A custom fitted sports mouthguard is the single most effective way to prevent dental injury during contact sport, and it performs substantially better than a store bought version. Dental injuries in sport are common, often permanent, and almost entirely preventable, which puts a mouthguard firmly in the category of essential equipment rather than optional accessory. Having a professionally made sports mouthguard fitted takes two short appointments and lasts a full season or more.
The reason custom guards work better is straightforward. They are made from a model of your own teeth, so thickness is placed where impact energy actually needs absorbing, and the guard stays in place without being bitten to hold it.
Grinding guards are a different appliance entirely and are frequently confused with sports guards. A nightguard is designed for sustained clenching forces during sleep, not for sudden impact.
When an injury does happen, chipped front teeth are the most common outcome. Dental bonding restores a chipped edge in a single visit with tooth coloured resin.
More significant fractures need coverage rather than a facing, and caps and crowns rebuild teeth that have lost substantial structure.
A knocked out tooth is genuinely time critical, so knowing how to reach emergency dentistry before the season starts is worthwhile preparation.
If your child plays contact sport or you have started noticing worn front teeth, request an appointment to have a custom guard made before the next game.
Why Sports Mouthguards Matter
Dental trauma accounts for a significant proportion of all sports injuries, and the upper front teeth take the majority of impacts. Unlike a bruise or a sprain, a lost adult tooth does not heal. It requires lifelong restorative care.
A properly fitted mouthguard works through several mechanisms:
- Distributing impact force across a wider area rather than a single tooth
- Absorbing and dissipating energy within the material
- Cushioning the lower jaw against the upper, reducing the risk of jaw fracture and joint injury
- Preventing lacerations to the lips, cheeks and tongue
- Separating the jaws slightly, which may reduce concussive force transmitted through the mandible
A note of accuracy on that final point. Evidence that mouthguards reduce concussion risk is suggestive rather than conclusive, and no mouthguard should ever be presented as concussion protection. What is well established is their effectiveness against dental and soft tissue injury.
Which Sports Need a Mouthguard?
High Risk
- Hockey, boxing, martial arts, rugby, football, lacrosse
- Wrestling, water polo, field hockey
Moderate Risk, Often Overlooked
- Basketball, which produces a surprisingly high rate of dental injury from elbows
- Soccer, particularly during heading and goalkeeping
- Baseball and softball
- Skateboarding, BMX, mountain biking and skiing
- Gymnastics, volleyball and weightlifting where clenching is heavy
Anyone wearing braces should use a mouthguard for any sport with contact potential, because brackets and wires can cause serious soft tissue laceration on impact.
Types of Mouthguard Compared
| Type | Fit | Protection | Comfort and speech | Lifespan |
|---|---|---|---|---|
| Stock, ready to wear | Poor, one size | Low | Bulky, must be held by biting | Short |
| Boil and bite | Approximate | Moderate | Variable, thins in wrong places | One season at best |
| Custom laboratory made | Precise | Highest | Comfortable, speech barely affected | One to several seasons |
| Pressure laminated custom | Precise, multi layer | Highest, for elite contact sport | Excellent retention | Longest |
Why Boil and Bite Guards Underperform
- Softening and biting thins the material exactly where impact protection is needed most, over the front teeth
- Retention relies on clenching, so the guard loosens as soon as the athlete opens their mouth to breathe or speak
- Coverage of the back teeth is often inadequate, reducing jaw cushioning
- They cannot accommodate braces, mixed dentition or an unusual bite
- Poor fit encourages athletes to remove them, and a guard in a pocket protects nothing
How a Custom Mouthguard Is Made
- Assessment. Teeth, bite, gum health and any orthodontic appliances are examined. Existing decay is treated first.
- Impression or digital scan. An accurate record of both arches and the bite relationship is captured.
- Sport specific specification. Thickness, extension and layering are chosen according to the sport and level of contact.
- Laboratory fabrication. The guard is formed over a model of your teeth, often using pressure lamination for higher risk sports.
- Fitting appointment. Retention, coverage, edges and comfort are checked and adjusted.
- Instruction. You are shown how to insert, remove, clean and store it, and when to have it reviewed.
Children and teenagers need reassessment more often, because teeth continue to erupt and jaws continue to grow. A guard that fitted last season may not fit this one.
Mouthguards Versus Nightguards
| Feature | Sports mouthguard | Nightguard |
|---|---|---|
| Purpose | Absorb sudden impact | Manage sustained grinding and clenching |
| Material | Softer, energy absorbing, thicker | Harder or dual layer, wear resistant |
| Coverage | Usually upper arch, full occlusal coverage | Upper or lower, precise bite contact |
| When worn | During training and competition | During sleep |
| Replacement | Each season or as growth dictates | Typically every few years |
The two are not interchangeable. A soft sports guard worn nightly will be chewed through quickly and may even encourage clenching, while a hard nightguard offers little impact absorption and can fracture teeth under a blow.
