The answer is no. When the whitening process, is carried out under the control of the dentist and with the use of modern and approved whitening agents, it is completely safe. Whitening does not destroy tooth enamel or damage the teeth, as long as the whitening materials are the ones used in the in-office procedure and home whitening kit recommended by your dentist. The only symptom that can occur is a slight sensitivity of the teeth, which is temporary, usually lasts 2-3 days and can be treated with special desensitizing agents provided by the dentist.
