The part nobody explains at diagnosis
CPAP is the standard. It was never the only option.
Most people are told about one treatment path. If it doesn't work for your face, your sleep position, or your life, the conversation usually stops there — as if the search for good sleep were over too.
"I tried everything from nasal strips to a full CPAP setup, and none of it stuck. The mask left marks, I couldn't sleep on my side, and I dreaded travel because of the machine."
— a common thread across CPAP-user communitiesWhy it doesn't stick for so many people
-
01
The mask, not the machine Facial contact, straps, and the feeling of something sealed over your nose or mouth is the single most cited reason people stop.
-
02
It travels badly A machine, a hose, and a power source don't fit in a carry-on the way a mouthpiece fits in your pocket.
-
03
It needs continuous power No outlet, no CPAP — a real problem for anyone who sleeps somewhere that isn't a bedroom with a wall socket.
-
04
It changes how you sleep Side-sleepers in particular report the hose and mask make their preferred position uncomfortable or impossible.
How it actually works
It doesn't force air in. It moves the obstruction out of the way.
CPAP treats the airway from the outside — pushing air past whatever is blocking it. A mandibular device works from the inside: gently guiding your lower jaw forward so the tongue and soft tissue stop collapsing into the airway in the first place. Clinical literature recognizes it as a legitimate first-line option for mild to moderate cases, and the standard next step when CPAP isn't tolerated.
| What matters | Typical CPAP | Restwell |
|---|---|---|
| Setup each night | Mask, hose, machine | Slides in, done |
| Power source | Required, always | None needed |
| Sleeping on your side | Often disrupted | Unaffected |
| Travel | Bulky, needs adapter | Fits in a pocket |
| Noise | Motor hum | Silent |

Common questions
Is this a replacement for CPAP if I have severe sleep apnea?
Mandibular devices are most established for mild to moderate cases. If you have severe obstructive sleep apnea, talk with your doctor before switching — this may be used alongside other care, not always instead of it.
How is this different from the mouthpieces I've seen at the pharmacy?
Most off-the-shelf options are one-size boil-and-bite. Restwell adjusts in small increments so you can fine-tune the fit over time, the same way a dentist-fitted device would — without the appointment or the cost.
What if it doesn't work for me?
You have 30 nights to try it. If it's not a fit, contact us for a full refund — no return shipping runaround, no partial-refund tiers.
Do I need a prescription?
No prescription is required to purchase. If you have a diagnosed sleep condition, we still recommend keeping your doctor informed about any change in treatment.
