HeadOffaCrossbiteatthePassWithThisOrthodonticAppliance

At what age should you begin treating a poor bite? Many might say with braces around late childhood or early adolescence. But some bite problems could be addressed earlier—with the possibility of avoiding future orthodontic treatment.

A crossbite is a good example. In a normal bite, all of the upper teeth slightly cover the lower when the jaws are shut. But a crossbite occurs when some of the lower teeth, particularly in back, overlap the upper teeth. This situation often happens when the upper jaw develops too narrowly.

But one feature of a child's mouth structure provides an opportunity to intervene and alter jaw development. During a child's early years, the palate (roof of the mouth) consists of two bones next to each other with an open seam running between them. This seam, which runs through the center of the mouth from front to back, will fuse during puberty to form one continuous palatal bone.

An orthodontist can take advantage of this separation if the jaw isn't growing wide enough with a unique device called a palatal expander. This particular oral appliance consists of four, thin metal legs connected to a central mechanism. The orthodontist places the expander against the palate and then uses the mechanism to extend the legs firmly against the back of the teeth on both sides of the jaw.

The outward pressure exerted by the legs also widens the seam between the two palatal bones. The body will respond to this by adding new bone to the existing palatal bones to fill in the widened gap. At regular intervals, the patient or a caregiver will operate the mechanism with a key that will continue to widen the gap between the bones, causing more expansion of the palatal bones until the jaw has grown to a normal width.

The palatal expander is most effective when it's applied early enough to develop more bone before the seam closes. That's why it's important for children to undergo bite evaluation with an orthodontist around age 6. If it appears a bite problem is developing, early interventions like a palatal expander could slow or stop it before it gets worse.

FluorideTreatmentsGiveYourChildAddedProtectionAgainstCavities

When it comes to helping your child avoid tooth decay, it's all hands on deck. Tooth decay can not only harm their current set of primary teeth, but the loss of even one tooth could lead to bite problems later on.

And, even if you're doing all the right things—daily brushing and flossing, limiting sugar consumption and regular dental visits—your child might still develop cavities. If so, it may be necessary to add a boost of prevention with topical fluoride applied by your dentist.

With its enamel-strengthening properties, fluoride plays an important role in dental disease prevention. For decades, manufacturers have added fluoride to toothpaste. And, many water utilities now add tiny amounts of fluoride to their drinking supply.

According to a number of studies, these fluoride applications are effective weapons against tooth decay. But direct applications of fluoride to tooth surfaces can provide even greater benefit to children with a higher susceptibility for decay.

Topical fluoride is usually applied by means of a gel, foam or varnish. In varnish form, it's brushed on the teeth, while dentists apply the foam solution within a tray fitted around the teeth. The gel application can be administered by either method.

Although these topical applications use a higher concentration of fluoride than you find in toothpaste, it poses no serious danger to a child's health. But because high doses of fluoride can lead to staining, topical applications are only administered periodically during childhood.

The only short-term health concern is if the child accidentally swallows some of the mixture during application. This can cause symptoms like an upset stomach, vomiting or headache. Dentists, however, take a number of precautions to prevent accidental ingestion in order to avoid these unpleasant side effects.

The benefits, though, appear to well outweigh this minor risk. In a review of several scientific studies involving nearly 10,000 children, there was an average 28% reduction in decayed, missing or filled teeth in those children that underwent topical fluoride treatments.

If you want to know more about topical fluoride treatments and whether they can help your child avoid tooth decay, talk to your dentist. This fluoride booster could help further protect them from this destructive dental disease.

ShouldYouTakeanAntibioticBeforeImplantSurgery

Although getting an implant requires surgery, it's usually a minor affair. Chances are good that after just a few days recuperation you'll be back completely to your normal activities.

But like many other minor surgeries, an implant procedure does pose a slight risk of post-op infection. That's especially so with any dental procedure like implant surgery, since the mouth harbors numerous strains of bacteria that could escape into the bloodstream. For most people, though, a post-op infection doesn't pose a major problem since their immune system kicks in immediately to defeat it.

But some patients with less than robust immune systems or other health problems can have serious complications from an infection. Among other things, infected tissues around an implant may not heal properly, putting the implant at significant risk for failure.

If you have a condition that makes a post-op infection problematic, your dentist or physician may recommend you take an antibiotic before your procedure. Known as prophylactic (preventive) antibiotic treatment, it's intended to give a weakened immune system a head-start on any potential infection after a procedure.

Using antibiotics in this way has been a practice for several decades, and at one time were recommended for a wide list of conditions. That's changed in recent years, though, as evidence from numerous studies seems to show the risk to benefit ratio isn't significant enough to warrant its use in all but a handful of conditions.

Both the American Dental Association and the American Heart Association recommend prophylactic antibiotics for patients with prosthetic heart valves, past infective endocarditis, a heart transplant and some congenital heart conditions. Some orthopedists may also recommend it for patients with prosthetic joints.

Even if you don't fall into these particular categories, prophylactic antibiotics may still be beneficial if you have a compromised immune system or suffer from a disease like diabetes or lung disease. Whether or not a prophylactic antibiotic is a prudent step given your health status is a discussion you should have with both your physician and your dentist.

If they feel it's warranted, it can be done safely in recommended doses. If your health isn't as robust as it could be, the practice could give you a little added insurance toward a successful implant outcome.
