DEPARTMENT OF ENDODONTICS, THE DENTAL SPECIALISTS.
WHO IS AN ENDODONTIST?
An Endodontist is a Root Canal Therapy specialist. After 4 years of dental school the Endodontist takes 3 years of intensive speciality training.
The CROWN and the ROOT are the 2 parts of a tooth.
Crown part is visible in the mouth. The roots are surrounded 3 dimensionally by bone, under the gums.
The gums are a protective type of skin which are pink in colour that surrounds the neck of the tooth/ teeth and covers the bone.
Incisors are teeth in front jaw. Canines are adjacent to lateral incisors and Premolars. Molars are back teeth. They usually have two or three roots. Most other teeth have one root.
PARTS OF CROWN:
There are 3 parts of crown. The tooth crown has an outer layer made of a very hard substance called enamel.The inside of the tooth is made of a less hard substance called dentin. Below dentin layer is the 3rd layer called Pulp. In the root portion the pulp narrows to become a small canal called Root Canal. Every root canal ends at a tiny opening at the end of the root called Root End Opening. Usually there is one canal in each root, for example: central incisors have one root and usually they have one root canal, but sometimes some teeth have more than one. For eg: Lower molar teeth have 2 roots but 3 canals will be there.
THE PULP TISSUE:
The pulp tissue is a living tissue present in the pulp chamber and root canals.The pulp tissue contains small arteries, veins, and nerves. The veins and arteries nourish the pulp tissue with blood supply. This blood supply helps in defense against any kind of infection of the pulp tissue. The pulp is not just the nerve. But there are nerves which form a part of this complex living Pulp tissue.
PULP AND JAW INFECTION
Pulp infection occurs because of bacteria. Mouth is full of bacteria because of the food particles and ither products keft out in the mouth. This bacteria invades and destroys the pulp tissue.
This pulp infection Toxins ( poisons) destroy the pulp and leak out of the root end and invade the jawbone. This jaw bone becauss of chronic infection can lead to face, neck, jaw sudden serious painful swelling.
