Designed specifically for adults with strong jaws who grind or clench their teeth, it features a patented living hinge and open front for natural jaw movement and breathing. By advancing the lower jaw 2mm, it effectively opens airways to reduce snoring immediately, offering a ready-to-use, comfortable, and long-lasting solution for restful sleep. ## Description This pack includes a single, blue Firm Size #1 mouthpiece. Crafted with a stiffer-grade material and an extra-strong hinge, the Firm mouthguard is ideal for individuals who clench or grind their teeth. This mouthpiece is more durable and can withstand grinding without rapid wear. It's a great choice if your Comfort mouthpiece wears out quickly and needs frequent replacement, more than every 3 to 4 months. However, note that the Firm mouthpiece is harder than our Comfort sizes and best suited for those with healthy, strong jaws. Use our premium storage case (sold separately) to protect your Firm mouthpiece and preserve its patented living hinge for enhanced durability. New to ZQuiet? We recommend starting with our 2-Size Comfort Starter Pack, which comes with two differently-sized mouthpieces that are softer than the Firm option. Size #1 is recommended if you have an overbite (lower front teeth sit behind the upper front teeth) or a normal bite with light to moderate snoring. ZQuiet’s living hinge technology with an open front design lets you open and close your mouth naturally and even allows you to talk or take a sip of water. Minor side effects, such as drooling or jaw discomfort, are normal and tend to fade with consistent use. In 2008, our co-founders Dan and Trina developed the ZQuiet mouthpiece to address Dan's snoring issue. Fast forward two decades, our FDA-cleared mouthpiece, along with our range of other anti-snoring products, has helped millions of people overcome snoring and improve their lives. ## Features - Firm & Sturdy: Designed with a stiffer-grade material and an extra-strong hinge for improved durability; If you're new to ZQuiet, we recommend starting with our 2-Size Comfort Starter Pack that includes 2 differently sized, softer mouthpieces - Suitable For: People who clench and grind their teeth and/or prematurely wear out the standard ZQuiet mouthpiece; The Firm mouthguard is only for individuals with very healthy teeth and strong jaws - Effective Snoring Relief: Targets the root cause of snoring by slightly advancing your lower jaw (+2mm) to keep your airways open while you sleep; Provides immediate snoring relief and all-night comfort so you and your partner can enjoy restful sleep - Convenient: Ready to use out of the box - no boiling or molding needed; Dentist-designed, FDA-cleared and approved for OTC use; Made in the USA with BPA and latex-free medical grade material - Designed for Comfort: Patented living hinge technology with an open front design enables you to move your jaw freely, breathe naturally and even take a drink of water ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CTKYBTJ3 | | ASIN | B0CTKYBTJ3 | | Age Range Description | Adult | | Best Sellers Rank | #269,464 in Health & Personal Care ( See Top 100 in Health & Personal Care ) #13,902 in Oral Care | | Brand | Zquiet | | Colour | Blue | | Customer Reviews | 3.6 3.6 out of 5 stars (112) | | Date First Available | 3 May 2024 | | Global Trade Identification Number | 00858522003333 | | Item Dimensions | 12.7 x 9.5 x 3.6 Centimeters | | Item Dimensions LxWxH | 12.7 x 9.5 x 3.6 Centimeters | | Item Weight | 50 g | | Item part number | ZQFRM1 | | Manufacturer | ZQuiet | | Manufacturer | ZQuiet | | Manufacturer Part Number | ZQFRM1 | | Model Name | Firm Size #1 | | Net Quantity | 1.00 Count | | Number of Items | 1 | | Number of Packs | 1 | | Product Dimensions | 12.7 x 9.53 x 3.56 cm; 50 g | | Recommended Uses For Product | Antiseptic | | UPC | 858522003333 | | Unit Count | 1.00 Count | ## Product Details - **Age Range (Description):** Adult - **Brand:** Zquiet - **Colour:** Blue - **Item dimensions L x W x H:** 12.7 x 9.5 x 3.6 Centimeters - **Manufacturer:** ZQuiet - **Model Name:** Firm Size #1 - **Net Quantity:** 1.00 Count - **Number of Items:** 1 - **Recommended Uses For Product:** Antiseptic - **UPC:** 858522003333 ## Images ![ZQuiet, Anti-Snoring Mouthpiece, Firm Size #1, Strong & Durable Mouthguard, Ideal for Those Prone to Teeth Grinding & Clenching, Made in USA, Size 1 - Image 1](https://m.media-amazon.com/images/I/31Ww9DNVsZL.jpg) ![ZQuiet, Anti-Snoring Mouthpiece, Firm Size #1, Strong & Durable Mouthguard, Ideal for Those Prone to Teeth Grinding & Clenching, Made in USA, Size 1 - Image 2](https://m.media-amazon.com/images/I/41Ui8W6V2aL.jpg) ![ZQuiet, Anti-Snoring Mouthpiece, Firm Size #1, Strong & Durable Mouthguard, Ideal for Those Prone to Teeth Grinding & Clenching, Made in USA, Size 1 - Image 3](https://m.media-amazon.com/images/I/41sPYOfXGZL.jpg) ![ZQuiet, Anti-Snoring Mouthpiece, Firm Size #1, Strong & Durable Mouthguard, Ideal for Those Prone to Teeth Grinding & Clenching, Made in USA, Size 1 - Image 4](https://m.media-amazon.com/images/I/41c7qZZUCBL.jpg) ![ZQuiet, Anti-Snoring Mouthpiece, Firm Size #1, Strong & Durable Mouthguard, Ideal for Those Prone to Teeth Grinding & Clenching, Made in USA, Size 1 - Image 5](https://m.media-amazon.com/images/I/41iNCdWi-mL.jpg) ## Frequently Bought Together - ZQuiet, Anti-Snoring Mouthpiece, Firm Size #1, Strong & Durable Mouthguard, Ideal for Those Prone to Teeth Grinding & Clenching, Made in USA, Size 1 - ZQUIET Premium Storage Case for ZQuiet Anti-Snoring Mouthpiece (Device NOT Included) – Durable, Protective, Ventilated, and Convenient for Everyday Storage and Travel - ZQuiet, Clean, Cleaning Solution for All Oral Appliances, Chlorine-Free, Fresh Mint Scent, Travel-Size, TSA-Compliant --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/678605078-zquiet-anti-snoring-mouthpiece-firm-size-1-strong-and-durable](https://www.desertcart.jp/products/678605078-zquiet-anti-snoring-mouthpiece-firm-size-1-strong-and-durable) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-23*
