Smoking cigarettes has a significant impact on oral health, and dentists can often tell if a patient is a smoker based on various signs and symptoms in their mouth.
One of the most common signs of smoking is tooth discoloration. The tar and nicotine in cigarettes can stain the teeth, causing them to appear yellow or brown. Smokers are also more likely to have gum disease, which can lead to bleeding, swelling, and pain. In addition, smoking can slow down the healing process of the mouth, making it more difficult to treat dental problems.
