How it is made, and why that matters
ProSomnus trays are milled from a solid block of medical-grade polymer rather than layered up from thermoformed sheets. The practical result is a thinner, more rigid appliance that holds the position it was prescribed at, instead of flexing under a night of clenching.
Thin matters more than it sounds. The device sits between your teeth, and every millimeter of bulk on the tongue side is room your tongue no longer has. A slimmer tray is easier to sleep in, and people who can sleep in an appliance are the people who actually benefit from one.
Yours is built from a digital scan or impressions of your own teeth plus a bite record taken at a specific starting position. It fits one mouth and no other.
What patients notice first
- It is compact and low profile, with far less bulk than most people picture when they hear the word mouthpiece
- The milled surface is smooth, with no seams or rough edges against the tongue and cheeks
- Some designs use interlocking wings and no hardware at all; others use small side components when more movement is needed. Which one suits you depends on your case
- You can open your mouth, swallow, and sip water with it in, which matters if you wake up in the night
- It comes out in the morning and rinses clean in seconds
- No hose, no mask, no power supply, and nothing that beeps. It fits in a case in a carry-on
Advancement happens in small, deliberate steps
Your jaw is not pushed to its final position on day one. We start conservatively and move forward in small increments across follow-up visits, watching two things at once: whether snoring and symptoms are improving, and whether your jaw joints, muscles, and bite are staying comfortable.
Rushing this is the single most common reason people give up on oral appliance therapy. Too much advancement too fast produces jaw soreness, the device ends up in a drawer, and the patient concludes appliances do not work. Going slowly costs a couple of extra visits and is worth every one of them.
Depending on the design, adjustment is made with a small component change or by moving to the next tray in a planned sequence. We tell you which applies to your device at the fitting.
Caring for it
- Rinse it and brush it gently with a soft brush and cool water each morning. Hot water can distort the fit
- Skip regular toothpaste, which is abrasive enough to dull the milled surface over time, and skip bleach entirely
- Let it air dry before it goes back in its case, and keep the case somewhere pets cannot reach it
- Bring it to every checkup so we can inspect the fit, the wear, and your bite
- Do the short morning bite exercises we show you. They take under a minute and help the jaw settle back
What it will not do
It does not cure obstructive sleep apnea, and it only does anything on the nights you wear it. It is also not a substitute for a diagnosis: if you have never had a sleep study and your history points toward apnea, you need a physician's evaluation first, and we will help arrange that referral.
For severe obstructive sleep apnea, CPAP is the standard of care. An oral appliance is generally considered for mild to moderate disease, or for patients who have genuinely not been able to tolerate CPAP, and that decision belongs to you and the physician managing your diagnosis, with our input on whether your mouth can support an appliance at all.
Common questions
How long does it take to get used to wearing it?
Most people need a short adjustment period. Extra saliva for the first few nights and mild jaw soreness in the morning are both common and usually ease as you adapt. If soreness is sharp, lasts well into the day, or gets worse rather than better, call us. That is a signal to back the advancement off, not to push through.
Will it move my teeth or change my bite?
Small bite changes over time are a recognized effect of all mandibular advancement devices, ProSomnus included. It is a trade-off, not a surprise. We record your bite before treatment, recheck it at every follow-up, and teach you morning exercises that reduce the effect. Catching drift early is the reason those follow-ups exist.
Can I wear one if I have crowns, implants, or a partial denture?
Often yes, but it depends on how many healthy teeth remain and where they are, since the appliance has to grip something stable. Existing crowns and implants are usually not a barrier. Full upper and lower dentures generally cannot support a mandibular advancement device. We assess this at the exam before anything is ordered.
How is ProSomnus different from the Silent Nite appliance?
ProSomnus is milled from a solid material, so it is rigid, thin, and holds a prescribed position precisely, which tends to suit heavy grinders and cases needing exact control. Silent Nite is a flexible dual-laminate device adjusted by swapping side connectors, lighter in feel and typically the more economical option. Both are custom made here from your own scan.
Do I still need my sleep study if I only snore?
If a physician has evaluated you and ruled out apnea, treating simple snoring with an appliance is a straightforward conversation. If you have never been evaluated and your history includes witnessed pauses in breathing, choking or gasping at night, or heavy daytime sleepiness, then yes, a sleep study comes first. A dentist cannot diagnose sleep apnea.
How long will the device last?
It depends heavily on how hard you clench, how well it is cleaned, and how your teeth and dental work change over time. Milled devices generally hold up well to grinding, which is one reason we recommend them for heavy clenchers. Bring it to your checkups and we will tell you honestly when it is nearing the end of its useful life.
