A Look at In-office and At-Home Teeth Whitening

BackMountainDentalUnfortunately, your teeth’s pearly white color can fade away. Food, drinks, and nicotine (if you smoke) can leave intrinsic and extrinsic stains that will make you teeth look yellowish or grayish. Intrinsic stains are those that are stuck in the pores of the teeth’s enamel, while extrinsic stains adhere only on teeth’s surfaces.

Extrinsic stains may be removed by over-the-counter non-bleaching products that can be applied at home. These products contain chemicals that can dislodge stains as they thicken and before they form plaque. However, they are not potent enough to extract the stains embedded deep within the enamel. In such cases, in-office dental bleaching is needed, making use of peroxide to get rid of the stains.

In-office whitening offers longer lasting whiteness, and because all the stains are taken out, the teeth appear whiter than those cleaned using only at-home whitening products. In-office dental bleaching normally takes 30 minutes to 1 hour. Getting professional dental bleaching at least twice a year helps protect your teeth from potential decay.

The most effective way to preserve the whiteness of your teeth is to avoid eating or drinking highly pigmented food and beverages. Black tea, wine, and berries are among the most common culprits of heavy teeth staining. Constant brushing may also help prevent stains from permanently sticking on teeth.
