A regular dental check up is important to help keep your teeth and gums healthy. You should have a regular visit at least every 6 months or as recommended by your dental professional.
Maintaining good oral hygiene is one of the most important things you can do for your teeth and gums. Healthy teeth not only enable you to look and feel good, they make it possible for you to eat and speak properly. Daily preventive care (brushing and flossing) will help stop problems before they develop and is much less painful and expensive than treating conditions that have already progressed.
You already know that whitening works, but do you know how?
Stains on teeth can be classified in one of two ways: extrinsic or intrinsic. Extrinsic stains appear on the surface of your teeth. Intrinsic stains live between the microcracks in your enamel and deep within your dentin (the layer of your tooth underneath your enamel). Whitening toothpastes and mouth rinses may be able to remove some of the extrinsic stains on your teeth. But only teeth whitening agents can remove the stubborn extrinsic stains and the unsightly intrinsic stains that cause your teeth to look discolored.
Opalescence gels contain an active whitening ingredient (either carbamide peroxide or hydrogen peroxide) that penetrates your enamel to get to discolored molecules. Oxygen molecules from the whitening agents react with the discolored molecules in your teeth, breaking the bonds that hold them together. The oxygen molecules spread, whitening the entire tooth. As a result, you are left with a brighter, whiter smile.
