The link between teeth and wind instruments runs in both directions. Hours of embouchure work can nudge tooth position a little, and the position of your teeth can make playing more or less comfortable. The research on both is thin, so most of what matters day to day is practical: protecting the lips, planning orthodontic treatment around your playing, and telling your dentist what you play.
The evidence that playing moves teeth is weak
A 2020 systematic review and meta-analysis by van der Weijden and colleagues in the Journal of Orofacial Orthopedics pooled ten studies of wind players and non-players. Adults who played a single-reed instrument such as clarinet or saxophone tended to have a slightly larger overjet, the horizontal gap between the upper and lower front teeth. Children who played brass showed a small reduction in overjet over follow-up periods of six months to three years. The authors described the size of these effects as of questionable clinical relevance and rated the overall strength of the evidence as very low.
So playing may have a small influence on how the front teeth sit, but it is not a reason for a child to give up an instrument, and it does not mean a player's bite will change in a noticeable way.
Your bite can affect how you play
The same research group also looked at the question the other way round. Their 2018 review found only four small studies, but they pointed the same way: a large overjet may get in the way of a brass embouchure, and very wide spaces or an open bite can make any wind instrument harder to play. The authors concluded that an even bite without major crowding or gaps seems to suit every type of wind instrument, while noting that evidence is limited. A chipped or uneven front tooth can also change how a mouthpiece sits, which is one reason musicians often notice small dental changes before anyone else does.
Brass, reed and flute players load the mouth differently
Trumpet, horn, trombone and tuba players press a metal rim against the lips, which are in turn supported by the front teeth. Clarinet and saxophone players rest the reed on the lower lip, which covers the lower front teeth, with the upper teeth resting on the mouthpiece. Flute players rest the lip plate against the chin just below the lower lip and blow air across the embouchure hole, so there is much less direct pressure on the teeth. These differences explain why reed players, brass players and flautists tend to report different patterns of lip soreness and different worries about their teeth.
Sore lips and the mouthpiece contact point
Tenderness, a firm thickened patch, or the odd small cut on the inner lip after a long rehearsal is common among brass and reed players. Much of this is friction and pressure rather than a dental problem, and a music teacher can sometimes help with mouthpiece placement or pressure. Mention it to your dentist if a sore has not healed or changed within 3 weeks, if one spot keeps breaking down, or if the gum at the contact point starts to recede. A rough or chipped tooth edge under the lip is easy to smooth, so it is worth having checked.
Braces and aligners when you play
Fixed braces put brackets between the lips and the teeth. Many players find the first few weeks uncomfortable and need time to adjust their embouchure, so starting treatment, or booking adjustments, away from auditions and major performances can help. Orthodontic wax over the brackets is a common short-term aid.
Clear aligners are smooth, and many musicians take them out to play. The catch is wear time: aligner makers usually instruct patients to wear them for about 20 to 22 hours a day, so long practice sessions eat into that time. Some players can play with aligners in after a period of getting used to them. Lumi provides both fixed braces and clear aligners, and telling us your instrument and weekly playing hours at the first consult lets us factor them into the plan.
A sports mouthguard is not made for playing
A mouthguard covers the upper teeth with a thick layer, which changes lip support and the shape of the mouth, so it is not practical to wear while playing. If you play a contact sport as well, a custom-fitted guard for sport is still worth having; custom guards fit better and are more comfortable than boil-and-bite guards, although evidence that they prevent more injuries is limited. If you grind or clench your teeth at night, a night splint is a different appliance with a different purpose. Our article on teeth grinding in adults explains how splints are used.
Mouth breathing and a dry mouth
Playing involves long stretches of breathing in through the mouth, and many players notice their mouth feels dry after a rehearsal. Saliva helps buffer acid and rinse the teeth, so it makes sense to sip water during breaks, keep sugary drinks and lollies out of rehearsal time, and brush twice a day with fluoride toothpaste. If your mouth feels dry much of the time, even away from playing, our guide to dry mouth covers other causes worth checking.
What to mention at your check-up
Tell your dentist or OHT which instrument you play, roughly how many hours a week, and when your next big performance is. Point out anything you have noticed, such as a sore spot on the lip, a tooth that feels different against the mouthpiece, or jaw tiredness after playing. Jaw muscle fatigue and clenching often travel together, and our article on clenching and headaches may be useful if that sounds familiar.
Common questions
Will my child's teeth move if they learn the trumpet?
Studies have found only small changes in tooth position among young brass players, of uncertain clinical importance. Learning an instrument is not considered a reason for orthodontic concern on its own.
Can I keep playing during orthodontic treatment?
Usually, yes. Expect an adjustment period with fixed braces, and plan around big performances where you can. With aligners, keep track of how long they are out of your mouth each day.
Do reed players have the same problems as brass players?
The pressure points differ. Reed players load the lower lip against the lower teeth, while brass players press the rim against both lips, so the sore spots and the dental questions tend to differ too.
If you play and would like your teeth, lips and bite looked at with your instrument in mind, the team at Lumi Dental in Melrose Park is happy to help. You can book a check-up or see the current new patient offers.
