Night Guards in Oakville – Stop Teeth Grinding Damage

Signs You Are Grinding Your Teeth

Most people who grind have no idea they do. The habit happens during sleep, so the evidence is indirect, and it is usually a partner who hears it first or a dentist who spots it on the teeth. The signs worth paying attention to are a dull headache or tightness at the temples on waking, jaw or ear ache first thing in the morning that eases as the day goes on, teeth that feel sensitive to cold with no obvious cavity, front teeth that have become shorter or flatter than they used to be, tiny chips along the biting edges, a tooth that suddenly aches when you bite on it, fillings or crowns that keep fracturing or coming loose, a ridge of thickened skin along the inside of your cheek at the level of your teeth, or scalloped indentations along the edge of your tongue.

Clenching during the day is a separate and very common pattern, and it is easier to catch. If you notice your teeth touching while you concentrate, drive, or read a screen, that is clenching. Teeth should rest slightly apart with the tongue on the palate; they only need to touch when you swallow or chew.

What Grinding Does to Your Teeth

The forces involved are the reason this matters. Normal chewing generates a fraction of what the jaw muscles can produce, and nocturnal grinding removes the reflexes that limit force while you are awake. Sustained over years, that produces a predictable sequence of damage.

Enamel wears away first, flattening the cusps of the back teeth and shortening the front ones. As the harder outer layer thins, the softer dentine underneath is exposed, which is both yellower in appearance and far more sensitive – this is why grinders often notice their teeth looking darker as well as shorter. Small vertical cracks develop in the enamel, and some of them propagate. Old fillings become surrounded by cracked tooth and eventually a cusp fractures off, which is the point at which a filling becomes a crown, and occasionally the point at which a tooth becomes unsaveable. Teeth can be loosened as the ligament around the root is repeatedly overloaded, and the gum can recede at the neck of the tooth where flexing concentrates.

The jaw joints and muscles take their share too, which is where morning headache, limited opening and clicking come from. And cosmetically, worn short front teeth are one of the main things that makes a smile look aged – a great many smile makeovers are really the repair of two decades of grinding.

None of this is reversible. Enamel does not grow back. That is the entire argument for a guard: it does not stop you grinding, but it makes the grinding harmless.

Why People Grind

Bruxism is not one condition with one cause, which is why we ask about more than your teeth. Stress and anxiety are the most commonly identified trigger, and many people can date the onset of their grinding to a particular period in their life. Sleep-disordered breathing is the one worth taking seriously: grinding is strongly associated with obstructive sleep apnoea, and if you also snore heavily, wake unrefreshed, or have been told you stop breathing in your sleep, we will raise the possibility of a sleep assessment rather than simply fitting a guard over the problem.

Beyond that, caffeine and alcohol in the evening both increase night-time grinding, as does nicotine. Certain medications, particularly some SSRIs and stimulants, list bruxism as a side effect. Reflux is associated with it. And a bite where the teeth do not meet evenly can contribute, which is one reason we check how your teeth come together rather than only looking at the wear.

We mention all of this because a guard treats the consequence, not the cause. Protecting the teeth is the urgent part, but if there is a cause that can be addressed, it is worth knowing about.

How a Custom Night Guard Works

A night guard is a shell that covers the biting surfaces of one arch, usually the upper. It does three things. It puts a layer of hard acrylic between the opposing teeth so that any wear happens to the appliance rather than to enamel. It spreads load across all the teeth at once instead of letting one or two take a concentrated hit, which is what protects crowns, veneers and heavily filled teeth. And by slightly separating the jaws, it reduces the mechanical advantage of the closing muscles, which is why many people report less morning jaw ache within a week or two.

What it does not do is stop the habit. You will still grind; the guard simply makes it a non-event. Some people find the guard itself wears down over a few years, which is exactly the point – that wear would otherwise have been on their teeth.

Custom, Boil-and-Bite, or an Online Kit?

This is the question we are asked most, and it deserves a straight answer rather than a sales pitch.

Boil-and-bite guards from a pharmacy

These are better than nothing in the very short term. The problems are that they are bulky, which makes them uncomfortable enough that most people abandon them within a fortnight; they are made of soft thermoplastic, which for a determined grinder can actually encourage chewing rather than discourage it; and because they do not fit precisely, they can allow teeth to shift slightly over months of wear. They also cover unevenly, so load is not properly distributed.

