Most people who grind their teeth at night have no idea they are doing it. There is no memory of it in the morning and no obvious damage in the mirror for years. Usually it is a partner who notices the sound, or a dentist who notices the wear.
Grinding and clenching, or bruxism to give it its clinical name, are common, and left alone they are one of the more expensive things that can happen to a healthy mouth. The good news is that the protection is simple and the damage is very preventable once someone has spotted it.
What Grinding and Clenching Actually Are
Grinding is sliding the teeth across each other. Clenching is holding them together hard without movement. Plenty of people do both, and clenching is the quieter of the two because it makes no noise at all.
Either can happen while you are awake, usually during concentration or stress, or during sleep, when you have no control over the force at all. Sleep is where the real damage happens, because the bite force available when you are not conscious is far higher than anything you would apply deliberately.
How to Tell If You Are Grinding or Clenching
You will not catch yourself at it. What you can notice is the pattern it leaves, and the symptoms tend to show up in the same few places.
A dull headache in the temples first thing in the morning is the most common clue, and it is frequently mistaken for something else entirely. A jaw that feels tired or tight on waking is another. Some people notice their jaw clicking, or an ache that spreads into the ear or down the neck.
Teeth themselves give it away too. Sensitivity to cold that has crept in without an obvious cause, front teeth that look shorter or flatter than they used to, or small chips along the biting edges. If you have a partner, disturbed sleep and an audible grinding noise are worth taking seriously rather than laughing off.
Why Grinding Matters More Than It Sounds
Enamel does not grow back. That is the entire problem in one sentence.
Years of grinding wears through the enamel to the softer dentin underneath, which wears far faster once exposed. Teeth become sensitive, then shorter, and the bite changes shape. Restoring a worn down bite is one of the larger pieces of dentistry there is, and it is entirely avoidable with a mouth guard that costs a fraction of it.
It Breaks Dental Work First
Crowns, veneers, bridges and fillings take the force of grinding or clenching before natural teeth do. Patients sometimes come in with a crown that has failed twice and assume the dentistry was poor. Frequently the dentistry was fine and the grinding was never addressed, so the replacement met the same force that broke the original. If a crown has failed on you more than once, grinding is one of the first things worth ruling out.
It Can Show Up in Your Gums
Constant excessive force does not help gum and bone that are already under strain. Grinding does not cause gum disease, but it is an unhelpful passenger alongside it, and both are worth treating rather than treating one and leaving the other. If your gums bleed or feel tender as well, raise it at the same appointment, because gum disease treatment is a separate job from protecting the enamel and the two are often needed together.
What Causes It
Honestly, often nobody can say for certain in an individual case. Stress and anxiety are strongly associated with it, and many people notice their grinding gets worse in demanding periods. Disturbed sleep and some medications are associated with it too.
A bite that does not meet evenly can be a factor, which is one of the things worth examining rather than assuming. What we can say is that a night guard protects your teeth whatever the underlying cause turns out to be, which is why it is usually the first step rather than the last.
What is a Night Guard?
A custom night guard is a thin appliance made to fit your teeth exactly, worn while you sleep. It does not stop you grinding. It puts a replaceable surface between your upper and lower teeth so that the guard absorbs the wear instead of your enamel.
That is the whole idea, and it is why the guard will eventually show wear itself. A guard that is visibly chewed after a couple of years has done exactly what it was made to do, and the results are the teeth underneath it still being the shape they started.
Custom Made Against Off the Shelf
You can buy a boil and bite mouth guard at a pharmacy, and for the price it is better than nothing in the short term. However, there are real differences worth knowing about before you rely on one long term.
A pharmacy guard is bulkier, which makes it harder to sleep in, and people who cannot sleep in a guard stop wearing it. It fits approximately rather than exactly, so it can move during the night. And because it is not made to your bite, it can hold your jaw in a position that creates its own aches.
A custom mouth guard is made from an impression or scan of your own teeth. It is thinner, it stays put, and it is built to let your jaw sit where it naturally wants to.
What the Appointment Involves
There is nothing uncomfortable in it. We examine your teeth and look specifically for wear patterns, check how your bite meets, and ask about headaches and jaw soreness. If a guard is the right answer we take a scan or an impression, and the guard is made to fit that.
When it is ready you come back to have it fitted and adjusted so it sits comfortably. Small adjustments at that visit are normal and are the reason a custom guard works better than one you fit yourself.
Getting Used to Wearing It
Most people take a few nights to adjust. Put it in a little before bed rather than as the light goes off, so it stops feeling novel while you are still awake. If it is still uncomfortable after a week, come back and let us adjust it rather than leaving it in a drawer.
Looking After It
Rinse the guard in cool water each morning and let it dry fully before it goes in its case because a damp closed case is a good home for bacteria. Brush it gently with a soft brush, and keep it away from hot water, which distorts it.
Bring the guard with you to your checkups. We can look at the wear on it, which tells us something useful about how hard you are grinding and whether anything is changing.
What Else Can Help
A guard protects your teeth but does not treat the cause. Some patients find genuine benefit in addressing sleep quality, in managing stress in whatever way works for them, and in cutting back caffeine and alcohol late in the evening.
If jaw pain is significant rather than mild, say so, because persistent jaw joint pain deserves proper assessment rather than a guard alone. And if a tooth cracks or you wake with severe pain, that is worth an emergency appointment rather than waiting for a routine slot.
Frequently Asked Questions
How do I know if I grind my teeth if I live alone?
Look for the pattern rather than the act. Morning headaches in the temples, a tired jaw on waking, new cold sensitivity, or front teeth that look flatter than they did. A dentist can also see wear facets on the biting surfaces that are fairly unmistakable.
Will a night guard stop me grinding?
No, and no guard claims to. It protects your teeth from the force. That is a different thing from stopping the habit, and it is the part that saves your enamel.
How long does a custom mouth guard last?
It depends on how hard you grind. Some people wear through one noticeably faster than others. Bring it to your checkups and we will tell you when it needs replacing rather than leaving you to guess.
Do children grind their teeth?
Many children do, and in children it often resolves on its own as the adult teeth come through. It is still worth mentioning at a checkup so we can keep an eye on the wear.
Can I wear a guard if I have crowns or bridges?
Yes, and it is often more important if you do. Dental work tends to take the force before natural teeth, so protecting it is usually worth the visit.
Does it affect my breathing at night?
A properly fitted guard should not. If you snore heavily or have been told you stop breathing in your sleep, tell us, because that is a separate issue that deserves its own assessment.
