YourChildsImpactedFrontTeethcanbeSaved-butDontWaittooLong

Children's permanent teeth normally erupt over several years after first forming below the gum line. All their permanent teeth should come in by the time they reach early adolescence.

Unfortunately, this process doesn't always happen as it should. If the erupting teeth become crowded due to a poor bite (malocclusion), teeth still to come in may not have enough room to fully erupt. They become impacted, a condition in which the visible crown remains partially or completely submerged below the gum line.

Impacted teeth create consequences for other teeth and dental health overall. They more readily cause abscesses (a localized infection within the gum tissue) and can damage the roots of nearby teeth. Impacted front canine (eye) teeth can interfere with bite function and their visual absence mars an otherwise attractive smile.

If your child's canine teeth have failed to erupt properly, there is a way to help them fully come in if you act before their mouth structure fully matures. The first step is an orthodontic evaluation of their entire bite. This will determine if there's enough space to move other teeth to make room for the impacted canines.

If so, we would then find the exact position of the impacted teeth using x-rays and possibly cone beam CT scanning for a detailed three-dimensional image. The teeth could be in a variety of positions, such as angled toward the roof of the mouth or cheek or buried high in the jawbone. If the teeth are too far out of position the best course of action may be to remove them and replace them later with a dental implant.

If the impacted teeth, though, are in a feasible position for retrieval, we first expose each tooth through the gums with a minor surgical procedure and bond a small bracket to it. We then attach a small gold chain to the bracket that loops over an orthodontic appliance attached to other teeth. The appliance will exert pressure over several months to pull the tooth into proper position.

If successful, your child will gain the use of these important teeth and a more attractive appearance. But don't delay — this desired outcome will become much harder if not impossible to attain as their teeth and jaws continue to develop.

SealantsCouldProtectYourChildsTeethFromFutureProblems

Teeth lost to tooth decay can have devastating consequences for a child’s dental health. Not only can it disrupt their current nutrition, speech and social interaction, it can also skew their oral development for years to come.

Fortunately, we have a number of preventive tools to curb decay in young children. One of the most important of these, dental sealants, has been around for decades. We apply these resin or glass-like material coatings to the pits and crevices of teeth (especially molars) to help prevent the buildup of bacterial plaque in areas where bacteria tend to thrive.

Applying sealants is a simple and pain-free process. We first brush the coating in liquid form onto the teeth’s surface areas we wish to protect. We then use a special curing light to harden the sealant and create a durable seal.

So how effective are sealants in preventing tooth decay? Two studies in recent years reviewing dental care results from thousands of patients concluded sealants could effectively reduce cavities even four years after their application. Children who didn’t receive sealants had cavities at least three times the rate of those who did.

Sealant applications, of course, have some expense attached to them. However, it’s far less than the cost for cavity filling and other treatments for decay, not to mention future treatment costs resulting from previous decay. What’s more important, though, is the beneficial impact sealants can have a child’s dental health now and on into adulthood. That’s why sealants are recommended by both the American Dental Association and the American Academy of Pediatric Dentistry.

And while sealants are effective, they’re only one part of a comprehensive strategy to promote your child’s optimum dental health. Daily brushing and flossing, a “tooth-friendly” diet and regular dental cleanings and checkups are also necessary in helping to keep your child’s teeth healthy and free of tooth decay.

MargotRobbieKnowsAGreatSmileIsWorthProtecting

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.