Online mail-order impression kits

The laboratory work behind these is often perfectly good. The weak point is the impression, because taking an accurate one of your own teeth without training is genuinely difficult, and a guard built on a distorted impression fits badly. The bigger issue is that nobody examines you. A guard fitted over an undiagnosed cracked tooth, active decay or gum disease traps the problem underneath it, and grinding is quite often accompanied by exactly those things.

A custom guard made at the practice

We take a precise impression or digital scan, record how your jaws actually meet, and have the guard made in a dental laboratory to a thickness and material chosen for how hard you grind. It is then fitted and adjusted in your mouth so that contact is even across every tooth – the adjustment stage is what makes the difference between a guard you tolerate and a guard you forget you are wearing. It costs more, it lasts years rather than months, and it is examined and adjusted at your check-ups.

Our honest position: if the cost of a custom guard is genuinely out of reach right now, a pharmacy guard used carefully is better than leaving your teeth unprotected, and we would rather tell you that than see nothing done. But if you have crowns, veneers, bonding or a history of cracked teeth, a custom guard is not a luxury – a single fractured molar costs several times more to fix.

Types of Night Guard

Hard acrylic is the standard choice for moderate to heavy grinders. It is durable, it does not encourage chewing, and it distributes force best. It takes a few nights to get used to.

Soft guards are more comfortable immediately and are appropriate for light grinders and for people whose main problem is clenching rather than grinding. They wear through faster and are not the right choice for someone who grinds hard.

Dual-laminate guards have a soft inner surface against the teeth and a hard outer surface. For many patients this is the best compromise, and it is what we most often recommend.

Upper or lower? Upper is more common and generally more stable. A lower guard is often better tolerated by people who gag easily, and is the choice if you have extensive upper restorations we want left untouched.

One thing we will steer you away from is a guard covering only the front teeth. These are sold online and they do reduce noise, but leaving the back teeth free to move means the bite can change over months of use, and that is a difficult and expensive problem to reverse. Full-arch coverage is the safe design.

Getting Your Night Guard: Two Appointments

Appointment one

We examine your teeth and record the wear, check the jaw joints and muscles for tenderness and clicking, measure how far you can open, look at how your teeth meet, and take x-rays if there is any suggestion of a crack or of decay under an existing filling. If a tooth needs repairing first, we deal with that before making a guard, because a guard made now would not fit once the tooth is restored. Then we take the impression or digital scan and the bite record, and we discuss the material and thickness.

Appointment two

Usually one to two weeks later. We fit the guard, check it seats fully without rocking, and adjust the biting surface until contact is even across the arch – this is done with you biting on marking paper, and it typically takes several small adjustments. We show you how to insert and remove it, and how to clean it. Come back if it feels high on one side or if a tooth is tender in the morning; that is a five-minute adjustment, not something to put up with.

Wearing It and Looking After It

Expect the first three or four nights to feel odd. Increased saliva, awareness of bulk, and occasionally taking it out in your sleep without remembering are all normal and all settle. Wearing it for an hour in the evening while watching television for the first few days speeds up the adjustment considerably.

Rinse it and brush it with a soft brush and cool water each morning – not toothpaste, which is abrasive and will dull and scratch the acrylic. Let it dry completely before putting it in its case, because a damp guard in a closed box grows bacteria and develops a smell. Never use hot water, never leave it on a windowsill or in a car, and never put it in the dishwasher: heat warps acrylic permanently and a warped guard cannot be adjusted back. Soak it in a proprietary appliance cleaner once a week. Keep it well away from pets, who find them irresistible – this is by some distance the most common reason we remake them.

Bring it to every check-up. We check the fit against any new fillings, look at how it is wearing, and adjust it. A well-cared-for guard typically lasts three to five years, less if you grind heavily, and the wear on it is a useful record of how much force your teeth are being spared.

Jaw Pain, Clicking and TMJ Problems

A guard helps many people with jaw pain, but jaw pain is not always a grinding problem and we do not want to fit an appliance and call it treated. If your joint clicks, locks, or if you cannot open fully, we assess the joint properly. Conservative measures do most of the work: a soft diet for a few weeks, cutting food small, avoiding chewing gum and biting nails, warm compresses, gentle jaw exercises, and consciously keeping the teeth apart during the day. Anti-inflammatory pain relief helps in the acute phase.

