Teeth whitening is painful
Whitening can cause short-lived sensitivity or gum irritation because peroxide affects fluid movement through dentine and can contact gingiva.
What is the direct answer?
Whitening can cause short-lived sensitivity or gum irritation because peroxide affects fluid movement through dentine and can contact gingiva.
What does this question mean?
Peroxide can pass through enamel into dentine and stimulate the pulp. Poor tray fit, excess gel, exposed roots, cracks, cavities, and sensitive teeth increase irritation.
What can you do next?
Stop if pain is sharp or gums burn, rinse away gel, avoid temperature extremes, and contact the clinic about an adjusted plan.
When should you seek dental care?
Seek care before continuing when pain is severe, lasts, affects one tooth, or occurs with a cavity, crack, swelling, or ulcer.
What should you ask the dentist?
Ask whether a cavity, crack, recession, or exposed dentine explains the pain.
