Do you know if the tooth is discolored?

Everyone wants a white, healthy tooth. However, a variety of factors can cause discoloration of the teeth, making people “shy”. The American Fun Science Network recently published a summary of the various causes of tooth discoloration.

There are two major factors in the discoloration of teeth: exogenous and endogenous. Dr. Justin Phillips, an American dental expert, said that the primary cause of yellowing of teeth is lifestyle. Smoking, drinking coffee, drinking tea and chewing tobacco are the most likely to cause yellowing of the teeth. Tar and nicotine in cigarettes are the main culprit in causing yellowing of the teeth. Dark (highly pigmented) foods and beverages can also contaminate teeth, such as cola, chocolate, soy sauce, vinegar, pasta sauce and curry, which can cause enamel coloring, as well as fruits and vegetables such as grapes, blueberries, cherries, beets and pomegranates. May cause discoloration of the teeth. Acidic foods and beverages can erode the enamel, making it easier for pigments to adhere to the teeth. Tannins in wine and tea enhance the combination of pigment and enamel, causing discoloration of the teeth. New research has found that drinking milk while ingesting such foods can reduce the risk of tannins and reduce the chance of tooth decay. Certain drugs, such as liquid iron supplements, can color teeth. Brushing your teeth infrequently and not using floss to clean your teeth can also cause plaque to accumulate and yellow your teeth.

Experts at the Mayo Clinic say that exogenous stains on the surface of the teeth are easily removed, but endogenous stains that occur inside the teeth (dentin) cannot be removed. Many drugs can cause permanent coloration of the teeth. For example, taking tetracycline before the age of 8 can cause the teeth to turn brown. Pregnant women taking tetracycline at the 4th month of pregnancy or during lactation can also cause the child to have tetracycline teeth. The use of chlorhexidine-containing mouthwash in adulthood, although it can reduce bacteria and treat gingivitis, can also cause discoloration of the teeth. Treatment of the acne drug minocycline (tetracycline derivatives) can also cause discoloration of the teeth. In addition, chemotherapy, head and neck radiation, taking antihistamines, antipsychotics, antihypertensive drugs, etc. can sometimes lead to yellowing of the teeth.

Dr. Phillips said that although fluoride can enhance enamel to prevent dental caries, excessive fluoride intake can cause white streaks or brown spots on the teeth. In addition, a variety of dental filling materials such as amalgam dental fillings can also cause teeth to darken. Dr. Edita Otellka, a Massachusetts dental specialist, said other factors such as genetic factors (such as dentin or enamel dysplasia), age, disease, and injury can also cause discoloration of the teeth. As you age, your enamel will become thinner and your teeth will be more yellow.

Dental experts say that in order to keep your teeth white, you should develop good oral hygiene habits in addition to eating and not smoking. In addition, see the dentist every six months.
