Root canal treatments can be avoided by timely visits to your dentist atleast once in two years. Early decaying of teeth often go unnoticed as there is no symptom . Most of them ignore these early stages and then visit once there is pain and end up in root canal treatment . Root canal treatment is done usually when more than fifty percent of tooth structure is damaged which eventually leads to pain as the infection has entered the pulp of the tooth. kindly do not neglect dental health as it may prove costlier later. kindly contact dentist near you or visit us for a consultation at Lakshmi dental care , Porur
