Tooth retention is a phenomenon that is quite common in dental practice. Due to various circumstances (early removal of milk teeth or incorrect position of nearby teeth), the tooth may not have enough space on the jaw for full eruption, and then it remains in the bone or covered with a mucous membrane. Usually these are wisdom teeth. An accurate diagnosis is established by X-ray examination.
When an impacted tooth becomes the cause of inflammation, the question arises of its removal.
Indications for the removal of an impacted tooth are divided into:
- Absolute – when a tooth causes the development of purulent periostitis, osteomyelitis, phlegmon – to prevent the spread of a purulent infection.
- Relative – pulpitis, periodontitis of the tooth develops, but there is no immediate threat to the patient's life.
Contraindications are also divided into absolute (severe condition of the patient) and relative (comorbidities).
Removal takes place under local anesthesia (infiltration – on the upper jaw and conduction – on the lower). Sometimes, according to indications, under general anesthesia.
With a scalpel, the mucous membrane covering the tooth or bone tissue above it is dissected. The maximum access to the operation area is achieved.
The bone tissue is cut with the help of a bur, which makes it difficult to access the tooth.
The tooth is extracted by the elevator. Sometimes, if the tooth is massive, it is first sawn into several parts and only then removed. The operation to remove an impacted tooth takes from one to three hours.
A drug (for example, iodoform turunda) is placed in the hole, then the patient comes for dressings. Or, if necessary, the hole is sutured.
Postoperative complications in the form of soft tissue edema in the area of the extracted tooth, difficulties in opening the mouth in this case are very possible. According to indications, antibacterial, antihistamine, painkillers are prescribed. The recovery period may take approximately a week. Wound healing is controlled by a dental surgeon.
