Teeth whitening is the removal of stains and discolorations from the enamel and dentin. The outer layer of the tooth is enamel, and beneath the enamel is dentin. Enamel is thin and typically much lighter in color, while dentin is darker in color and makes up the bulk of the tooth. Enamel can be discolored over time simply from age, but also from outside sources like coffee, tea, tobacco, and other foods and beverages. Also, as we age, our enamel thins, causing more dentin to show through, making the overall appearance of the tooth look darker.
Whitening your teeth removes these stains and discolorations, giving you a whiter, brighter smile. The active ingredients in Opalescence whitening gels pass into your teeth to oxidize the discolored molecules deep down in your teeth, removing stains and whitening your smile. Our original, patented formula contains PF (potassium nitrate and fluoride) and is sticky and viscous, so it stays where it’s placed. This unique feature prevents the gel from seeping out during treatment, ensuring both the gel and tray stay in place and work effectively for the duration of your treatment.
