Teeth Whitening

Tooth WhiteningTeeth whitening is the use of bleaching agents to lighten the colour of teeth. The normal colour of tooth enamel (the hard outer surface of each tooth) varies, with most teeth ranging from off-white to light yellow. Teeth may be discoloured by various factors including: surface stains from smoking or drinking tea or coffee, age, poor oral hygiene, tooth decay, tooth injuries and even some medicines.

Teeth whitening is contraindicated in certain situations and is important to have a dental professional check the teeth before considering such treatment. Not everyone is a good candidate for teeth whitening.

If you are a candidate for teeth whitening, your dentist takes a mould of your teeth to make plastic trays that have a custom fit, then gives you the tubes of bleaching gel and instructions. Gel-filled trays are worn at home anywhere between an hour and overnight. Most people need to wear the trays every day for two to four weeks. Bleaching is a perfectly safe procedure and most people are satisfied with the results.
