A night guard protects your teeth from grinding. It does not stop you grinding, and it does not treat whatever is causing it. That distinction is worth understanding before you buy one, because the searches for night guards in Australia return mostly products, and a product cannot tell you why your jaw is working overtime at 3am.<\/p>\n\n\n\n

\"A<\/figure>\n\n\n\n

What a night guard actually does<\/h2>\n\n\n\n

Orthodontics Australia describes the job plainly: “the purpose of a night guard is to create a barrier between your teeth, so they don’t grind together”<\/a>.<\/p>\n\n\n\n

That barrier is genuinely valuable. Grinding wears enamel, cracks teeth and destroys fillings, and once enamel is gone it does not grow back. A splint takes that damage instead of your teeth.<\/p>\n\n\n\n

What it does not do is stop the grinding itself. The muscles still clench. If you wake with a sore jaw, you may still wake with a sore jaw, just with intact teeth.<\/p>\n\n\n\n

Why grinding happens, which is the part that matters<\/h2>\n\n\n\n

According to healthdirect, bruxism is grinding or clenching “that is not part of normal chewing”<\/a>, and the possible triggers include emotional stress and anxiety, smoking, alcohol or caffeine, snoring, some antidepressants and stimulant drugs.<\/p>\n\n\n\n

Some of those you can act on yourself. Others need a conversation with a doctor rather than a dentist, particularly if a medication is involved. What none of them respond to is a plastic guard alone.<\/p>\n\n\n\n

healthdirect lists the treatments accordingly: stress reduction, counselling including cognitive behaviour therapy, relaxation techniques, dental repairs where damage has already happened, physiotherapy, treating any linked condition, and a custom-made mouthguard, known as an occlusal splint, to protect the teeth. The splint is one item on that list, not the list.<\/p>\n\n\n\n

The connection most product pages will not mention<\/h2>\n\n\n\n

There is one trigger on that list worth separating out. healthdirect notes that “people who grind their teeth while asleep may be more likely to have other sleep disorders, such as sleep apnoea”<\/a>, and that dentists may refer patients to a doctor for sleep apnoea screening where sleep bruxism is suspected.<\/p>\n\n\n\n

That matters because sleep apnoea is a medical condition with consequences well beyond your teeth. If you grind, snore, and wake unrefreshed, the grinding may be the most visible symptom of something else entirely. Buying a guard online and moving on would leave the actual problem untouched.<\/p>\n\n\n\n

This is one of the few situations where having a dentist and a GP in the same building is practically useful rather than just convenient. King Street Medical<\/a> sits alongside the dental practice, so a referral for screening does not mean starting again somewhere new.<\/p>\n\n\n\n

\"King<\/figure>\n\n\n\n

Custom-made versus off-the-shelf<\/h2>\n\n\n\n

Orthodontics Australia notes that guards “can be bought off-the-shelf or made to order”, and that a custom guard is made by “taking moulds of your teeth to make an exact replica that sits over the top, decreasing any chance of discomfort or ill-fitting”<\/a>.<\/p>\n\n\n\n

The fit is not a comfort question alone. The same source cautions that an ill-fitting, non-custom guard may allow teeth to move, which is the opposite of what you are paying for. It also sets a clear standard that is easy to apply at home: you should not feel any pain or serious discomfort with a night guard.<\/strong> If yours hurts, it is not right, whatever it cost.<\/p>\n\n\n\n

If you are having orthodontic treatment, raise the guard with whoever is managing it before wearing one, because a splint can interfere with tooth movement that is deliberately in progress.<\/p>\n\n\n\n

Signs worth getting looked at<\/h2>\n\n\n\n

healthdirect lists the signs of grinding as cracked, chipped or loose teeth, damaged fillings, painful jaw muscles, headaches, sensitive teeth and disturbed sleep. Some people have no symptoms at all.<\/p>\n\n\n\n

That last point is why grinding is so often found by someone else. A dentist sees the flattened wear pattern at a routine check-up<\/a> long before most people notice anything, which is the cheapest possible moment to deal with it.<\/p>\n\n\n\n

Frequently asked questions<\/h2>\n\n\n\n

Will a night guard stop me grinding my teeth?<\/h3>\n\n\n\n

No. A night guard creates a barrier so the teeth do not grind against each other, which protects them from wear and cracking. The grinding itself continues. Stopping it means addressing the cause, which healthdirect lists as potentially stress and anxiety, smoking, alcohol or caffeine, snoring, or certain medications, and sometimes an underlying sleep disorder.<\/p>\n\n\n\n

Are chemist night guards as good as a dentist-made one?<\/h3>\n\n\n\n

They are not equivalent. Orthodontics Australia notes a custom guard is made from moulds of your teeth so it fits exactly, and warns that ill-fitting non-custom guards may allow teeth to move. A useful test either way: a night guard should not cause pain or serious discomfort. If it does, stop wearing it and have it checked.<\/p>\n\n\n\n

Can teeth grinding be a sign of sleep apnoea?<\/h3>\n\n\n\n

It can be associated with it. healthdirect states that people who grind their teeth while asleep may be more likely to have other sleep disorders, including sleep apnoea, and that dentists may refer patients for sleep apnoea screening where sleep bruxism is suspected. If you also snore or wake unrefreshed, mention it, because that changes what should be investigated.<\/p>\n\n\n\n

How would I know if I grind my teeth in my sleep?<\/h3>\n\n\n\n

Often you would not. Common signs are jaw muscle pain, headaches, sensitive teeth, chipped or cracked teeth and damaged fillings, but healthdirect notes some people have no symptoms at all. A partner may hear it, or a dentist may spot the wear pattern at a routine examination before you notice anything.<\/p>\n\n\n\n

\"The<\/figure>\n\n\n\n

If you suspect you grind, the useful first step is an examination rather than a purchase. King Street Dental provides nightguards and splints<\/a> at its Warrawong practice<\/a>, and can tell you whether the wear on your teeth needs protecting now and whether anything else should be looked into.<\/p>\n\n\n\n
