Standard boil-and-bite guards are not suitable for brace wearers — they cannot be formed around brackets. This guide explains which types are safe, how night guards for bruxism fit alongside orthodontic treatment, and what to expect in terms of cost and care.

A mouthguard absorbs and spreads the force of a blow, protecting the teeth, the appliance and the lips and cheeks, which can be cut against brackets. A bracket knocked off or a wire bent in a sports injury needs an extra repair visit, and while it is detached that tooth stops moving as planned, which can add weeks to treatment. For patients who grind at night, the question is different: the aim is to protect enamel and retainers without holding teeth still while they are being moved, which is covered below. ## Why standard mouthguards do not work with fixed braces Standard boil-and-bite mouthguards are formed by softening the guard in hot water and biting into it to create an impression. When brackets are present on the teeth, this process traps the softened material around the metal, which then locks onto the brackets when it cools. Removing the guard risks pulling brackets off the teeth. Standard boil-and-bite guards also fail to accommodate the ongoing tooth movement during orthodontic treatment — as teeth move, the guard becomes progressively less well-fitting over the following weeks. For any patient with fixed braces playing contact sport, a standard boil-and-bite guard is not an acceptable solution. ## Custom orthodontic sports mouthguards — what they are and how they work A custom orthodontic mouthguard is fabricated by a dentist or orthodontist from a dental impression or digital scan taken over your current brace configuration. The guard is made from laminated thermoplastic sheeting and built with extra bulk on the bracket-side surface to cushion the soft tissues — lips and inner cheeks — against impact without pressing directly onto the brackets. This protects both the soft tissues and the brackets in the event of a collision. Custom guards must be updated periodically during orthodontic treatment — typically every six to twelve months — as tooth positions change and the original fit becomes less accurate. The updated guard ensures continued protection as treatment progresses. ## Sports governing body rules in the UK Several UK sports governing bodies mandate mouthguard use, and these rules apply regardless of whether a player wears braces. The Rugby Football Union (RFU) Laws of the Game recommend mouthguards for all players, and many clubs and schools make them mandatory. England Hockey recommends mouthguard use and many leagues require them. Boxing and martial arts organisations mandate custom mouthguards in competitive contexts. Lacrosse and American football players are also expected to wear appropriate protection. Players with fixed braces must meet the same regulations as those without braces — a custom orthodontic guard is the appropriate way to satisfy both the rules and protect the appliance. Check your specific sport's governing body regulations before your first session. ## Custom vs boil-and-bite for brace wearers — what to choose Custom guards are the recommended standard for fixed brace wearers. Some manufacturers produce purpose-designed orthodontic boil-and-bite mouthguards with pre-formed channels to accommodate brackets without locking onto them. These are significantly better than standard boil-and-bite guards and represent a practical lower-cost option for patients who cannot access a custom guard promptly. However, their fit is less precise than a custom-fabricated guard and their protective properties are correspondingly inferior. If you play contact sport and cannot immediately access a custom guard, an orthodontic boil-and-bite guard provides short-term protection while a custom guard is made. Do not use a standard guard. ## Night guards for bruxism during orthodontic treatment Bruxism — night-time tooth grinding or clenching — is a separate concern from sports protection. Many patients who grind their teeth sleep in a night guard (also called an occlusal splint). Wearing a standard night guard during orthodontic treatment creates a significant problem: the guard holds teeth in a fixed position while orthodontic forces are trying to move them. A rigidly fitting hard acrylic night guard can resist tooth movement and significantly slow or even prevent progress. If you grind your teeth and are about to start orthodontic treatment, discuss this with your orthodontist before continuing to wear your existing night guard. A modified, passive soft guard may be appropriate in some cases; in others, the orthodontist may advise pausing night guard wear and monitoring the teeth directly. ## Mouthguards with clear aligners Clear aligner wearers have more flexibility than fixed brace patients. Aligners can be removed before contact sport, and a standard mouthguard (or custom guard) can be worn over bare teeth during the session. Aligners should be stored safely in a protective case while sport is played and reinserted immediately after. For non-contact sport, aligners can be worn without any additional protection. For patients who grind their teeth during aligner treatment, the aligner itself provides some passive protection against tooth-to-tooth contact — though it is not designed as a bruxism splint. Discuss any concerns about grinding with your orthodontist, who may be able to adapt the aligner material or treatment plan accordingly. ## How to clean a mouthguard alongside braces treatment Mouthguards used with fixed braces collect plaque and debris around the bracket-contact areas and must be cleaned after every use. Rinse the guard under cold water immediately after removal — never use hot water, which can warp the material. Brush the guard gently with a soft toothbrush and mild soap or a non-abrasive toothpaste, paying attention to the inside surfaces that contact the brackets and gum tissue. Allow the guard to air-dry in its case before storing. Do not soak orthodontic guards in mouthwash for extended periods — the alcohol content in many mouthwashes degrades thermoplastic materials. Replace the guard when it shows visible wear, becomes discoloured, or no longer fits accurately due to tooth movement. ## Cost and NHS availability Custom orthodontic mouthguards are not routinely available on the NHS. They are typically provided privately by dentists or orthodontic practices. Costs in the UK in 2026 range from approximately £50 to £150 per guard, depending on the practice and the complexity of the design. Replacement guards during treatment are charged at a similar rate. Some orthodontic practices include a custom guard in the overall treatment fee for patients who are known sports players — ask about this at the start of treatment. Purpose-designed orthodontic boil-and-bite guards are available from dental suppliers and some pharmacies for approximately £15 to £30 and represent a more accessible interim option. ## Useful related pages [Braces and Sports UK](https://virtualconsultant.online/guides/sports-with-braces-uk) [Braces and Swimming UK](https://virtualconsultant.online/guides/braces-and-swimming-uk) [Bruxism and Braces UK](https://virtualconsultant.online/guides/bruxism-and-braces-uk) [Bruxism After Braces UK](https://virtualconsultant.online/guides/bruxism-after-braces) [Broken Braces](https://virtualconsultant.online/guides/broken-braces) [Orthodontic Emergency Kit UK](https://virtualconsultant.online/guides/orthodontic-emergency-kit-uk) [Retainers After Braces](https://virtualconsultant.online/treatments/retainers) [Life With Braces](https://virtualconsultant.online/guides/life-with-braces) This guide is for general information only.

