What is a Root Canal?
Root Canal is the commonly used term for the main canals whitin the dentin of the tooth. These are part of the natural cavity within a tooth that consists of the dental pulp chamber, the main canals. Root canals are filled with a highly vascularized, loose connective tissue, the dental pulp. This sometimes becomes infected and inflamed, generally due to caries or tooth fractures that allow bacteria from the oral flora or their byproducts, access to the pulp chamber or the root canals, damaged or dead pulp causes increased blood flow and cellular activity, and pressure cannot be relieved from inside the tooth causing pain when biting, chewing or with cold or hot food and drinks.
Because the tooth will not heal by itself, the infection continues to spread, bone around the tooth will begin to degenerate, pain usually worsens until emergency dental attention is required.
1. A local anesthetic is applied to numb the area.
2. A rubber sheet is then placed around the tooth to isolate it.
3. A gap is drilled from the crown into the pulp chamber, which, along with any infected root canal, is cleaned of all diseased pulp and reshaped. Medication may be inserted into the area to fight bacteria.
4. Depending on the condition of the tooth, the crown may then be sealed temporarly to guard against recontamination, or the tooth may be left open to drain, or the dentist may go right ahead and fill the canals.
