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 DIAGNOSED?
Symptoms include stains on the enamel. They can range from white streaks to yellow tints or brown spots and pits. If the enamel has worn away, and dentin is showing through, you may notice a yellow tint. No special tests are needed. A dentist or other dental professional can diagnose tooth discoloration by looking at the teeth.
HOW IS STAINED TEETH TREATED?
Getting rid of Stained Teeth incorporates a strict hygiene routine. Brushing twice a day, washing mouth post every meal, eating calcium rich foods and also reducing caffeine and nicotine. Whitening toothpastes may also be suggested by your dentist here.
