Bleaching gel application and tooth sensitivity
Part of Immune system & allergy, Mouth & dental clinical trials.
This study tests two different ways of applying a gentle bleaching gel to see if one causes less tooth sensitivity. It's for people who want to whiten their front teeth and have no history of sensitivity or prior whitening.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have at least 8 upper front teeth (from canine to canine).
- You are 18 years or older.
- Your front teeth are naturally darker than a C2 shade (your dentist can check this).
- You are in good general and oral health — no gum disease, cavities, or visible plaque on the teeth being whitened.
- You have never had your teeth professionally whitened, and you do not smoke or use painkillers regularly.
