See a dentist for sensitivity, erosion, bleeding, a dark single tooth, or persistent stains.
What should you ask the dentist?
Ask whether the colour is surface staining or an internal change.
Frequently asked questions

Can home care replace an examination?
No. Home care may reduce irritation, but it cannot diagnose infection, decay, gum disease, or structural problems.
