It’s no secret that smoking is bad for your overall health but using tobacco products can have serious consequences on your oral health, too.

In addition to affecting your overall health, tobacco use and smoking can cause a number of oral health issues, ranging from oral cancer to discolored teeth.
“You can get yellow teeth [and] a yellow tongue,” says Thomas Kilgore, DMD, professor of oral and maxillofacial surgery and associate dean at the Boston University Henry M. Goldman School of Dental Medicine. “You see a lot of staining on the tongue.”
Smoking and tobacco use can lead to more serious oral health complications as well, including gum disease and oral cancer.
Smoking and Oral Cancer
“The most serious issue is mouth cancer,” Dr. Kilgore says. “It’s hard to say what percentage of people who smoke will get mouth cancer, but the death rate of those who do get it is high — between 40 and 50 percent of all cases, and that hasn’t changed over the last few decades.”
The American Cancer Society estimates that 90 percent of people with oral cancer (cancer affecting the lips, tongue, throat, and mouth) have used tobacco in some form. Likewise, the risk of oral cancer is six times higher among smokers relative to non-smokers. Your individual risk of oral cancer depends on how long you’ve been using tobacco — the longer you use it, the greater your risk.
Smoking and Periodontal Disease
“Smoking cigarettes doesn’t cause dental decay, but it does cause periodontal, or gum, disease,” Kilgore explains. “Bone loss is part of periodontal disease. It starts out as inflammation of the gums. In the natural and unfortunate progression, the bone supporting the roots of your teeth becomes inflamed,” and then the underlying bone can deteriorate, he adds.
“There are surgical and nonsurgical therapies to reverse or slow the progression of periodontal disease,” Kilgore says, but without proper treatment, gum disease does eventually lead to tooth loss and jawbone damage. One study found that smoking was associated with more than 50 percent of periodontal disease cases.
For Oral Health, No Tobacco Is Safe
People often think that different forms of tobacco are “safer” than others. However, says Kilgore, “Tobacco in any form has risks. It’s hard to figure out which is worse” — when tobacco is chewed, smoked, or inhaled.
The bottom line is that regular exposure to tobacco in any form can compromise your health. Kilgore points out that “pipe smokers may not smoke very often, but they can [still] get cancer of the lips, as they’re always holding the pipe in the same place on the lip.” Additionally, “there’s a myth that chewing tobacco has less risk, but it’s been shown pretty clearly that this isn’t true.”
