I am using my last set of Invisalign trays for teeth whitening. I bought carbamide peroxide gel, and I use it as directed. My dentist charges too much for whitening and will not give me a discount. Today is my second week of whitening, and now my gums are burning. How do I know whether the trays or the bleaching gel make my gums burn? Have I ruined my gums? Thank you. Sakura
Thank you for your question. We recommend pausing your teeth whitening and getting an exam from your dentist.
Are Invisalign Trays or Bleaching Gel Making Your Gums Burn?
Whether Invisalign trays or bleaching gel is making your gums burns depends on several factors, including:
- Bleaching trays – Although the Invisalign trays may seem to fit your teeth, any bleaching gel oozing from the top of the aligners will burn your gums. Custom bleaching trays from your dentist will keep the gel on your teeth and away from your gums.
- Bleaching gel strength – The strength of the bleaching gel may be too potent for your teeth and gums. A lower-strength gel may help.
- Bleach gel contents – The bleaching gel may contain irritants that make your gums burn. Check the ingredients.
- Too much bleaching gel – Overfilling the trays or leaving the gel on your teeth longer than directed can cause teeth sensitivity and burning gums.
Have Your Ruined Your Gums with Bleaching Gel?
The burns on your gums from bleaching gel will turn white and may peel, but you should recover in a week or two. Still, discontinue whitening until you know why your gums are burning.
When Can You Resume Teeth Whitening?
You can resume teeth whitening when you know that you have bleaching trays that will not ooze out any gel and bleaching gel that is not too potent for our teeth and gums. We recommend the following:
- Schedule an exam to ensure you do not require treatment from a dentist to help your gums heal.
- Check other dental practices for their teeth whitening costs.
- Only use custom trays made for bleaching our teeth.
- Start with a low-strength bleaching gel to avoid burning gums and sensitive teeth.
