Avulsion

Case Report

Patient named Mr.Murugan , of age 32 years reported to the clinic with a lower tooth which fell out.

Nature of the Incident: Mr. Murugan was trying to pull out a piece of metal wire with his teeth and in the process of removing the wire, unfortunately his teeth also came out. Patient immediately washed the teeth and wrapped it in a clean paper and came to the clinic within 20 minutes.

Investigation: Intraoral examination was done and an IOPA x-ray was taken.

Radiograph revealed that the tooth had periodontal loss, meaning bone weakening. The excessive force given to the tooth caused it to come out of the socket.

Treatment: Reinsertion of the fallen tooth and composite wire splinting it with adjacent tooth for anchorage.

Expected Outcome: Because of the bone loss present, long term survival of the tooth is very less. Prognosis is poor. This is an interim treatment until the patient to take decision regarding definitive treatment options. The survival of the tooth is based on the the amount of bone support left and vitality periodontal ligament cells , which holds the teeth.

The chances of the tooth staying in the socket without rejection is depends on the time it spends outside the mouth and the steps taken for the tooth to save it.

What to do in case of knocked out tooth?

STEP 1: Pick the teeth up only by the crown portion (white part) not by the root. If the socket is bleeding, gently bite down on handkerchief to stop the bleeding.

STEP 2: If it fell out during playing and is dirty, gently run it under milk or saline.

STEP 3: Immediately put the tooth in a proper storage media container. Storage media preferred is mentioned descending order – milk, saliva (spitting into a container), saline. Water is a poor storage medium but in case of nothing else, its better than leaving tooth to get dry. If not just keep the tooth inside your mouth.

STEP 4: RUSH TO YOUR DENTIST with the tooth container.

Early treatment can save the tooth and the expense for replacement of the teeth. Time is of the essence. As the time goes on, the possibility of the tooth getting reinserted also goes low. The cells surrounding the tooth slowly dies which won’t support the tooth to stay in the socket. Early reinsertion means the teeth might stick to the bone.

Frequently Asked Questions

An avulsion in medical terms refers to an injury where a body structure, such as a tendon, ligament, or bone fragment, is forcibly torn away from its attachment point. This usually occurs due to sudden trauma, such as a fall, sports injury, or accident. In dental cases, tooth avulsion means a tooth is completely knocked out of its socket. Immediate medical or dental attention is essential to reattach or repair the torn structure and prevent long-term complications.

A sprain occurs when ligaments—the tissues connecting bones—are stretched or torn due to sudden twisting or impact. An avulsion fracture, on the other hand, happens when a tendon or ligament pulls off a small piece of bone from its attachment site. While both result from trauma and cause pain, swelling, and limited movement, avulsion fractures involve bone damage, making them more serious. X-rays help distinguish between the two and guide proper treatment.

An avulsion fracture’s seriousness depends on the size of the bone fragment and its displacement. Minor cases may heal with rest, ice, compression, and elevation, while severe ones might require immobilization or even surgery to reattach the bone. Untreated avulsion fractures can lead to improper bone healing, chronic pain, or joint instability. Early diagnosis through imaging and prompt medical care are essential to ensure full recovery and restore normal movement without long-term complications.
