Night Guards for Teeth Grinding: Toronto Cost Guide
If you're grinding your teeth at night, a custom night guard is the simplest way to protect them, and in Toronto a professional one usually runs about $300 to $600. It's a thin, fitted appliance you wear while you sleep, and it works like a bumper: the grinding wears down the guard instead of your enamel, your crowns, or your fillings. I've practised in Bloor West Village for about 25 years, and grinding is one of those problems people don't know they have until something cracks. Here's how to spot it, what it damages, and what a guard really does for you.
Do you grind your teeth without knowing it?
Here's the strange part. Most people who grind have no idea they're doing it. Bruxism is the involuntary clenching, grinding, or gnashing of teeth (Canadian Dental Association). A lot of it happens while you're asleep, so you're not awake to catch it.
It's more common than you'd guess. A 2024 meta-analysis put the global rate of bruxism at about 22%, with sleep bruxism around 21% and awake clenching around 23% (PMC). North America sits higher than most regions, with sleep bruxism around 31% (PMC). So if you think one in four or five adults is grinding, you're about right.
So how do you find out? Often someone else tells you. If you grind while sleeping, it's not uncommon for a partner, spouse, or parent to hear it first (Canadian Dental Association). The other tell is your own morning: aching teeth or jaws when you wake up or eat breakfast, plus headaches (Canadian Dental Association). If your jaw is tired before your day even starts, that's worth a look.
What does grinding actually destroy?
Wait, isn't grinding just a bad habit? It's more than that. It's a slow wrecking ball for your teeth and any dental work you've paid for.
Prolonged grinding or clenching can lead to cracked or broken teeth, broken crowns and fillings, and a higher risk of gum problems (Canadian Dental Association). In 25 years I've seen flattened molars, chipped front teeth, and fillings that keep popping out for no obvious reason. Grinding is usually the reason.
Here's the part that stings. If you've invested in cosmetic or restorative work, grinding chews right through it. A brand-new porcelain crown can crack under nightly clenching. So can veneers or bonding. Even a fresh whitening result doesn't mean much when the biting edges are wearing flat. Worn enamel also leaves teeth more sensitive to hot and cold, which is one of the causes I cover in our tooth sensitivity guide. Protecting the smile you already paid for is a big reason people finally get a guard.
How much does a night guard cost in Toronto?
Shopping around on price? Fair. A custom night guard from a Toronto dental office generally lands between $300 and $600 in my experience across the city. That's a ballpark from my chair, not a set price.
A few things move that number: whether it's a soft, hard, or dual-layer guard, how much adjusting your bite needs, and the individual office. Ontario dentists aren't required to follow any fee schedule. They set their own fees, so a dentist's fees may fall above or below the provincial guide (Ontario Dental Association). The only real number is the one you get after an exam.
Many extended health plans cover a night guard, at least in part, since it's a recognized dental appliance. Coverage and annual maximums vary, so check your booklet or bring it in and we'll help you read it.
Custom guard vs boil-and-bite vs drugstore: which is worth it?
Most people think a $30 drugstore guard and a custom one do the same job. What gives? They don't. The difference is fit, and fit is the whole ballgame with a night guard.
Here's the honest comparison I give patients.
| Type | Rough cost | Fit and comfort | How long it lasts |
|---|---|---|---|
| Drugstore stock guard | About $15 to $30 | One-size, bulky, often falls out | Months |
| Boil-and-bite (OTC) | About $20 to $50 | Molded at home, better but still loose | Months to a year |
| Custom (dental office) | About $300 to $600 | Made from a scan of your teeth, snug | Several years with care |
Does a night guard stop the grinding, or just protect the teeth?
Here's the myth worth clearing up. A night guard doesn't cure grinding. It protects your teeth from it, and that's a different thing.
What a custom guard does well is act as a physical barrier. Your dentist may recommend one because it helps even out the pressure across the jaw and creates a barrier between your upper and lower teeth to protect them from damage (Canadian Dental Association). In plain terms, the guard takes the wear so your enamel doesn't.
Does it stop the grinding itself? The research there is honestly mixed. A 2021 systematic review found insufficient evidence to say occlusal splints reduce the grinding over no treatment (PubMed). So I don't oversell it. A guard is armour, not a cure. Whatever's driving the grinding, often stress, is still worth addressing alongside it.
Clenching, stress, and your jaw
Are you clenching during the day too? Plenty of people do, and never notice. Clenching tends to happen while you're tense and awake, at a computer, in a meeting, or stuck in traffic.
Stress is a real player here. The underlying causes of grinding or clenching can be aggravated by elevated stress or anxiety (Canadian Dental Association). That's why a guard is only half the answer. If your jaw muscles ache, your temples throb, or your jaw clicks, the grinding may be straining the joint too. A quick daytime habit helps: keep your teeth apart unless you're chewing. Lips together, teeth slightly open. Try that for a week and notice how often you were clenched without knowing.
Getting fitted for a night guard in Bloor West Village
What actually happens if you come in? No mystery. We start with a look at your teeth for the tell-tale wear, flattened tips, tiny chips, worn edges. If a guard makes sense, we take a scan or impression, and the lab builds a guard shaped to your bite. You come back, we check the fit and adjust it so it feels like nothing, and you wear it at night.
Some days the schedule pushes me, and even then we take the time to get the bite right, because a guard that doesn't fit is a guard you'll stop wearing. If you're waking up with a sore jaw, or a partner has mentioned the sound, come in and let us take a look before a tooth cracks.
Frequently Asked Questions
Q: How much does a custom night guard cost in Toronto? A custom night guard from a Toronto dental office generally runs about $300 to $600, based on what I see across the city. The type of guard and how much bite adjustment it needs move the price. Those are ballparks, not quotes. Ontario dentists set their own fees (Ontario Dental Association), so only an exam gives a real number. Many dental plans cover part of it.
Q: Are drugstore or boil-and-bite night guards good enough? They're better than nothing, but they don't fit as well. A stock or boil-and-bite guard is bulkier and looser, so it's less comfortable and people often stop wearing it. A custom guard is made from a scan of your own teeth, stays put, and lasts several years. Comfort matters, because a guard only protects your teeth on the nights you wear it.
Q: How do I know if I grind my teeth at night? Often someone tells you first. If you grind while sleeping, a partner or family member may hear it before you notice (Canadian Dental Association). Watch for aching teeth or jaws when you wake up, plus morning headaches (Canadian Dental Association). Your dentist can also spot the wear pattern during a checkup.
Q: Does a night guard stop me from grinding? No, and that's the honest answer. A guard protects your teeth by creating a barrier and evening out the pressure (Canadian Dental Association), but a 2021 review found insufficient evidence that it reduces the grinding itself (PubMed). Think of it as armour for your teeth while you work on whatever's driving the grinding, often stress.
Q: Can grinding damage my crowns, veneers, or fillings? Yes. Prolonged grinding can lead to cracked or broken teeth and broken crowns and fillings (Canadian Dental Association). If you've paid for a crown or cosmetic work, a night guard helps protect that investment from nightly clenching.
Q: How long does a custom night guard last? With normal care, a custom night guard usually lasts several years. How long depends on how hard you grind and how well you clean and store it. Rinse it, brush it gently, and keep it dry in its case. Bring it to your checkups so we can check it for wear and make sure it still fits.
