SnoreRx Plus and Zyppah both hold the lower jaw forward, but Zyppah adds a second mechanism: a small elastic band that keeps the tongue from falling back. This "hybrid" approach is Zyppah's signature, while SnoreRx Plus focuses on doing one thing — precise jaw advancement — extremely well. Here is how they compare in 2026.
Quick Verdict
- Choose SnoreRx Plus for precise, adjustable jaw advancement and a proven single-mechanism design.
- Choose Zyppah if you suspect your tongue is part of the problem and want a combined jaw-and-tongue approach.
SnoreRx Plus: Precise Jaw Advancement
SnoreRx Plus is a custom boil-and-bite MAD with calibrated 1 mm adjustment. It targets the most common cause of snoring — the lower jaw and soft tissue relaxing back during sleep — and lets you fine-tune the advancement precisely.

Zyppah: Jaw Plus Tongue (Hybrid)
Zyppah is a boil-and-bite MAD with an added elastic tongue strap, so it addresses both jaw position and tongue position at once. It is made in the USA and is a good option for people whose snoring is partly tongue-based. It is not micro-adjustable the way SnoreRx Plus is.

Which Should You Choose?
If your snoring is mainly caused by the jaw sliding back, SnoreRx Plus's precise adjustment makes it the safer bet. If you have tried jaw-only devices without full success, Zyppah's added tongue strap may close the gap. Some users find the tongue band takes longer to get used to, so factor comfort into your decision.
Frequently Asked Questions
Does the Zyppah tongue strap actually help?
For people whose snoring is partly tongue-based, the added tongue restraint can help. For purely jaw-based snoring, a precise MAD like SnoreRx Plus is often enough.
Is Zyppah harder to get used to than SnoreRx Plus?
Some users need a longer adjustment period with Zyppah because of the tongue band. SnoreRx Plus has a single, familiar MAD feel.
Can I adjust Zyppah after fitting?
No. Zyppah's advancement is set during the boil-and-bite fitting, whereas SnoreRx Plus can be re-adjusted in 1 mm steps.
