I have two front incisor teeth with bone loss in between down nearly to the root. what should i do?

Depends: It depends on how much bone loss there is. If it is major the teeth may have to be removed. A periodontist could give you the best idea of what your options are. They specialize in treating gum problems.

Why: The first thing, i would think, is to find out why so other teeth don't develop the same type of problem. Ask a dentist what to do since more information is needed, like x-rays, to properly treatment plan your situation.

Correct occlusion: Evaluating for fremitus, a condition where upon biting on the back teeth, the front tooth experience an interference and a jiggling force produced. A resulting small gap may lead to food impaction, gingival inflammation, and further exacerbate the bone loss. Correct the interference and bone will grow back by itself or grafting may required. Treatment is easy if there is good posterior occlusion.

Gum Specialist: Sometimes that bone can be regenerated and in some cases it cannot. A periodontist could tell you.
