Key Takeaways:
Protection:
Night guards, whether custom-fitted by a dentist or store-bought, create a cushion between the teeth, preventing them from grinding directly against each other.
Reduced damage:
By preventing this contact, night guards help to avoid tooth wear, chipping, cracking, and other damage associated with bruxism.
Jaw pain relief:
Night guards can also alleviate jaw pain and muscle soreness by encouraging the jaw muscles to relax.
Sleep improvement:
By minimizing the disruptive effects of grinding, night guards can contribute to better sleep quality.
Beyond bruxism:
Night guards can also be used to treat TMJ disorders and even help with sleep apnea.
Addressing the root cause:
While night guards are effective in preventing damage, it's also important to address the underlying causes of bruxism, such as stress or certain medications.
Custom vs. Store-bought:
Custom-fitted night guards, made by a dentist, are often preferred for a more comfortable and effective fit.

Understanding night guard effectiveness: What they do
Night guards don't stop you from grinding. They prevent teeth damage from grinding.
It kind of works like a helmet. But, for the teeth. A helmet absorbs shock to protect your skull. Similarly, a night guard absorbs the pressure between your upper and lower teeth when grinding occurs.
So while the grinding motion might still occur, the teeth damage from grinding is significantly reduced. Or, in most cases, completely avoided. They also help with teeth sensitivity.
The dental guard benefits that matter
So, what are the benefits of wearing a night guard? You might have thought of this question. To answer it, here's a breakdown of the benefits of using a night guard:
-
Protection from teeth grinding: Prevents enamel wear, micro-cracks, and chipping caused by constant clenching.
-
Bruxism prevention aid: While night guards don't stop grinding entirely, they reduce its frequency by positioning the jaw in a more relaxed alignment. Especially helpful for stress-induced bruxism.
-
Oral health protection: Guards against long-term complications like jaw misalignment, TMJ disorders, and receding gums.
-
Better sleep: By relieving pressure in your jaw, night guards can reduce tension headaches and improve your sleep quality.
Since these dental guard benefits are hard to ignore…

Why do some people still experience tooth damage?
Teeth damage from grinding, even after wearing a night guard, can happen. The causes often are:
-
Improper fit: Store-bought or “boil-and-bite” guards can feel bulky, slip during sleep, or not cover all teeth.
-
Worn-out materials: Older guards lose their effectiveness if not replaced when they degrade.
-
Skipping usage: Sporadic use fails to prevent cumulative damage.
Just like wearing protective equipment improperly for any other part of the body can cause injury, the same goes for wearing improper night guards.
Pro Tip:
A professionally fitted night guard offers the best long-term night guard results, ensuring comfort, protection, and durability.
Adjusting to a night guard
Just like adjusting to contact lenses or orthodontic aligners, the first few nights may feel awkward. You might experience:
-
Extra saliva production (your mouth thinks it's chewing something)
-
Slight discomfort or pressure
-
A temporary lisp when speaking
But here's the upside: Night guard results show up quickly. For many, the relief from morning jaw pain or headaches kicks in a few days. And so, most users adapt within a week.
What type of night guard should you wear?
Night guard effectiveness changes with the material and the grinding intensity for which they are made. So, the best is to wear a custom night guard, made by dental professionals, aligning with your unique requirements.

How do I stop bruxism permanently?
Night guards are a powerful line of defense against the impact of bruxism. But if you're seeking a permanent solution for bruxism itself, it starts with understanding why you grind. Root causes of bruxism include:
-
Stress and anxiety
-
Sleep disorders (like apnea)
-
Misaligned bite or missing teeth
-
Lifestyle habits (alcohol, caffeine, smoking)
Long-term fixes might include:
-
Stress reduction techniques (meditation, therapy)
-
Physical therapy for jaw tension
-
Dental correction (aligners, crowns)
-
Medication (in severe neurologic cases)
Night guards work best when combined with efforts to address the root cause of grinding.
So… Do night guards actually work?
Yes. Night guard effectiveness is backed by both anecdotal success and clinical evidence. They may not stop the habit altogether, but they do what matters most: prevent irreversible damage to your teeth and jaw.
In fact, patients who consistently wear night guards report:
-
Fewer headaches and facial tension
-
No new chipping or enamel wear
-
Improved sleep
-
Greater peace of mind
And with innovations in fit, comfort, and materials, modern night guards are more wearable than ever.
