What is gingival barrier protection gel used for?

Gingival barrier gel protects your gums during whitening—keeping the whitening gel off sensitive gum tissue to reduce discomfort and irritation. Works for in-office and at-home treatments.

How does the barrier gel work?

Apply along gumline before whitening. Hardens in ~2 seconds to form a secure seal that stays in place—protects gums while whitening teeth.

Is it safe for at-home use?

Yes—our gingival barrier gel is safe for at-home use when used as directed. Made from gentle, silicone-like ingredients, it's comfortable to wear and easy to remove. Many users have had positive results with it.

Can this gel help with tooth sensitivity during whitening?

Yes—many users say it helps prevent sensitivity during whitening. One even shared they "had no sensitivity at all" when using it. The barrier keeps the whitening gel off your gums, protecting sensitive tissue and reducing discomfort.

How should I store the gel to maintain its effectiveness?

Store in a cool, dry place away from sunlight and heat (below 30°C / 86°F). Do not freeze or refrigerate. Keep tube closed. Avoid hot cars or windows with temperature swings.

No more “burnt” white gums!

This protection gel made it possible for me to use the teeth whitening gel from my dentist. I tried several times in the past but always ended up with an extremely painful burning sensation and white gums within the first few seconds. I would recommend this for anyone who uses teeth whitening gel.

Good

Other reviews said that it was runny. Wasn’t runny to me.🤷🏾‍♀️ will update this review once I try it on a client. UPDATE: so I actually tried this on a client for the first time and yes it is runny. Recommend doing small areas at a time then cure and go to the next area
