Quitting Smoking

I’ve been trying to help a couple patients quit smoking lately and so this topic is on my mind. By now it’s no secret that smoking is horrible for pretty much any aspect of your health. It is currently the number one cause of preventable disease and mortality in the United States, with 480,000 deaths occurring each year from tobacco use. While some statistics show the problem to be getting better, the CDC still paints a grim picture in my opinion; in 2014 they said that 16 million people live with a smoking related illness and that almost 17% of adults 18 and over are smokers—a count of almost 40 million adults in this country alone!

Smoking Causes Cancer

It is well documented how the chemicals in cigarettes affect cells of the mouth and lungs. Constant bombardment from toxins causes cells to react defensively and alters their DNA expression. Eventually, the practice becomes a game of Russian roulette where something in the genetic coding is bound to go wrong the more times cells are exposed to toxins. If that weren’t bad enough, smoking also impairs the body’s immune system and prevents cells from properly cleaning up the toxins that eventually cause cancer. Perhaps worst of all, most people that smoke are quite aware that it is terrible for their health, but because smoking causes both a chemical and a behavioral dependency, they are unable to break the habit on their own terms.

Smoking Causes Dental Problems

In a relatively new area of smoking research, scientists are now showing that smoking has a profound effect on bacterial populations in the mouth. Researchers from NYU Langone Medical Center and Isaac Permutter Cancer Center have been studying this topic and published some interesting findings. Their results show that the mouths of smokers are dramatically different from the mouths of non-smokers. Smokers’ mouths have very high levels of 150 different bacterial species that are normally very low in the mouths of non-smokers—some of which being bacteria that are detrimental to oral health—and very low levels of 70 other species that are much higher in the mouths of non-smokers—mostly toxin-cleaning proteobacteria. For example, cavities are caused by bacteria in the Streptococcus family; smokers have 10% higher counts of Strep bacteria, which, in part, explains why smokers are much more predisposed to having tooth decay.

Quitting Changes Things Completely!

As bad as smoking is, there is great news for those who quit. In most cases, the body is amazing at repairing itself and bringing things back in balance. The research team mentioned above documented that upon quitting, oral bacteria return to their normal levels and after 10 years of being cigarette free, bacterial populations are indistinguishable from the mouth of a non-smoker. Plenty of research suggests the same thing occurs on a systemic level; the effects of quitting are not only very positive, but they also happen quickly and dramatically.

If you are struggling with a tobacco habit, I urge you to keep up the fight. Most smokers go through more than seven honest attempts before quitting successfully, so don’t give up! If you need assistance, check out the following good resources available to people in Utah:

About the author

I can't wait to meet you! I'm Dr. Nick Young and I've been here at Canyon Gate Dental since 2010. I initially joined Dr. Payne as an associate dentist and was so impressed with this great office and amazing patient family that I wanted join the team for good. I became an official partner of the practice at the end of 2012 and I love my job. As a general dentist, I enjoy all specialties of dentistry, but I like emergency dentistry in particular. It's so satisfying to help people look and feel great and also help them get out of pain. I'm from Provo and attended Brigham Young University for my undergraduate degree and the University of Louisville for dental school. I've been married for 9 years to my beautiful wife, Heather, and we have two young children. My favorite thing to do is be a daddy and rough house with my kids, but I also enjoy playing golf, watching football and basketball (Go Cougs!), and going on dates with my wife.
