If missing teeth are not filled, it is easy to become demented

People with less than 20 natural teeth and no dentures or implants have significantly poorer chewing ability

Is it okay to lose teeth when you get old? Recently, a Japanese study found that the risk of elderly people who lose teeth but do not repair them in time is 1.9 times that of the general elderly people who suffer from cognitive impairment.

A four-year observation of 4,425 people aged 65 and above found that those with less than 20 natural teeth and no dentures or implants had significantly poorer chewing ability, and the proportion of those suffering from cognitive impairment was 1.9 times that of those with normal chewing function. The chewing ability of people with more than 20 natural teeth in their mouth is similar to that of people with less than 19 teeth but wearing dentures.

Chewing each mouthful of food 30 times and sticking to it can help prevent cognitive impairment

Huang Mingyu, executive director of the Taipei Dental Association, said that just the movements of opening and closing the mouth and clicking the teeth can simultaneously exercise the facial nerves and muscles, temporomandibular joints, etc. Chewing each mouthful of food 30 times and persisting in doing so will help prevent cognitive impairment.
