A mother came in with worn, flattened back teeth and asked whether it was too late to do anything about them. Two weeks later her eleven year old was in the same chair, and the wear pattern on his molars was starting in the same places.
That conversation only happened because we see both of them. If they had been split between a pediatric office and an adult practice, nobody would have joined the dots for another decade.
Grinding is more familial than most people expect
Bruxism, which is the clinical name for grinding and clenching, runs in families often enough that a parent who grinds is a reason to look more closely at their children. It is not purely genetic. Airway, jaw development, stress and sleep quality all feed into it, and families share those too, which is part of the point.
What we can say is this. When one parent has the tell-tale wear, we check the children more carefully, and we find it more often than we would in a child whose parents show nothing. That is a useful thing to know and it is only knowable if we have the whole family’s records in one place.
What grinding actually looks like, at each age
In young children. Grinding at night is extremely common in children and most of it resolves on its own as the adult teeth come through. It is loud, it worries parents, and on its own it is usually not a problem. What we look for is grinding plus something else: snoring, mouth breathing, restless sleep, or dark circles that do not match how early the child went to bed. That combination is worth investigating.
In older children and teenagers. By this age the grinding that persists is more likely to matter. We look at the edges of the front teeth, the flat spots on the molars, and whether the enamel is starting to thin at the biting surfaces. We also ask about headaches, especially morning headaches, and jaw clicking.
In adults. By the time an adult notices it themselves, there is usually visible wear. Cracked molars, sensitivity that has no obvious cause, a jaw that aches on waking, and teeth that have quietly got shorter over twenty years. Most adults who grind do not know they grind. Their partner knows, or their dentist tells them.
The part that gets missed: breathing
This is the link that most general practices do not make, and it is the reason we screen for airway at every pediatric visit rather than only when a parent raises it.
A child who cannot breathe well through their nose will often grind. A narrow palate, crowded teeth, enlarged tonsils or adenoids, or a tongue tie can all restrict the airway, and grinding can be part of how the body responds during sleep. Treating the grinding on its own in that situation is treating the symptom.
The signs we look for are the ones parents rarely connect to teeth: snoring, sleeping with the mouth open, waking unrefreshed, bedwetting past the usual age, trouble concentrating at school, and restlessness at night. None of those is proof of anything on its own. Together, in a child who also grinds, they are worth a proper look.
Through our Sleep Better Charlotte program we assess and treat airway related issues in children from about age three, using palate expansion, growth guidance appliances and early orthodontics where they are genuinely needed. We are not trying to put every child into treatment. Most children who grind need nothing more than a review at their next cleaning.

What we do about it
For most young children, nothing. We note it, we check it at the next visit, and we tell you what would change our mind. Night guards are rarely appropriate for children with baby teeth because the jaw is still growing.
For children with airway signs, we investigate properly rather than fitting an appliance and hoping. That might mean imaging, it might mean a referral, and it might mean growth guidance if the palate is narrow.
For teenagers and adults with visible wear, a night guard is the first line and it works. It does not stop you grinding. It puts a replaceable piece of acrylic between your teeth so the wear happens to that instead of to your molars. A custom guard made from a scan of your teeth is a different object from the boil-and-bite version at the pharmacy, which tends to be bulky enough that people stop wearing it by week three.
For adults where the bite itself is the problem, the guard is a holding measure and the bite needs addressing. We will say so rather than selling you a guard every three years.
If you already grind and you are considering cosmetic work, this matters more than usual. Porcelain on the front of a tooth that is being ground down nightly will chip. Sorting the grinding first is not us delaying the fun part, it is the thing that makes the fun part last.
Stress gets blamed for all of it, and that is lazy
Ask most people why they grind and they will say stress. Sometimes that is right. Often it is the explanation people reach for because it is the only one they have heard, and it has the unfortunate effect of making grinding feel like a personality problem rather than a physical one you can do something about.
Stress is a genuine contributor in adults. It is a much weaker explanation in a six year old who snores.
The more useful question is what else is going on. How does this person breathe at night. How do their teeth meet. Is there a tooth sitting slightly high that the jaw is trying to work around. Are they on a medication known to increase clenching. Has anything changed recently in how they sleep.
We ask those because they point at something you can act on. Telling a patient to relax more does not.
What it costs to leave it
Worn teeth do not grow back, and that is the whole argument for dealing with this early.
A molar that has been ground flat over fifteen years is a candidate for a crown, not a filling. Front teeth that have lost two millimeters off the edge change how the whole smile reads, and rebuilding them is cosmetic work on top of restorative work. Enamel thinned at the biting surface means sensitivity that gets worse rather than better.
A custom night guard costs a small fraction of one crown. That comparison is the only argument for a guard we think is worth making, and it is a strong one.
Why seeing everyone in one place changes what we catch
Grinding is the clearest example, but it is not the only one.
Gum disease has a hereditary component, so a parent with a periodontal history changes how closely we watch their children’s gums. Jaw and airway patterns repeat across siblings. Enamel defects run in families. Even habits do, because children copy what they see at home, including how their parents brush and how their parents talk about the dentist.
None of this appears in a chart if your family’s records are sitting in three different buildings. We see a pattern because we are looking at the same family over years, and a pattern is what lets us say something useful before the damage is done rather than after.
What to do if you recognize any of this
If you grind, mention it at your next cleaning, and mention whether anyone else in the house does.
If your child grinds and sleeps badly, bring it up rather than waiting to be asked. It costs nothing to have us look, and an airway assessment is a conversation and an examination, not a commitment to treatment.
And if your family is currently split across different practices, seeing everyone in one place is worth more than the scheduling convenience. We can also talk about a custom night guard if the wear is already there, or look at teeth grinding alongside the jaw pain that often comes with it.
