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.

About one-quarter of people have teeth that never developed. While most of these congenitally missing teeth are wisdom teeth, they can also include premolars or lateral incisors (the teeth right next to the two front teeth, the central incisors).
Missing teeth can have an adverse effect on smile appearance. But that’s not all: because each type of tooth performs a specific function, one or more missing teeth can lead to bite problems and disruption of dental function. In the case of missing lateral incisors, the canines (eye teeth) normally positioned beside and toward the back of the mouth from them may begin to drift into the empty space and grow next to the central incisors. This can result in greater difficulty chewing and a smile that “doesn’t look right.”
To correct this situation, we must often first attempt to orthodontically move any out of place teeth to their normal positions. This re-establishes the space needed for the missing teeth to be replaced, which we can then restore with prosthetic (artificial) teeth. If the permanent restoration of choice involves dental implants, we’ll usually need to wait until the completion of jaw development around early adulthood. In the mean time, we can use a retainer appliance to hold the teeth in their new positions with prosthetic teeth attached to fill the empty space for a better smile appearance in the interim.
The real issue is timing—beginning orthodontic treatment when appropriate to a person’s oral development, as well as completing the implant restoration when the mouth has matured sufficiently. There are other considerations such as bone volume, which may have diminished due to the missing teeth. At some point we may need to consider grafting to build up the bone sufficiently to support dental implants.
This all may entail a team approach by various specialties like orthodontics, periodontics and implantology. Working together and coordinating within a timely schedule, a mouth and smile marred by undeveloped teeth can be transformed.

Orthodontics shares a principle with the classic tug of war game: if you want things to move in the right direction you need a good anchor. Anchors help braces and other appliances apply constant pressure to misaligned teeth in the direction they need to go to correct a malocclusion (poor bite).
Orthodontic treatments work in cooperation with an existing oral mechanism that already moves teeth naturally in response to biting forces or other environmental factors. The key to this mechanism is an elastic tissue known as the periodontal ligament that lies between the tooth and the bone. Besides holding teeth in place through tiny attached fibers, the ligament also allows the teeth to move in tiny increments.
Braces’ wires laced through brackets affixed to the teeth exert pressure on them in the desired direction of movement –the periodontal ligament and other structures do the rest. To maintain that pressure we need to attach them to an “anchor”—in basic malocclusions that’s usually the back molar teeth.
But not all malocclusions are that simple. Some may require moving only certain teeth while not moving their neighbors. Younger patients’ jaws and facial structures still under development may also need to be considered during orthodontic treatment. That’s why orthodontists have other anchorage methods to address these possible complications.
One example of an alternate anchorage is a headgear appliance that actually uses the patient’s skull as the anchor. The headgear consists of a strap running around the back of the head and attached in front to orthodontic brackets (usually on molar teeth). The pressure it exerts can trigger tooth movement, but it can also help influence jaw development if an upper or lower jaw is growing too far forward or back.
Another useful anchorage method is a tiny metal screw called a temporary anchorage device (TAD) that is implanted into the jawbone above the teeth through the gums. Orthodontists then attach elastic bands between implanted TADs and specific braces’ brackets or wires to exert pressure on certain teeth but not others with pinpoint accuracy. After treatment the TADs can be easily removed.
Using these and other appliances allows orthodontists to customize treatment to an individual patient’s particular malocclusion. With the right anchor, even the most complex bite problem can be transformed into a beautiful and healthy smile.

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.
If you press your tongue against your teeth, unless something is badly wrong they won't budge. In fact, your teeth are subjected to a fair amount of pressure each day as you chew and eat, and yet they remain firmly in place.
But there's a deeper reality—your teeth do move! No, it's not a paradox—the gum and bone tissues that hold your teeth in place allow for slight, imperceptible changes in the teeth's position. Their natural ability to move is also the basis for orthodontics. Here are 3 more facts you may not know about your teeth's natural ability to move.
Teeth are always on the move. Teeth are held firmly within the jawbone by an elastic gum tissue called the periodontal ligament and a thin layer of bony-like material called cementum. In response to pressure changes, though, the bone dissolves on the side of the teeth in the direction of pressure and then rebuilds behind it, solidifying the teeth's new position, a process that happens quite slowly and incrementally. And it will happen for most of us—some studies indicate more than 70% of people will see significant changes in their bite as they age.
Orthodontics works with the process. Orthodontic appliances like braces or clear aligners apply targeted pressure in the direction the orthodontist intends the teeth to move—the natural movement process does the rest. In the case of braces, a thin metal wire is laced through brackets bonded to the front of the teeth and then anchored, typically to the back teeth. The orthodontist incrementally tightens the wire against its anchors over time, encouraging tooth movement in response to the pressure. Clear aligners are a series of removable trays worn in succession that gradually accomplish the same outcome.
Watch out for the rebound. That nice, straight smile you've gained through orthodontics might not stay that way. That's because the same mechanism for tooth movement could cause the teeth to move back to their former positions, especially right after treatment. To avoid this outcome, patients need to wear a retainer, an appliance that holds or "retains" the teeth in their new positions. Depending on their individual situations and age, patients may have to wear a retainer for a few months, years or from then on.
