When it comes to anti-snoring mouthpieces, the SnoreRx Plus stands out as one of the more sophisticated over-the-counter options available. As someone who has spent years navigating sleep challenges and testing various products, I approach these devices with healthy skepticism. Marketing claims are one thing; actual performance is another. In this review, I will break down exactly what the SnoreRx Plus offers, who it works best for, and whether it justifies its price tag.
The SnoreRx Plus is a mandibular advancement device (MAD) designed to reduce or eliminate snoring by repositioning your lower jaw forward during sleep. This mechanism opens the airway, allowing for smoother breathing and quieter nights.
What Is the SnoreRx Plus and How Does It Work?
The SnoreRx Plus is manufactured by Apnea Sciences Corporation, a California-based company producing anti-snoring solutions since 2009. The device works by gently moving your lower jaw forward, preventing the soft tissues at the back of your throat from collapsing and vibrating as air passes through.
According to Mayo Clinic, snoring occurs when air flows past relaxed tissues in the throat, causing them to vibrate. The SnoreRx Plus addresses this by holding the mandible in a forward position, tightening these tissues and creating more space in the upper airway.
What sets the SnoreRx Plus apart from many competitors is its micro-adjustability. The device allows you to advance your jaw in precise 1-millimeter increments, up to 6 millimeters total. This granular control means you can find your optimal setting rather than being forced into a fixed position.
Key Features and Specifications
FDA-Cleared Materials: The device is constructed from medical-grade copolymer plastic, the same material used in high-quality athletic mouthguards. This FDA-cleared material is hypoallergenic, BPA-free, and latex-free.
Thermal Matrix Fitting System: The SnoreRx Plus uses a boil-and-bite customization process. You heat the device in boiling water, then bite down to create a personalized impression of your teeth.
Accu-Adjust System: The patented adjustment mechanism allows for 1-millimeter incremental changes to jaw advancement. Both sides feature tabs with clear measurements up to 6mm.
Vertical Jaw Movement: Unlike the standard SnoreRx, the Plus version adds lateral adjustability, allowing your jaw to move up and down more freely while wearing the device.
V-Flow Design: An opening at the front allows for mouth breathing, essential for anyone who experiences nasal congestion or naturally breathes through their mouth while sleeping.
Effectiveness: What the Research Says
Having spent over a decade managing anxiety-driven insomnia, I have developed a discerning eye for sleep products. My approach is simple: does it actually help, and is the improvement worth the cost? With anti-snoring mouthpieces, the challenge is that snoring often is not your own problem to notice. Tools like SnoreLab can record and analyze snoring sounds, giving objective data. Multiple users report dramatic drops in SnoreLab scores after using the SnoreRx Plus.
A 2021 systematic review in Sleep Medicine Reviews examined mandibular advancement devices for treating snoring and found that MADs improved outcomes across multiple patient populations, consistently delivering positive results in reducing snoring intensity.
Research from the Journal of Pharmacy & Bioallied Sciences notes that MADs are considered a valid first-choice treatment for simple snorers and those with mild OSA. These devices work by producing anatomical variations in the upper airway, increasing the pharyngeal area and stabilizing the jaw.
According to Cleveland Clinic, snoring becomes more common with age as muscle tone decreases. The SnoreRx Plus addresses this by mechanically holding the airway open, compensating for the natural relaxation of throat muscles during sleep.
Setting Up the SnoreRx Plus
The fitting process requires patience but is manageable. Bring a cup of water to a boil, submerge the device for exactly 60 seconds, rinse briefly in cold water, then bite down firmly for 3 minutes to create your personalized mold.
Start at the 1-millimeter advancement setting and wear for two to three nights before adjusting further. Most users find their optimal position between 3 and 5 millimeters. Moving in small increments is important because excessive advancement can cause jaw soreness.
Comfort and Wearability
Comfort is perhaps the most critical factor determining whether someone will stick with an anti-snoring mouthpiece long enough to see results. A device that works perfectly but sits unused in a drawer is worthless. The SnoreRx Plus addresses this through several thoughtful design choices.
From my experience with oral devices, the first few nights always feel strange. You are putting something foreign in your mouth and expecting to sleep peacefully, which is not intuitive. The adjustment period typically lasts one to two weeks, during which mild jaw soreness, excessive salivation, and temporary bite changes are common. These side effects generally diminish as your muscles adapt.
The vertical jaw movement feature allows you to open and close your mouth naturally while wearing the device, which feels significantly less restrictive than rigid mouthpieces. The V-Flow front opening ensures you can breathe through your mouth if needed, eliminating that claustrophobic sensation some people experience with fully enclosed designs.
The Sleep Foundation notes that the SnoreRx Plus is somewhat bulkier than some competitors, which may not suit people with smaller mouths. However, the trade-off is durability, with the device lasting approximately 9 to 15 months.
Potential Side Effects
Initial Jaw Soreness: Most users experience temporomandibular discomfort during the first week or two. This typically resolves as your muscles adapt.
Excessive Salivation: Having a foreign object in your mouth triggers increased saliva production. This usually diminishes over time.
Temporary Bite Changes: Some users notice their teeth do not fit together quite right immediately after removal. Research in the European Journal of Orthodontics found that orthodontic side effects from MAD use are generally small.
Not Suitable for Everyone: The device is not appropriate for people with loose dental work, dentures, or severe TMJ disorders.
Pricing and Value Assessment
The SnoreRx Plus retails at $99.99, with discounts for purchasing two. The standard SnoreRx (without vertical jaw movement) is $59.99. Custom-fitted devices from dentists typically cost $1,500 to $3,000, making the SnoreRx Plus a sensible starting point.
When I evaluate any sleep product, I ask: is this worth the money? At roughly $100 with a 9 to 15 month lifespan, the device costs approximately 37 cents per night. The company offers a 30-night trial period with a full refund (minus shipping) if unsatisfied. If you are exploring options, read about the best anti-snoring devices for 2025 to compare.

