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.

The subject of allergies covers a wide swath in medicine. Among other things, people have allergic reactions to animal fur, various foods and plant pollen. The effects are equally wide-ranging, anything from a mild rash to anaphylaxis, a life-threatening shutdown of the body's vital systems.
Approximately 5% of people are also allergic to various metals including nickel, cobalt, chromium and gold. Reactions to metal can occur when an allergic person comes in contact with items like jewelry, clothing or even mobile phones. There's even a chance of a metal allergy reaction from certain kinds of dental work.
It's unlikely, though, that you should be concerned if you're considering dental treatment or cosmetic work to upgrade your smile. Although allergic reactions like inflammation or a rash have been known to occur with amalgam “silver” fillings, it's quite rare. It's even less of a concern since “tooth-colored” materials for fillings are now outpacing the use of amalgam fillings, which are used in out-of-sight back teeth.
Of course, metal is used for other dental treatments besides fillings, including the most popular of tooth replacement systems, dental implants. An implant is essentially a metal post, usually made of pure titanium or a titanium alloy, which is imbedded into the jawbone. Even so, there's little chance you'll develop an allergic reaction to them.
For one thing, titanium is highly prized in both medical and dental treatments because of its biocompatibility. This means titanium devices like prosthetic joints and implants won't normally disrupt or cause reactions with human tissue. Titanium is also osteophilic: Bone cells readily grow and adhere to titanium surfaces, a major reason for dental implants' long-term durability.
That's not to say titanium allergies don't exist, but their occurrence is very low. One recent study detected a titanium allergy in only 0.6% of 1,500 implant patients who participated.
At worst, you may need to consider a different type of tooth replacement restoration in the rare chance you have a titanium allergy. More than likely, though, you'll be able obtain implants and enjoy the transformation they can bring to your smile.

If you’re pregnant, you may find yourself pondering decisions you didn’t have to think about before. Should you have that glass of wine… or skip it, because of the alcohol; go for the sushi… or avoid uncooked foods; take the pain reliever… or live with the headache. And if you have a toothache — or even if you’re overdue for a checkup and a cleaning — you may also be wondering whether having dental treatment (especially treatment that might involve local anesthetics) is safe for you and your developing baby.
Fortunately, a study that recently appeared in the Journal of the American Dental Association (JADA) should let expectant moms breathe a little easier. The research concludes that it’s safe for pregnant women to undergo dental treatment, including procedures that use local anesthetics.
And that’s good news indeed, because while maintaining good oral health during pregnancy is critical for the developing baby, many expectant moms experience problems during this period.Â Some common issues include a higher risk of tooth decay due to increased carbohydrate consumption, and sore or bleeding gums from a condition called pregnancy gingivitis.
According to the study’s lead author, Aharon Hagai, D.M.D., "[Pregnancy] is a crucial period of time in a woman’s life, and maintaining oral health is directly related to good overall health." Yet, as Dr. Hagai notes, pregnant women sometimes avoid the dentist even if they have a problem. So his team set out to determine whether having dental treatment with anesthesia affected the outcome of pregnancies. They compared a total of 1,004 women, some of whom had dental treatment with local anesthesia, and some who did not.
The research showed there was no significant difference between the two groups. This applied in terms of both major medical problems (such as cleft palate, heart defects or cerebral palsy) and other issues, including low birth weight and preterm delivery. Dr. Hagai summed it up this way: "We aimed to determine if there was a significant risk associated with dental treatment with anesthesia and pregnancy outcomes. We did not find any."
So if you’re pregnant, there’s one less thing to worry about. Go ahead and schedule your routine dental check up — and remember that it is particularly important to have cleanings during pregnancy. Â If you experience changes in your oral health, don’t hesitate to come in for an office visit and cleaning; that way, you can make sure your hormonal changes are not playing havoc with your gums. There is an old saying in some cultures that for every child a woman has, she loses a tooth. Don’t let that happen to you.
