Custom Sports Mouthguards in St. John's: Protect Your Smile
- Jun 21
- 9 min read
Roughly 39% of all dental injuries happen during sports and recreational activities, according to the Canadian Dental Association. If you play hockey, soccer, martial arts, or even recreational rugby here in St. John's, your teeth are at risk every single time you step onto the ice or field without proper protection. A pharmacy-bought boil-and-bite tray is not adequate protection. A custom sports mouthguard in St. John's, fitted by a dental professional at a practice like Stavanger Dental, is the standard of care that actually works. This article breaks down exactly why, and what to do about it before summer sports season peaks.

Key Insight
Explanation
Custom mouthguards reduce injury risk significantly
Dentist-fitted mouthguards cover teeth precisely, absorbing and distributing impact forces that store-bought trays cannot handle.
Boil-and-bite trays offer minimal real protection
They thin out over molars, leave gaps at the front, and often fall out during contact, defeating their entire purpose.
St. John's summer sports season spikes injury rates
Baseball, soccer, rugby, and cycling all carry orofacial injury risks that peak from May through August in Newfoundland.
One knocked-out tooth costs far more than a custom guard
A dental implant in NL can run $3,000 to $5,000 per tooth. A custom mouthguard costs a fraction of that and lasts 3 to 5 years with proper care.
Children and teens need custom guards too
Developing teeth and jaws are especially vulnerable. Stavanger Dental serves patients of all ages, making custom guards accessible for the whole family.
Canadian Dental Care Plan may offset costs
Stavanger Dental accepts the Canadian Dental Care Plan, which can reduce out-of-pocket costs for eligible patients seeking preventive dental devices.
Orthodontic patients need specialized guards
If you or your child is in Invisalign or braces, a standard mouthguard will not fit correctly. A custom guard accommodates orthodontic hardware safely.
Why Mouthguards Matter More Than Most Athletes Think
Most recreational athletes in St. John's underestimate orofacial injury risk. They budget for helmets, shin guards, and proper footwear, then skip the mouthguard entirely or toss a $12 boil-and-bite tray into their bag as an afterthought. That is exactly how teeth get broken.
The Canadian Dental Association reports that mouthguards prevent an estimated 200,000 dental injuries per year in North America. The injuries they prevent include chipped and fractured teeth, avulsed (knocked-out) teeth, jaw fractures, and lacerations to lips and cheeks. These are not minor inconveniences. A fractured tooth can require a crown. A knocked-out permanent tooth requires an implant, a bridge, or goes unreplaced permanently.
In practice, the patients who come in with sports-related dental trauma almost always say the same thing: they were not wearing a guard because it felt uncomfortable or they forgot it at home. A properly fitted custom mouthguard NL athletes wear consistently is worth far more than a perfect guard sitting in a gym bag.
"Orofacial injuries account for approximately 10 to 39 percent of all dental injuries, and athletes are among the highest-risk populations. The evidence strongly supports mandatory mouthguard use in contact sports." - American Dental Association, Position Statement on Athletic Mouthguards
Comfort drives compliance. A guard that fits well gets worn. That is the single biggest practical argument for going custom instead of reaching for whatever is on the shelf at a sports store.
Custom vs. Store-Bought: The Real Difference
The mouthguard market breaks down into three categories: stock trays, boil-and-bite trays, and custom-fitted guards made by a dental professional. The first two are available at any Canadian Tire or pharmacy in St. John's. The third requires a dental appointment and impressions or a digital scan of your teeth.
Why Stock and Boil-and-Bite Guards Fall Short
Stock trays come in small, medium, and large. They do not conform to anyone's teeth specifically, which means they rely on you biting down to stay in place. You cannot speak clearly while wearing one, and the fit at the margins is poor. Boil-and-bite versions do allow some adaptation to your tooth shape, but the thermoplastic material thins out significantly over the back molars when you bite down into it during molding. Those molars are left with inadequate coverage.
A common mistake is assuming that any coverage is sufficient coverage. It is not. A guard that is too thin at the molars will transmit impact force directly to your jaw joint and upper arch, which is worse than the guard's mere presence would suggest.
