Management and Treatment

How is a knock-out tooth managed or treated?

Take the following steps immediately to save the tooth:

 

  • Pick up the tooth by the crown (the top part of the tooth) and avoid touching the root.

  • Rinse the tooth gently with saline or milk, but do not scrub or clean it with soap or water.

  • Try to place the tooth back into its socket and hold it in place with gentle pressure. If this is not possible, place the tooth in a container of milk or saliva.

  • Seek emergency dental care as soon as possible. Time is of the essence when it comes to saving a knocked-out tooth.

 

If the tooth cannot be saved, your dentist will discuss options for tooth replacement, such as a dental implant, bridge, or denture.

Outlook and Prognosis

What are the potential complications?

Dental avulsion or a knocked-out tooth can have some complications if left untreated. These may include:

 

  • Infection: If the tooth is not properly cleaned or replanted, an infection can develop, leading to more serious dental issues.

  • Bone and tissue loss: When a tooth is lost, the surrounding bone and tissue can also be damaged or lost, making it difficult to replace the tooth later.

  • Cosmetic concerns: Missing teeth can affect a person’s appearance and self-esteem.

What is the outlook?

The outlook for people with dental avulsion depends on several factors, including:

 

  • the person’s age, 

  • the tooth’s condition, 

  • and how quickly the tooth is treated. 

  • If a person seeks prompt medical attention, the chances of successful reimplantation are higher.
