There are several causes of tooth discolouration, the most common being aging, staining substances (e.g., coffee, tea, cola, tobacco), trauma, tetracycline (antibiotic) staining, excessive fluoride and nerve degeneration.
Teeth whitening is a simple and effective process that lightens discolouration of enamel and dentin. The system uses a peroxide-based gel retained in a custom fitted appliance that is worn over your teeth.
The tooth-whitening system is ideal for people who have healthy, unrestored teeth and would like to have a whiter, brighter smile. Darker stains, such as those caused by antibiotics, take longer to respond to treatment.
Results are usually seen after 2 to 3 treatments. The best results generally occur when the process is continued for 10 to 14 treatments.
Whitened teeth will always be lighter than they were. You may need to periodically repeat the process every 6 to 12 months for 3 to 4 treatments to keep your natural teeth your desired whiteness.
