How long after teeth whitening does sensitivity last
Sensitivity after teeth whitening usually settles within a few hours, although a treated tooth can remain sensitive for a day or two.
What is the direct answer?
Sensitivity after teeth whitening usually settles within a few hours, although a treated tooth can remain sensitive for a day or two.
What does this question mean?
Whitening temporarily makes dentine tubules more responsive to temperature and touch as peroxide moves through enamel. It differs from pain caused by decay or a crack.
What can you do next?
Use desensitising toothpaste, avoid hot or cold drinks briefly, and follow the product contact time. Do not add applications when sensitivity starts.
When should you seek dental care?
Arrange care if pain is severe, lasts beyond the expected recovery, affects one tooth, or occurs with swelling or pain on biting.
What should you ask the dentist?
Ask whether the tray fit, exposed dentine, decay, or gum recession is contributing and which schedule is appropriate.
