Teeth are divided into two parts: the crown and the root. Because the tooth root is not protected by enamel, it has poor resistance to tooth decay. If the gums recede and the tooth root surface is exposed, tooth sensitivity or tooth decay may easily occur. During routine periodontal examinations, in addition to checking whether there is periodontal disease, special attention will also be paid to the degree of gum recession, and the condition of the alveolar bone will be evaluated with X-rays, so that we can have a correct and objective assessment and diagnosis.

There are many causes of gum recession throughout the mouth. Ye Liwei said that in addition to the most common periodontal disease, improper brushing methods and toothbrush selection, irregular tooth arrangement, loose dentures, tooth wear caused by grinding, missing teeth, and even smoking or genetics may cause gum recession.

Dr. Ye Liwei took a woman in her thirties as an example. One day when she looked in the mirror, she suddenly discovered that her teeth had become very long, her gums had receded, and the color under her teeth had deepened. She was worried that her teeth would fall out, so she made an appointment for a check-up. Ye Liwei said that during the consultation process, it was found that the patient was suffering from long-term tooth root sensitivity. It was also discovered that in addition to gum recession, there was also the problem of tooth root decay.
 
If resin is directly used to fill cavities, it will fall off easily, make it difficult to maintain oral hygiene, and the appearance will be poor. This case was recommended to be treated with "Root Coverage Surgery". During the surgery, the cavities on the tooth root surface were removed, allowing the healthy root surface and autologous graft tissue to be in close contact with the tooth pulp. Periodontal tissue regeneration gel and water laser were used to assist. After the operation, complete tooth root coverage was successfully achieved, and the aesthetics and root sensitivity problems were simultaneously improved.


The signs of gum recession are usually not obvious and difficult for ordinary people to identify. It is recommended to develop the habit of regular check-ups as the best way to prevent gum recession. Through the assessment of gingival recession by a periodontist, the cause, severity and speed of gingival recession can be identified, high-risk areas can be identified as early as possible, and active treatment can be carried out promptly and where conditions permit, so as to avoid the continued worsening of gingival recession.
