Glow-up
A 6% hydrogen peroxide product depends on its formulation, contact time, application, and your dental health.
The short answer
Follow the product directions, keep gel off the gums, and do not combine whitening products.
What does peroxide whitening do to tooth colour?
This question concerns the anatomy, mechanism, or treatment behind the symptom or dental product. A clinical examination identifies findings that cannot be determined from wording alone.
What should you do if whitening causes burning?
Stop for burning, gum blanching, or marked sensitivity, and obtain dental advice before continuing.
What should you ask a dentist before continuing whitening?
Ask what structure or material is involved, which examination or imaging is needed, what treatment choices exist, and what signs require prompt review.
Frequently asked questions
Can this be diagnosed from symptoms alone?
No. Similar symptoms can arise from different dental tissues, so examination and testing may be needed.
