Gum diseases due to tobacco and smoking

The use of smokeless tobacco leads to increase in the thickness of the outer layer of cells in the gums due to a process known as gingival keratosis. Tobacco use, both smoking and smokeless can lead to inflammation of the gums, known as gingivitis. The gums will be swollen, red in color and will bleed while brushing. This can further progress in the form of gingival recession, wherein the gums will recede, exposing the root of the teeth. 

Gum diseases due to tobacco

One of the most frequent manifestations of tobacco use and smoking is infection of the gums leading to a condition known as periodontal diseases. In this condition, the tooth will start to be come loose, the alveolar bone underneath the gums will begin to erode and periodontal pockets will begin to appear. In this condition, the gap between the tooth and gums will deepen, leading to accumulation of food particles and microorganisms within this gap. This will further worsen the infection in the gums and leads to a vicious cycle. If left untreated, this will lead to the loss of teeth among tobacco users.

Changes in the enamel surface

Tobacco use, especially the use of smokeless tobacco leads to flattening of the tooth surface, a process known as attrition of the teeth. This is one of the most commonly observed conditions in elderly individuals who have been chewing tobacco for many years. Smokeless tobacco products contain numerous chemical substances, which decrease the pH of the oral cavity. These chemicals render the pH of the mouth acidic, leading to loss of enamel on the tooth surface by a process known as tooth erosion. 

Effect on oral mucosa

Tobacco use leads to a wide variety of manifestations on the mucosal surface in the oral cavity. It leads to increased keratosis, white patches known as leucoplakia and red patches known as erythroplakia. Some individuals tend to place tobacco in the form of a pouch, usually dipped in snuff. This will lead to alterations in the local area in the mouth and is known as tobacco pouch keratosis or snuff dippers’ keratosis. Smokers’ palate is one of the classical findings in smokers wherein the palate surface will be severely involved. The entire palate will be opaque or greyish white in colour and there will be tiny swollen areas with a small red dot in the centre. There can also be diffuse redness in the area of the palate among smokers. 


Some individuals smoke chutta or dhumti with the fire end of the tobacco product inside the mouth. This is known as reverse smoking, which leads to several changes in the oral cavity, especially in the palatal area. There can be redness, tiny outgrowths with central red dots, patches, and ulcers in the palate. Due to the high temperatures associated with keeping the fire end of chutta inside the oral cavity, the local reactions are similar to a burn injury occurring inside the mouth.
