Tooth Sensitivity After Filling? - Patient Question

Transient tooth sensitivity after filling is fairly common, tooth pain weeks after filling is not a common occurrence. This video addresses the possible reasons for tooth sensitivity months after the filling is done. Biological reasons such as the depth of the cavity, closeness to the nerve and plaque contamination. Physical reason has to do with the micro movement of the remaining tooth structure wall, affected by the microscopic hairline fracture, shrinkage of the composite or white filling material known as polymerization shrinkage, sleep apnea, C-factor, void in the filling material, uncured composite and micro gap.
If the tooth is still sensitive after one or two bite adjustments. than the bite may not be the problem. the filling may need to be replace.
If the pain persists for more than 90 days, then the tooth may need Root Canal Therapy.
