The short answer
Home whitening should be chosen by its ingredients, directions, fit, and dental suitability, because whitening products can affect teeth and gums differently.
How do peroxide ingredients work through enamel and dentine?
The active ingredients in many home systems are peroxide compounds that diffuse through enamel and dentine to break down some stain molecules. A product label or seal does not replace an examination for decay, gum disease, cracks, restorations, or causes of intrinsic discolouration.
What should you check before starting home whitening?
Check the product's active ingredient and concentration, follow its contact time, and stop if severe pain or gum injury develops. Custom trays made from dental impressions can control gel placement, while overfilled or poorly fitting trays may expose the gums.
When should a dentist assess your mouth before whitening?
Ask a dentist to examine your mouth before whitening if you have sensitivity, cavities, gum recession, pregnancy-related questions, or visible restorations. Seek care for persistent pain, ulceration, or a single tooth that darkens.
What should you ask about home whitening and sensitivity?
Ask what the product contains, whether the trays fit, how natural teeth and restorations will differ, and what plan is appropriate if sensitivity occurs.
Frequently asked questions
Can this problem have more than one cause?
Yes. An examination distinguishes tooth, gum, bite, medication, and general-health causes that can look similar.
What will the dentist check?
The dentist will inspect the area, test nearby teeth and gums, and use imaging or other tests when the findings require them.
