Oral appliance therapy vs. CPAP: the real cost comparison over a full treatment course

Part of the series: The Complete CPAP Guide

A CPAP machine costs more upfront than most oral appliances. Once ongoing supply replacement and appliance adjustment fees enter the picture, the multi-year total tells a different story.

A CPAP machine's sticker price sits meaningfully above a custom oral appliance's typical cost in most cases — machines in our own catalog run from $549 for a basic auto-titrating unit up to $949 for machines with advanced data and comfort features, while a dentist-fitted mandibular advancement device typically runs in a comparable or somewhat lower range depending on the specific device and the dental practice's fees. On sticker price alone, this often reads as a wash or a mild edge to the appliance.

The ongoing cost picture changes that comparison meaningfully. CPAP requires regular consumable replacement — mask cushions, filters, tubing, and the mask itself on a defined schedule — that adds up over a multi-year treatment course, generally in a predictable but nontrivial ongoing amount. An oral appliance has essentially no equivalent ongoing consumable cost; it's a durable device that gets periodically checked and adjusted by the dentist who fitted it, not replaced on a supply schedule.

What complicates a clean cost comparison further: an oral appliance's fitting process itself, including the dental visits for impressions, fitting, and follow-up adjustments to get the jaw advancement calibrated correctly, carries its own professional fees that aren't always fully covered by medical insurance the way DME-covered CPAP equipment often is — appliance therapy sometimes falls into a gap between medical and dental insurance coverage that's worth confirming directly with both, rather than assuming coverage parallels CPAP's typical medical-device coverage pathway.

The honest bottom line: for mild-to-moderate OSA where either treatment is a clinically reasonable option, the total cost comparison over several years is closer than the upfront device price suggests, and insurance coverage specifics for the individual patient's plan — not the sticker price of either option — usually ends up being the deciding factor rather than a clear cost winner on paper.
