There are several reasons teeth need to be extracted (removed). Some teeth have to be extracted because they are severely decayed, have advanced periodontal disease, or have broken in a way that cannot be repaired. Other teeth may need removal because they are poorly positioned in the mouth, such as impacted teeth, or in preparation for the placement of braces.
It’s important to note that the removal of a single tooth can lead to problems related to your chewing, jaw joint and shifting teeth, which could have a major impact on your overall oral health. The dentist will discuss the pros and cons before an extraction to avoid complications. He will also provide alternatives to extractions as well as replacement of the extracted tooth.
Before an extraction can take place there must be proper numbing of the area. Often if there is infection within an area, it must be treated with antibiotics for 7 to 10 days before extraction can occur to better ensure adequate numbing of the area. It can be difficult, to near impossible, to numb a tooth that is abscessed.
While the extraction is taking place you will feel a lot of pressure. This is a result of the dentist firmly rocking the tooth in order to widen the socket for removal. The feeling of pressure cannot be eliminated from numbing. The anesthetic works by numbing the nerves stopping the transmission of pain. If you do feel pain at any time during the extraction, you must let the dentist know right away.
Sometimes teeth require sectioning or to be surgically removed. This is a very common procedure and becomes necessary when a tooth is firmly anchored in its socket or the root is curved and the socket cannot expand enough to be easily removed. The dentist simply cuts the tooth into sections and removes each section one at a time. He may also surgically lay back the gums and remove bone from around the tooth to better loosen.
If it appears that an extraction may become complicated or if the patient has a health risk, the dentist may refer you to an Oral Surgeon.
