How to clean my teeth white
Daily plaque removal keeps teeth clean, while whitening treatment changes certain stains but cannot whiten fillings or crowns.
The short answer
Brush twice daily with fluoride toothpaste, clean between teeth, and have deposits professionally removed; whitening is a separate treatment for suitable natural teeth. Cleaning removes plaque and calculus, while whitening changes the color of some natural tooth stains.

What is the direct answer?
What does this question mean?
A yellow or dull appearance may come from plaque, calculus, surface stains, or the natural color of dentin beneath enamel. Tooth-colored fillings, crowns, veneers, and implants do not respond like natural enamel to peroxide whitening.
What can you do next?
Use a soft brush, fluoride toothpaste, and interdental cleaning, and limit frequent staining drinks or rinse after them. A dental hygienist can remove calculus and stain; a dentist can check the enamel, restorations, cavities, and gum health before discussing whitening.
When should you seek dental care?
Arrange care for bleeding gums, sensitivity, cavities, rough deposits, persistent bad breath, or a single tooth that darkens. Examination is also needed before whitening when you have untreated decay, gum disease, cracks, or extensive restorations.
What should you ask the dentist?
Ask whether the color is caused by deposits, surface stain, internal discoloration, or a restoration. Ask whether cleaning alone will help, whether whitening is appropriate, and how existing fillings or crowns will be matched.
Frequently asked questions
Can brushing make teeth naturally white?
Brushing removes plaque and some surface stain, but it does not change the underlying natural shade of enamel and dentin.
Will whitening whiten a crown?
No. A crown does not change color with peroxide in the same way as natural tooth structure.
