Tooth whitening is a very effective way of lightening the natural color of teeth without compromising the tooth surface in any way. The procedure can be done in one hour in the clinic with or without lasers. The cost of whitening depends on the existing color of the natural teeth. Darker teeth will require more number of visits to get the desired result. A professional cleaning is mandatory before tooth whitening This process cannot result in a complete change of color, but will lighten the existing shade of white. It is not advisable to whiten teeth for children below 18 years and for pregnant or nursing women.
Laser Tooth Whitening can be done only in the dental office exclusively. The difference with Lasers is improved effectiveness due to enhanced action of the bleaching material activated by the Laser. The concentration level of the bleaching material is also higher leading to a better result. Laser teeth whitening is more expensive and is recommended for individuals with dark to very dark teeth and those with discolored teeth due to continued nicotine usage.
