Smoking is a major risk factor for a variety of oral health problems, including gum disease, tooth decay, and oral cancer. Dentists are trained to identify the signs of smoking, such as stained teeth, gums, and tongue. They can also smell the odor of tobacco on a patient's breath.
It is important for dentists to know if their patients smoke because smoking can affect the treatment plan. For example, smokers may need more frequent cleanings and checkups, and they may be at a higher risk for developing complications from dental procedures. Dentists can also provide their patients with information about the health risks of smoking and help them to quit.
