According to Medical News Today (MNT) receding gums are also known as gingival recession. The pink gum tissue normally covers the root of the tooth. This can become exposed when the gum is pushed back or if the tooth is in an abnormal position.
Receding gums are common and often unnoticed at an early stage. There are many risk factors, but age is a main one 88 percent of people older than 65 have receding gums in at least one tooth.
The main concern with receding gums is that when the roots of the teeth become exposed, they are at risk for decay, infection, and loss. Treatment can stop or reverse the process of gum recession if begun at an early stage.
If the recession is severe and the patient has symptoms such as tooth sensitivity, pain, or infection, a variety of treatment options are available. These include deep cleaning, medicine to fight infections, and even tissue grafts.
