Why do traumatized teeth become mobile?

Trauma to the teeth can be transmitted to the supporting structures, which get damaged. This can cause mobility of the teeth. Such mobile teeth may require splinting for a specified period of time till the supporting tissues heal and the tooth becomes stable.

What is splinting?

Splinting is a procedure where the teeth are supported in its position for a period of time. This is done to teeth that are traumatized or teeth whose supporting structures are affected by disease, which prevents them from supporting the teeth. Splinting involves binding a group of teeth together so that the biting forces are shared by a large number of teeth instead of being born by the affected tooth.

Can traumatized teeth get displaced?

Teeth that are traumatized can be displaced from their position. This displacement can be in any direction depending upon the type and direction of trauma. The displacement can be into the bone (i.e. the tooth is driven into the bone) or can be displaced partially out of the socket. Such displaced teeth may have to be repositioned in the socket and splinted for a specified period of time. These teeth may also require endodontic therapy.

Why is a traumatized tooth tender on biting?

A tooth that is subjected to trauma shows injury and inflammation of the underlying supporting tissues. This causes the teeth to be tender and also dislodge slightly out of the bone. These extruded teeth are tender on biting.

Can a fractured piece of tooth be reattached?

Fractured pieces of the crown can be reattached using composite cements. So it is advisable to retain the fractured piece and take it with you when you consult the dentist.

Can injury to teeth cause discoloration?

If the nerve and blood supply to the tooth gets damaged or destroyed the pulp of the tooth dies. The dead pulp can discolor the teeth, which can look brownish to black in colour. Usually the pulp recovers after mild injuries and there is no change in color. However, if the pulp gets damaged then gradually the colour of the tooth changes over a period of time. Endodontic treatment of the teeth can revert back the tooth colour and function. Some tooth may require additional procedures like bleaching of the teeth or whitening of the teeth if discoloration is severe and persistent.

Can a tooth dislodged from its place out of mouth be put back to function normally?

Yes, if the tooth is intact it can be placed back into the socket. However, the outcome of the treatment depends on how quickly the tooth is put back in its place. Prolonged time out of the mouth and drying of the tooth will have poor prognosis. Until a dentist is approached the tooth should be carried in the patient's mouth or externally in a cup of milk or sterile water or normal saline. The tooth should never be allowed to dry. In these emergencies the success of treatment depends on how quickly the tooth is put back inside. So it is advisable to contact your dentist immediately.
