What do I do if I accidentally loose a tooth?

Avulsion, or accidental loss of permanent teeth, is the most serious of all dental injuries. The outcome of treatment is dependent on the measures taken immediately after a traumatizing incident. Replanting the avulsed tooth is the treatment of choice accompanied by emergency management and treatment plan.
 
If a tooth is easily replanted in its original location, replace the tooth  and visit your dentist within the next 60 minutes from the time of the avulsion. (If it is not possible to replant the tooth, save the tooth in a small container with saliva from the original source and get to the nearest dentist within the hour.) Your dentist will clean the tooth and affected area with necessary rinses, splint the tooth, and provide  a prescription for systemic antibiotics. A tetanus booster may be recommended by your primary care physician if the tooth has contacted soil. You should undergo soft food diet for the next two weeks and maintain proper oral hygiene with a soft bristle toothbrush and a prescription for chlorhexidine mouth rinse. Within 7-10 days a root canal treatment will be performed. 

If you see someone loose their tooth due to trauma, follow these directions and call your family dentist for immediate treatment.
