Waking up with jaw soreness, tooth sensitivity, or unexplained headaches can be frustrating, especially when the cause isn’t obvious. For many people, the issue lies in what happens during sleep. Teeth grinding and jaw clenching often occur without awareness, slowly causing damage over time. This is where a night guard for teeth becomes an essential part of protecting long-term oral health. Designed to act as a protective barrier, it helps minimise wear and reduces strain on the jaw while you rest.
Teeth grinding at night, also known as bruxism, is more common than many realise. Ongoing pressure from clenching can wear down enamel, weaken restorations, and lead to ongoing discomfort. Left untreated, it may result in cracked teeth, jaw joint problems, and increased dental treatment needs. Early awareness and appropriate intervention can make a meaningful difference.
For Ipswich residents seeking effective protection, understanding how a night guard for teeth works is the first step toward lasting relief. This guide explains your options, benefits, and when a professional assessment is recommended.
Understanding Teeth Grinding (Bruxism)
Bruxism is the medical term for clenching or grinding your teeth outside of normal chewing. It is involuntary; you may not even be aware that you do it until symptoms appear. In Australia, approximately half of the population grinds occasionally, and roughly 5% do so regularly. It affects adults and children alike. Often, stress and anxiety trigger grinding, but it can also be linked to intense concentration, certain medications, or even sleep apnoea.
When bruxism strikes, your teeth and jaw take the brunt. Common signs include jaw muscle pain, headaches, earaches and chipped or sensitive teeth. In fact, daily wear-and-tear from grinding can wear away the hard enamel surface. Over time, a tooth’s enamel is ground down until the softer dentine shows, leading to sensitivity and damage. Worse still, severe grinding can crack or even break teeth.
Your teeth have a hard enamel “crown” that protects the inner layers. Grinding wears down this enamel over time. An occlusal night guard acts like a durable shield over the enamel, absorbing the grinding forces so the teeth themselves stay intact.
It’s common not to notice your own grinding; often, a partner hears it. Many people only discover the problem after a dentist points out unusual wear patterns. Regardless of how subtle it is, untreated bruxism can lead to serious oral damage. That’s why using a night guard is considered one of the best teeth grinding solutions: it prevents tooth damage from grinding and relieves painful jaw strain.
How Night Guards Protect Your Teeth
A night guard (also called a bite splint or occlusal splint) is a dental device you wear over your upper or lower teeth at night. It creates a cushioning barrier between opposing teeth, absorbing the stress of clenching and grinding. As the Victorian Department of Health explains, a special mouthguard (‘bite splint’) to wear at night can protect your teeth, even though it won’t completely stop the grinding habit.
In practice, a night guard fits snugly onto your teeth. When you grind, the plastic splint takes the impact instead of your enamel. This not only prevents chips and cracks, but it can also ease muscle tension. By covering the biting surfaces, the guard distributes forces evenly and stops sharp enamel edges from engaging.
In short, a night guard does not magically cure stress or anxiety, but it effectively prevents damage. In other words, the guard takes the wear and tear, preserving your smile. This means fewer chips, less jaw ache and a reduced risk of needing fillings or crowns later on.
Dentists often describe a night guard as a “cushion” or “shock absorber” for your teeth at night. It’s like putting rubber soles on each tooth: the constant gnashing forces get soaked up by the splint’s material. Over the long term, that can prevent serious problems such as fractured teeth, fillings wearing out, or temporomandibular joint (TMJ) disorders. In fact, if left unchecked, bruxism can cause teeth to wear and may damage the teeth and the jaw joint. Using a night guard breaks that cycle by giving your teeth a safe stopping point.
Custom vs Off-the-Shelf Night Guards
When it comes to choosing a night guard, you have a few options. Broadly speaking, there are custom-made guards (crafted by a dentist) and over-the-counter guards (stock or boil-and-bite types). Here’s a quick comparison of the main differences:
Custom Night Guard (Dentist-Made): These are moulded to fit your teeth exactly. Your dentist takes an impression and sends it to a lab, which fabricates a hard acrylic guard tailored to your bite. The fit is precise, making it very comfortable to wear. Custom guards tend to be more durable and are often made of higher-quality materials. They usually cost more but provide the best protection and comfort for regular grinders.
Boil-and-Bite Night Guard (Store-Bought): These come as a thermoplastic mouthpiece that you soften in hot water and then bite into to shape. They fit somewhat better than generic stock guards, but not as perfectly as custom ones. Boil-and-bite guards are cheaper (typically under $50) and can offer reasonable protection for mild grinding. However, the fit may feel bulky, and they can wear out faster.
