Can I drink an energy drink with Invisalign?

No — both Invisalign patient guidance and major orthodontic advice say you should remove your aligners before drinking energy drinks; only water is considered safe to sip with aligners in. [1, 2]

Quick takeaways

• Only water is recommended while aligners are in; remove aligners for energy drinks.
• Laboratory tests show energy drinks can cause measurable staining and chemical changes to aligner materials.
• Removing aligners for colored, acidic, or sugary drinks protects both aligner appearance and your teeth. [1, 3]

Why manufacturers and orthodontists say no

Invisalign patient guidance states that you should remove your aligners before consuming coffee, sparkling or sugary drinks and that only water is safe to drink while aligners are in. [1]

The American Association of Orthodontists similarly advises that tap water is the only beverage safe to drink with aligners in and recommends removing aligners for other beverages to avoid trapping sugars and acids against teeth and to prevent staining. [2]

What the laboratory evidence shows

In-vitro studies exposing aligner material samples to beverages including energy drinks (for example, Red Bull in one laboratory protocol) found measurable color changes and chemical alterations to polyurethane-based aligner materials under immersion conditions. [3, 4]

These are laboratory immersion experiments on materials, not clinical trials. They demonstrate that some beverages can stain or change aligner material when specimens are heavily exposed, but they do not measure how brief, intermittent sipping during normal wear affects appearance or treatment outcomes. [3, 4]

Practical advice you can use today

Because manufacturer and professional guidance treat only water as safe with aligners in, the practical step is to remove your aligners before drinking an energy drink and either rinse your mouth or brush before reinserting if the drink contained sugar or acid. [1, 2]

If you drink colored or acidic beverages while aligners remain in, you risk visible staining of the trays and trapping sugars/acids against tooth enamel—reasons cited by the guidance even though direct clinical trials measuring resulting decay or treatment changes are not provided in these sources.

How Smilo can help you manage wear time around drinks

If you worry about keeping accurate daily wear while removing aligners for meals or drinks, Smilo makes it easier: use the app’s wear-time tracking to log when you take trays out and when you put them back in, set reminders for tray wear targets, and track tray-change timing so short removals for an energy drink don’t unintentionally reduce your daily total.
