Has a dentist ever told you that you grind your teeth, even though you were sure you didn't? It's one of the more common surprises in a routine exam. Grinding or bruxism happens during sleep, which means most people have no idea it's occurring until a dentist points out the evidence.
At Clove Dental, we see this often. Here's why a night guard gets recommended, what grinding actually does to your teeth over time and what a dentist in Camarillo is really looking at when they bring it up.
Grinding doesn't require you to be aware of it. It happens during sleep, often during specific sleep stages and the person doing it has no memory of it the next morning. A partner might mention hearing it but plenty of people grind silently or sleep alone and never get that feedback.
Dentists look for physical evidence instead of relying on a patient's own awareness. Worn, flattened edges on teeth, small fractures and certain patterns of tooth sensitivity are all signs that point toward grinding, regardless of whether the patient has ever noticed anything themselves.
Grinding forces are significant, many times stronger than the forces involved in normal chewing. Applied repeatedly over months and years during sleep, these forces gradually wear down the enamel on biting surfaces, creating a flattened or shortened appearance to the teeth that's easy to miss without a trained eye.
Small cracks can develop in the enamel long before they cause any sensation. Fillings and crowns can loosen or fracture under repeated grinding pressure. None of this hurts in the early stages which is exactly why the damage often progresses for years before a patient notices anything is wrong.
A few specific findings tend to stand out during an exam. Flattened or shortened front teeth, especially compared to how they likely looked years earlier, are a common clue. Small chips along biting edges that don't correspond to any specific injury point toward repeated grinding wear rather than a single event.
Dentists also look at the cheek and tongue tissue, since grinding and clenching can leave subtle scalloped or rippled patterns along the edges from repeated pressure against the teeth. None of these signs are something most patients would think to check for themselves which is why they're raised for the first time during a routine visit.
Store-bought guards offer some protection, but they come with real limitations. A generic, one-size-fits-all design rarely matches the exact shape of an individual's teeth and bite which can mean uneven coverage, discomfort or a guard that shifts out of place during sleep.
A custom-fitted night guard is made from an impression or scan of your specific teeth which means consistent coverage and a fit that stays in place through the night. It's also built from materials calibrated to the patient's grinding intensity, something a generic store option simply can't account for.
The damage accumulates gradually, then becomes more noticeable. Enamel wear that starts subtly can progress to visibly shorter teeth, increased sensitivity and a higher risk of cracks that eventually require a crown to repair. Existing fillings or crowns are also more likely to fail prematurely under sustained grinding pressure.
Jaw-related symptoms often occur in a similar manner, with the symptoms being occasional stiffness, and possibly more chronic symptoms or joint problems if the grinding habit is not addressed.
Not directly. A night guard will not cure the habit of grinding associated with stress, sleep habits or other issues. What it does is to shield the teeth and cut down on the tension of the jaws during that habit, and so prevent the cumulative damage that would accumulate over time.
For some patients, addressing the underlying cause, such as stress management or evaluating sleep quality, can reduce grinding frequency. The night guard works alongside that broader picture as a protective measure, not a cure on its own.
Teeth grinding is easy to miss simply because it happens while you're asleep. A dentist in Camarillo is the first person to notice it, based on physical signs that build up gradually and silently. A well-fitted night guard protects against that ongoing damage, covering both your teeth and your jaw.
At Clove Dental, we check for signs of grinding at every routine exam. Book your appointment at clovedds.com and find out if a night guard could be protecting more than you realize.
How do I know if I actually need a night guard?
A dental exam can identify physical signs of grinding, such as worn enamel or small fractures, even if you've never noticed symptoms yourself. That evaluation is the most reliable way to know.
Are custom night guards worth the extra cost compared to store-bought ones?
For most patients, yes. A custom fit provides more consistent protection, better comfort and is less likely to shift out of place during sleep compared to generic options.
Can children need night guards too?
Yes, grinding can occur in children as well, though it's often monitored differently since some childhood grinding resolves on its own as adult teeth come in.
Will my dentist in Camarillo check for grinding at a regular cleaning?
Yes, signs of grinding are typically part of a routine exam, since dentists look at enamel wear patterns and bite function as standard practice during checkups.
