Restful Sleep Starts with Better Breathing
Sleep affects nearly every aspect of your health, from energy level and mood to cardiovascular and cognitive function. Yet millions of people live with untreated sleep apnea or disruptive snoring that keeps them—and their loved ones—from getting the rest they need. At Family Smile Centers in St. Charles County, we offer custom oral appliances that are comfortable, quiet, and effective for many patients. With advanced training and technology, we’ll help you uncover the root of your sleep issues and create a solution that fits your lifestyle.
What Is Obstructive Sleep Apnea?
Obstructive sleep apnea occurs when the soft tissues in the back of the throat relax too much during sleep, partially or completely blocking the airway. This leads to pauses in breathing—often lasting 10 seconds or more—followed by a brief awakening or gasp for air. These interruptions can happen dozens or even hundreds of times each night. Although patients with sleep apnea may not fully awaken during these episodes, the repeated disruptions prevent them from reaching deep, restorative sleep. Over time, untreated apnea can significantly impact physical health, mental clarity, and emotional well-being.

Signs and Symptoms to Watch For
It’s not always easy to know when sleep apnea is the cause of your fatigue or snoring. Many people are unaware that they stop breathing at night, and the symptoms may be mistakenly attributed to stress, age, or lifestyle.
If you or your bed partner has noticed any of the following signs, it’s a good idea to pursue a sleep evaluation:
- Loud or persistent snoring
- Gasping or choking sounds during sleep
- Morning headaches or dry mouth
- Daytime sleepiness, fatigue, or brain fog
- Difficulty concentrating or irritability
- Jaw clenching or teeth grinding at night
- Elevated blood pressure or heart palpitations
Even if you don’t experience all these symptoms, one or two may be enough to justify a closer look, especially if your sleep doesn’t feel refreshing.

The Risks of Untreated Sleep Apnea
Sleep apnea is more than just a nuisance—it’s a serious health condition with wide-ranging effects. When the brain and body don’t receive enough oxygen at night, it stresses the cardiovascular system and can disrupt hormone regulation, metabolism, and immune function.
Long-term consequences of untreated sleep apnea may include:
- High blood pressure
- Increased risk of heart disease or stroke
- Type 2 diabetes
- Depression or anxiety
- Weight gain or difficulty losing weight
- Reduced performance at work or school
- Increased risk of accidents due to drowsiness
Addressing sleep apnea early can help prevent these complications and improve your quality of life almost immediately.


Oral Appliance Therapy: A Comfortable CPAP Alternative
For patients with mild to moderate obstructive sleep apnea—or those who cannot tolerate CPAP—oral appliance therapy offers a safe, effective, and convenient treatment option. This custom-fitted device is worn at night and gently repositions the lower jaw and tongue to keep the airway open. Unlike CPAP machines, which use continuous air pressure through a mask, oral appliances are small, quiet, and portable. Many patients find them significantly more comfortable and easier to integrate into their nightly routine.
Custom oral appliances offer several practical advantages:
- No bulky equipment or air hoses
- Easy to wear, clean, and travel with
- Quiet operation with no motor or fan noise
- Fully customized to fit your bite and airway
- Effective for many cases of OSA and chronic snoring
If you’ve been diagnosed with OSA or suspect a sleep issue, an oral appliance may help you breathe and rest more easily, without disrupting your lifestyle.

Who Is a Candidate for Oral Appliance Therapy?
Oral appliance therapy is best suited for patients with mild to moderate obstructive sleep apnea and those who snore without apnea. It’s also a valuable alternative for patients who have tried CPAP but found it too uncomfortable, noisy, or inconvenient. We collaborate with your sleep physician to determine candidacy and use existing sleep study results to guide treatment. If you haven’t yet completed a study, we can refer you to a trusted partner for diagnostic testing.
