Toothache - Tooth Root Sensitivities

Tooth Root Sensitivities

Chronic gum disease also contributes to toothache due to root sensitivities. The roots are the lower 2/3 of the teeth that are normally buried in bone. The bacterial toxins dissolve the bone around the roots and cause the gum and the bone to recede, exposing the roots. The exposed roots can become sensitive to cold, hot, and sour foods because they are no longer protected by healthy gum and bone. The sensitivities may be so severe that the patient avoids any cold or sour foods.