Where the bite is clearly uneven and one or two teeth are taking all the load, a small adjustment can make a disproportionate difference. Where the underlying problem is that the teeth do not meet properly at all, aligning them may be the more durable answer than a guard worn indefinitely. And where the pain is severe, persistent, or the joint is locking, we refer you on rather than persevering. Tell us what you have noticed, including whether it is worse in the morning – morning-dominant pain points to night-time grinding, while pain that builds through the day points to daytime clenching, and the two need different advice.

Sports Mouthguards

A night guard and a sports mouthguard are different appliances and are not interchangeable. A sports guard is thicker, made of resilient material, and designed to absorb a single large impact rather than repeated grinding; a night guard is thinner and harder and would shatter or transmit the blow.

Hockey, basketball, soccer, rugby, martial arts and skateboarding are where we see dental injuries in Oakville, and a knocked-out or fractured front tooth in a teenager is a lifetime of dentistry. A custom sports guard costs a fraction of restoring one tooth, and unlike a boil-and-bite version it is thin enough to speak and breathe through, which is the difference between a guard that is worn and one that lives in the kit bag. We remake them as children grow. If you or your child plays a contact sport and wears braces, tell us – a guard designed over brackets is essential and is made differently.

Cost and Coverage

A custom night guard is a single laboratory-made appliance with a fitting and adjustment appointment, and we will give you the exact figure before we take any impressions. Adjustments afterwards are part of the treatment, not extras. A custom sports guard costs less than a night guard, and there is a discount when several are made for the same family at once.

Most private dental plans cover occlusal guards, commonly at 50 to 80%, but two clauses catch people out and both are worth checking first: many policies allow only one guard every three to five years, and some require evidence of clinical need such as documented wear or a diagnosis of bruxism. We will submit a predetermination with the clinical justification so you have your insurer’s written answer before you commit. Guards for a diagnosed grinding problem may also be covered for eligible patients under the Canadian Dental Care Plan subject to pre-authorisation, which we handle for you.

Night Guards in Oakville – Common Questions

How do I know if I grind my teeth?

The reliable signs are morning jaw or temple ache, flattened or chipped biting edges, unexplained cold sensitivity, and restorations that keep failing. We can usually tell from the wear pattern on your teeth at an examination, even if nobody has ever heard you grinding.

Will a night guard stop me grinding?

No. It protects your teeth from the grinding and usually reduces muscle ache, but the habit itself continues. Addressing stress, evening caffeine and alcohol, and any sleep-breathing problem is what reduces the grinding.

Is a custom guard really better than a pharmacy one?

Yes, on fit, comfort, durability and load distribution – and consequently on whether you keep wearing it. If cost is prohibitive right now, a pharmacy guard is better than nothing, but it is a stopgap.

How long does it take to get one?

Two appointments about one to two weeks apart. If a tooth needs repairing first, that is done before the impression.

Does it hurt or feel uncomfortable?

It is not painful. It feels bulky for the first few nights and produces extra saliva initially. Most people stop noticing it within a week. Persistent soreness in one tooth means it needs adjusting, so come back.

Upper or lower guard?

Upper is the usual choice and is generally more stable. Lower suits people who gag easily or who have extensive upper restorations.

How long will it last?

Typically three to five years, shorter for heavy grinders. Bring it to your check-ups so we can monitor the wear and adjust it around any new fillings.

Can I use my night guard for sport?

No. A night guard is thin and hard and is not designed to absorb impact. Sports guards are a different appliance and we make those too.

Can children have a night guard?

Grinding in children is common and usually harmless, and it often stops once the adult teeth come through, so we rarely make guards for young children. If there is genuine wear on permanent teeth we will consider one, remade as the mouth grows. See our kids dentistry page.

Will insurance pay for it?

Most plans contribute, often 50 to 80%, usually with a replacement limit of one every three to five years. We send a predetermination with the clinical justification so you know the payable amount in advance.

I already have worn or chipped front teeth. What now?

Two separate things: protect what is left with a guard, and decide whether to rebuild what has gone. Worn edges are often restored with composite bonding in a single visit, and heavily damaged teeth may need veneers or crowns. Rebuilt teeth without a guard will simply be worn down again, so the guard comes as part of the plan rather than as an optional extra.

Can grinding be related to sleep apnoea?

There is a well-recognised association. If you snore heavily, wake unrefreshed, or have been told you stop breathing in your sleep, we will raise a sleep assessment with you, because treating that can reduce the grinding as well as being important in its own right.
