All medical procedures come with a certain degree of risk. But teeth whitening is one of the safest and most proven ways to regain your brilliant smile. The risks associated with this procedure are minimal and not severe.  Teeth whitening commonly leads to - 1. Increase in tooth sensitivity (for a short period of time) 2. Mild gingival irritation (for a couple of days after the process) In rare cases, it may cause -  1. tooth erosion,  2. tooth mineral degradation,  3. increased susceptibility to demineralization, and  4. pulpal damage Teeth whitening has a direct impact on the patient’s oral health and hygiene. Hence, it is essential for a patient to consult a dentist before the teeth whitening process.
