Is it safe to get teeth whitened
Teeth whitening risks depend on the peroxide strength, application time, enamel and gum condition, and whether the discoloration is inside the tooth or on
The short answer
Teeth whitening risks depend on the peroxide strength, application time, enamel and gum condition, and whether the discoloration is inside the tooth or on its surface.
How does peroxide break down tooth discolouration?
Whitening uses peroxide to break down colored molecules in enamel and dentin. Temporary sensitivity or gum irritation can occur, while fillings, crowns, and veneers do not whiten like natural teeth.
What should you do before whitening your teeth?
Have the cause of discoloration checked first, use a dental professional’s instructions, and keep gel away from the gumline. Treat cavities or gum inflammation before whitening.
Which whitening reactions require dental advice?
Stop and seek dental advice for marked pain, chemical burns, swelling, or sensitivity that does not settle. An examination is important before whitening during pregnancy, with untreated disease, or in a young patient.
What should you ask before choosing a whitening treatment?
Ask what caused the shade change, which surfaces will respond, what material is being used, and how existing restorations will look afterward.
