What is the direct answer?
Tooth polishing is a professional cleaning step for selected surface stains; abrasive home powders can wear enamel or expose dentine.
What does this question mean?
Polishing uses a rotating rubber cup or brush with a dental polishing paste to smooth deposits and some extrinsic stains on enamel. It does not whiten the internal tooth color or remove tartar, which must be removed with scaling instruments.
What can you do next?
Brush twice daily with fluoride toothpaste, clean between teeth, and reduce repeated exposure to staining drinks. A dental hygienist can identify whether discoloration is plaque, calculus, an external stain, or a change inside the tooth.
When should you seek dental care?
Arrange an examination before trying abrasive products if teeth are sensitive, translucent, chipped, or heavily stained. Seek care for a new single-tooth color change, pain, or bleeding gums rather than polishing over it.
What should you ask the dentist?
Ask what type of stain you have, whether scaling or polishing is indicated, and whether enamel wear or decay is contributing. Ask about whitening options if the color lies within the tooth rather than on its surface.
Frequently asked questions
Can baking soda polish teeth?
It is abrasive, and repeated or forceful use can contribute to surface wear; use a formulated toothpaste instead.
Does polishing whiten teeth?
It can remove some external stain, but it does not change the natural internal shade of enamel or dentine.
