Don’t ignore pain
Over 50% of the brain that deals with sensation covers the head alone, with the rest of the body being covered by the rest. This is why pain in the mouth and face affects us more than any other part of the body.
Ignoring long standing pain can lead to permanent tissue damage which, in turn, can lead to permanent nerve damage. Such nerve damage can mean the pain continues even after the cause of the pain, such as a decayed tooth, has been removed.
If you start getting pain, get it treated early, the solutions are usually simpler and cheaper the earlier it is treated.
