We Americans love our sports, whether as participants or spectators. But there's also a downside to contact sports like soccer, football or basketball: a higher risk of injury, particularly to the mouth and face. One of the most severe of these is a knocked out tooth.
Fortunately, that doesn't necessarily mean it's lost: The tooth can be reinserted into the empty socket and eventually return to normal functionality. But it must be done as soon as possible after injury. The more time elapses, the lower the chances of long-term survival.
That's because of how teeth are held in place in the jaw, secured by an elastic, fibrous tissue known as the periodontal ligament. When a tooth is knocked out some of the ligament's periodontal cells remain on the tooth's root. If these cells are alive when the tooth is reinserted, they can regenerate and reestablish attachment between the ligament and the tooth.
Eventually, though, the cells can dry out and die. If that has already happened before reinsertion, the tooth's root will fuse instead with the underlying bone. The tooth may survive for a short time, but its roots can eventually dissolve and the tooth will be lost.
Your window of opportunity for taking advantage of these live periodontal cells is only 5-20 minutes with the best chances in those earlier minutes. You should, therefore, take these steps immediately after an injury:
- Find the tooth, hold it by the crown (not the root end), and rinse off any debris with clean water;
- Reinsert the root end into the empty socket with firm pressure;
- Place clean gauze or cloth in the person's mouth between the tooth and the other jaw, and ask them to bite down gently and hold their bite;
- Seek dental or emergency medical care immediately;
- If you're unable to reinsert the tooth, place it quickly in a container with milk and see a dentist immediately.
You can also obtain an Android or IOS smartphone app developed by the International Association of Dental Traumatology called ToothSOS, which will guide you through this process, as well as for other dental emergencies. The quicker you act, the better the chances that the injured person's knocked out tooth can be rescued.

Infancy is perhaps the only time in a person's life where a smile with just a few tiny teeth is still endearing. More will come—and then each will gradually depart, succeeded by permanent replacements.
That short lifespan, though, doesn't diminish their importance. Primary teeth not only provide children the ability to eat solid food and develop speech, but they set the stage for future dental health.
The latter arises from primary teeth's role as placeholders for incoming permanent teeth. Because permanent teeth eruption occurs in stages, primary teeth prevent earlier erupted teeth from drifting into the space intended for a later tooth. If they're lost prematurely and other teeth crowd into the space, the intended tooth may not have enough room to erupt properly, cascading from there into a poor bite (malocclusion).
The most common reason for premature loss is an aggressive form of tooth decay in children under 6 called early childhood caries (ECC). About one in four U.S. children encounter ECC, with those in poverty at higher risk. Infection in one tooth can spread to others, including newly erupted permanent teeth.
The goal then is to prevent ECC as much as possible, and initiate prompt treatment should it still occur. A good prevention strategy has two prongs: the actions and habits of parents or caregivers; and the prevention and treatment measures taken by dental providers.
At home, it's important that you wipe your newborn's gums with a clean, damp cloth after each feeding to reduce bacterial growth. As teeth erupt, switch then to gentle brushing with a rice grain-sized amount of baby toothpaste. You should also limit their sugar consumption, including not allowing them to sleep with a bedtime bottle of any liquid other than water.
It's also important that you start your child's regular dental visits around their first birthday. This allows us to detect any developing cavities, as well as apply sealants and topical fluoride to help prevent decay. And should a cavity develop, regular visits help ensure prompt treatment to preserve the tooth.
Your child's set of primary teeth only last a few short years, but their contribution echoes for a lifetime. Taking these measures to protect them from tooth decay ensures they'll fully make that contribution.
