Mouth Guards in Brisbane: When do you need one.

A mouthguard is one of the simplest ways to protect your teeth - whether you're playing contact sport or grinding your teeth at night. At Aminya St Dental, we make custom mouthguards for adults and children in Mansfield, Brisbane.

There are two main types: sports mouthguards and night guards for teeth grinding. This guide explains both, and helps you work out which one you need.

Sports mouthguards 

The Australian Dental Association recommends mouthguards for any sport involving physical contact, collision, or the risk of impact to the face. This is not limited to obviously contact-heavy sports. The risk is present in a broader range of activities than most parents and players realise.

Sports where mouthguards are strongly recommended

• Full-contact sports: rugby union, rugby league, AFL, boxing, martial arts, wrestling

• Collision sports: hockey, soccer, basketball, netball, water polo

• Individual activities with fall risk: cycling, skateboarding, BMX, horse riding, gymnastics

• Racquet sports: squash and basketball involve fast-moving objects and other players in close proximity

  
  

A well-fitted guard absorbs and distributes the force of an impact across the jaw, significantly reducing the risk of jaw fractures, lacerations to the lips and cheeks, and concussion because the guard prevents the lower jaw from snapping upward into the upper jaw and skull on impact. That force transmission is the mechanism behind sports-related concussions that a guard can partially mitigate. At Aminya St Dental, we can also customize the mouthguard to any team color.

Night guards and bruxism - what is happening when you grind your teeth?

Bruxism is the clinical term for grinding or clenching teeth. It most commonly occurs during sleep, which is why many people are unaware they do it until a partner notices the sound, or a dentist identifies the wear pattern during a routine check-up.

What bruxism does to your teeth over time

This is the section competitors omit entirely, and it matters because many bruxism patients don't feel symptoms immediately. The damage accumulates over years.

• Enamel wear: the grinding gradually removes the hardest layer of the tooth. Once enamel is gone, it does not regenerate. The underlying dentine — which is softer and yellower — becomes exposed, leading to sensitivity, discolouration, and accelerated decay risk.

• Tooth fractures: the repeated stress causes micro-fractures in the enamel that eventually propagate into the tooth structure. Cusps chip. Fillings fracture. Existing crowns can crack.

• Gum recession: the clenching force transmits down the root, causing the bone and gum around the tooth to recede gradually.

• Jaw joint damage: prolonged bruxism can cause or worsen temporomandibular joint (TMJ) dysfunction — clicking, locking, and pain in the joint in front of the ear.

• Headaches and facial pain: the masseter and temporalis muscles — the jaw-closing muscles — are under sustained contraction during bruxism. Chronic tension in these muscles causes morning headaches, temple pain, and facial soreness that patients often attribute to other causes.

The reason a night guard is recommended early, even before significant symptoms appear is that the damage is largely irreversible. Worn enamel and fractured teeth require restorative treatment. Catching bruxism before that stage means a guard can protect the existing teeth indefinitely.

When should a child start wearing a mouthguard?

As soon as they are participating in a sport that carries impact risk. This includes primary school sport, not just secondary school or club-level competition. A child playing soccer at eight years old is at the same risk of a dental impact as a teenager playing the same sport.

How often does a child's guard need replacing?

Because a child's jaw and teeth are actively growing and changing, a custom mouthguard will not fit correctly indefinitely. As a general guide, children should have their guard checked at every dental visit, typically every six months and replaced when the fit is no longer precise. During periods of active dental development (typically ages 6 to 12 when the permanent teeth are erupting), replacement may be needed annually. A guard that no longer fits is not providing the protection the child thinks it is.

Does the CDBS cover children's mouthguards?

Yes. Mouthguards for children are an eligible service under the Child Dental Benefits Schedule, subject to the available benefit cap and the frequency restrictions on CDBS item numbers. If your child is CDBS eligible, the cost of a custom guard may be partially or fully covered. Confirm with the practice when booking. Read more about Child Dental Benefits Schedule here.

What if you already have crowns, veneers, or implants?

Custom guards can be fabricated over existing dental restorations, but the guard design and material need to account for them. A crown or veneer surface requires even force distribution, a poorly fitting guard that creates a pressure point on a crown can fracture the restoration. An implant-supported tooth has different loading characteristics to a natural tooth, and the guard should account for that.

The practical implication: tell the dentist about any crowns, veneers, bridges, or implants when being fitted for a guard. This is not a barrier to having a guard made, it is simply information the lab needs to fabricate it correctly.

How a custom mouthguard is made at Aminya St Dental

If you’re interested in mouthguards in Brisbane CBD, start by arranging an appointment for an evaluation. We can provide estimates of cost and walk you through exactly what’s involved. When you have your visit, we’ll take impressions of your teeth and use this information to make a mouthguard that’s a perfect fit for you.

Signs you may need a night guard:

• You wake up with a sore or stiff jaw

• You have regular morning headaches, particularly at the temples

• Your teeth feel sensitive, especially to cold, without obvious decay

• A partner has told you that you grind or clench your teeth during sleep

• Your dentist has mentioned flattened or worn tooth surfaces at a check-up

• You have unexplained chipped or cracked teeth, or fillings that fracture repeatedly

• You have clicking, popping, or pain in the jaw joint

If you are not sure whether you need a guard, or which type is right for your situation, the dentist can assess this at a standard appointment. For children's sports guards, let the practice know if your child is CDBS eligible when you book.

To book an appointment, call (07) 3349 7749 or book online. We are open Monday to Saturday at 2/14 Aminya St, Mansfield QLD 4122.

Frequently asked questions about mouthguards in Brisbane

Do I need a mouthguard for sport?

If your sport involves physical contact, collision, fast-moving objects, or a significant fall risk, yes. The Australian Dental Association recommends mouthguards for a wide range of sports including rugby, AFL, soccer, hockey, basketball, netball, cycling, and martial arts. A custom mouthguard fitted by a dentist provides significantly better protection than a chemist boil-and-bite option.

How do I know if I grind my teeth at night?

Common signs include waking with a sore or stiff jaw, morning headaches, tooth sensitivity, and a partner reporting grinding sounds during sleep. A dentist can also identify wear patterns and micro-fractures during a routine examination that indicate bruxism even when symptoms are absent.

Why is a custom mouthguard better than a boil-and-bite?

A custom guard fits precisely against every tooth surface, distributing impact force evenly. A boil-and-bite guard fits approximately, which can create pressure points and requires clenching to stay in place, increasing jaw muscle tension rather than reducing it. Custom guards are also made from materials appropriate to the specific use.

How often do children's mouthguards need replacing?

At every dental visit, typically every six months, the fit should be checked. During active growth phases, a child may need a new guard annually. A guard that no longer fits correctly is not providing meaningful protection.

Does the Child Dental Benefits Schedule cover mouthguards for children?

Yes, mouthguards are a CDBS-eligible service. Subject to your child's available benefit cap and applicable item number restrictions, the cost may be partially or fully covered. Confirm with the practice when booking.

What if I have crowns or veneers, can I still get a mouthguard?

Yes. The guard is fabricated over your existing restorations. Inform the dentist of any crowns, veneers, bridges, or implants at the impression appointment so the laboratory can account for them in the design.
