What Causes Yellow Teeth?


One of the first things people will notice is your smile. Everyone would like to have nice bright teeth, but unfortunately some people have teeth which are not so white. Yellowing discolored teeth are a problem for many people.

Your discolored teeth may be the result of genetics. If your relatives have discolored teeth chances are good so will you. Its probably a result of the enamel layer on the teeth being thinner thus allowing the yellow dentin layer of the teeth to be more visible.

Discoloration of teeth may come with aging. As you age the outer layer of enamel on the teeth can wear away and this will allow the yellow dentin layer to show through.

Certain foods and drinks can stain your teeth. Included in this group are coffee, tea, colas, sodas, sports drinks, wine, juice, and drinks with high acidity. Candies which are colored and brightly colored popsicles can stain teeth. If food colors your tongue there is a good chance it is going to stain your teeth. Drink water and swish it around in your mouth to remove some of the acids and color. Other foods which can stain teeth are berries, apples and potatoes.

Too much fluoride can cause yellowish stains on teeth. In addition to fluoride in the water it can be found in supplements taken by mouth and in toothpaste.

Everyone is aware that smoking and chewing tobacco is unhealthy. This will cause staining on your teeth so try to stop using these products.


Medication taken for high blood pressure and antipsychotic drugs and antihistamines may cause teeth discoloration.

If pregnant women have been given tetracycline or doxycycline their baby may have yellow staining when the baby develops permanent teeth. Also if these medications are given to children under eight their permanent teeth may have some staining when they come in.

Chemotherapy and radiation to the head or neck may cause some discoloration of teeth.

If you have some old silver fillings these may cause the look of a gray black color to the teeth.

Poor oral hygiene can be a big contributor to discolored teeth. Not brushing properly and flossing permit the stains from foods and drinks and tobacco to develop on the teeth. Inadequate brushing and flossing allows plaque to build up on the teeth.

See your dentist on a regular basis. Have your teeth cleaned professionally by the dental hygienist every 6 months or as often as advised by your dentist.

If your discolored teeth are making you unhappy there are options available for teeth whitening. Some products are over the counter and some are done in the dentist’s office. One of these options may be of benefit to you.
