What causes tooth discolouration?
There are many causes. The most common factors include aging and the consumption of substances such as coffee, tea, cola, tobacco, red wine and the like. During tooth formation, the consumption of tetracycline, certain antibiotics or excessive fluoride may also cause tooth discolouration.
Are there any side effects?
Sensitivity during the treatment may occur with some patients. Light generates a small degree of heat, which is the usual source of discomfort. On rare occasions, minor tingling sensations can be experienced immediately after the procedure but always quickly dissipate. You can also ask your dentist to supply you with anti-sensitivity toothpaste for use prior to treatment.
