Around ages 6 to 8, a child's primary teeth will begin to loosen to make way for their permanent teeth. If all goes well, the new set will come in straight with the upper teeth slightly overlapping the bottom.
But sometimes it doesn't go that well: a child may instead develop a poor bite (malocclusion) that interferes with normal function. If we can detect the early signs of a developing malocclusion, however, we may be able to intervene and lessen its impact. You as a parent can play a vital role in this early detection.
The first thing you should be watching for is teeth spacing.Â Normal teeth come in straight with a slight gap between them. But there are two abnormal extremes to look for: teeth having no space between them or crowded together in a crooked, haphazard manner; or they seem to have too much space between them, which indicates a possible discrepancy between the teeth and jaw sizes.
You should also notice how the teeth come together or “bite.” If you notice the lower front teeth biting in front of the upper (the opposite of normal) it may be a developing underbite. If you see a space between the upper and lower teeth when they bite down, this is a sign of an open bite. Or, if the upper front teeth seem to come down too far over the lower, this could mean a deep bite: in extreme cases the lower teeth actually bite into the roof of the mouth behind the upper teeth.
You should also look for crossbites, in which the teeth in one part of the mouth bite abnormally in front or behind their counterparts, while teeth in other parts bite normally. For example, you might notice if the back upper teeth bite inside the lower teeth (abnormal), while the front upper teeth bite outside the lower front teeth (normal).
The important thing is to note anything that doesn't look right or seems inconsistent with how your child's teeth look or how they function. Even if you aren't sure it's an issue, contact us anyway for an examination. If it really is a developing bite problem, starting treatment now may lessen the extent and cost of treatment later.
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.
In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.
When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”
Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.
There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.
By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.
So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.
