Overview of CPT Code 21084: Removal of impacted tooth
CPT Code 21084 refers to the surgical removal of an impacted tooth, typically a wisdom tooth, that is unable to fully emerge through the gums. This procedure is often necessary to alleviate pain, prevent infection, and avoid damage to adjacent teeth.
When CPT Code 21084 is Used?
This code is applicable in various clinical scenarios, including:
- Presence of an impacted wisdom tooth causing pain or discomfort.
- Infection or abscess formation around the impacted tooth.
- Cysts or tumors associated with the impacted tooth.
- Impacted teeth causing damage to adjacent teeth or bone.
- Preparation for orthodontic treatment requiring tooth removal.
Symptoms Indicating This Procedure
Patients may report several symptoms that indicate the need for this procedure, including:
- Severe pain in the back of the mouth.
- Swelling and tenderness in the gums.
- Difficulty opening the mouth or chewing.
- Bad breath or an unpleasant taste in the mouth.
- Infection signs such as fever or swollen lymph nodes.
Causes and Risk Factors
Several factors can contribute to the development of impacted teeth, including:
- Genetic predisposition to tooth crowding.
- Jaw size and shape that does not accommodate all teeth.
- Early loss of primary teeth leading to misalignment.
- Poor oral hygiene leading to infections.
- Age, as wisdom teeth typically emerge in late adolescence or early adulthood.
Diagnostic Tests Before Procedure
Before the procedure, several diagnostic tests may be performed to assess the condition of the impacted tooth:
- Panoramic X-rays to visualize the position of the impacted tooth.
- Cone beam computed tomography (CBCT) for detailed imaging.
- Clinical examination to assess gum health and tooth mobility.
- Blood tests if infection is suspected.
Procedure Description
The removal of an impacted tooth typically follows these steps:
- Patient is seated comfortably and given local anesthesia or sedation.
- The area around the impacted tooth is cleaned and sterilized.
- An incision is made in the gum tissue to expose the tooth.
- Bone may be removed if necessary to access the tooth.
- The tooth is carefully extracted, sometimes in pieces if it is severely impacted.
- The site is cleaned, and sutures may be placed to promote healing.
Preparation for the Procedure
Patients should follow these steps to prepare for the procedure:
- Consult with the dentist about medications and allergies.
- Avoid eating or drinking for several hours before the procedure if sedation is planned.
- Arrange for transportation home post-procedure if sedation is used.
- Discuss any concerns or questions with the dental team.
Recovery and Aftercare
Post-procedure recovery typically involves:
- Resting for the first 24 hours after the procedure.
- Applying ice packs to reduce swelling.
- Taking prescribed pain medications as directed.
- Avoiding hard, hot, or spicy foods for several days.
- Maintaining oral hygiene while avoiding the surgical site.
Possible Complications
While generally safe, this procedure may have risks, including:
- Infection at the extraction site.
- Dry socket, a painful condition where the blood clot dislodges.
- Nerve damage leading to numbness or tingling.
- Excessive bleeding.
- Damage to adjacent teeth or structures.
