Tooth Luxation- A Form of Dental Emergency

Precisely, tooth luxation is the dislodgement of tooth that takes place almost invisibly. The normal position of the tooth in its alveolus is disrupted. There may be a number of reasons behind this. Most commonly, a trauma leads to disruption of ligaments and tissues that are responsible for holding the tooth. Depending on the direction and force of the impact, the dislodgement or luxation may be of different types.

A tooth luxation could therefore be clearly categorized into one of the following:

Lateral luxation

A fracture of the alveolar bone that is the ridge of the jawbone that holds the teeth creates a displacement known as lateral luxation. In this case, the periodontal ligament gets separated which makes the tooth is immobile. It however appears to be pushed either forward or backward. In such cases your tooth will be disengaged by your emergency dentist from the bony socket and will be re positioned with forceps again. The pulp however needs continual monitoring. If it does not heal, root canal treatment becomes necessary.

Concussion

In this case too, the periodontal ligaments that hold your tooth in place are injured. Here, however, the tooth is neither displaced nor movable. Concussion therefore implies immobility of the injured tooth. The tooth remains usually tender when tapped. although X-rays are necessary, yet, the more important task is to do a pulp sensibility test. A positive test implies that the pulp is still vital, while a negative result signals that the pulp may not heal properly.

No conservative treatments exist that may be administered, but the pulp essentially needs to be monitored for at least a year. There are certain at-home measures that you might adopt:

      • Eat soft foods,
      • Be careful while brushing, and
      • Rinse with a chlorhexidine rinse.

Subluxation

This is another type of injury (depending upon the force and direction of impact again) and is characterized by the following:

      • The tooth is mobile but not displaced.
      • There might be bleeding around the gum line.
      • The tooth is generally sensitive to the touch.
      • X-rays usually do not show any abnormalities.

Extrusive

In an extrusive laxation, the tooth is characterized with

      • An elongated appearance
      • Extreme mobility
      • The bony socket however remains intact.

Treatment usually involves a thorough cleaning of exposed root surfaces, if any, with a saline solution and then gently re positioning the tooth in its socket. The tooth may take several weeks to stabilize. Only in case the pulp becomes necrotic, dead and decayed, a root canal may have to be done.

Intrusive

In an intrusive luxation, the tooth is pushed more into the socket. This leads to a fracture in the alveolar bone. Periodontal ligament spaces are no longer visible in the X-Rays and a pulp test also stands negative. In case a tooth has pushed into the socket more than 7 millimeters, surgery and orthodontic treatments are required.

The essence of a tooth luxation treatment consists of stabilizing the tooth and monitoring the health of the pulp lying inside. Therefore, it is very crucial that you see the dentist immediately after an injury occurs and a dental emergency arises. Preventing tooth injuries are the best thing to do. Hence, wearing a mouth guard especially during sports is highly recommended.
