Last updated: September 25th, 2023

The Sleep Well Appliance

Snoring can be a disruptive sleep issue affecting millions worldwide. The Sleep Well Appliance presents an innovative solution to this problem by keeping the airway open and reducing snoring through its comfortable forward position of the jaw and tongue. In this review, we explore the features and benefits of this FDA-cleared device, designed not only for snoring but also to address mild to moderate obstructive sleep apnea (OSA). Its unique design, ease of use, and high patient compliance make it an appealing choice for those seeking peaceful sleep.

Key Features of the Sleep Well Appliance

  • Comfortable Forward Positioning: The Sleep Well Appliance gently holds the jaw and tongue in a comfortable forward position, preventing airway obstruction caused by soft tissue collapse during sleep.
  • FDA-Cleared for Snoring and OSA: This device is FDA-cleared for both snoring and mild to moderate obstructive sleep apnea, making it a versatile solution for various sleep-related issues.
  • AP Advancement: The Sleep Well Appliance allows for up to 9mm of advancement, ensuring an optimal fit and personalized treatment for each user.
  • Patented Protrusive Element (PE) Inserts: These inserts maintain constant protrusiveness, ensuring the effectiveness of the appliance in keeping the airway open.
  • Non-Threatening Design: Its simple design and comfortable fit make the Sleep Well Appliance non-threatening and easy to use for individuals of all ages.
  • Easy-to-Clean and Adjust: Maintaining the Sleep Well Appliance is hassle-free, ensuring a hygienic experience and long-term usability.

Perfect for Bruxing Cases

Aside from its effectiveness in reducing snoring and OSA, the Sleep Well Appliance is particularly ideal for individuals with bruxism (teeth grinding) issues. Its unique design and custom fit can help mitigate the impact of bruxism while addressing snoring simultaneously. This makes it a comprehensive solution for those facing multiple sleep-related challenges.

Construction Bite Requirements

When using the Sleep Well Appliance, it's essential to take note of the construction bite requirements. For proper fitting and effectiveness, an edge-to-edge 4mm vertical opening is required when taking the construction bite. Adhering to this guideline ensures optimal results and comfort during use.

Additionally, soak the appliance in a denture cleaning solution once a week, following the manufacturer's instructions.

Description of the Lamberg Sleep Well Device

The Lamberg Sleep Well Device is a two-part mouthpiece designed to address both snoring and sleep apnea. It comprises two distinct components or plates that engage the teeth of each dental arch separately. The upper and lower dental plates connect in the front area of the mouth using a patented coupling system, which includes a protrusive element on the upper plate and a complimentary mate on the lower plate. By repositioning the lower jaw and tongue forward, the device increases the patient's airway size, promoting improved breathing during sleep. Each device is custom-made for the patient, ensuring a precise fit and is adjustable both upon delivery and anytime thereafter.

Contraindications, Risks, Warnings, and Cautions


The Lamberg Sleep Well Device is contraindicated in the following instances:

  • Central Sleep Apnea (CSA)
  • Severe respiratory disorders
  • Loose teeth or advanced periodontal disease
  • Patients under 18 years of age
  • Edentulous or insufficient number of teeth to retain the device
  • Inadequate mandibular range of motion
  • Myofacial dysfunction
  • Anthropathy of the TMJ
  • Patients undergoing orthodontic treatment or dental work that requires temporary crowns

Important Note: If the appliance is broken, refrain from wearing it and seek professional assistance.


While using the device, patients may experience the following risks:

  • Tooth movement or changes in dental occlusion or bite
  • Gingival irritation or dental soreness
  • Pain or soreness of the TMJ or facial muscles
  • Obstruction of oral breathing
  • Excessive salivation
  • Loosening and/or dislodgment of dental fillings or crowns
  • A small percentage of patients may experience an increase in apneic and hypopneic events while using the oral appliance. In such cases, patients should discontinue the device's use and consult their dentist.

General Warnings and Cautions

The performance of the device may be adversely affected by certain factors, including:

  • Weight gain and obesity
  • Alcohol consumption and sedative use
  • Allergies and smoking
  • Cold or sickness that compromises nasal breathing
  • Very high altitudes
  • Increased age and hormonal changes in women such as menopause

Patients should not modify or share the device. In the case of broken appliances, patients must refrain from wearing them and seek assistance from their dentist.

Use Instructions

What to Expect

When initially using the Lamberg Sleep Well Device, patients may find it cumbersome. During the first few weeks of use, an increase in salivary flow is common, which should gradually subside. Some patients may experience minor gagging or awkwardness swallowing, but these sensations are not permanent. After nighttime use and removal of the device, patients may feel that their teeth do not bite together as before. If this feeling persists for twenty minutes after removal, the SML™ Good Morning Positioner can be used. In case of continued discomfort, patients should discontinue use and consult their dentist.

In the long term, contacts between teeth may become less tight as patients adapt to their intra-oral sleep apnea device. Most patients experience little to no discomfort after a few weeks of use.

Wearing the Appliance

  1. Prior to inserting the appliance, brush and floss your teeth.
  2. Insert the appliance into your mouth when going to sleep. Place the upper dental plate on your upper arch of teeth first, press up with your thumbs to ensure it is fully seated and secure, and does not rock. Then, place the lower dental plate on your lower teeth and press down until it is securely seated.
  3. While the appliance is in your mouth, avoid popping it in and out with your tongue.
  4. For removal, take out the lower dental plate first, followed by the upper dental plate. When removing the upper plate, pull down slowly on the metal loops by your upper molars.
  5. If a tooth feels sore or if you experience muscle/joint soreness, bring the appliance to your dentist for an adjustment.
  6. In the event of a broken appliance, refrain from wearing it and bring it to your dentist for repair.


To maintain hygiene, clean the appliance each morning after use with a denture toothbrush or a regular toothbrush using toothpaste or a denture cleaning paste like Dentu-Creme or Fresh-n-Brite, available in supermarkets. Use cold water only for cleaning. Approximately once a week, soak the appliance in a denture cleaning solution, following the manufacturer's instructions. After cleaning, rinse the appliance under cool water and completely air dry it before storing.

CAUTIONS: DO NOT soak the appliance in mouthwash or alcohol, or bleach, as these may weaken the appliance. DO NOT place it in hot or boiling water or expose it to excessive heat, as this could distort the appliance.


The Sleep Well Appliance offers a promising solution for individuals struggling with snoring, mild to moderate sleep apnea, and bruxism. Its FDA-cleared design, ease of use, and custom fit make it an attractive option for those seeking a non-invasive and comfortable solution to improve their sleep quality.
