How Does Teeth Whitening Work?




HOW DOES TEETH WHITENING WORK?


Teeth whitening involves bleaching stains on teeth to make them whiter. Teeth whitening can’t make your teeth paper white like in the movies, but it can lighten the existing colour of teeth by many shades.  Teeth whitening involves the use of an agent to remove stains on the enamel of the teeth caused by lifestyle. This is where an oxidation reaction that breaks apart the staining compounds and lifts them from the teeth.

 

Teeth whitening bleaches the stains on the surface of the teeth it does not whiten enamel, no matter how strong the lamp or the gel, whether done by a technician or a dentist.  Once there are virtually no more stains to whiten this is referred to as ‘Maximum Results’.  The maximum result teeth whitening can achieve is the return the teeth to the colour they were grown.  The average person has 5-14 shades of staining on the surface of their teeth.  That is an average person with an average diet.  This doesn’t refer to someone who uses teeth whitening products regularly nor it is a heavy smoker it is just your average person.  


These in chair systems use peroxide or non peroxide gels, combined with a high intensity light to accelerate the whitening reaction. The in-office teeth whitening treatment can achieve about five to fourteen shades of whitening after only two twenty-minute treatments.


Technician supervised systems have advantages when compared to over-the-counter teeth whitening products. The main advantage of the technician supervised system is that maximum results can be achieved in a one hour sessions rather than repeated application over many days or even weeks.


Teeth whitening isn’t permanent. It can last from several months to up to two years; this varies from person to person depending on their lifestyle. Basically, teeth whitening won’t last as long if you smoke or drink red wine, tea or coffee, which can all stain your teeth.  Teeth whitening won’t work on dentures, crowns, fillings or veneers.
