Yes, a young athlete with braces should wear a mouthguard for every practice and game. It needs to be an orthodontic guard designed to fit over brackets, not a standard boil-and-bite moulded to the teeth.
Why Do Kids With Braces Need a Different Mouthguard?
A conventional boil-and-bite guard works by taking the exact shape of the teeth. Braces change that shape every few weeks, so a moulded guard either stops fitting, or grips the brackets hard enough to pull them off during impact. An orthodontic guard is made from softer, roomier material that covers the appliance instead of locking onto it.
There is a second reason. A hit to the mouth in a braces case is not only a risk to the teeth; the brackets and wires themselves can cut the lips and cheeks. A guard that sits between the appliance and the soft tissue prevents the injuries we see most often after contact sports.
Which Type of Mouthguard Should You Buy?
There are three broad categories, and only two of them belong in a braces case.
Stock Guards
Inexpensive, ready to wear, and bulky. They rarely stay in place without clenching, and children tend to spit them out. Better than nothing in an emergency, not a season-long answer.
Orthodontic Guards
Sold specifically for braces, made of high-density but flexible material, and sized to fit over brackets without gripping them. For most children in braces treatment this is the practical choice, because it keeps working as the teeth move.
Custom Guards Made From an Impression or Scan
The best fit, the most comfortable, and the easiest to breathe and speak through, which is exactly why children actually keep them in. Because teeth move during orthodontic treatment, timing matters: ask us whether to fit a custom guard now or after your appliance comes off.
How Do the Options Compare for a Child in Braces?
| Guard type | Fit with braces | Best for | Worth knowing |
|---|---|---|---|
| Stock | Loose and bulky | A forgotten guard on game day | Hard to talk and breathe through, easily spat out |
| Boil-and-bite | Poor once brackets are on | Athletes without braces | Moulding to brackets can pull them loose |
| Orthodontic (braces-specific) | Designed to sit over brackets | Most kids and teens in braces | Keeps fitting through adjustments; replace when it tears or thins |
| Custom-made | Excellent | Frequent contact sport, retainers, post-treatment | Needs remaking if teeth are still moving |
Which Sports Actually Need a Guard?
Any sport with a ball, a stick, a puck, or another body in motion. Football and hockey are obvious. So are basketball, soccer, lacrosse, baseball, softball, wrestling, martial arts, skateboarding and mountain biking, which produce plenty of mouth injuries precisely because families assume a guard is not needed.
One rule beats every list: if it is worn for the game, it is worn for practice. Practices take up more hours than games do, and collisions do not check the schedule first.
How Should Your Child Wear and Care for It?
Getting It In and Keeping It In
The guard covers the upper teeth and brackets. If your child has an appliance on the lower arch too, ask us about a double guard. Expect a few sessions of adjustment: speech feels odd at first, and that fades. If the guard is being chewed, cut, or constantly removed, it is the wrong size and we should look at it.
Cleaning It So It Lasts a Season
- Rinse with cool water before and after every use
- Brush it gently with a toothbrush and a little soap or toothpaste, then air-dry
- Store it in a vented case, never loose in a bag or a pocket
- Keep it out of hot water, dishwashers, and car dashboards, which warp it permanently
- Replace it when it tears, thins, or stops covering the brackets
The same brushing habits that protect teeth under brackets protect the guard. Our life with braces care tips cover the routine we recommend at home.
When Should a Custom Guard Be Made During Orthodontic Treatment?
Timing is the part families get wrong. A custom guard is made to the shape of the teeth on the day it is taken, and teeth in active treatment keep moving, so a guard made in month two of braces may not seat properly by month eight. Two approaches work.
The first is to use a well-fitting orthodontic guard through active treatment and have a custom guard made once the appliance comes off, at the same stage as the retainer. The second, for children in a long or high-contact season, is to accept that a custom guard made mid-treatment will need remaking. Ask us at your next adjustment and we will tell you which makes sense for your child’s stage of orthodontic treatment.
What About Retainers and Aligners on the Field?
Retainers and aligners are not protective equipment. Both are thin, rigid, and made to fit precisely, which is the opposite of what absorbs an impact. Take the retainer or aligner out, put it in its case, wear the mouthguard, and put the appliance back in straight after the whistle. Leaving a retainer loose in a bag or wrapped in a napkin is how most of them are lost or thrown away.
How Do You Get a Child to Actually Wear It?
Compliance is the whole game. A guard in the bag protects nothing.
- Let your child choose the colour; it costs nothing and it matters at that age
- Keep the case clipped to the sports bag, not in the bathroom
- Make it a rule for practice as well as games, so it never becomes a decision
- Fix the fit rather than arguing about it: chewing and gagging mean the wrong guard, not a difficult child
- Ask the coach to check guards at warm-up, the way helmets get checked
What Should You Do If There Is a Mouth Injury Anyway?
Guards reduce injuries, they do not abolish them. If a hit does damage, act on what you can see. Control bleeding with clean gauze and firm pressure. Use a cold compress on the lip or cheek. If a bracket has come loose or a wire is cutting, cover it with orthodontic wax and call our Allen office. If a permanent tooth is knocked out, keep it wet, hold it only by the crown, and contact our pediatric emergency dentistry team immediately, because those first minutes matter. Head to an emergency room for a suspected facial fracture, bleeding you cannot control, or trouble breathing or swallowing.
Does Sizing Matter for a Growing Child?
It matters more than brand. Guards are usually sold in a youth size and an adult size, and the youth size is built for a smaller arch with fewer permanent teeth. A child in the middle of the mixed-dentition years, with baby teeth and permanent teeth side by side, often sits awkwardly between the two.
Two practical tests. First, the guard should cover every upper tooth and the brackets on them, ending behind the last molar without pressing into the gum. Second, your child should be able to close their lips over it and speak understandably. If either fails, size up or move to a custom guard rather than trimming it aggressively, which removes the material that absorbs impact.
Helmets and face cages do not replace a guard, either. A cage stops a stick or a ball reaching the face; it does nothing about the lower jaw being driven into the upper teeth, which is the injury a guard is designed for.
Frequently Asked Questions About Mouthguards and Braces
Can my child wear their old boil-and-bite guard over new braces?
No. It was moulded to teeth without brackets, so it no longer fits and it can pull brackets off on impact. Switch to an orthodontic guard when the braces go on.
Do kids in clear aligners need a mouthguard too?
Yes, and aligners are not a substitute for one. Take the aligner out for contact sport, wear the mouthguard, then put the aligner back in afterwards so wear time stays on track.
How often should we replace an orthodontic mouthguard?
Check it monthly. Replace it when the material is torn, thinning, chewed through, or no longer covers the brackets, and at the start of each new season for a growing child.
Does a mouthguard help with grinding at night?
A sports guard is built for impact, not for night-time grinding. If your child grinds, tell us at their next visit and we will look at the wear pattern before recommending anything.
