Professional dentist never remove a bad tooth without trying to save it - fully or at least partially. To save natural tooth dentists in Iowa carry out variety of operations. One of such operation is the removal of tooth pulp. This procedure is often carried out in the case of diagnosis of such diseases as deep caries and pulpitis, when the removal of the pulp is the only way to save the tooth for its future restoration and renewal of its essential functions. Less often this operation is carried out in case of severe periodontitis. Usually such treatment takes 30 minutes. However, dentist put first only temporary filling and in a week it is replaced by permanent one.
