What are the effects on human health:

1. Because lime and betel nut juice fill the mouth, dental calculus is formed, and due to long-term hard chewing, the dentin is chewed, and even the teeth are damaged. Cracked or broken.

2. Impact on the temporomandibular joint: Due to dentin consumption and temporomandibular joint surface wear, occlusion changes and temporomandibular joint pain and lesions will cause sound and joint pain when opening and closing the mouth.

Also, chewing hard will cause damage to the teeth. The peritoneal membrane causes damage, causing inflammation, swelling, and pain around the tooth root. On the other hand, due to the accumulation of lime and betel nut residues, the calculus becomes thicker and thicker, causing gum damage, redness, swelling, suppuration, and exposure of tooth roots, etc., resulting in periodontal disease, and eventually the teeth fall out one by one or have to be extracted.
