Bruxism — the clinical term for grinding and clenching your teeth — affects a huge number of people, and a lot of them don't know they have it. The grinding often happens during sleep, silently generating enormous force on the teeth and jaw night after night. Over time, that force does real damage. The key is catching it before it costs you — and that starts with knowing the signs.
How to Tell If You Grind Your Teeth
Since it mostly happens while you're asleep, bruxism is usually spotted by its effects rather than the act itself. Watch for:
- A sore jaw or facial muscle tenderness, especially in the morning.
- Dull morning headaches — a classic sign.
- Teeth that look worn, flattened, or chipped, or are becoming more sensitive.
- Increased tooth sensitivity as enamel wears away.
- Aching or tired jaw muscles, or pain that feels like an earache.
- Disrupted sleep — yours or your partner's, who may actually hear the grinding.
Your Dentist Often Spots It First
Dentists can frequently see the characteristic wear patterns grinding leaves on teeth during a routine exam — often before you're aware anything's wrong. It's one more reason regular checkups matter: we can catch bruxism early, while it's still just a habit to manage and not damage to repair.
Why Grinding Is Actually Harmful
It's easy to dismiss grinding as harmless, but the forces involved are significant, and over time they add up:
- Worn and flattened enamel — the protective outer layer grinds away.
- Chipped, cracked, or loosened teeth — serious damage that can require major repair.
- Damaged dental work — fillings and crowns take a beating.
- Increased sensitivity — as enamel thins, hot and cold reach the nerve more easily (see sensitive teeth).
- Jaw pain, headaches, earaches, and jaw-joint problems.
- Disrupted sleep for you or your partner.
Because grinding happens during sleep and builds gradually, the damage accumulates before you notice — and advanced wear or a cracked tooth can mean crowns or other significant treatment. Catching and managing it early is far easier and cheaper than repairing the damage later.
The Fix: A Custom Night Guard
The most common and effective way to manage bruxism is a night guard — a custom-fitted appliance worn over your teeth while you sleep. It works simply but powerfully: it creates a protective barrier so the grinding forces act on the guard instead of wearing down and cracking your natural teeth. For many people, it also reduces jaw strain and the soreness and headaches that come with it.
Why custom beats over-the-counter
You can buy generic night guards at the drugstore, but a professionally made custom guard from a dentist fits better, is more comfortable, and lasts longer. That matters more than it sounds: a poorly fitting guard is uncomfortable (so you won't wear it) and less effective. A custom guard is molded to your teeth, so it does its job without being a nuisance.
One honest point: a night guard protects your teeth and manages symptoms — it doesn't cure the underlying habit. Grinding is often linked to stress, so addressing contributing factors can help too. But for protecting your teeth from damage, a custom guard makes a significant difference for most people.

Frequently Asked Questions
How do I know if I grind my teeth at night?
Since it happens during sleep, bruxism is usually detected by its signs rather than the act. Watch for a sore jaw, facial muscle tenderness, or dull headaches — especially in the morning — plus teeth that look worn, flattened, chipped, or increasingly sensitive. You might also notice aching or tired jaw muscles, earache-like pain, or disrupted sleep, and a partner may hear the grinding. Dentists can often spot the characteristic wear patterns during an exam before you're aware of it, which is one reason regular checkups matter. Since grinding quietly damages teeth over time, it's worth evaluating if you notice these signs. We can check — call (919) 213-6447.
Why is grinding your teeth harmful?
Grinding and clenching generate significant force on the teeth and jaw, and over time that can wear down and flatten enamel, chip or crack teeth, loosen teeth, damage fillings and crowns, and increase sensitivity as enamel wears away. Beyond the teeth, chronic grinding can cause jaw muscle pain and fatigue, tension headaches, earaches, jaw-joint problems, and disrupted sleep. Because it often happens during sleep and builds gradually, damage can accumulate before you notice, and advanced wear or a cracked tooth can require crowns or other significant treatment. Catching and managing bruxism early protects your teeth and avoids that damage. We can help — call (919) 213-6447.
Does a night guard really help with teeth grinding?
Yes — it's one of the most effective, common ways to manage grinding and protect your teeth. A night guard is a custom-fitted appliance worn over the teeth during sleep that creates a protective barrier, so grinding forces act on the guard instead of your natural teeth, and it can reduce jaw strain, soreness, and headaches for many people. A professionally made custom guard fits better, is more comfortable, and lasts longer than a generic over-the-counter one — which matters, since a poor fit is uncomfortable or less effective. Note it protects teeth and manages symptoms rather than curing the habit, so addressing stress may help too. We can make a custom night guard — call (919) 213-6447.
