Can a dentist whiten my teeth
Yes. A dentist can whiten natural teeth after checking your enamel, gums, fillings, crowns, and the cause of discoloration.
The short answer
Yes. A dentist can whiten natural teeth after checking your enamel, gums, fillings, crowns, and the cause of discoloration. Treatment may use professionally applied hydrogen peroxide or carbamide peroxide, in the clinic or through custom trays used at home.
How is whitening different from professional cleaning?
Dental whitening lightens stains within enamel and dentine, while cleaning removes plaque, tartar, and surface pigment. Whitening changes the shade of natural tooth structure, but it does not change the colour of porcelain crowns, veneers, or fillings.
What happens before a dentist applies whitening gel?
The dentist examines your teeth and gums, records the starting shade, treats active decay or gum inflammation, and protects the gums before applying gel. Ask whether in-office treatment, dentist-made trays, or no whitening is appropriate for the particular stains.
Which dental problems should be checked before whitening?
Arrange an examination before whitening if you have tooth pain, cavities, cracked enamel, gum bleeding, exposed roots, or strong sensitivity. Seek prompt care for swelling, fever, or pain that is worsening, because whitening does not treat infection.
What should you ask before choosing dentist-provided whitening?
Ask what is causing the discoloration, which teeth are natural, what sensitivity or gum irritation may occur, and how existing restorations will look afterward. Also ask how the gel and trays will be used and what result is realistic for your starting shade.
Frequently asked questions
Can whitening remove every stain?
No. Surface stains may improve with cleaning, while deep internal or medication-related discoloration may need another treatment.
Why can teeth feel sensitive after whitening?
Peroxide can temporarily move through enamel and irritate the tooth nerve, especially when enamel is thin or a root is exposed.
