Best mandibular advancement devices for sleep apnea

Top pick: VitalSleep Anti-Snoring Mouthpiece. It's the one I'd start with — a boil-and-bite mandibular advancement device you can re-fit at home, with a screw that lets you nudge the lower jaw forward in small steps over a few nights, which is how these actually start working. Strong user ratings for a device in this class.

Who the others suit:

• ZQuiet — first-timers who want the gentlest, most forgiving fit; it's the most widely used starter device.
• Snoreguard — anyone who wants a dentist-style mandibular device without a lab bill.
• PureSleep — a simple, no-frills fixed-advancement option.
• ApneaRx — people who want more adjustment range and a softer dental-grade material.
• myTAP — a step up in build quality, but it's rated lower by users, so read the reviews first.
• EMA / AIO Breathe — lab-made, dentist-prescribed appliances for diagnosed apnea; the serious route if OTC devices don't hold your jaw forward enough.

Two things worth knowing: these help snoring and mild-to-moderate obstructive sleep apnea, not severe OSA — that needs a sleep study and a dentist or sleep physician. And expect a week or two of jaw soreness while you adapt.
