The Knocked Out (Avulsed) Tooth

The Knocked Out (Avulsed) Tooth

Knocking out a tooth, otherwise known as avulsion, can be a scary thing! Avulsion accounts for 0.3-5% of all dental injuries. This is one of the most serious dental injuries and many studies have shown that the first few minutes following the accident are key.

Timing is everything!

In most situations involving permanent teeth, the best treatment is replanting the tooth, and the sooner, the better! Immediately replanting the tooth at the site of the injury is the best treatment. If the tooth that has been knocked out is a baby tooth, leave this tooth for the tooth fairy—baby teeth should not be replanted as it can cause damage to the developing adult tooth.

In cases where replantation cannot be done, the following guidelines can help ensure the best prognosis for the tooth in question.

Once you arrive at your dentist, treatment depends on where the tooth is (replanted or in storage solution) and how long ago the injury occurred. In most cases, the tooth will require a root canal after emergency care is rendered. Any lacerations will be sutured, a splint will be placed on the tooth, and antibiotics will be given. You may be referred to your physician to evaluate the need for a tetanus booster. At home, you will be given a special mouth rinse to use and a soft diet will be recommended for at least 2 weeks.

As with other types of dental trauma, follow-up is key! Your dentist will want to evaluate the tooth regularly to confirm that healing is progressing normally. If you have any questions about knocked out teeth, we are here to help!
