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.

Gum Disease and Diabetes

Periodontitis and diabetes are both chronic diseases that modulate each other. That is, they can exacerbate each other, each making the other more severe. Diabetes can have a negative effect on periodontal health and periodontal disease can increase the need for insulin in diabetics.

Periodontal Disease Has a Negative Effect on Diabetic Control

Periodontal disease is an infection that, like any infection, can make it hard to keep blood sugar under control. Increased blood sugar levels can result in an increased risk for diabetic complications such as harm to the eyes, nerves, kidneys, and other important organs. But studies have shown that treatment of periodontal disease can reduce the need for insulin in diabetics. So, by treating and controlling the periodontal infection, a person also is controlling insulin need and diabetes.

Poor Diabetic Control Has a Negative Effect on Periodontal Health

Compared to non-diabetics, people with poorly-controlled diabetes (those with blood glucose levels above normal) are more likely to develop periodontal abscesses and other oral infections. The longer someone has diabetes, the more likely they are to have periodontal disease. And if the person smokes and has poorly-controlled diabetes, the risk of developing periodontal disease is even greater.

Poor diabetic control can affect the gum tissue in two ways. One is the result of the thickening of the blood vessels that occurs with diabetes. This results in a reduction of oxygen and nutrient delivery to the tissues and a diminished ability of the immune system to fight infection, including periodontal disease. The second is because many of the bacteria that cause oral infection thrive on the sugar linked to diabetes (glucose). Poor diabetic control can actually feed the bacteria that cause periodontal disease.

Oral symptoms associated with poor diabetic control include:

• Increased tooth mobility
• Dry mouth that can increase the risk for ulcers, root cavities, and infections
• Infections that take longer to heal and are more severe

These symptoms can all be managed with control of blood glucose and improved periodontal health. If the diabetes is well controlled and blood sugar level is within the normal range, the risk of developing periodontal disease is not greater than in people who don't have diabetes. On the flip side, treating periodontal disease reduces the need for insulin on people that have diabetes.

To prevent complications from periodontal disease and diabetes, it is important to maintain normal blood sugar levels and periodontal health. Follow the diet and medication guidelines supplied by your physician and see your dental care provider routinely for periodontal screenings and professional cleanings. Meticulous plaque control is critical. If you have diabetes, your dentist needs to know what your blood glucose level is before starting any dental surgical procedures, and although abscesses and acute dental infections should be treated as soon as possible, non-emergency dental treatment should be postponed until the blood glucose is well controlled.
