This post from Durham Dental Group is for people with stained teeth. Do you think your teeth are too stained for teeth whitening to have any effect? Think again.
There are two types of stains on teeth: intrinsic and extrinsic.
Extrinsic stains are caused by dark colored foods and drinks, smoking, and normal aging. Durham Dental Group cosmetic dentistry patients with extrinsic stains achieve great results from both in-office and take-home teeth whitening systems.
Intrinsic stains form on the inside but can be seen from the outside. Tetracycline, excessive fluoride, trauma, and aging can cause intrinsic staining for unfortunate men and women. Though these stains are harder to remove, many patients with intrinsic staining can whiten their teeth with take-home whitening kits. The process often takes longer, but with persistence, intrinsic stains can be lightened.
