WHAT IT IS
Teeth whitening is, by far, the most popular cosmetic dental procedure. It brightens your teeth by removing stains caused by foods and beverages such as berries, coffee, wine, tea etc. Whitening removes stains by polishing the surface of the tooth and this is why some over-the-counter toothpastes can claim “whitening”.
Teeth bleaching refers to lightening a tooth from the inside-out. It brightens the inside (dentin) of the tooth, thereby making the whole natural tooth whiter. Bleaching sends peroxide into the tooth to whiten the organic material from the inside.
