If the dentist replants the tooth within 30 minutes, the tooth has the best chance of survival. The root of the tooth should not be touched. The tooth should not be wrapped in tissues, handkerchiefs, or gauze. If the tooth is transported in a plastic or glass container, it should have a tight lid so the tooth and storage liquid are not spilled. Under no circumstances should the tooth be kept dry or stored in water.
Milk is one of the best storage mediums.
One of the best transport liquids is called Hank's Balanced Salt Solution, which is a medical research fluid and contains several ingredients such as sodium chloride, glucose, sodium bicarbonate, and potassium chloride. It's a good idea for coaches to have these solutions available in the event that a tooth is knocked out during competition. Once the tooth is replanted, it should be splinted. The patient should then return to the dentist within a week to 10 days for an exam and possible removal of the splint. Two of the most common complications of replantation of avulsed teeth are pulpal necrosis and root resorption.
