Four Common Causes Of Yellowing Teeth

Most people want a healthy, white smile. Yet, some people are prevented from achieving this goal due to yellow stains on their teeth. In many cases, this discoloration can be removed, but you first need to determine why it is occurring.

Oral Hygiene

Poor oral hygiene practices are the most common cause of tooth staining. Bacteria naturally found inside your mouth can cause plaque to form and collect on the teeth. When plaque is not removed, tarter can accumulate on the teeth, which will give the teeth a yellowish appearance. The more a person lacks brushing, the thicker the tartar will become. Regular brushing, flossing, and rinsing help remove plaque before it can turn to tartar and cause discoloration. If you are experiencing this issue, it might be time to adjust your habits. 


What a person eats and drinks can also have an influence on the appearance of yellow stains. Highly staining foods and drinks are often the biggest culprit, including red wine, berries, tea, and coffee. However, foods high in sugar, such as candy or soda, can also introduce stains. The best way to avoid this issue is to minimize the consumption of these items whenever you can. However, be sure to brush and rinse your mouth whenever you do consume them.


Certain medications also increase the risk of a person's teeth turning yellow. If a medication you are prescribed has this side effect, your doctor will likely let you know. You should then let your dentist know about the medication. Since you will continue to take the medication to benefit your health, your dentist can help you develop a regimen to help minimize the effect of the medication, such as tooth whitening treatments. 

Lifestyle Factors

Lifestyle factors can also be a reason for tooth discoloration. For example, age is often a common culprit. As you get older, it is normal to lose enamel, but as your enamel wears, the yellow dentin naturally inside your teeth becomes more visible. If you are someone who smokes, this can also contribute to the issue, making your teeth appear brown or yellow. Additionally, for some people, genetics contributes to the color of their teeth. Either way, a dentist can help you counteract the problem.

The above represents just some of the factors that can lead to discoloration. To determine precisely why you are experiencing this issue and to remove these stains, make an appointment with a dentist for your exam.
