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.

Somewhere around age 6, your child’s primary (baby) teeth will begin to give way to their permanent set. If all goes well, you’ll notice all the front teeth erupting in the right position: the top teeth slightly overlapping the bottom and all coming in without crowding.
Sometimes, though, the process doesn’t occur as it should and a bad bite (malocclusion) may develop. You can get a head start on treatment if you know what to look for. Here are a few problems for which you should see a dentist — or more likely an orthodontist — for a thorough evaluation.
Spacing problems. Teeth should normally come in right next to each other without a noticeable gap. But if you notice excessive space between the permanent front teeth especially, this may be an indication there’s a discrepancy in size between the teeth and the jaws. At the other end of the spectrum, if teeth on the same arch appear to overlap each other, this indicates crowding in which there’s not enough space for the teeth to erupt properly.
Bad bites. Malocclusions can take different forms. In an underbite, the front bottom teeth bite in front of the upper teeth. If there’s a noticeable gap between the upper and lower teeth when the jaws are closed, this is known as an open bite. Front teeth biting too far down over the lower teeth is a deep bite and could even include biting into the soft tissue of the hard palate. Cross bites can occur in either the front or back teeth: if in the front, some of the lower teeth will bite in front of the upper; if in the back, some of the lower teeth bite outside the upper rather than normally on the inside.
Abnormal eruptions. You should also be alert for protusions, in which the upper teeth or the jaw appears to be too far forward, or retrusions, in which the lower teeth or jaw appears to be too far back. You should also be concerned if permanent teeth erupt far from their normal position — this is especially likely if the primary tooth was also out of position, or was lost prematurely or not in the right order.
