Birmingham’s Leading Bruxism Specialists
Mouth Guards And Bruxism.
If you have been told you grind your teeth, a mouth guard is probably the first thing your dentist has mentioned. And for good reason. The NHS recommends mouth guards and splints as the primary dental treatment for bruxism, worn at night to protect teeth from damage.
They are a sensible starting point, and for many people with mild bruxism they provide meaningful protection.
But mouth guards have real limitations that are worth understanding before you commit to one. This page explains honestly what they do, what the different types cost, where to get one, and why some patients find they need something more.

What Do Mouth Guards Actually Do?
A mouth guard, also called a splint or occlusal appliance, fits over your upper or lower teeth and creates a barrier between the two sets of teeth during sleep. When you grind, the guard absorbs the friction rather than your enamel. This protects against tooth wear, reduces the risk of chipping and fracturing, and can help with jaw pain in some patients.
What it does not do is stop the grinding itself. The masseter muscle continues to contract with the same force as before. The underlying brain activity driving sleep bruxism is unchanged. Sleep bruxism happens due to brain activity while you are asleep. There is no way of stopping the brain signals that trigger the bruxism activity.
A mouth guard manages the consequences of that activity. It does not address the cause.
This distinction matters because many patients wear a guard consistently and still wake with jaw pain, headaches and facial tension. The teeth may be protected, but the muscle overactivity continues unimpeded.
What Are The Different Types of Mouthguards?
Not all mouth guards are the same, and the differences matter more than most people realise.
Custom Fitted Mouth Guards
These are made from impressions of your teeth by a dental laboratory and fit precisely over your upper or lower teeth. They can be made by a dentist to fit precisely over your upper or lower teeth.
A well-fitted custom guard is the most effective option for protecting teeth, the most comfortable to wear consistently and the most durable. Custom guards come in two main types:
Soft Splints
Soft splints are made from a flexible material similar to a sports gumshield. They are often more comfortable initially but have a significant drawback. Some people find that soft splints make them clench or grind more, which can make jaw pain worse. Some people find that they wear through their soft splint very quickly.
Over-the-counter guards
Pharmacies sell boil-and-bite guards that mould to your teeth when heated. These are significantly cheaper than custom-fitted options but rarely fit well.
An ill-fitting guard can cause bite problems, gum irritation and, as with soft custom guards, can worsen clenching in some patients. They are an option for very mild cases but are not recommended for moderate to severe bruxism.
How to Get a Mouth Guard Through the NHS.
A dentist may recommend a mouth guard or mouth splint for bruxism, worn at night to protect teeth from damage.
If your NHS dentist determines that a guard is clinically appropriate, it can be provided as part of your NHS treatment.
A laboratory-made custom guard falls under Band 3 NHS dental treatment, which covers complex treatments requiring dental laboratory work. From April 2026, the Band 3 charge in England is £332.10. This is a single charge covering the entire course of treatment, including the fitting appointment and any adjustments.
Some patients are exempt from NHS dental charges entirely, including children under 18, pregnant women, and those receiving certain means-tested benefits. If you are unsure whether you qualify for free or reduced-cost treatment, your dentist can advise, or you can check via the NHS Low Income Scheme.
If you do not currently have an NHS dentist, you can find one using the NHS dentist finder.
What About Mouthguards Through Private Practices?
Private custom-fitted mouth guards typically cost between £150 and £600 depending on the type, material and dental practice.
The advantage of going private is often faster access, more appointment flexibility and a wider range of materials.
The guard itself is not necessarily superior to an NHS one, but the service and turnaround may be.
If you are already a private dental patient, speak to your dentist directly about having a guard made.
When is a Mouth Guard Not Enough?
For many patients, a mouth guard is a useful tool but an incomplete solution.
The most common scenario is this: the guard protects the teeth, but the jaw pain, morning headaches, facial tension and disrupted sleep continue. The grinding has not stopped. The muscle is still overactive every night. The damage is just happening to the guard rather than the teeth.
This is the point at which patients typically begin looking for something that addresses the muscle activity itself rather than its consequences.
Botox injected into the masseter muscle reduces the force of jaw contractions during both sleep and waking hours. Botulinum toxin (Botox) injection into the jaw muscles can be used to relax the muscles.
Unlike a mouth guard, it works on the source of the problem. Most patients notice a meaningful reduction in jaw tension, headaches and pain within two weeks of treatment, with results lasting five months or more.
A mouth guard and Botox treatment can also be used alongside each other. The guard continues to protect the teeth while the Botox reduces the muscle activity driving the grinding.
For patients with significant tooth wear, this combined approach is often the most sensible option.

For mild bruxism where the main concern is protecting teeth, a mouth guard from your dentist is a sensible first step and is available on the NHS. For patients with significant jaw pain, persistent headaches, disrupted sleep or symptoms that continue despite wearing a guard, Botox treatment addresses the underlying muscle activity in a way a guard cannot. Many patients benefit from using both together. Dr. Farmah will give you an honest recommendation based on your specific situation at your consultation.
es. A custom-fitted guard is available through your NHS dentist as a Band 3 treatment, which costs £332.10 in England from April 2026. Some patients qualify for free treatment depending on their circumstances. Use the NHS dentist finder to locate a practice near you.
This is a recognised issue, particularly with soft guards. Some people find that soft splints make them clench or grind more, which can make jaw pain worse.
If this has happened to you, speak to your dentist about switching to a hard stabilisation splint, or consider whether Botox treatment to reduce the muscle activity might be more appropriate.
They offer some protection against tooth wear but rarely fit well enough to be fully effective, and an ill-fitting guard can cause bite problems or worsen clenching. They are only suitable for very mild cases. For anything beyond occasional mild grinding, a custom-fitted guard made by a dentist is worth the investment.
Yes, and for many patients this is the most effective approach. The guard protects the teeth from ongoing damage while Botox reduces the force of the grinding itself. Dr. Farmah can advise on the best combined approach at your consultation.
No. Botox for bruxism is a private treatment. The NHS does not currently offer it. No GP referral is needed to book at The Bruxism Clinic.
