stop smoking

Smoking is a habit that has numerous negative effects on your overall health, and your oral health is no exception. From staining teeth to causing serious diseases, tobacco products pose major risks to the health of your mouth. This article will highlight the key ways in which smoking impacts your oral health.

How Does Smoking Affect My Oral Health?

Tooth Discoloration

One of the most immediate and noticeable impacts of smoking is tooth discoloration. The nicotine and tar in tobacco can turn your teeth yellow over time, and heavy smokers often end up with brownish teeth.

Bad Breath

Smoking causes chronic bad breath, also known as halitosis. The smoke particles that remain in the throat and lungs give breath a distinctive foul odor. Additionally, this bad habit dries out the mouth, leading to decreased saliva production which can cause bacteria to thrive, contributing to bad breath.

Gum Disease

Smoking significantly increases the risk of developing gum disease, a leading cause of tooth loss. This is because smoking weakens your immune system, making it harder for your body to fight off a gum infection. Once an infection damages the gums, the decreased blood flow caused by smoking makes it harder for your gums to heal.

Oral Cancer

The most severe health risk posed by smoking is oral cancer. According to the Oral Cancer Foundation, about 80% of people with oral cancers are tobacco users. Oral cancer can affect lips, tongue, cheeks, and throat. It’s often aggressive, with a high risk of developing secondary tumors.

Delayed Healing

Smokers tend to heal slower after dental procedures such as tooth extractions, periodontal treatments, or oral surgery. The chemicals in tobacco products disrupt the flow of blood and oxygen to the healing area, which can lead to complications such as dry socket after a tooth extraction.

Decreased Sense of Taste and Smell

Smoking can dull your sense of taste and smell, affecting your ability to enjoy food.


This condition, characterized by white patches inside the mouth, is often caused by the irritation from tobacco products. While leukoplakia is usually not dangerous, it can be a precursor to cancer.

Increased Tartar Build-up

Smokers often produce more dental plaque, which can harden into tartar. This can lead to cavities, tooth decay, and gum disease.

The Good News

The good news is that many of these risks decrease after you quit smoking. Even long-term smokers can significantly reduce their risk of gum disease, tooth loss, and oral cancer when they quit. It’s never too late to stop smoking, and there are many resources available to help you quit.

Regular dental check-ups are particularly important for smokers to catch any potential problems early. Your dentist can also provide resources and strategies to help you quit smoking and protect your oral health.
