Most people who grind their teeth have no idea they do it — it happens at night, quietly wearing enamel flat. Here is what causes bruxism, the signs to look for in the mirror and in the morning, and how a custom night guard protects your smile.
The Habit Most People Do Not Know They Have
Some of the most worn teeth we see at Shuster Dent belong to patients who are convinced they take excellent care of their smile — and they usually do. What they do not know is that for a few minutes each night, often without ever waking, they are clenching and sliding their teeth against one another with a force far greater than chewing ever requires. Dentists call this bruxism, and it is one of the most common problems we diagnose in people who never suspected a thing.
Bruxism comes in two forms. Awake bruxism is the daytime clenching many of us do while concentrating, sitting in traffic, or working through a difficult email — usually a steady squeeze rather than a grind. Sleep bruxism happens during sleep, is often rhythmic and audible, and is entirely outside your conscious control. The two have different triggers and are managed differently, which is why the first thing we try to work out is which one you have.
Why People Grind
There is rarely a single cause. Stress and anxiety are the most familiar contributors, and many patients notice their jaw feels tighter during a demanding stretch at work. But grinding is not purely psychological. Sleep bruxism is closely linked to disrupted sleep — in particular to sleep-disordered breathing such as obstructive sleep apnoea, where grinding episodes tend to cluster around brief arousals from sleep.
Other factors fill in the picture: caffeine and alcohol in the evening, smoking, certain antidepressant and stimulant medications, and — less often than people assume — a bite where the teeth do not meet evenly. In children, grinding is common and frequently outgrown, so it is usually a matter of monitoring rather than treating. Because these causes overlap, we look at the whole picture rather than settling on one explanation.
The Signs Worth Noticing
Most people learn they grind either from a partner who hears it or from us at a routine check-up, where the wear pattern is unmistakable. Between visits, these are the clues worth paying attention to:
- A dull headache around the temples, most noticeable on waking
- Jaw muscles that feel tired, tight, or sore first thing in the morning
- Teeth that look flattened, chipped, or shorter than they used to be
- Growing sensitivity to hot and cold as the enamel thins
- Clicking, locking, or aching in the jaw joint just in front of the ear
- A ridged line along the inside of the cheek, or scalloped edges on the tongue
- A partner who mentions hearing grinding during the night
What Grinding Actually Does to a Tooth
Chewing produces a moderate, well-distributed force for a few minutes at a time. Grinding concentrates a much heavier load onto a small number of teeth, repeatedly, and for far longer. Over the years that wears enamel flat, exposes the softer dentine beneath, and leaves teeth sensitive and prone to chipping. Cracks can develop, existing fillings can fracture, and crowns and implants take a beating as well.
The muscles and joints feel it too. Persistent clenching can leave the jaw muscles enlarged and tender, contribute to headaches and earache, and aggravate the temporomandibular joint. None of this happens overnight, which is exactly why it is worth catching early — the damage accumulates quietly, and enamel does not grow back.
How We Approach Treatment
Our aim is twofold: protect the teeth from further damage, and reduce the grinding itself wherever possible. A custom-made night guard is the mainstay of protection. Unlike the soft, boil-and-bite versions sold in pharmacies, a guard made from an impression of your own teeth fits precisely, spreads the load evenly, and absorbs the wear that would otherwise fall on your enamel.
Alongside the guard, we look at what can realistically be changed:
- Reviewing evening caffeine, alcohol and nicotine, all of which fragment sleep
- Screening for signs of sleep apnoea and referring on where it seems likely
- Simple daytime awareness — noticing a clenched jaw and letting the teeth rest slightly apart
- Stress-management approaches, physiotherapy, or gentle jaw exercises where muscle tension dominates
- Adjusting the bite or replacing worn restorations when they are clearly contributing
- Rebuilding already-damaged teeth once the grinding itself is under control
Let Us Take a Look
That last point matters more than it sounds. We deliberately restore worn teeth after protection is in place rather than before, because new dental work placed under an unmanaged grinding habit rarely lasts as long as it should. Bruxism is easy to overlook and generally straightforward to manage once it has been identified — a short examination is usually all it takes, since the wear on your teeth tells us a great deal and a few questions about your sleep and your mornings fill in the rest.
If you wake with a tight jaw or a headache, if a partner has mentioned the noise, or if your teeth simply look shorter than they once did, come and see us at our Haifa clinic. We will look carefully, explain plainly what we find, and put together a plan that protects your teeth for the long run. Book a visit with Shuster Dent — your jaw will thank you.
