Accidents do happen, especially if you or a family member has an active lifestyle. One such risk, especially for someone playing a contact sport, is having a tooth knocked out.
But as extreme as this injury can be, it doesn't necessarily mean the tooth is lost forever. Gum (or periodontal) cells remaining on the tooth root can regenerate and regain their attachment with the periodontal ligament that holds teeth in place. But you have to act quickly—the longer the tooth is out of the socket, the more likely these cells will dry out and die.
So, by doing the following within 5-20 minutes of the injury (and the earlier the better), that knocked-out tooth has a reasonable chance of survival.
Locate and clean the tooth. Your first priority is to find the missing tooth and clean it of any debris with clean water. Be sure not to touch the root of the tooth and only handle the tooth by the crown (the visible part of a tooth when it's in the mouth).
Insert the root end into the empty socket. Still holding the tooth by the crown, insert the opposite root end into the empty socket. Orient the crown properly, but don't worry about getting it in just right—the follow-up with the dentist will take care of that. You will, however, need to apply some pressure to get it to seat firmly.
Secure the tooth. Place a piece of clean gauze or cloth between the reinserted tooth and its counterpart on the other jaw. Then, have the person bite down on the cloth and hold it. This will help secure the tooth in place while you travel to the dentist.
Seek dental care immediately. It's important to see a dentist immediately to adjust the tooth's position and to possibly splint the tooth to better secure it while it heals. If a dentist isn't available, then visit a local emergency room instead.
Taking these actions on the scene could mean the difference between saving and losing a tooth. But act quickly—the sooner you initiate first aid for a knocked-out tooth, the better its chances for long-term survival.

Finding out you have a cavity isn't the best of news. But finding out it's a root cavity is even worse: if not treated, the decay can spread more rapidly than a cavity occurring in the tooth's crown surfaces.
Our teeth are basically composed of two parts: the crown, the visible tooth above the gum line, and the roots, the hidden portion beneath the gums. The root in turn fits into a bony socket within the jaw to help hold the tooth in place (along with attached gum ligaments).
A tooth crown is covered by an ultra-hard layer of enamel, which ordinarily protects it from harmful bacteria. But when acid produced by bacteria comes into prolonged contact with enamel, it can soften and erode its mineral content and lead to a cavity.
In contrast to enamel, the roots have a thin layer of material called cementum. Although it offers some protection, it's not at the same performance level as enamel. But roots are also normally covered by the gums, which rounds out their protection.
But what happens when the gums shrink back or recede? This often occurs with gum disease and is more prevalent in older people (and why root cavities are also more common among seniors). The exposed area of the roots with only cementum standing in the way of bacteria and acid becomes more susceptible to cavity formation.
Root cavities can be treated in much the same way as those that occur in the crown. We first remove any decayed tooth structure with a drill and then place a filling. But there's also a scenario in which the cavity is below the gum line: In that case, we may need to gain access to the cavity surgically through the gums.
If you have exposed root areas, we can also treat these with fluoride to strengthen the area against cavity formation. And, as always, prevention is the best treatment: maintain a daily schedule of brushing and flossing and regular dental cleanings to remove bacterial plaque.
Because decay can spread within a tooth, dealing with a root cavity should be done as promptly as possible. But if we diagnose and initiate treatment early, your chances of a good outcome are high.

Root canals often get a bum rap. Although the procedure saves millions of teeth every year, it's often erroneously portrayed as an unpleasant experience. And if that wasn't enough, a long-discredited medical theory has found new life on the internet asserting root canals are a health danger.
First off, root canals play an immensely important role in treating teeth with advanced decay. If not promptly treated, a cavity can turn into a major infection of the interior tooth pulp and root canals, and ultimately the supporting bone. Teeth with this level of decay are not long for this world.
A root canal treatment stops this disease process in its tracks. After numbing the tooth and surrounding gums, we drill a small hole into the tooth's interior and then remove all of the infected tissue within the pulp and root canals. After disinfecting these areas, we fill them with a rubber-like substance called gutta percha.
After sealing off the access hole—and later capping the tooth with a life-like crown—the tooth is secure from further decay. And, by the way, the procedure doesn't hurt, thanks to local anesthesia. If anything, any pain caused by the decay attacking the tooth's nerves has now been alleviated.
So, what about the idea floating on the Web that root canals are dangerous? The "root" for this conjecture is a theory by Weston Price, an early 20th Century dentist, that leaving a "dead" body part in the body leads to various health problems (including cancer). That would include a root-canaled tooth, which has had the living tissue in the pulp removed.
There's just one problem—Weston's theory was fully investigated in the 1950s and overwhelmingly discredited. The supposed cancer threat was also reviewed in a 2013 study, which found no link between root canals and increased cancer risk. In fact, dental patients who had undergone several root canals had a diminished risk.
Like all other health procedures, root canals have some risks of complication. But those complications are far from life-threatening—it's tooth-saving benefits are often worth the risk. So, fear not if your dentist says you need a root canal. It won't hurt and it won't endanger your health—and it could save your tooth.
