4SignsYourChildMayHaveaPoorBite

Although tooth decay is a major problem to watch for in your child’s teeth, it isn’t the only one. As their teeth transition from primary (“baby”) to permanent, you should also be on the lookout for a developing poor bite or malocclusion.

Although the signs can be subtle, you may be able to detect an emerging malocclusion, starting usually around age 6, if you know what to look for. Here are 4 signs your child may be developing a poor bite.

Excessive spacing. This is something that might be noticeable while the child still has their primary teeth. If you notice an excessive amount of space around the front teeth, the sizes of the jaws and the teeth may be disproportional.

Abnormal overlapping. The upper teeth normally just cover the bottom teeth when the jaws are closed. But a malocclusion may be forming if the lower teeth cover the upper (underbite), the upper teeth extend too far over the lower (deep bite) or there’s space between the upper and lower front teeth (open bite).

Different overlapping patterns. Watch as well for some of the teeth overlapping normally while others don’t, a sign of a cross bite. For example, the back upper teeth may cover their counterparts in a normal fashion while the lower front teeth abnormally overlap the top front. The roles here between front and back teeth can also be reversed.

Abnormal eruptions. Permanent teeth normally follow a pattern when erupting, but certain factors could disrupt the process. For example, a jaw that’s developed too small can cause crowding as incoming teeth vie for space; as a result, some permanent teeth may erupt out of their proper position. Likewise, if a baby tooth is out of its normal position or prematurely lost, the permanent tooth may erupt out of position too.

The good news with each of these developing bite problems is that we can correct them or at least minimize their future effect if caught early. So if you notice any of these signs or anything else out of the ordinary, see an orthodontist as soon as possible. It’s also a good idea to have your child undergo a thorough orthodontic evaluation around age 6.

TakeCareofYourDentalApplianceandItWillTakeCareofYou

What do a teenager with a poor bite, a senior citizen with multiple missing teeth or a middle-aged person with a teeth grinding habit all have in common? They may all depend on a dental appliance for better function or appearance.

There’s a wide variety of removable dental appliances like clear aligners or retainers for orthodontic treatment, dentures for tooth loss or night guards to minimize teeth grinding, just to name a few. But while different, they all share a common need: regular cleaning and maintenance to prevent them from triggering dental disease and to keep them functioning properly.

The first thing to remember about appliance cleaning is that it’s not the same as regular oral hygiene, especially if you have dentures. While they look like real teeth, they’re not. Toothpaste is a no-no because the abrasives in toothpaste designed for tooth enamel can scratch appliance surfaces. These microscopic scratches can develop havens for disease-causing bacteria.

Instead, use liquid dish detergent, hand soap or a specific cleaner for your appliance with a different brush from your regular toothbrush or a specialized tool for your particular appliance. Use warm but not very hot or boiling water: while heat indeed kills bacteria, the hot temperatures can warp the plastic in the appliance and distort its fit. You should also avoid bleach—while also a bacteria killer, it can fade out the gum color of appliance bases.

Be sure you exercise caution while cleaning your appliance. For example, place a towel in the sink basin so if the appliance slips from your hands it’s less likely to break hitting the soft towel rather than the hard sink. And while out of your mouth, be sure you store your appliance out of reach of small children and pets to avoid the chance of damage.

Cleaning and caring for your appliance reduces the risk of disease that might affect your gums or other natural teeth. It will also help keep your appliance working as it was designed for some time to come.

GetAheadofBiteProblemswithInterceptiveOrthodontics

At any given time some 4 million teens and pre-teens are wearing braces or other orthodontic appliances to correct a malocclusion (poor bite). While most cases are straightforward, some have difficulties that increase treatment time and cost.

But what if you could reduce some of these difficulties before they fully develop? We often can through interceptive orthodontics.

This growing concept involves early orthodontic treatment around 6 to 10 years of age with the goal of guiding the development of a child’s jaws and other mouth structures in the right direction. These early years are often the only time of life when many of these treatments will work.

For example, widening the roof of the mouth (the palate) in an abnormally narrow upper jaw takes advantage of a gap in the bone in the center of the palate that doesn’t fuse until later in adolescence. A device called a palatal expander exerts outward pressure on the back teeth to influence the jawbone to grow out. New bone fills in the gap to permanently expand the jaw.

In cases with a developing overbite (the upper front teeth extending too far over the lower teeth when closed), we can install a hinged device called a Herbst appliance to the jaws in the back of the mouth. The hinge mechanism coaxes the lower jaw to develop further forward, which may help avoid more extensive and expensive jaw surgery later.

Interceptive treatments can also be fairly simple in design like a space retainer, but still have a tremendous impact on bite development. A space maintainer is often used when a primary (“baby”) tooth is lost prematurely, which allows other teeth to drift into the empty space and crowd out the incoming permanent tooth. The wire loop device is placed within the open space to prevent drift and preserve the space for the permanent tooth.

To take advantage of these treatments, it’s best to have your child’s bite evaluated early. Professional organizations like the American Association of Orthodontists (AAO) recommend a screening by age 7. While it may reveal no abnormalities at all, it could also provide the first signs of an emerging problem. With interceptive orthodontics we may be able to correct them now or make them less of a problem for the future.

TheTimelyUseofaPalatalExpanderCouldHelpCorrectaCross-Bite

While crooked teeth are usually responsible for a malocclusion (poor bite), the root cause could go deeper: a malformed maxilla, a composite structure composed of the upper jaw and palate. If that’s the case, it will take more than braces to correct the bite.

The maxilla actually begins as two bones that fit together along a center line in the roof of the mouth called the midline suture, running back to front in the mouth. The suture remains open in young children to allow for jaw growth, but eventually fuses during adolescence.

Problems arise, though, when these bones don’t fully develop. This can cause the jaw to become too narrow and lead to crowding among the erupting teeth and a compromised airway that can lead to obstructive sleep apnea. This can create a cross-bite where the upper back teeth bite inside their lower counterparts, the opposite of normal.

We can remedy this by stimulating more bone growth along the midline suture before it fuses, resulting in a wider maxilla. We do this by installing a palatal expander, an appliance that incrementally widens the suture to encourage bone formation in the gap, which over time will widen the jaw.

An expander is a metal device with “legs” extending out on both sides and whose ends fit along the inside of the teeth. A gear mechanism in the center extends the legs to push against the teeth on both sides of the jaw. Each day the patient or caregiver uses a key to give the gear a quarter turn to extend the legs a little more and widen the suture gap. We remove the expander once the jaw widens to the appropriate distance.

A palatal expander is an effective, cost-efficient way to improve a bite caused by a narrow jaw, but only if attempted before the bones fuse. Widening the jaw after fusion requires surgery to separate the bones — a much more involved and expensive process.

To make sure your child is on the right track with their bite be sure to see an orthodontist for an evaluation around age 6. Doing so will make it easier to intervene at the proper time with treatments like a palatal expander, and perhaps correct bite problems before they become more expensive to treat.

HowKathyBatesRetainsHerMovie-StarSmile

In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.

When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”

Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.

There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.

By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.

So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.

If you would like more information about orthodontic retainers, please contact us or schedule an appointment for a consultation. You can learn more about this topic in the Dear Doctor magazine articles “Why Orthodontic Retainers?” and “The Importance of Orthodontic Retainers.” The interview with Kathy Bates appears in the latest issue of Dear Doctor.
