Living with aligners

Can I drink flavored water with Invisalign?

Invisalign instructions say only cool or tepid water should be drunk while trays are in; flavored or colored drinks should be avoided because they can stain or (if hot) warp aligners.

No—Invisalign patient instructions say you should only drink cool or tepid water while wearing active aligners, and recommend not drinking flavored or other beverages with trays in place. [1]

Quick takeaways

  • Official patient guidance: only cool or tepid water while wearing aligners.
  • Laboratory studies show clear-aligner materials can stain when exposed to colored beverages.
  • Hot drinks can warp trays, so avoid them while aligners are in.
  • Smilo can help you track wear time and tray changes so short removals for safe drinks don't disrupt your routine. [1, 2]

What the manufacturer says

Align Technology's Invisalign 'Use and care' instructions state that, except for cool or tepid water, you should not drink while wearing the aligners and they warn that hot drinks can warp the trays. [1]

Why flavored or colored drinks are a concern

Laboratory (in-vitro) studies that immersed clear-aligner specimens in beverages such as tea, coffee, cola and juices measured measurable color change compared with water controls, showing that aligner materials can stain under beverage exposure. [2, 3]

Those laboratory protocols used prolonged immersion (hours) rather than typical intermittent sipping, so they demonstrate the material’s susceptibility to staining but do not precisely quantify real-world staining from occasional sips. [2, 3]

What this means for flavored water specifically

None of the cited lab studies tested a single standardized 'flavored water' product; flavored waters vary in colorants, acids and sweeteners, so there isn't direct lab evidence for every formulation. Given the manufacturer instruction and the lab finding that colored beverages can stain, the practical implication is to remove aligners for anything other than cool or tepid water. [2, 3]

Cleaning and reversing stains

Some laboratory work tested cleaning agents on beverage-stained specimens and found certain cleansers reduced discoloration, but these results are from lab-stained samples and may not fully translate to everyday clinical cleaning. [2]

Using Smilo to keep your routine on track

If you need to remove trays briefly to avoid drinking flavored water, Smilo helps you log wear time, track tray changes and keep a consistent routine so short removals don't accidentally reduce daily wear below your target.
