The short answer
Teeth whitening uses peroxide to break down some stain molecules within enamel and dentin. A dentist can first check for decay, gum disease, cracks, restorations, and the type of discoloration.
What is the direct answer?
What does this question mean?
Surface stains come from pigments such as coffee, tea, tobacco, or food, while internal color can arise from aging, trauma, or tooth development.
What can you do next?
Professional trays, in-office peroxide, or a regulated home product may be selected after an examination; brush with fluoride toothpaste and avoid abrasive powders.
When should you seek dental care?
Seek an examination before whitening if teeth hurt, gums bleed, a tooth is darkening alone, or fillings and crowns are visible in the smile.
What should you ask the dentist?
Ask what caused the discoloration, whether existing restorations will change color, and how sensitivity will be managed.
