Also, due to hard chewing, periodontal ligament will be damaged, leading to inflammation, edema and pain around the root. On the other hand, due to the accumulation of calcium and betel nut residue, stones are getting thicker and thicker, which leads to periodontal diseases such as gum damage, redness, suppuration and root exposure, and finally teeth fall off or have to be pulled out.
