Quite often a smile is the first form of communication we have. When you greet someone new, you likely smile before you even say hello. If you pass a friend on the street, or see someone from your vehicle, your smile says the words you are thinking. |
Having the best smile you can makes a good impression, so it's not surprising many people look to brighten up their smile by reducing the discolouration and stains that appear over time.
Most teeth whitening formulas on the market, from toothpastes to strips to gels contain some form of peroxide. If you've been apprehensive about using peroxide based products on your teeth for health and safety reasons, you need not worry.
Peroxide is not only used in commercial applications, it's also used in many dental offices as a safe and gentle way to reduce discolouration and oxidize dull looking teeth. The amount of peroxide contained in bleaching and whitening products is about three to twelve percent, which is well within the safety range recommended by dental practitioners.
As your teeth age, they begin to weaken and are more susceptible to minor flaws, scratches and damage to the enamel. This type of naturally occurring erosion of the protective layer of your teeth allows stains to adhere directly to your teeth, and makes it difficult to simply brush them away.
Using a peroxide based formula penetrates the discoloured area and oxidizes it gently until your teeth have returned to their natural white state. While your teeth won't rejuvenate with one application, over the course of a few days to a couple of weeks, the regular use of peroxide will gradually remove any unwanted yellowness or staining of your teeth.
The type of formula you use is entirely up to you. In fact, any product, whether it's a toothpaste or whitening strips, as long as it contains some concentration of peroxide, will indeed safely whiten and brighten your smile.
