Avulsion of Tooth: Emergency Steps to Save Your Knocked-Out Tooth

A knocked-out tooth (avulsion) is a time-sensitive dental emergency. The most critical step is to see a dentist within 30 to 60 minutes. While the nerves and blood vessels within the tooth cannot be repaired, the surrounding bone can often reattach to the root if the tooth is replanted quickly and handled correctly.

Immediate Steps to Save Your Tooth

If a permanent tooth is knocked out, follow these guidelines to improve the chances of successful re-implantation:

• Handle by the crown only: Never touch the root. The root surface contains delicate cells necessary for healing that are easily damaged.
• Rinse if dirty: Use water to gently rinse away debris. Do not scrub, dry, or wrap the tooth in cloth.
• Attempt re-implantation: If possible, gently place the tooth back into the socket, ensuring it is facing the correct direction. Do not force it.
• Keep it moist: If you cannot reinsert the tooth, keep it moist at all times. Use milk, an emergency tooth preservation kit, or hold it inside your cheek. Avoid storing it in tap water, as it can harm root cells.
• Seek immediate care: Contact an emergency dentist or endodontist immediately.

What to Expect at the Dentist

Treatment depends on the severity of the injury and how long the tooth was out of the mouth. The dentist will clean the socket and gently reposition the tooth. To stabilize it, a splint made of soft wire or composite material will be attached to the neighboring teeth. This splint typically stays in place for several days to weeks. Because the internal nerves and blood vessels are usually damaged during an avulsion, a root canal is generally required for permanent teeth.

Healing and Follow-Up

Healing time varies based on the extent of the injury. If the tooth was not fractured, the root may reattach to the bone within three to four weeks; more severe injuries may require six to eight weeks. Your dentist will schedule follow-up appointments over the next two to three years to ensure the tooth remains healthy and successfully re-implanted.

Frequently Asked Questions

How long can a tooth be out of the mouth?

While the best outcomes occur within 30 minutes, a tooth can often still be saved if it is replanted within one hour of the accident.

Is a root canal always necessary?

Yes, because the nerves and blood vessels are severed during an avulsion, they cannot be repaired, making a root canal necessary to prevent infection.

What if the tooth is broken?

Re-implantation is more complex if the tooth is fractured. Seek professional care immediately, as the dentist will need to assess the structural integrity of the remaining tooth.

Should I try to put a baby tooth back in?

No. You should not attempt to re-implant primary (baby) teeth, as this can damage the developing permanent tooth underneath. Contact your dentist for guidance.
