Teeth can become discolored by stains on the surface or by changes inside the tooth. There are three main types of tooth discoloration:
• Extrinsic — This occurs when the outer layer of the tooth (the enamel) is stained. Coffee, wine, cola or other drinks or foods can stain teeth. Smoking also causes extrinsic stains.
• Intrinsic — This is when the inner structure of the tooth (the dentin) darkens or gets a yellow tint. You can get this type of discoloration if:
• Age-related — This is a combination of extrinsic and intrinsic factors. Dentin naturally yellows over time. Foods and smoking also can stain teeth as people get older.

HOW IS STAINED TEETH TREATED?
The treatment of Stained Teeth involves medication toothpaste, medication and often, surgery to remove the stains from the teeth.
DID YOU KNOW?
There are also cosmetic restorations that can be used to cover a heavily stained or discolored tooth, regardless of the source. A porcelain veneer, for example, is a thin layer of dental porcelain that’s permanently bonded to the front of a tooth.
