Oral health is closely related to overall health. Is it normal for people to lose their teeth due to aging? Don't worry if your teeth don't hurt? Don't you need to wash and clean your teeth when you're old? Several dental experts have reminded us that there are still many misconceptions in elderly dental care, as evidenced by the common oral problems among the elderly. Is it normal for people to lose their teeth due to aging? Is it normal for people with periodontitis to have old teeth? To find the real culprit behind it! Nowadays, many elderly people in their 60s have less than 20 teeth left, and the 'real culprit behind them' is mostly due to periodontitis. "Yu Lina, deputy chief physician of the Affiliated Stomatological Hospital of Guangzhou Medical University, said that many people do not attach importance to periodontitis, and as a result, periodontitis continues to develop, teeth begin to loosen, and many teeth roots are exposed, making it easy for oral damage such as decay and caries to occur. In addition, many elderly people do not brush dentures in a standardized manner after wearing them, which accumulates a lot of bacteria and fungi on the dentures. It is also easy to develop mucosal diseases such as mouth corner peeling and oral fungal infections. Yu Lina reminds that teeth loss caused by periodontitis should be repaired in a timely manner, and after repair, attention should be paid to standardized cleaning. Don't worry if your teeth don't hurt? Small problems have a big impact. "During free clinics, it was found that many elderly people tend to take missing teeth lightly." On September 16th, during the 35th "National Teeth Love Day" on-site promotion event in Guangzhou, Zhi Qinghui, deputy chief physician of Sun Yat sen University Affiliated Stomatological Hospital, stated that people often attach great importance to the pain in front of them and tend to overlook or delay some oral problems that appear to be "small problems" but actually have long-term effects. In addition to periodontal disease, wedge shaped damage and low quality restorations have also been found during the free clinic. Some elderly people have severe tooth loss, but the quality of restorations for both movable teeth and fixed bridges is not very high. Many elderly people's fixed bridges have deformed due to too long time. "Zhi Qinghui said that many elderly people do not value their oral health and feel that they can use them. They wait until they have toothache or loose teeth before seeking medical attention, This is one of the common misconceptions of tooth protection among elderly people. Dental problems such as dental calculus, gingival recession, and decayed roots are often overlooked, but these are actually important pathogenic factors for the development of periodontal disease. People don't need to clean their teeth anymore? Elderly patients with chronic diseases should pay more attention to the impact of some chronic diseases on dental health, while elderly people may procrastinate due to a lack of corresponding knowledge. "Diabetes patients should go to do periodontal health care regularly." Que Guoying, chief physician of the Dental Hospital of Southern Medical University, reminded that diabetes and periodontitis affect each other. Some diabetes patients will have recurrent periodontal abscesses, which will affect the treatment of diabetes. And if periodontitis is well controlled, it can also help to control blood sugar. In addition, cracked teeth are an oral problem that is easily overlooked by the elderly population. Zhi Qinghui said that during the half day free clinic that day, he saw two cases of cracked teeth. Many cases of cracked teeth are caused by accidents. Elderly people should be careful not to bite particularly hard objects in their daily lives, such as chicken bones and pig bones. "Zhi Qinghui reminded that some elderly people may have missing teeth or swollen gums, but they are unaware of it. Therefore, they need to undergo regular oral cavity examinations and develop the habit of regularly checking and cleaning their teeth. Regular dental cleaning can remove soft tartar and dental stones from the periodontium, reducing the probability of periodontitis. Pay attention to a balanced diet in daily life,
