About a year back, I had a root canal on the tooth on the bottom jaw, the tooth right of the wisdom tooth on the far left. This had a temporary filling in place and never got filled and replaced due to lack of funds. This temporary filling is on the verge of breaking a year later, and I was wondering what sort of side effect might happen if the temporary filling breaks and the hole in my gums are exposed? I am worried that,due to my extremely poor dental health care, this could become a major problem,as most of my back teeth are chipped,replaced, and/or totally destroyed down to the base of the tooth. Most of my frontal teeth are fine, so I wouldn't see them as a direct problem. Any advice on how to preserve the temporary filling another month while I wait for insurance?
