Smoking and Gum Disease
The systemic risks of tobacco use are well known. Tobacco use can increase the risk for cancer, lung disease, and heart disease. But whether you smoke, dip, or chew tobacco, it also affects the oral cavity in a variety of ways. It contributes to oral cancer, stains the teeth, and contributes to tartar deposits, bad breath, and a loss of taste and smell.
Tobacco use causes inflammation of the soft tissues of the mouth, ulcers, recession, and other oral lesions. Tobacco users are two times more likely to develop periodontitis, and ten times more likely to develop acute necrotizing ulcerative gingivitis (ANUG). They also are more likely to lose teeth than those who don't smoke. Smoking is the number one most significant risk factor in the development and progression of periodontal disease.
Tobacco smoking causes periodontal bone loss that is not related to the amount of gum inflammation or plaque accumulation. Although the periodontal disease may be advanced, the classical signs of gum inflammation (redness, bleeding gums, etc.) are not usually as evident in tobacco smokers. Thus, prevention and early detection are more difficult.
Tobacco smoking has a direct effect on the oral tissues and it can alter the immune response. Although smokers do benefit from periodontal treatment, the healing is often delayed and the results are less predictable. In addition, the success rates of periodontal and implant treatment are reduced in people who use tobacco products. The amount of complications is related to the amount of daily tobacco exposure, and the number of years the person has been exposed.
The use of tobacco products can increase the risk of periodontal disease:
1. It weakens the immune system: Tobacco products suppress the body's ability to fight infection. Carbon monoxide (a major byproduct of cigarette smoke) reduces oxygen concentration and inhibits the movement of white blood cells. This reduces the capacity of the white blood cells to fight bacteria (including the bacteria that cause periodontal disease), and delays healing.
2. It masks signs of infection: Tobacco reduces the ability of blood vessels to carry infection fighting cells, nutrients, and oxygen to the tissues. As a result, the typical signs of periodontal disease (redness, swelling, and bleeding of the gums) are masked. People who smoke may have periodontal disease that is harder to diagnose.
3. It increases calculus formation: Smoking can cause more calculus (tartar) accumulation that if not removed promptly can lead to more plaque build-up and periodontal disease.
4. It reduces healing: Nicotine and other chemicals can be absorbed directly by the root surfaces of the teeth and reduce the ability of cells to reattach to the root surface during healing.
Besides the obvious health benefits of discontinuing tobacco use, quitting can also reduce the risk of oral cancer and the detrimental effects of tobacco on the gums and bone that support the teeth. In addition, another incentive to stop smoking is that former smokers respond similarly to never smokers to periodontal treatment.
Because there is a physical and psychological addiction to tobacco, quitting can be very difficult. But millions of Americans quit smoking every year. There are aids available that reduce the craving for tobacco. These include the use of systemic medications, the nicotine patch, the nicotine gum, the nicotine inhaler, and the nasal spray. See your dentist or physician for aid in stopping tobacco use.

Periodontics: Uses of Periodontic Dental Lasers
Since their introduction in the 1960's, laser use in medicine and dentistry has increased steadily, and it's been no different in Periodontics. The CO2 and the Nd:YAG lasers have both received Food and Drug Administration (FDA) approval for soft tissue surgery and are the most commonly used lasers in dentistry. A dental laser work by delivering concentrated beams of light strong enough to cut through tissue.
Pros & Cons of Dental Lasers
The popularity of lasers results from claims that dental laser gum treatment is painless. Although the FDA has not permitted the manufacturer of any laser to make that claim, the general experience described by patients is that there is less pain and swelling after laser treatment compared to conventional oral surgery. Local anesthesia for pain control is still required during laser surgery.
Another advantage of the laser is that it causes less bleeding in the area of surgery than traditional oral surgery techniques. This is especially helpful in the oral cavity, which has an abundant blood supply. The laser decreases bleeding by sealing the blood vessels at the surgical wound. On the flip side, this can delay healing and create a less stable wound.
Application of Lasers in Periodontal Treatment
The application of lasers in periodontal treatment is restricted to the removal of gum tissue to reduce pocket depth, or for some minor periodontal plastic surgery procedures. These surgeries can be easily performed with traditional instruments without the additional high cost of dental laser treatment.
More recently, lasers have been evaluated for use in scaling and root planing. But in a research study recently published in the Journal of Periodontology, laser therapy appeared to be less effective than traditional scaling and root planing treatment. In fact, research has not conclusively shown that laser therapy is effective in removing the tartar that has accumulated under the gum line and can actually damage the surfaces of teeth and the bone. This damage could delay healing and the ability of the gum tissue to reattach to the root surface.
For all these reasons, the American Academy of Periodontology is concerned about misleading claims regarding the use of lasers in periodontics. It is important to remember that laser treatment in periodontics is limited to soft tissue (gum) for periodontal surgery and that the laser beam should not touch the tooth or bone. Anesthesia is required during dental laser treatment, and dental laser treatment may be more expensive than traditional surgical procedures.
