Pulp Diseases

The life or death of a tooth depends on the health of the pulp. This network of nerves, blood vessels, and tissues is housed in a hollow central chamber that extends from the crown of the tooth to its roots. The branch of dentistry that specializes in preventing and treating pulp problems is called en­do­dontics.

The pulp can be damaged in a number of ways. One of the most common is through undetected tooth de­­cay. Advanced periodontal disease can also infect the pulp. Pulp damage also occurs when a tooth is broken or knocked out. Abrasion and erosion can wear away the tooth’s hard outer layers, leaving the pulp vulnerable. Finally, the pulp may be in­jured when your dentist grinds a tooth in preparation for a

deep filling or restoration.
Pulp damage can be as either reversible or irreversible. It can range from mild tooth sensitivity to complete nerve death of the tooth to infection of the surrounding tissues.

There are several different pulp diseases, including:

Reversible pulpitis, or mild inflammation of the pulp. Symptoms typically include pain upon eating or drinking something very sweet, hot, or cold. Without treatment, the inflammation can progress to a dental abscess, a collection of bacteria and pus. Good oral health habits can help offset reversible pulpitis, but in many cases, a filling is eventually needed.

Irreversible pulpitis, or severe inflammation of the pulp that can't be cured. Symptoms include sudden intense pain. Left untreated, it can result in a widespread gum and connective tissue infection. Irreversible pulpitis is generally treated with a root canal procedure. If that doesn't work, your dentist may have to remove the tooth.

Dental pulp calcification (also known as dental pulp stones). This is a condition in which hardening, or calcification, of pulp tissue results in hypersensitivity and extreme pain because the dental nerves become compressed. A root canal is usually necessary to clear away hardened tissue.

Dental pulp exposure. This condition comes on when damage to the external covering of a tooth, such as a cavity or crack in the tooth, exposes the normally protected pulp to bacteria and irritating food particles.

Pain is the most frequent symptom and without proper dental care, a mild infection can progress into a serious abscess.

Depending on the type of pulp disease, symptoms may vary in intensity and can include:

· Pain in a tooth or teeth when you eat something very sweet, hot, or cold;

· Sudden, intense pain in the mouth;

· Infection in the mouth.

If pulp diseases aren't properly managed, you can lose your teeth.
