist.

What other drinks can do: stains, cavities and warped plastic

Liquid held against the teeth is the reason the AAO gives for keeping other drinks out while aligners are in. The AAO’s June 2024 article on clear aligner therapy says, “Avoid any drink that is not water while your aligners are in. Liquid trapped against the teeth may stain the aligner and teeth, and can cause cavities to develop.”

A January 2019 AAO article comparing braces and clear aligners names some of those drinks: “It is critical to avoid drinking soft drinks, flavored waters or sports drinks of any kind with aligners in. Liquids seep into aligners and if they contain acid, sugar, or both, it can rapidly lead to staining of the teeth and extensive decay.”

Align’s October 2026 article adds heat: “Hot beverages like coffee or tea can warp the plastic, and sugary or acidic drinks can get trapped against your teeth, increasing the risk of cavities.” By the AAO’s and Align’s lines, any of these drinks means taking the aligners out first.

The AAO’s June 2024 article also names gum disease beside cavities among the risks of what aligners trap against the teeth, and gums that swell during treatment are the subject of the page on swollen gums with braces.

Brushing between the meal and the aligners

Brushing comes between eating and putting the aligners back, in the AAO’s instructions. The AAO’s FAQ says “After you are done drinking or eating, brush your teeth before putting your aligners back in,” and the AAO’s December 2025 hygiene article says “Ideally, you should be brushing after every meal with toothpaste.”

Cleaning the aligners themselves is a separate job, set out in how to clean clear aligners.

The case at mealtimes, and a lost aligner

The case is where aligners go when they come out for a meal, in the AAO’s and Align’s instructions alike. The AAO’s June 2024 article says “When you remove your aligners, make it a habit to slip them into their case. Do not place aligners in napkins, a pocket, or a purse; keep them away from pets.” Align’s April 2026 article says “Always use the case to prevent loss or damage when not in use.”

If an aligner does go missing, that is a call to the office. If you call our regular phone number after hours, you will hear the phone number of the person on call. More day-to-day answers are in the practice’s list of questions.
