Compared with children's common crown caries, adult root caries are more lethal and may even lead to tooth loss. Tooth root is soft in texture and low in mineral content, which makes it easier to form dental caries than crown. With the increase of age, the incidence of root caries will gradually increase, and the lesions will gradually increase, making it difficult to repair. Root caries appear on the lateral surface of the tooth root, mostly in the form of a shallow disk, with a large area and shallow depth, which is difficult to repair. Moreover, due to the high content of organic matter in the root, the restoration materials are difficult to adhere firmly, and secondary dental caries are easy to occur after restoration. Moreover, many adults only stay in the understanding of "eating less or not eating sweets" and "dental caries are children's patents", and always think that they are insulated from dental caries. This kind of psychology also makes many people find dental caries when the situation is already very serious, so adults should pay more attention to preventing dental caries.
It is necessary to develop good daily oral hygiene habits, conduct regular oral examinations, regularly use dental floss, toothpicks and other tools to remove dental plaque, use health care toothbrushes, and use correct brushing methods to maintain oral hygiene and stay away from dental caries.