Stock Night Guard (Pre-Formed): These are ready-made mouthpieces (hard or soft plastic) that you simply slip on. They are the least expensive option. The fit is generic and often uncomfortable; a loose or poorly fitting guard might actually encourage more jaw tension. Stock guards wear down quickly and can shift in the mouth, so dentists generally do not recommend them for severe grinding.
Other Bruxism Solutions
While night guards are the primary shield against damage, managing bruxism often involves treating underlying causes. Because stress and anxiety are common triggers, relaxation techniques can complement your guard. In practice, many people use a combination: they wear a night guard and also work on stress relief during the day.
Additionally, if jaw clenching is linked to TMJ (jaw joint) issues, a doctor might explore treatments like physiotherapy or bite adjustments. In other words, the night guard becomes part of an overall strategy to ease jaw strain.
A useful step is to have your dentist check for factors like an uneven bite or sleep apnoea. Sometimes, a small bite adjustment or treating sleep apnoea can significantly reduce bruxism. But regardless of the cause, the immediate teeth-saving solution is the guard. It’s like putting a line of defence between you and your own teeth.
Choosing and Using a Night Guard
If you suspect grinding, the first step is to talk to your dentist. They can confirm bruxism by examining wear patterns on your teeth. Most dentists can then custom-fit a night guard for you. This usually involves one or two appointments: an impression of your teeth is taken (often a simple putty mould), then sent to a dental lab. In a week or two, you return to collect the guard and have any final adjustments made. Because it’s moulded to your bite, a custom night guard should feel secure and allow normal jaw movement.
For those on a budget, over-the-counter guards are widely available in pharmacies. As mentioned, boil-and-bite guards can be shaped at home. The process: submerge the guard in hot water for a moment, let it cool slightly, then clamp down with your teeth and hold to form an impression. It’s less precise than a dentist’s mould, but it still works fairly well. Just follow the instructions carefully to avoid burns and to get the best fit.
Regardless of type, wear your guard every night. Even missing a few nights means renewed enamel contact and possible micro-damage. Eventually, your teeth will get used to the guard; many patients wake up surprised at how normal it feels, or how much relief they have. Be sure to clean it daily: brush it with a separate toothbrush and gentle soap. Store it dry in its case away from pets. Over time, the guard itself will show wear; a general rule is to replace it if it becomes cracked or no longer fits well. Your dentist can advise on the right schedule.
Conclusion
Teeth grinding and jaw clenching during sleep can quietly cause long-term damage if left unaddressed. Throughout this guide, we’ve explored how nighttime grinding affects your teeth, jaw, and overall comfort, as well as the role a properly fitted night guard plays in reducing wear and strain. By acting as a protective barrier, a night guard helps preserve enamel, protect dental work, and ease pressure on the jaw, making it a practical and preventative solution.
We’ve also highlighted why professional assessment matters. Not all night guards are the same, and a personalised approach ensures better comfort, fit, and long-term protection. Addressing grinding early can help avoid more complex dental concerns and support better oral health outcomes over time.

FAQs:
Does wearing a night guard stop teeth grinding?
A night guard does not cure bruxism itself, but it prevents damage. It acts like a hard plastic shield covering your teeth while you sleep. This means even if you continue to grind or clench, the force is taken by the guard rather than your enamel. In other words, the guard protects your teeth from wear and fractures, though you may still grind on the splint. Over time, addressing stress or other causes can reduce the grinding habit, but the guard’s main job is tooth protection.
Are custom night guards better than store-bought ones?
Custom guards (made by a dentist) fit exactly to your bite, offering the most comfort and durability. Store-bought boil-and-bite guards can be a good start for mild grinding, but they often feel bulkier and wear out sooner. If you grind heavily or have sensitive teeth, a custom night guard is usually worth the extra cost. Your dentist can design one that fits perfectly and gives stronger protection.
How else can I reduce teeth grinding at night?
In addition to using a night guard, try stress-reduction techniques: practice relaxation exercises, ensure a calming bedtime routine, and limit caffeine or alcohol in the evening. Staying hydrated and stretching your jaw muscles with a gentle massage before bed can help too. Sometimes counselling or breathing exercises make a big difference. And of course, maintain regular dental check-ups so your dentist can monitor any grinding and recommend changes if needed.
