- Teeth staining or discoloration may be caused by the aging process, smoking, tartar, or by drinks and foods such as coffee and red wine.
- Professional teeth bleaching at the dentist’s office is the most common form of teeth whitening. Laser whitening is a new, quicker, and more effective option.
- Tooth whitening may have side effects such as tooth sensitivity, sore throat and pain along the gum line.
The effects of whitening are thought to last up to three years. However, this will vary from person to person. The effect is less likely to last as long if you smoke, or eat or drink products that can stain your teeth.