What a Dentist-Made Guard Actually Provides
A custom mouthguard produced through a dental office like Stavanger Dental starts with accurate impressions or a digital scan of your upper arch. A dental laboratory then fabricates the guard from pressure-laminated ethylene vinyl acetate, typically in layers, with uniform thickness across all surfaces. The result is a guard that stays in place without biting, allows normal speech, and distributes impact load evenly across all teeth and the jaw.
For dental protection athletes in St. John's need during serious contact sports, this is not optional equipment. It is the minimum viable standard.
Pro tip: If you are currently in Invisalign treatment at Stavanger Dental, ask about a sports guard that fits over your aligners or replaces them during athletic activity. Aligners alone do not provide adequate impact protection.
Sports in St. John's That Require Dental Protection
Newfoundland's summer sports calendar is packed. From late April through August, St. John's residents are out in force for soccer leagues at Swilers Rugby Park, recreational hockey at ice rinks that run year-round, mountain biking on Signal Hill area trails, martial arts training, and organized baseball and softball leagues across the city.
Contact Sports with Mandatory or Strongly Recommended Guards
Hockey is the obvious one. Hockey Canada strongly recommends mouthguards for all levels of play. But rugby and martial arts carry statistically higher rates of orofacial trauma per participant hour than hockey does. Basketball, often overlooked, is among the top sports for dental injury in North America because players underestimate elbow and head contact in a non-collision sport.
Non-Contact Sports Where Guards Still Make Sense
Cycling in St. John's means hills, wind, and uneven pavement. Falls from bikes are a consistent source of dental trauma. Gymnastics and cheerleading involve aerial activity and partner work that creates real fall risk. Even recreational flag football on the Bannerman Park fields carries risk if you are diving for a catch on hard ground.
The data consistently shows that dental injuries happen in sports people do not typically associate with mouth risk. A custom mouthguard is a low-cost, high-value piece of protective equipment for any sport where a fall or collision is possible, which is nearly all of them.
What to Expect When Getting a Custom Mouthguard at Stavanger Dental
Getting a custom mouthguard at Stavanger Dental is a straightforward process that typically requires two short appointments. The first involves an examination and impressions or a digital scan of your upper teeth. The second is the fitting appointment, where you try the finished guard, confirm the fit across all surfaces, and make any minor adjustments needed.
The Impression and Fabrication Process
Stavanger Dental uses dental impressions to capture the precise contour of your upper arch. Those impressions are sent to a dental lab where a custom guard is fabricated under pressure to ensure uniform thickness and a snug fit at the gum margins. The typical turnaround is one to two weeks, which is worth planning for before your sports season starts rather than after an injury has already occurred.
Options for Children and Teens
Stavanger Dental is a family dental office, and custom guards for young athletes are a regular part of the practice. One important note for parents: children's mouths change as they grow. A guard fitted during a significant growth period may need to be replaced within a year. This is especially true for patients between ages 10 and 15. The replacement cost is still far lower than treating a fractured or avulsed tooth in a developing permanent dentition.
Families enrolled in the Canadian Dental Care Plan should ask Stavanger Dental's team about coverage options for preventive dental devices during their consultation. Every dollar of coverage applied to a custom guard is a dollar not spent on future restorative work.
Pro tip: Book your custom mouthguard appointment at Stavanger Dental before May, when St. John's summer sports registrations peak and appointment slots fill up. Waiting until mid-season means you are playing unprotected in the meantime.
Mouthguard Options Compared
Not every athlete has the same needs or budget, but the comparison below shows clearly where value lies when you account for protection, durability, and long-term cost.
Mouthguard Type
Protection Level and Fit
Cost and Lifespan in NL Context
Stock / Ready-Made Tray
Poor fit, minimal impact absorption, requires biting to stay in place, nearly impossible to speak normally
$5 to $15 at local retailers. Lifespan of one season at best. No dental professional involvement.
