What causes root caries?
It is caused by bacteria, like all other forms of tooth decay. Poor dental hygiene leads to buildup of bacteria that cause plaque. Also, gum recession, which exposes the tooth root, is another contributing cause. The root is made of dentin, which is much more sensitive than enamel, and which decays much easier. Root decay can also result from changes in the amount of saliva in your mouth because saliva contains many chemicals that keep your teeth and mouth healthy. Many medications, chemotherapy, radiation treatments, and some diseases can cause your glands not to make enough saliva and therefore make cavities and other mouth problems more likely to occur.
