Teeth whitening

Short answer

Whitening uses safe bleaching gels to lighten tooth color. It does not fix cavities or damaged teeth.

Simple explanation

Whitening can be done in-office in about an hour, or with custom trays at home over 1–2 weeks. Some sensitivity for a few days is normal. Results vary from person to person.

When this usually matters

It is cosmetic — check for cavities and gum health first.

When to seek dental help

Extreme sensitivity, uneven whitening, or dark spots after whitening should be evaluated.

Questions to ask your dentist

  • Am I a good candidate?
  • How white can I realistically expect?
  • How long will it last?

This is simple educational information. It is not a diagnosis and does not replace a dental examination. Your dentist may recommend something different depending on your mouth, X-rays, pain, infection, gums, bone, medical history, and clinical judgment.
