How Smoking Damages Your Teeth

How Smoking Damages Your Teeth

In 2017, it was found that 14 out of every 100 U.S. adults aged 18 or older smoked. Regardless of knowing the adverse effects of smoking, 16 million Americans live with a smoke-related diseases.

However, many people aren’t aware of the effect it can have on their dental health, sometimes leading to irrevocable damage. If proper care is not taken, it can be detrimental.

We’ve listed some damages smoking can have on your oral health:


Smoking tends to stain the teeth in a short span of time because of the tar and nicotine present in cigarettes.

A cross sectional national study with 6,000 UK participants was conducted. 28% of smokers reported “moderate and severe levels of tooth discoloration” as compared to 15% in non-smokers.

They can either cause yellowish-brown or brownish black spots on the teeth, resulting in noticeable blotchy and irregular patches. Nicotine and tobacco products have particles which are like microscopic pores and can stick to the tooth’s enamel. The constant buildup usually causes the stains.


Tobacco and the smoke end up causing large cavities which lead to weak teeth, sensitivity, decay and eventually tooth loss. Since smoking can weaken the immune system, it also makes it harder to fight gum infection.

Smoking prevents the proper flow of oxygen to the bloodstream which hinders infected gums from healing. This may cause tooth decay.

A research conducted at Case Western Reserve University School concluded that smoking can end up diminishing the ability of the pulp, found inside teeth, to fight diseases. Once the gum tissue is damaged, it causes the gums to recede, leaving both the teeth and roots exposed. Due to the nerve endings being exposed, the sensitivity for hot/cold items increases.


The increased use of tobacco exposes the mouth to carcinogenic chemicals which end up changing the genetic cells of the mouth cavity. That causes abnormal cell growth, leading to oral cancer.  

There is a 50% increase associated with tobacco use and developing cancer in the mouth and lips. Tobacco is used the most in the form of cigarettes and causes 90% of the lung cancer deaths. The cancer can also cause prevent the body from fighting it as it weakens the body’s immune system.


Smoking can cause halitosis—chronic bad breath. This happens due to the inhalation of smoke and the smell of cigarette smoke can linger in the lungs for hours. Ethyl pyrrole and ethyl pyridine are some of the chemicals found which causes the unpleasant smell in the mouth, also referred to as smokers’ breath.