Standard boil-and-bite mouthguards are not suitable for use with fixed braces — the softened material molds around the brackets and locks onto them, risking pulling brackets off when the guard is removed. Purpose-made orthodontic boil-and-bite guards with pre-formed bracket channels exist and are a better temporary option, but a custom-made orthodontic mouthguard fabricated by your dentist provides the best protection and fit for brace wearers in contact sport. How often do I need to replace my orthodontic mouthguard? Custom orthodontic mouthguards should be updated every six to twelve months during active treatment as your teeth move and the fit becomes less accurate. A poorly fitting guard does not provide reliable protection. If the guard feels loose, uncomfortable, or is visibly distorted, have it assessed by your dentist or orthodontist who can arrange a new one from a fresh impression of your current tooth positions. Can I wear my night guard during orthodontic treatment? This depends on the type of night guard and your specific orthodontic situation. A rigid hard acrylic night guard can resist tooth movement and slow orthodontic progress significantly, so most orthodontists advise pausing or modifying night guard wear during active treatment. Discuss this with your orthodontist before continuing to use an existing guard — they will advise on the safest approach for your case. Do clear aligner patients need a mouthguard for sport? Clear aligner patients can remove their trays before contact sport and wear a standard mouthguard over bare teeth during play. This removes the bracket-related complexity. Store aligners in a protective case during sport and reinsert them immediately after cleaning your teeth. For non-contact activity, aligners can be worn throughout without additional protection. Is a mouthguard available on the NHS with braces? Custom orthodontic mouthguards are not routinely available on the NHS. They are provided privately by dentists and orthodontists, typically costing £50 to £150 in the UK. Some orthodontic practices include a custom guard as part of a treatment package for patients in contact sport — ask whether this is available when your treatment begins. How do I clean my mouthguard when I have braces? Rinse the guard in cold water immediately after use. Clean it with a soft toothbrush and mild soap, concentrating on the bracket-contact areas where plaque accumulates. Allow it to air-dry before storing. Do not use hot water, which warps thermoplastic material, and avoid soaking in alcohol-based mouthwash for extended periods, as this degrades the guard material. Replace the guard when it shows wear or no longer fits well due to tooth movement. Which sports require a mouthguard with braces in the UK? The RFU recommends mouthguards for all rugby players. England Hockey recommends them for all levels. Boxing and martial arts governing bodies mandate custom guards in competitive settings. Lacrosse, American football, and water polo also carry significant facial impact risk. For fixed brace wearers, an orthodontic custom guard should be used in any sport with collision, contact, or the possibility of facial impact — not just the sports where governing bodies formally require it. Can I use a mouthguard instead of a retainer after treatment? No. A sports mouthguard or night guard is not a substitute for an orthodontic retainer. Retainers are made to hold each tooth in its corrected position, whereas a mouthguard is bulkier, fits less precisely and does not control tooth position, so teeth can drift if it is worn in place of a retainer. If you need protection for sport or grinding after treatment, keep wearing your retainer as instructed and use a separate guard when needed, or ask your orthodontist whether a combined design suits your case. Can my orthodontist arrange a mouthguard on the NHS if I play contact sport? A custom sports guard is not a standard part of NHS orthodontic treatment, but it is worth asking. If you or your child plays contact sport regularly, raise it at the assessment or bracket-fitting appointment rather than assuming it is included or excluded. The orthodontist can advise whether a guard is clinically needed, suggest an orthodontic boil-and-bite guard as a stop-gap, or point you to your general dentist or a private provider. Ask before the sporting season starts so a guard is ready in time. Explore your options Quick links Not sure where to start?
