Professional cleanings sometimes are very effective in removing extrinsic or superficial stains on the surface of the teeth. Nevertheless, if this is doesn’t provide an optimal cosmetic change, or is ineffectual, the sole options are to either bleach the teeth, or cover the external surfaces with veneers.
Bleaching is the most common system dentists use to restore teeth that have either a yellow or grey colour. A number of strategies are available now to reach brighter teeth using bleaching; one methodology requires the dentist to make models of your teeth to make customized trays that will keep the bleaching agent in contact with your teeth.
If these trays are worn every day for the prescribed period, by the end of two weeks, there is generally an obvious improvement – often even within the first a few days. This technique places the control over the whitening in your hands, and you will continue using it until you reach an acceptable shade of whiteness. Your dentist may wish to see you periodically to check on your progress.
Another system involves a clinical treatment using bleaching agents that are turned on, or speeded up, using a source of light. Sometimes, it may be a laser, while other systems use non-laser lights.
Bleaching the teeth is a process that requires patience to reach perfect results, and it’s vital to know that not every system delivers satisfactory results. As more and more bleaching agents appear in stores and pharmacies, it is highly recommended that you use only products immediately recommended, administered and / or monitored by your dentist.
