Tooth Dislocation or Sudden Loss in Dogs

Tooth Luxation or Avulsion in Dogs

Dislocation or sudden loss of a tooth in dogs can be referred to as tooth luxation or avulsion. Tooth luxation occurs when a tooth is displaced from its normal position within the mouth, either vertically (up or down) or laterally (to the side).

In vertical luxation, the tooth may either move upward (intrusion) or downward (extrusion) within its bony socket. Lateral luxation, on the other hand, involves the tipping of the tooth to one side, typically resulting from an injury that has pushed the tooth in that direction. Vertical luxation involves the dislocation of the tooth’s root, while lateral luxation affects the positioning of the tooth tip.

When a tooth is completely torn from its bony socket, it is termed as avulsed, signifying a sudden and complete displacement of the tooth from its original location.


In cases of intrusion, the affected tooth will appear shorter than its normal length. Extrusion, on the other hand, causes the tooth to appear longer than usual and allows for both vertical and horizontal movement when touched. In instances of lateral luxation, the upper part of the tooth is visibly shifted to one side, potentially overlapping a neighboring tooth to some extent. Avulsion of the tooth involves complete displacement from its bony socket, often resulting from a mouth injury or an infection affecting the tooth or nearby area.


Trauma or injury, such as accidents on the roadside, falls, or fights, can lead to tooth dislocation or sudden loss in dogs. Additionally, dogs with chronic tooth infections are at a heightened risk of experiencing these dental issues.


To diagnose tooth dislocation or sudden loss in your dog, you will need to provide a detailed history of your dog’s health, including when symptoms started and any recent incidents such as injuries. Your veterinarian will then perform a thorough physical examination, focusing on your dog’s mouth to assess all teeth. This examination will help determine if the tooth is luxated or avulsed and whether it can be salvaged. The primary diagnostic procedure involves taking radiographic images of the oral cavity. X-ray films will be placed inside the mouth to capture images of the affected teeth. These images will reveal any typical changes, aiding your veterinarian in accurately diagnosing and treating the condition.


Surgery is typically performed to reposition the dislocated tooth back to its normal position using various materials, such as fine wires. Anesthesia is necessary for the surgery to ensure the dog remains pain-free and immobile during the procedure. The veterinarian will consider your dog’s overall health and any underlying conditions, as some animals may be at higher risk for anesthesia complications, making it necessary to assess whether saving the tooth outweighs the risks.

If your dog is deemed a suitable candidate for oral surgery, timing is critical for a successful outcome. The sooner the avulsed tooth is reinserted into its bony socket, the better the chances of recovery. Ideally, the avulsed tooth should be replaced within 30 minutes of being dislodged for optimal results.

In case your dog’s tooth is forcibly removed from its mouth due to trauma or other causes, you can preserve the avulsed tooth in normal saline solution or milk to prevent damage and bring it to your veterinarian along with your dog. Time is of the essence, and immediate action is crucial. Following reinsertion, it typically takes 4-6 weeks for the tooth to fully reattach to the socket.

After the surgical procedure, antibiotics are commonly prescribed to prevent infection, and a mild pain reliever may be administered to ensure your dog’s comfort. After 4-6 weeks, the fixation material will be removed, and X-rays will be taken to confirm proper reintegration of the affected tooth. If the tooth has not properly reattached, it may need to be removed due to fixation failure.

Living and Management

Following surgery, it’s important to avoid feeding your dog hard foods for a few days. Your veterinarian will suggest a temporary soft diet to promote healthy bone reformation and prevent the implanted tooth from shifting during the healing process. Additionally, ensure that your dog refrains from picking up solid objects with its mouth to prevent further trauma to the newly implanted tooth.

Maintaining good oral hygiene is crucial for your dog’s full recovery. Daily rinsing with antiseptic solution is typically recommended to prevent infection and promote healing. Your veterinarian will provide instructions on the proper method of cleaning your dog’s teeth and removing debris, food particles, and other material from between the teeth, including the implanted tooth. Oral rinses designed for dogs may be available to help maintain oral hygiene, but it’s important to use them only under the guidance of your veterinarian.
