Can You Drink Coffee, Tea, or Turmeric While Wearing Invisalign?

Invisalign trays are engineered from patented thermoplastic polyurethane. When exposed to temperatures above 45°C (113°F)—typical for freshly brewed hot filter coffee or chai—the plastic softens and warps.

Even a microscopic millimeter of thermal distortion prevents the aligner from seating correctly on your teeth, disrupting the calculated force vectors and causing tracking errors.

Coffee, black tea, and especially turmeric (curcumin) contain intensely potent chromogens. When you drink with aligners in, the liquid seeps between the plastic tray and your enamel, creating a stagnant pool of pigmented fluid.

Not only does this stain the clear aligners bright yellow or brown within minutes, but the trapped tannins and sugars stay bathed against your enamel, sharply elevating your risk of tooth decay.

• Cool, Plain Water: The ONLY beverage you should drink freely while wearing your aligners.
• For Coffee, Tea, Juices, and Alcohol: Remove your aligners, enjoy your drink, rinse your mouth thoroughly with water (or brush), and pop the aligners back in.
• Cold Coffee or Iced Tea with a Straw: If you are on the go, drinking iced coffee with a straw positioned toward the back of your throat minimizes contact, but you must still rinse at the earliest opportunity.
