Why are my teeth stained?
There are many reasons why people have stained teeth, sometimes through no fault of their own. The most common source of tooth stain of course is through food and drinks consumption. Over the years you may have consumed coffee or tea frequently or perhaps red wine, which all stain your teeth. Nicotine is another reason for having stained teeth, and even if you no longer smoke, the effects may be clearly seen on the surface of your teeth. Such stains are not removed by flossing and brushing your teeth. These types of teeth stains are called extrinsic stains and are relatively easier to remove compared to intrinsic stains which are embedded deep in the tooth structure. Intrinsic stains are caused by excessive fluoride and tetracycline intake while your teeth develop up to thirteen years of age. Other genetic factors can contribute to stubborn intrinsic stain formation. However, laser teeth whitening treatment has shown great success in removing these types of stains. In some cases multiple tooth whitening treatments are required to achieve desired whitening results.
