When I went to see the dentist they said that from over brushing I have worn the gum on one tooth and so it has receded leaving some of the tooth root on show.
They have advised to have a composite filling to cover the part of the root that showing to stop sensitivity and to protect the root.
I have not really heard of this being done before so wondered if anyone else has had this done and can there be any negatives to doing it rather than leaving?