Boil-and-Bite (e.g., Shock Doctor)
Moderate fit when molded correctly, but thinning over molars is a consistent problem. Falls out during intense play.
$20 to $50. Needs replacement every season. Better than nothing but well below clinical standard.
Custom Dentist-Fitted Guard (Stavanger Dental)
Precise fit, uniform thickness, stays in place without biting, allows clear speech, highest impact distribution
Typically $200 to $500 depending on complexity. Lasts 3 to 5 years with proper care. Canadian Dental Care Plan may offset cost.
Caring for Your Custom Mouthguard
A custom mouthguard is an investment in your dental health, and it needs basic maintenance to remain hygienic and effective. The most common reason a custom guard degrades early is poor storage and cleaning habits, not the quality of the guard itself.
Daily Cleaning Routine
Rinse your guard with cold water immediately after use. Clean it with a soft toothbrush and mild soap, not toothpaste. Toothpaste is abrasive enough to scratch the EVA material over time, creating surface texture where bacteria colonize. After cleaning, allow the guard to air dry completely before storing it in its hard case. Never leave it in a hot car in summer, as the material will warp.
When to Replace Your Guard
Signs that a custom mouthguard needs replacing include visible cracks, tears, or thinning of the material, a loose fit that was not there when the guard was new, or a persistent odor that does not resolve with cleaning. Children and teens in active growth should have their guards checked at every dental visit at Stavanger Dental to confirm fit is still accurate.
Bring your mouthguard to your routine checkups. The team at Stavanger Dental can assess wear and let you know whether the current guard is still providing the protection it was made to provide, or whether it is time to update it. This is the kind of proactive preventive care that the practice is built around, and it takes less than two minutes during an existing appointment.
Frequently Asked Questions
How much does a custom sports mouthguard cost in St. John's?
Custom mouthguards at dental offices in St. John's, including Stavanger Dental, typically range from $200 to $500 depending on the complexity of your case and the materials used. This is significantly more than a pharmacy option, but the durability, protection level, and fit justify the cost, especially when you compare it to the price of repairing a single damaged tooth. Patients enrolled in the Canadian Dental Care Plan should ask about applicable coverage.
Can I get a custom mouthguard if I am wearing Invisalign?
Yes. Stavanger Dental offers Invisalign as part of its orthodontic services, and patients in active aligner treatment should not rely on their aligners for sports protection. A custom mouthguard can be made to fit over your current aligner stage, or your provider can advise on the safest approach for your specific treatment phase. Do not play contact sports wearing only your aligners.
At what age should children start wearing a custom mouthguard?
As soon as a child begins participating in contact or collision sports, a mouthguard is appropriate. Stavanger Dental fits custom guards for young patients regularly. Once primary teeth have been replaced by permanent teeth, typically around age 6 to 12, the case for a custom fit becomes even stronger. Guards for children may need more frequent replacement due to jaw growth, but they are worth it.
Is a mouthguard necessary for non-contact sports like cycling or basketball?
Yes. Basketball consistently ranks in the top five sports for dental injuries in North America, despite being classified as non-contact. Cycling falls are a well-documented source of facial trauma. The mouthguard decision should be based on fall risk and elbow or equipment contact risk, not just whether the sport is officially labeled contact. If you can fall or be struck in the face, a mouthguard belongs in your kit.
How long does it take to get a custom mouthguard made at Stavanger Dental?
The process typically takes two appointments over one to two weeks. The first appointment covers impressions or a digital scan and usually takes 30 minutes or less. The lab then fabricates the guard and returns it to the practice. The second appointment is a short fitting session. Planning ahead before your sports season starts is strongly recommended, as wait times can extend in peak season.
Does a custom mouthguard help with jaw clenching during sports?
Yes. Many athletes clench their jaw during intense exertion, which puts stress on teeth and the temporomandibular joint. A well-fitted custom mouthguard cushions the bite during clenching, reducing wear on tooth surfaces and minimizing jaw joint strain. If you already grind or clench at night, discuss this with the Stavanger Dental team, as the same impression data may inform both a sports guard and a night guard solution.
