White polish teeth
Professional polishing removes some surface stain and plaque, but it does not change the natural internal color of a tooth.
The short answer
Dental polishing can remove some external stains from teeth, but it is different from peroxide whitening and cannot lighten every type of discoloration. A dentist or hygienist uses a polishing cup, brush, or air-polishing system with a suitable abrasive powder or paste.
How do stains attach to the tooth surface?
Surface stains attach to the enamel pellicle and may come from foods, drinks, tobacco, or pigment-producing plaque. Internal discoloration lies within enamel or dentin, where polishing cannot reach it.
What should be checked before polishing your teeth?
The clinician first checks for cavities, cracks, calculus, gum inflammation, and existing restorations before polishing. Afterward, maintain the result with brushing, interdental cleaning, and a review of habits that stain the tooth surface.
When does a dark tooth need dental assessment?
Arrange an examination if one tooth is dark, the color change appeared after injury, or the surface has pits or sensitivity. These findings can indicate decay, pulp damage, enamel defects, or a restoration rather than removable stain.
What should you ask about tooth discolouration?
Ask whether the discoloration is external, internal, or caused by a filling or crown. Ask whether polishing, professional whitening, restoration replacement, or treatment of disease addresses the actual cause.
Frequently asked questions
Does polishing make teeth permanently white?
It can reveal the natural color beneath surface stain, but it does not permanently alter the internal tooth color.
Can polishing remove yellow teeth?
It may remove yellow-brown surface deposits, but natural dentin color or internal discoloration needs a different assessment.
