Get stains off teeth
Surface stains can be lifted by professional cleaning and careful polishing, while deeper discoloration may require bleaching or restorative treatment.
The short answer
Surface stains from foods, drinks, tobacco, or plaque can often be removed with professional cleaning and polishing, while deeper discoloration needs a different assessment. Whitening bleaches natural tooth structure; it does not remove tartar or change the shade of fillings and crowns.
Where do external stains collect on the tooth surface?
Extrinsic stain sits on the outer enamel surface or within plaque and calculus, often appearing brown, yellow, or dark near the gumline. Intrinsic color lies within enamel or dentin and may follow aging, trauma, developmental defects, or medication exposure.
What daily care can help prevent stains from returning?
Brush twice daily with fluoride toothpaste, clean between the teeth, and limit repeated exposure to staining drinks or tobacco. A dental hygienist can remove calculus with instruments or ultrasonic scaling and polish remaining external deposits; do not scrape the enamel with metal tools.
When does a tooth stain need assessment by a dentist?
Arrange care when a stain remains after cleaning, appears on one tooth, is joined by a hole or pain, or changes rapidly. A dark line at the gum, bleeding, bad breath, or loose teeth can accompany gum disease and needs assessment.
Is the colour caused by stain, decay, or a restoration?
Ask whether the color is plaque, calculus, external stain, decay, intrinsic discoloration, or a restoration. Ask whether cleaning, bleaching, bonding, a veneer, or monitoring is the least invasive way to address it.
Frequently asked questions
Can baking soda remove stains?
A small amount in toothpaste may polish some surface stain, but abrasive powders and forceful brushing can wear enamel and should not replace dental cleaning.
Why is one tooth darker than the others?
A single dark tooth can reflect trauma, pulp changes, decay, or a restoration and should be examined before whitening.
