Oral appliance therapy can be a life-changing solution for patients with sleep apnea or chronic snoring. These custom-made devices gently reposition the lower jaw to keep the airway open during sleep. While they are comfortable for most patients and highly effective, some people experience side effects. The good news is that these side effects can often be prevented or resolved quickly with the proper care and regular follow-ups.

At the Center for TMJ & Sleep Apnea in Lee’s Summit, we combine advanced diagnostics, personalized appliance design, and proactive monitoring to protect your bite, jaw health, and overall comfort.

Understanding Oral Appliance Therapy

Before addressing side effects, it’s important to understand what oral appliance therapy is and how it works. An oral appliance, sometimes called a mandibular advancement device, fits over your teeth like a retainer. It gently moves the lower jaw forward during sleep, reducing airway collapse and improving airflow.

This approach is an effective alternative to CPAP for many patients with mild to moderate sleep apnea and those seeking snoring treatment. Because it’s small, portable, and easy to wear, it can be a more convenient option for daily use and travel.

Common Short-Term Side Effects

Most people adjust to their new oral appliance within the first few weeks. During this adjustment period, it’s normal to notice mild changes in how your mouth feels.

Increased Salivation or Dry Mouth

Some patients notice they produce more saliva at night when first using their appliance, while others may experience dryness. These changes happen because your mouth is adapting to having the appliance in place.

  • If you experience extra saliva, try sleeping on your side to help manage it.
  • For dryness, sip water before bed and avoid alcohol or caffeine late in the day.

Mild Jaw or Tooth Soreness

Temporary soreness is a common sign that your jaw muscles adjust to the new position. This discomfort typically improves as your body adapts.

  • Apply a warm compress to your jaw before bed or in the morning.
  • Use gentle jaw stretches to relax the muscles and promote comfort.

Potential Long-Term Side Effects

While less common, certain side effects can occur with extended use if your appliance is not monitored and adjusted as needed.

Bite Changes

An oral appliance can gradually shift the position of your teeth or alter your bite if not managed correctly. These changes may start subtly, such as noticing your back teeth touch differently in the morning.

Regular monitoring helps detect these shifts early, so your appliance can be adjusted to protect your natural bite.

TMJ Discomfort or Flares

Patients with a history of jaw joint issues may find that the new jaw position triggers TMJ discomfort. This is why it is so important to work with a provider experienced in TMJ treatment and sleep apnea therapy.

Signs of a TMJ flare include:

  • Clicking or popping in the jaw joint
  • Stiffness or locking
  • Pain around the jaw, ear, or temple

How Our Team Prevents and Manages Side Effects

We take a proactive approach to oral appliance therapy by focusing on early detection and precise adjustments.

Advanced Diagnostic Technology

From your first visit, we use advanced diagnostic technology to measure your airway, jaw movement, and bite forces. Tools such as the Pharyngometer, Rhinometer, K7 evaluation, and T-Scan bite analysis give us precise data to optimize your appliance settings.

These measurements help us set the ideal jaw position for effective treatment while minimizing stress on your teeth and joints.

Morning Repositioning Devices

We provide a morning repositioning device to keep your bite in its natural position. This small tool is worn briefly after you remove your oral appliance and helps guide your teeth back into place.

We’ll also show you simple home exercises to relax your jaw muscles and maintain bite stability.

Regular Follow-Ups

Consistent check-ins allow us to:

  • Assess how well your appliance is controlling symptoms
  • Check for any bite or jaw changes
  • Make fine-tune adjustments for comfort and effectiveness

Skipping these visits increases the risk of undetected side effects, so we recommend keeping all scheduled follow-ups.

Self-Care Tips for a Comfortable Experience

You play a big role in making your oral appliance therapy comfortable and successful. Simple habits can make a big difference:

  • Use your morning repositioning device every day
  • Perform any exercises recommended by your provider
  • Keep your appliance clean according to instructions
  • Store it safely when not in use
  • Contact us promptly if you notice changes in your bite or jaw comfort

When to Call Our Office
