Endodontics is a specialized type of dentistry that deals with abnormal tooth pulp; the causes/origins, diagnosis, prevention and treatment of diseases and injuries to the pulp; and other conditions affecting the tissues surrounding the pulp and canal (channel inside the tooth root). Tooth pulp, the soft tissue that contains nerves, blood vessels and connective tissues, runs through the hard tissue inside the tooth (dentin) and extends from the crown (top) of the tooth down to the tip of the root in the jaw bone.

Depending on your situation, your dentist or endodontist may perform any one or combination of procedures to treat your condition. The cost for endodontic therapy typically averages $600 to $900. The cost for a therapeutic pulpotomy (excluding final restoration) is approximately $150, and the cost for apicoectomy/periradicular surgery ranges from $550 to $700.
Signs and Symptoms of Endodontic(endodontic motor) Problems.

You may need endodontic treatment if you experience the following:

Significant tooth discomfort or pain
Prolonged tooth sensitivity to hot and cold
Gum tenderness to the touch and when chewing
Swelling
Tooth discoloration
Drainage and tenderness in the lymph nodes, jaw bone and gingival tissues

If a root canal procedure is not performed, an abscess (infected pus pocket) can form at the tip of the tooth root that can be painful. Even if there is no pain, the bone holding the tooth in the jaw can be damaged.
When is Endodontic Treatment Appropriate?

Endodontic treatment is necessary when the dental pulp(pulp tester) becomes inflamed or infected as a result of deep tooth decay, repeated dental procedures on the tooth or a crack, chip or other injury to the tooth. Most teeth can be saved by endodontic treatment.

The endodontist removes the inflamed/infected pulp, cleans and shapes the inside of the canal and fills and seals the space. Afterwards, the endodontist usually will refer you back to your dentist for placement of a crown or other restoration on the tooth to protect it. The restored tooth will have a natural appearance and continue to function like other healthy teeth. With proper oral care, it may last a lifetime.
