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.

Everyone knows that in the game of football, quarterbacks are looked up to as team leaders. That's why we're so pleased to see some NFL QB's setting great examples of… wait for it… excellent oral hygiene.
First, at the 2016 season opener against the Broncos, Cam Newton of the Carolina Panthers was spotted on the bench; in his hands was a strand of dental floss. In between plays, the 2105 MVP was observed giving his hard-to-reach tooth surfaces a good cleaning with the floss.
Later, Buffalo Bills QB Tyrod Taylor was seen on the sideline of a game against the 49ers — with a bottle of mouthwash. Taylor took a swig, swished it around his mouth for a minute, and spit it out. Was he trying to make his breath fresher in the huddle when he called out plays?
Maybe… but in fact, a good mouthrinse can be much more than a short-lived breath freshener.
Cosmetic rinses can leave your breath with a minty taste or pleasant smell — but the sensation is only temporary. And while there's nothing wrong with having good-smelling breath, using a cosmetic mouthwash doesn't improve your oral hygiene — in fact, it can actually mask odors that may indicate a problem, such as tooth decay or gum disease.
Using a therapeutic mouthrinse, however, can actually enhance your oral health. Many commonly available therapeutic rinses contain anti-cariogenic (cavity-fighting) ingredients, such as fluoride; these can help prevent tooth decay and cavity formation by strengthening tooth enamel. Others contain antibacterial ingredients; these can help control the harmful oral bacteria found in plaque — the sticky film that can build up on your teeth in between cleanings. Some antibacterial mouthrinses are available over-the-counter, while others are prescription-only. When used along with brushing and flossing, they can reduce gum disease (gingivitis) and promote good oral health.
So why did Taylor rinse? His coach Rex Ryan later explained that he was cleaning out his mouth after a hard hit, which may have caused some bleeding. Ryan also noted, “He [Taylor] does have the best smelling breath in the league for any quarterback.” The coach didn't explain how he knows that — but never mind. The takeaway is that a cosmetic rinse may be OK for a quick fix — but when it comes to good oral hygiene, using a therapeutic mouthrinse as a part of your daily routine (along with flossing and brushing) can really step up your game.
A blow to the face can result in a variety of injuries to your jaws and the temporomandibular joints (TMJs) that join the lower jaw to the skull. Only a thorough examination can determine the type and extent of the injury, and how to treat it.
The pain you feel in your jaw may indicate a direct injury, usually near the joint. This could mean the joint head (condyle) has dislocated, or moved out of the joint space. It could also mean you’ve fractured your lower jaw, most commonly just below the head of the joint.
Jaw pain can also indicate structures near the jaw and joint have been damaged and the jaw is indirectly affected. In some cases a damaged tooth may be radiating pain signals through the jaw (along similar nerve paths). More likely, trauma to soft tissue near the jaw joint has swelled with inflammation, putting pressure on the joint and temporarily stopping the condyle from seating fully in the joint space.
Any of these injuries can also cause painful muscle spasms, a defensive reaction from the body that causes muscles on either side of the jaw to limit movement preventing further damage (a natural splint, if you will). Thus, the pain may be compounded by a diminished range of motion when you try to chew or speak.
It’s important, therefore, to determine the exact cause of pain and limited movement before commencing treatment. Spasms and inflammation are usually treated with muscle relaxant drugs and anti-inflammatory pain relievers. In the case of a dislocation, gentle manipulation can ease the condyle back into the joint space. A fracture would require more extensive treatment, including repositioning broken bone and immobilizing the jaw from movement to allow healing. In the most severe cases, surgical treatment may be necessary to internally immobilize the joint.
If you sustain an injury that results in jaw swelling and pain, you should see us without delay. The sooner we can diagnose and begin the proper treatment for your injury, the less likely you’ll encounter long-term problems and the sooner you’ll be pain and swelling free.
