Stained and discoloured teeth can be lightened using teeth whitening procedures, some can be done in office and some can be done with take home whitening kits. Dentists recommend professional whitening for safety and best results.

What is involved?

Depending on the technique, teeth whitening can involve either one or multiple visits.

Whitening is also available for artificial teeth, such as crowns, caps, or dentures. This is known as non-vital bleaching.

How long does it last?

Teeth whitening is not permanent. The longevity of teeth whitening will depend on eating habits. Tea, coffee, and smoking should be avoided as they stain and discolour teeth.


Regardless of the treatment, it is possible for the gums to react to the chemicals, even burning. Tooth whitening should be done only under a dentist’s care or recommendation as he or she can offer controlled conditions and safe, effective treatment.
