Discoloration can be caused by food, beverages, medications, and smoking, and in some cases is the result of disease or genetics.
External staining on the teeth occurs most often due to drinking Coca-Cola, coffee, tea or consuming blueberries, red wine and smoking tobacco products. In this case, staining is solved by limiting the amount of a certain food and professional teeth whitening.
Plaque staining is also a type of external staining that occurs with insufficient thorough oral hygiene.
The problem can be solved immediately by professional calculus cleaning and sandblasting - the result will be maintained by the patient with the proper use of toothbrushes and dental floss.
Internal staining can be caused genetically, due to disease, medications, or, most commonly, due to tooth avitality. After dental treatment, for various reasons, the tooth may take on a different, grayish color. In this case, internal whitening is indicated at the dentist.
Not all stains are pathological, so it is normal to expect that teeth will turn yellow as they age. This is due to the physiological darkening of the dentinal tissue located just below the enamel.
You can get the best course of therapy related to staining, both teeth and fillings, from your dentist.
