Top 10 Causes of Teeth Stains

Teeth discoloration is one of the few facial defects that can make you very uncomfortable as well as unattractive. Not only does it make it tough to smile in public, but it also lowers self-esteem and can lead to very low moods.


When most people see a guy with yellow or discolored teeth, the first thought that usually jumps to mind is that the person does very little or nothing in the way of oral hygiene.​

Granted, poor oral hygiene is one of the causes of teeth stains and teeth discoloration. But it is important to remember that it is not the only cause but simply one of some other physical and chemical causes.

In fact, most of the time the teeth discoloration does not even result from any fault of the person in question.​ Teeth stains and, by extension, teeth discoloration, can take on any of some colors.

However, brown and yellow discolorations are the most common, and it is, therefore, understandable why most people assume that they are the only two forms. Below is a list of the top ten most common factors that cause teeth stains.​


Poor Oral Hygiene

When you fail to brush and floss your teeth on a regular basis, calculus/tartar and plaque can accumulate on their surfaces. The more these accumulate, the yellower your teeth will appear and if this is allowed to go on for long, your teeth may get permanently discolored.

To be specific, old age can cause teeth discoloration. According to research, the older one grows, the more discolored his or her teeth become. However, this is only true after a certain age from where one starts to approach old age or the sunset years. 


Old age yellowing of teeth is usually attributed to the wear and tear of the teeth over time.


Foods and Beverages

Some dark colored fruits and vegetables along with some beverages such as coffee, cola, tea and red wine have been known to cause the staining and discoloration of the teeth.

Foods and Beverages

Acidic foods, such as citrus fruits, erode the enamel on the tooth making it thin and translucent. The yellow dentin within then becomes more visible, and the entire tooth appears to be discolored even though it may not be stained.



Some specific types of medication such as antihistamines and iron tablets can lead to the creation of tooth stains. Also, pregnant women who take tetracycline drugs are in greater danger of permanent tooth stains resulting directly from the drug.



Dental fluorosis refers to the staining of teeth due to exposure to excessive amounts of fluoride. Fluorosis can occur because of consuming water high in fluoride content or overusing toothpaste with a lot of fluorides.



Smoking is one of the most widespread causes of teeth discoloration despite the fact that it can be avoided easily.



Chewing tobacco, in any of its many forms, over an extended period of time can easily lead to teeth discoloration. In India, a massive number of people who have colored teeth is a clear testimony to this fact given the fact that the chewing of tobacco is very popular in the country.

Teeth Grinding

Grinding the teeth against each other over a considerable length of time cause abrasion at the teeth edges. These abraded edges usually appear yellow in color and make the entire tooth look like it has been discolored.

This is more common in children than in adults as a cause of teeth discoloration. Trauma on a child’s tooth causes bleeding, inside the tooth and cracks, both of which may eventually be manifested as black stains that appear on the surface of the tooth.

Enamel hypoplasia; this is a condition that is usually caused by any of some systemic diseases. In this condition, the tooth enamel takes on a chalky appearance. Some of the diseases that can cause enamel hypoplasia include alkaptonuria and rickets.​

While in the past teeth discoloration was considered permanent and irreversible, today many innovative teeth whitening solutions can totally remove the discoloration and leave you with a nice set of sparkling white teeth.
