Laser Whitening
Using a laser with a whitening gel, this is an in-office bleaching system. The translucent bleaching gel is applied to the teeth and a laser light is used to activate the crystals to absorb the energy from the light and penetrate the teeth enamel to increase the lightening effect on the teeth. The length of time in the cosmetic dentist's chair depends on the degree of discoloration you have. The advantage of this laser technique is that one visit is usually all it takes for a bright smile.
The procedure takes about an hour to an hour and a half. A dentist will apply a peroxide-based bleaching solution to your teeth, which is then activated by a special blue high intensity light or laser. It may require more than one treatment depending on the degree of whitening needed.
There are a number of reasons why you might get your teeth whitened. Everyone is different; and just as our hair and skin colour vary, so do our teeth. Very few people have brilliant-white teeth, and our teeth can also become more discoloured as we get older.
Your teeth can also be stained on the surface through food and drinks such as tea, coffee, red wine and blackcurrant. Smoking can also stain teeth.
Calculus or tartar can also affect the colour of teeth. Some people may have staining under the surface, which can be caused by certain antibiotics or tiny cracks in the teeth which take up stains.
For people with very sensitive teeth, sometimes an alternate tray-type method is used. The whitening tray is worn only for a couple of hours each day, instead of overnight. This method may cause less sensitivity than traditional overnight tray use or laser whitening, however, it may take five weeks or longer to achieve the desired effect.
There is now laser whitening or "power whitening". During this procedure a rubber dam is put over your teeth to protect the gums, and a bleaching product is painted onto your teeth. Then, a light or laser is shone on the teeth to activate the chemical. The light speeds up the chemical reaction of the whitening product and the colour change can be achieved more quickly using this procedure. Laser whitening can make teeth up to five or six shades lighter.
The other procedure is called professional bleaching which is the most common form of tooth whitening. Your dentist will be able to tell you if you are suitable for the treatment, and will supervise it if you are. First, the dentist will put a rubber shield or a gel on your gums to protect the soft tissue. They will then apply the whitening product to your teeth, using a specially made tray which fits into your mouth like a gum-shield.
