Your child's permanent teeth come in gradually, starting just as they begin losing their primary ("baby") teeth and not ending until late adolescence or early adulthood. That's when the third molars or "wisdom teeth" close out the process.
Because of their late arrival, wisdom teeth have a high potential for dental problems. With a greater chance of crowding or obstruction by other teeth, wisdom teeth often get stuck fully or partially below the gums and bone (impaction) or erupt out of position. In one study, 7 in 10 people between the ages of 20 and 30 will have at least one impacted wisdom tooth at some time in their lives.
It's not surprising then that wisdom teeth are among the most extracted teeth, to the tune of about 10 million per year. Besides those already diseased or causing bite problems, many are removed preemptively in an attempt to avoid future problems.
But wisdom teeth usually require surgical extraction by an oral surgeon, which is much more involved than a simple extraction by a general dentist. Given the potential consequences of surgical extraction, is it really necessary to remove a wisdom tooth not creating immediate problems?
That's not an easy question to answer because it's often difficult to predict a wisdom tooth's developmental track. Early on it can be disease-free and not causing any problems to other teeth. But as some researchers have found, one in three wisdom teeth at this stage will later develop disease or create other issues.
For many dentists, the best approach is to consider extraction on a case by case basis. Those displaying definite signs of problems are prime for removal. But where there are no signs of disease or other issues, the more prudent action may be to keep a watchful eye on their development and decide on extraction at some later date.
More than likely, your dentist will continue to have an ongoing discussion with you about the state of your child's wisdom teeth. While extraction is always an option, wisdom teeth that aren't yet a problem to dental health may be best left alone.
On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

Among dental restorations, implants are the closest prosthetic we have to real teeth. They not only replace the visible crown, but the titanium post imbedded in the jawbone adequately substitutes for the tooth root. Because of their unique design, implants are not only life-like, they’re highly durable and could potentially last for decades.
But while their success rate is remarkably high (more than 95% exceed the ten-year mark), they can fail. Ironically, one possible cause for implant failure is periodontal (gum) disease. Although an implant’s materials are themselves impervious to disease, the tissues and underlying bone that support the implant aren’t. If these natural tissues become infected, the secure hold the implant has can weaken and fail.
A gum infection usually begins with dental plaque, a thin biofilm of bacteria and food particles that builds up on tooth surfaces. Certain strains of bacteria within plaque can infect the gums. One particular form of the disease known as peri-implantitis starts as an initial infection and ensuing inflammation of gum tissues around an implant. The disease can quickly spread down to the bone and destroy the integration between the bone and the implant that helps keep the implant in place.
That’s why it’s important for you to keep the implant and the tissues around it clean of plaque, just as you would the rest of your natural teeth. This requires daily brushing and flossing around the implant and other teeth, and visiting your dentist regularly for more thorough dental cleanings.
You should also be alert to any signs of disease, especially around implants: gum redness, swelling, bleeding or pus formation. Because of the rapidity with which peri-implantitis can spread, you should see your dentist as soon as possible if you notice any of these signs.
Preventing gum disease, and treating it promptly if it occurs, is a key part of implant longevity. Preserving your overall dental health will help make sure your implant doesn’t become a loss statistic.
All-natural fruit juice with no additives: now what could be wrong with that? Nothing—unless your child is over-indulging. Too much of even natural fruit juice could increase their risk of tooth decay.
To understand why, we first need to look at the real culprit in tooth decay: mouth acid produced by oral bacteria as a byproduct of their digestion of sugar. Acid at high levels softens and erodes tooth enamel, which causes tooth decay. Acid levels can rise as populations of bacteria increase often fueled by sugar, one of bacteria's primary food sources.
And not just the added sugar found in soft drinks, snacks or candies—even fructose, the natural sugar found in fruit, can feed bacteria. To lower the risk of tooth decay, dentists recommend limiting the daily amount of sugar a child consumes, including natural fruit juices without added sugar.
That doesn't mean you should nix natural fruit juices altogether—they remain a good source of vitamins, minerals and other nutrients. But you'll need to keep your child's juice consumption within moderation.
As a guide, the American Academy of Pediatrics (AAP) has issued consumption recommendations for children regarding all-natural fruit juice. The academy recommends the following daily juice amounts by age:
- 7-18: 8 ounces (1 cup) or less;
- 4-6: 6 ounces or less;
- 1-3: 4 ounces or less;
- Under 1: No juice at all.
You can further reduce your child's decay risk by limiting their juice intake to mealtimes, a good practice with any sweetened beverage. Sipping through the day on juice or other sweetened beverages can cause some sugar to stay in the mouth over long periods. This can interfere with the natural ability of saliva to neutralize any acid buildup.
If you're wondering what children could drink instead of juice, low-fat or non-fat milk is an acceptable choice. But the most tooth-friendly liquid to drink is plain water. Drinking nature's hydrator is not only better for their overall health, by reducing the risk of tooth decay, it's also better for their teeth.

Dental implants have soared in popularity thanks to their life-likeness, functionality and durability. But these prized qualities have also created an ironic downside—people are much more likely to replace a tooth with an implant rather than go through the time and effort to preserve it.
We say downside because even though an implant is as close to a real tooth as we can now achieve in dentistry, it still can't rival the real thing. It's usually in your long-term health interest to save a tooth if reasonably possible. And, there are effective ways to do so.
Most dental problems arise from two common oral diseases. One is tooth decay, caused by contact with acid produced by bacteria living in dental plaque. We can often minimize the damage by treating the early cavities decay can create. But if we don't treat it in time, the decay can advance into the tooth's pulp chamber, putting the tooth in danger of loss.
We can intervene, though, using root canal therapy, in which we drill into the tooth to access its interior. We clean out the decayed tooth structure, remove the diseased pulp tissue and fill the empty chamber and root canals to seal the tooth and later crown it to further protect it from re-infection.
Periodontal (gum) disease also begins with bacteria, but in this case the infection is in the gum tissues. Over time the ensuing inflammation locks into battle with the plaque-fueled infection. This stalemate ultimately weakens gum attachment, the roots and supporting bone that can also increases risk for tooth loss.
We can stop a gum infection through a variety of techniques, all following a similar principle—completely removing any accumulated plaque and tartar from the teeth and gums. This stops the infection and starts the process of gum and bone healing.
You should be under no illusions that either of these approaches will be easy. Advanced tooth decay can be complex and often require the skills of an endodontist (a specialist in root canals). Likewise, gum disease may require surgical intervention. But even with these difficulties, it's usually worth it to your dental health to consider saving your tooth first before you replace it with an implant.
