Harm of chewing betel nut

First, damage to oral mucosa

Under normal circumstances, our oral mucosa is bright, ruddy, shiny, soft and elastic, but if we chew betel nut for a long time, the oral mucosa will shrink, and the fibrous tissue will degenerate and proliferate, losing its original luster and elasticity, becoming hard and not smooth at all.

Second, the mouth is getting smaller and smaller.

Due to the atrophy of oral mucosa, the mouth will also shrink, and the mouth will not open, and it will be small and round, and it will be difficult to speak clearly and eat. Moreover, the atrophy of the oral mucosa and the shrinkage of the mouth, the decrease of saliva secretion, dry lips, broken corners of the mouth, often oozing blood, so the mouth is mottled.

Third, the face will get bigger and bigger.

Although chewing betel nut for a long time will make your mouth smaller and smaller, your face may get bigger and bigger. This is because the fiber of betel nut is very thick and it is difficult to chew. Under the stimulation of chewing, the muscles and bones in the patient's jaw angle area develop, so that the patient's chewing muscles will become developed. On the other hand, the teeth will be shortened and the face will be very wide.