Who Should Consider the SnoreRx Plus?
The SnoreRx Plus is best suited for adults with primary snoring who want a customizable solution with precise adjustability, people who prioritize durability and value, and those who mouth-breathe during sleep.
It may not be ideal for people with very small mouths, loose dental work, or complete dentures. It is also not appropriate as primary treatment for diagnosed obstructive sleep apnea.
The Bottom Line
The SnoreRx Plus represents a well-designed entry in the mandibular advancement device category. Its combination of FDA-cleared materials, precise micro-adjustability, and vertical jaw movement addresses many of the common complaints about over-the-counter anti-snoring mouthpieces.
Is it perfect? No. The device requires a learning curve, side effects during the adjustment period are common, and it may be too bulky for some users. But for many snorers, particularly those whose partners have issued ultimatums about the nighttime noise, it offers a legitimate path toward quieter sleep.
My approach to sleep products has always been pragmatic. If something works and the benefits outweigh the drawbacks, it earns a place in the toolkit. The SnoreRx Plus meets that threshold for people dealing with uncomplicated snoring who want a customizable, durable solution without the expense of a custom dental device. For more context, our article on whether anti-snoring devices actually work explores the evidence in depth.
The 30-night trial period means you can test it risk-free. Given the potential for dramatically improved sleep quality for both you and your partner, that trial seems worth taking.

Frequently Asked Questions
How does the SnoreRx Plus differ from the original SnoreRx?
The Plus model includes a smaller, more compact design and improved adjustment mechanism for easier fine-tuning. Both use mandibular advancement technology, but the Plus allows for slightly more precise jaw positioning. The original SnoreRx remains effective for many users, so the choice depends on your preference for fit and adjustability rather than a major functional overhaul. For a full side-by-side, see our SnoreRx vs SnoreRx Plus comparison.
How long does a SnoreRx Plus mouthpiece last before needing replacement?
Most users report the device lasts 1 to 2 years with proper care and nightly use. Durability depends on how aggressively you grind your teeth and how well you maintain the piece. Storing it in the provided case and cleaning it regularly can extend its lifespan. SnoreRx sells replacement mouthpieces separately if yours becomes damaged or worn.
Can I use the SnoreRx Plus if I have obstructive sleep apnea?
The SnoreRx Plus is designed for snoring, not sleep apnea treatment. If you have diagnosed obstructive sleep apnea, a CPAP machine or prescription oral appliance is the standard approach. That said, some people with mild sleep apnea use MAD devices, but you need your doctor’s approval first. Do not substitute a commercial anti-snoring device for proper sleep apnea care.
Is jaw soreness normal when using the SnoreRx Plus?
Minor jaw discomfort during the first week is common as your muscles adjust to the forward positioning. This typically fades within 7 to 10 days. Persistent soreness after two weeks suggests the fit or advancement setting may be too aggressive. Reduce the forward position slightly or consult the company’s support team. If pain continues, a dentist should evaluate whether the device suits your jaw structure.

The SnoreRx Plus costs around 100 dollars and includes a 30-day money-back guarantee if you’re unsatisfied. The company offers a one-year warranty against manufacturing defects. Additional replacement mouthpieces cost roughly 40 dollars each. This pricing sits in the mid-range for mandibular advancement devices, making it moderately accessible for most budget-conscious buyers.
How does SnoreRx Plus compare to other anti-snoring mouthpieces on the market?
