Why can natural teeth become yellow or brown?

Natural teeth can look yellow or brown because of surface deposits, food and tobacco stains, enamel thickness, dentin color, aging, fluorosis, trauma, or medicines taken during tooth development. Whitening changes some tooth color but does not bleach fillings, crowns, veneers, or bonding.

What should you do before starting tooth whitening?

Start with an examination and professional cleaning when deposits are present, then discuss dentist-supervised peroxide treatment if the enamel and gums are healthy. Reduce new staining by cleaning between teeth, brushing with fluoride toothpaste, and limiting frequent exposure to staining drinks.

When should dental problems be treated before whitening?

Seek care before cosmetic whitening for pain, cavities, gum bleeding, cracks, or one tooth that changed color. A tooth with internal discoloration may require root canal treatment or internal whitening rather than ordinary strips.

What should you ask about stains and whitening results?

Ask what caused the discoloration, which surfaces can change color, whether existing dental work will need replacement for a match, and how sensitivity can be prevented.
