Invisalign in Rugby · the honest guide
Can you play rugby with Invisalign? Aligners, mouthguards and match day
Written by Dr Jasmeet Heran, Invisalign dentist at Rugby Smiles · Reviewed September 2026
The short answer: yes, you can play. No, you cannot play in them. Being a dental practice in Rugby, we get asked this more than most. Invisalign does not stop you playing rugby, but an Invisalign aligner is not a sports mouthguard, and for contact rugby we want the aligners out and a proper protective mouthguard in.
The real question for players is not safety, it is hours. Invisalign only works while it is in your mouth, and a training night plus a match is time the aligners are out. Here is how to handle both without falling behind.
Need a mouthguard first? Custom sports mouthguards, £150
Why an aligner is not a mouthguard
An aligner is a thin, precisely fitted shell designed to push teeth in small, planned steps. A mouthguard is a thick, shock-absorbing layer designed to spread an impact across the teeth and jaw. They are built for opposite jobs. Wear an aligner into a tackle and the best case is a cracked aligner; the worst case is the injury the mouthguard would have prevented.
Do not wear a mouthguard over the aligners either. It is moulded to your teeth, not to a layer of plastic on top of them, so it will not seat, and the aligners can crack underneath it.
“Invisalign does not stop you playing rugby, but an Invisalign aligner is not a sports mouthguard. For contact rugby, I would want the aligners removed and an appropriate protective mouthguard worn. I would not rely on the aligner to protect the teeth from an impact.”
Dr Jasmeet Heran, Rugby Smiles
Training nights and match day: the 22-hour maths
Aim for around 22 hours of wear a day. A two-hour training session with the aligners out still leaves you inside that on a normal day, provided they go straight back in afterwards. A match day with warm-up and travel eats more, which is fine occasionally. What is not fine is the pattern: aligners out at five, forgotten until bedtime, three nights a week.
1
Before you leave
Aligners in until as close to training as practical. Brush if you can, and put the case in your kit bag, not your pocket.
2
Aligners out, guard in
Straight into the case. Never a tissue, never the bench. Wear the custom mouthguard for the whole session, warm-up included.
3
Straight afterwards
Rinse or brush, then aligners back in before the drive home. Not after food, not after the club bar.

Keep the count honest
An hour or two occasionally is nothing. Regular long gaps are what push a case behind its plan.
“Missing an hour or two occasionally is not going to ruin treatment, but regularly leaving the aligners out for long periods can.”

A custom mouthguard, made here, £150
A boil-and-bite guard from the sports shop is better than nothing, but it is bulky, it moves, and it is the reason players take guards out mid-match. A custom guard is made to a scan or impression of your teeth, so it stays put and you can talk and breathe in it. We make them at the practice for £150. Sports mouthguards and gum shields in Rugby has the detail.
One thing that is specific to Invisalign players: your teeth are moving, so a guard made at the start of treatment will fit differently a few months in. Tell us when it starts to feel loose and we will check it. Fitting the guard at the same visit as your first aligners is the simplest way to start.
If an aligner cracks
Aligners crack far more often in kit bags than in mouths. If one does, ring us rather than carrying on with it. Depending on where you are in the sequence we may move you to the next aligner early, back to the previous one for a few days, or order a replacement. What we do not want is a cracked aligner worn for a fortnight while the tooth it was moving drifts.
“Do not wrap your aligners in a tissue and leave them in the changing room. That is how expensive aligners end up in the bin.”

Fixed braces and rugby, for comparison
Players sometimes assume fixed braces are the safer choice because they cannot be lost. They stay in during a match, which means a knock can drive a bracket into the lip, so they need a special orthodontic mouthguard and a bit of luck. Aligners come out and a normal custom guard does the job. Neither is wrong; our comparison of every teeth-straightening option sets out the trade-offs, and fixed braces remain the right call for some cases whatever sport you play.
Questions players ask
Can I wear my Invisalign aligners while playing rugby?
Not for contact rugby. An aligner is not a mouthguard and will not protect your teeth from an impact. Take the aligners out, put them in their case, and wear a proper protective mouthguard.
Can I wear a mouthguard over my aligners?
No. A mouthguard is moulded to fit your teeth, not your aligners, so it will not seat properly over them, and the aligners can crack under it. Aligners out, mouthguard in.
Will taking them out for training ruin my treatment?
Missing an hour or two occasionally will not. Regularly leaving the aligners out for long periods can, because Invisalign only works while it is in your mouth. Take them out as close to kick-off as practical and put them straight back in afterwards.
Do I need a special mouthguard for Invisalign?
You need a custom mouthguard made to your teeth. Because your teeth are moving, the fit changes during treatment, so tell us when it starts feeling loose and we will check it. We make custom sports mouthguards at the practice for £150.
What if I crack an aligner?
Ring us. Depending on where you are in the sequence we may move you to the next aligner, back to the previous one, or order a replacement. Do not carry on wearing a cracked aligner.
Are fixed braces better for rugby players?
Not necessarily. Fixed braces stay in during a match and need a special orthodontic mouthguard; a knock can drive brackets into the lip. Aligners come out and a normal custom mouthguard does the job. Both work; it comes down to your case and how you live.
