Can whitening products irritate teeth or gums?
A HiSmile whitening product can irritate gums or increase sensitivity when its ingredients, fit, or use do not suit your mouth.
What factors affect the risk of whitening irritation?
Potential problems depend on the peroxide concentration, contact time, tray fit, existing cavities, gum recession, enamel wear, and how often it is used. Sensitivity occurs when bleaching agents move through enamel and dentine toward the pulp, while leakage onto gums can irritate them.
What should you do if whitening causes pain or burning?
Stop if you develop significant pain, burning, ulceration, or persistent sensitivity, and rinse away remaining product. A dentist can check for decay, cracks, exposed root surfaces, gum disease, and restorations before recommending a whitening method.
When do whitening side effects need urgent dental advice?
Seek care for severe or persistent pain, white or peeling gum patches, swelling, or a tooth that becomes painful to bite. Do not whiten over untreated decay or unexplained tooth pain.
What should the dentist assess before whitening?
Ask whether your teeth and gums are suitable, what concentration and wear time apply, and how existing restorations will look afterward. Ask how to manage sensitivity and whether a custom tray or another treatment is more appropriate.
