What causes tooth discoloration?
Tooth discoloration can be of two main types: extrinsic (caused by substances we introduce into our mouths) and intrinsic, (caused by conditions in the body which influence tooth formation or color). Predisposition to tooth discoloration Some factors make tooth discoloration more likely for some people, both children and adults: Tiny enamel defects that allow staining substances to accumulate. Insufficient saliva, which normally helps us clear food remains and early plaque. Saliva output can be decreased by an infection or obstruction in the mouth, by some diseases, by radiation to the head and neck, and by many medications. Poor dental hygiene which is a voluntary factor, allowing food particles to linger, plaque to build up, and tartar to form, all of which creates brown or black stains. Extrinsic discoloration There are many things we put in our mouths which slowly discolor our teeth.
There are many causes. The most common include consumption of foods, coffee, tea, wine, sodas and smoking. In other words, our teeth naturally get more and more stained as time goes on and we continue to live our lives. NOTE – Tetracycline discoloration and artificial dental work are usually not greatly responsive to dental bleaching.
There are many reasons for discolored teeth. Aging and the on-going ingestion of coffee, tea, cola, red wine, tobacco products, curries, etc can lead to the staining of the teeth. The ingestion of tetracycline and excessive fluoride frequently causes such severe staining that extended treatment lengths and perhaps more aggressive means may be required. Traumatized and non-vital teeth that are discolored can also be whitened, but usually require a more invasive procedure performed by a dentist.
