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.

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.
Orthodontists are able to achieve attractive results with traditional braces moving several teeth into a better position. In a way, braces are the original “smile makeover.”
But orthodontic treatment can also be useful if only a few teeth (like the two upper front teeth) need to be moved slightly. A treatment known as minor tooth movement takes only a few months as opposed to years for traditional multiple teeth movement, and with removable appliances that may use small springs or elastics to place gentle pressure on teeth to move them.
So, what constitutes a minor tooth movement scenario? As with any dental condition, the first step is a complete dental examination, particularly the bite. We also need to determine if enough room exists to close any space without compromising the bite with the opposing teeth, and if the teeth and their roots are in a good position to allow minor movement — otherwise, more extensive treatment may be called for. The surrounding gum tissues and bone also need to be healthy and disease-free, especially in adults.
We may also need to look more closely at the actual cause for a front tooth gap. If the gap is the result of the tongue habitually pressing against the back of the teeth and pushing them forward, it may then be difficult or impossible to close the gap with minor tooth movement techniques. The cause may also originate from the frenum (a thin, muscular tissue that rises up from between the upper front teeth toward the lip) if it has extended too far between the teeth. In this case we may first need to surgically remove some of the frenum tissue before attempting orthodontics or the teeth may gradually move back apart after closing the gap.
Although minor tooth movement normally doesn’t take as long as braces, it may still require several months. And just like with braces, you will need to wear a retainer for several months afterward until the bone stabilizes around the new position. Still, minor tooth movement could have a major impact on your smile.

You may not always be able to tell if your child's bite isn't developing properly. Â That's why you should have them undergo an orthodontic evaluation around age 6 to uncover any emerging problems with tooth misalignment.
Still, there are some visible signs all's not well with their bite. As the primary (baby) teeth give way, the permanent teeth erupt sequentially around ages 6 to 8. As they come in, you should notice that each tooth fits uniformly next to each other without excessive gaps or, on the other end of the spectrum, not crowded together in crooked fashion. Upper teeth should also fit slightly over the lower teeth when the jaws are shut.
If their teeth appearance deviates from these norms, they may have a bite problem. Here are 4 abnormalities you should watch for.
Underbite or deep bite. As we mentioned, the front teeth should cover the lower teeth with the jaws shut. In an underbite, the reverse happens — the lower teeth are in front of the upper teeth. It's also a problem if the upper teeth cover the lower teeth too much (often referred to as “deeply”).
Open bite. This occurs when there's a gap between the upper and lower front teeth while the jaws are shut together. One possible cause is late thumb sucking, which can put undue pressure on the front teeth and cause them to develop too far forward while forcing the bottom front teeth further backwards.
Crossbites. This kind of bite occurs when some of the teeth don't fit properly over their counterparts, while others do. Crossbites can occur anywhere in the mouth, for example the upper front teeth fitting behind the lower front teeth while the back teeth overlap normally, or the reverse (front normal, back abnormal).
Misalignments and Abnormal Eruptions. Sometimes upper teeth may align too far forward, a situation known as protrusion. Conversely, lower teeth (or the jaw itself) may come in too far back (retrusion). Because a primary tooth might be out of position or not lost in the proper sequence, a permanent tooth might noticeably erupt out of its proper position.
If you notice any of these situations with your child's teeth see your dentist or orthodontist soon for a full examination. If caught early, we may be able to take action that will lessen or even eliminate the problem.
Many otherwise attractive smiles have one noticeable blemish — a large gap between the two upper front teeth. If you have such a gap, there’s a solution that could transform your smile.
The most likely reason for the gap is an issue with a bit of muscle tissue between the gums and upper lip known as the frenum, part of the face’s muscular system. The frenum, though, can overdevelop and grow between the two front teeth into the front part of the palate (roof of the mouth). This can keep or push the teeth apart to form a gap.
To correct the issue, it’s first necessary to consult with an orthodontist, a specialist in bites and tooth alignment. It’s possible for there to be other factors contributing to the spacing including tongue thrusting or finger sucking habits, or missing or misaligned teeth. If the examination reveals an overly large frenum, then the treatment usually commences in two stages.
First, we would need to close the gap by the moving the teeth toward each other with some form of orthodontic appliance like braces or clear aligners. Once closed, the next stage would be to surgically remove the excess frenum tissue and cosmetically alter the gums if necessary.
The order of treatment is important — if you remove the frenum tissue first, any resulting scar tissue could prevent closing the gap with orthodontics. Further, cosmetic surgery on the gums beforehand could result in the loss of the papillae, the small triangular gum tissue between teeth, which results in an unattractive “black” hole.
A frenectomy, the procedure to remove the excess frenum, is a relatively minor procedure that can be performed by a periodontist (gum specialist), oral surgeon, or a general dentist with surgical training. The area is numbed with a local anesthetic, the tissue dissected with a small scalpel, and the resulting small wound closed with a few stitches (another option is to use a surgical laser to remove the frenum). Healing should be complete in about a week with only minor discomfort.
Depending on your individual circumstance, full treatment can take time. But in the end these otherwise routine dental procedures can have a huge impact — a more attractive smile without the noticeable gap.
