Dr. Hugh Flax from Flax Dentistry answers a readers question about whitening sensitive teeth.
Q: Can I whiten my teeth even if I have sensitive teeth?
A: Whitening products may worsen sensitivity, so it is important to get to the root cause of sensitivity before you start a whitening treatment. For instance, a cracked tooth can cause sensitivity and should be repaired before whitening. If you have sensitive teeth due to thinning enamel, avoid high concentrations of whitening chemicals and opt for lower concentrations. You may also need to cut down on the frequency with which you whiten, whether at home or at the dentist’s office.