Caring for a Mouthguard
- Rinse with cool water before and after every use
- Clean with a soft brush and mild soap or a non abrasive cleaner, never hot water
- Allow it to dry fully before storing
- Store in a ventilated case, never in a sealed bag or a hot car
- Keep it away from pets, which are a surprisingly common cause of loss
- Never chew, trim or reshape it yourself
- Bring it to dental appointments so fit and wear can be checked
- Replace it if it becomes torn, thin, distorted or persistently loose
Heat is the main enemy. Leaving a guard on a dashboard or rinsing it in hot water permanently distorts the fit.
Myths About Mouthguards
Myth: mouthguards are only needed in hockey and boxing. Basketball and soccer generate high numbers of dental injuries because contact is incidental and unexpected.
Myth: they make it impossible to breathe or talk. Poorly fitted guards do. A custom guard covers only what it needs to and most athletes adapt within a session.
Myth: children with baby teeth do not need one. Baby teeth guide permanent teeth into position, and injuries to them can damage the developing adult tooth underneath.
Myth: any guard is as good as another. Protection depends on thickness in the right places and reliable retention, which is precisely what custom fabrication provides.
Myth: braces mean you cannot wear a mouthguard. The opposite is true. Patients with braces need protection most, and guards can be designed to accommodate appliances.
What to Do If a Dental Injury Happens
Knocked Out Permanent Tooth
- Pick the tooth up by the crown only, never the root
- Rinse briefly in milk or saline if dirty. Do not scrub
- Reinsert it into the socket immediately if possible and bite gently on gauze
- If reinsertion is not possible, store it in milk, never water
- Seek dental care within the hour, since time is the biggest factor in success
Chipped or Fractured Tooth
- Save any fragment in milk or saline
- Rinse gently with warm water and control bleeding with clean gauze
- Apply a cold compress externally
- Cover a sharp edge with dental wax or sugar free gum
- Arrange assessment promptly, even if there is no pain
Jaw Injury
If the bite feels misaligned, the jaw cannot open or close properly, or there is significant swelling, seek urgent assessment and consider hospital review for suspected fracture.
Patient Scenarios
A Teenage Hockey Player With Braces
A boil and bite guard cannot fit over brackets and keeps dislodging. A custom laminated guard designed with space for the appliance provides reliable protection and stays in place through a shift.
A Basketball Player Who Never Wore One
An elbow to the mouth chips two upper incisors. Bonding restores both edges in one visit, and a custom guard is made afterwards. Reviewing the nerve health of both teeth at six months is part of the plan, because trauma can affect a nerve months later.
A Growing Child Between Seasons
A guard made eighteen months ago no longer seats properly because permanent teeth have erupted. Reassessment and a new guard are needed, which is normal rather than a fault with the original.
An Adult Who Grinds and Plays Rugby
Two separate appliances are made, because the material requirements are entirely different. Using one for both purposes would compromise protection in each situation.

Frequently Asked Questions
Is a custom mouthguard really better than a boil and bite version?
Yes, and the difference is measurable. Custom guards are formed over a model of your own teeth, so material thickness is retained exactly where impact protection is needed. They also stay in place without clenching, which means athletes actually keep them in rather than removing them to breathe or communicate.
Can I use my sports mouthguard for teeth grinding at night?
No. Sports guards use softer, thicker material designed to absorb sudden impact, and sustained nightly clenching will chew through them within months. Some patients also find that biting into a soft guard encourages more clenching. A nightguard uses harder, wear resistant material with precise bite contact.
How often should a mouthguard be replaced?
Adults typically get one to several seasons from a custom guard, depending on the sport and how heavily they clench. Children and teenagers usually need reassessment every season or two because teeth are still erupting and jaws are growing. Replace any guard that is torn, thin, distorted or persistently loose.
Do mouthguards prevent concussion?
No mouthguard should be marketed or relied upon as concussion protection. Some evidence suggests that separating the jaws may reduce force transmitted through the mandible, but this is not conclusive. What is well established is that properly fitted guards markedly reduce dental fractures, tooth loss and soft tissue injuries.
Can children with baby teeth wear a mouthguard?
Yes, and they should for any contact sport. Injuries to primary teeth can damage the permanent teeth developing beneath them and can affect arch space. Guards for children are made to accommodate mixed dentition and are reviewed more frequently as new teeth erupt.
Conclusion
A custom fitted sports mouthguard is inexpensive protection against injuries that are permanent and expensive to repair. Store bought versions thin out exactly where they are needed and are far more likely to be left out of the mouth. Fitting a guard before the season starts, and replacing it as children grow, prevents the majority of sports related dental trauma.
