There has been phenomenal growth in consumer awareness since tooth whitening became a concept. Many different kinds of whitening products or systems are in the market.
Whitening toothpastes have polishing or chemical agents that help remove surface stains, even though they do not contain any tooth bleaching agent.
The over the counter whitening products such as Crest White strips contain the peroxide bleaching agent. They also need a certain degree of compliance and need to have touch-up’s after the results are stable.
The third kind of whitening is done at home, but the bleaching gel has to be dispensed professionally by a dentist. We will fabricate a whitening tray that adapts to your teeth precisely without irritating your gums.  Bleaching gel will then be applied on these trays and each product’s usage regimen varies. Compliance is also needed to achieve good results.
The last kind of whitening is called in-office whitening, and it works best for those who desire an instant result and for those who need close monitoring of their gums or tooth sensitivity. The highest concentration of the bleaching agent is used, and lasers/light/heat are often used to activate the bleaching agent.
Please note that bleaching is not for everyone. If you have bonding or tooth-colored fillings placed in your front teeth, they will stand out after you bleach, and may therefore need to be replaced. In some cases, you may want to investigate other options like porcelain veneers or cosmetic crowns if you want to change the positions and shapes of your front teeth in addition to changing their color.
