Sleep is not optional — it is a foundational part of health. When breathing is repeatedly interrupted at night, the consequences extend beyond feeling tired: concentration, mood, metabolism, and cardiovascular health can all be affected. Nationwide estimates put obstructive sleep apnea (OSA) in the tens of millions of adults, and a substantially larger number of people experience habitual snoring that may signal an underlying airway problem. At Fay Hu General Dentistry, we screen for signs of sleep-disordered breathing and offer dental solutions that work in coordination with medical care to help restore safer, more restorative sleep.
Understanding sleep apnea means recognizing it as a medical condition with dental implications. This page explains how sleep apnea develops, how it is identified, and the role of oral appliance therapy among the treatment options available. Our goal is to give patients clear, practical information so they can make informed decisions with their physician and dental team.
Obstructive sleep apnea occurs when the airway partially or completely collapses during sleep, causing breathing pauses that reduce oxygen levels and fragment sleep. These interruptions trigger brief awakenings and activate stress responses in the body, even if the person does not remember waking. Over time, the repeated strain on the cardiovascular and nervous systems can increase risk for hypertension, heart disease, and stroke.
Beyond heart health, poor sleep from apnea affects metabolic regulation and mood. Many people with untreated OSA develop insulin resistance, experience weight gain, or have worsening control of diabetes. Cognitive symptoms — such as slowed thinking, memory lapses, and difficulty sustaining attention — are common and can interfere with work, driving safety, and daily functioning.
The impact of sleep apnea is not limited to the individual. Partners often report disruptive snoring and episodes that cause shared sleep loss. Recognizing the broader health and quality-of-life effects is an important first step toward timely evaluation and effective treatment.
Some signs of sleep apnea are loud and obvious: chronic, noisy snoring; choking or gasping sounds during sleep; and witnessed pauses in breathing. Other symptoms are less dramatic but equally important, such as daytime sleepiness, persistent morning headaches, difficulty concentrating, or mood changes like increased irritability or low motivation.
People at higher risk often share certain characteristics. Excess neck circumference, being overweight, nasal congestion, a family history of sleep apnea, and anatomical features like a retruded jaw or large tonsils can increase susceptibility. However, sleep apnea also affects people without classic risk factors, including those who are not visibly overweight.
Because many patients are unaware they stop breathing at night, it helps to ask a bed partner or household member about observed symptoms. When uncertainty exists, screening questionnaires and a clinical exam can identify warning signs that warrant further evaluation with a sleep medicine specialist.
Diagnosis begins with a thorough history and physical examination. Dentists play a valuable role in screening by noting signs like tooth wear from bruxism, a narrow upper airway, or jaw alignment issues that may suggest an elevated risk. If screening indicates concern, referral to a sleep physician is the usual next step for definitive testing.
The standard diagnostic test is an attended polysomnography study in a sleep lab, which records breathing, oxygen levels, heart rhythm, and brain activity during sleep. For many patients, an at-home sleep apnea test is an acceptable alternative; these portable studies measure airflow, respiratory effort, and oxygen saturation to determine whether obstructive events occur and how frequent they are.
Results from a sleep study include an apnea-hypopnea index (AHI) that quantifies the severity of disordered breathing. The sleep physician uses these findings, along with symptoms and medical history, to recommend an appropriate treatment plan. Dentists who provide oral appliance therapy typically work closely with referring sleep physicians to ensure a coordinated approach.
Treatment for obstructive sleep apnea is individualized and depends on severity, patient preferences, and medical considerations. Continuous positive airway pressure (CPAP) therapy remains the most widely recommended option for moderate to severe OSA because it reliably splints the airway open during sleep. For patients who cannot tolerate CPAP, other strategies are considered.
Lifestyle measures are an important complement to any formal therapy. Weight management, positional therapy to avoid sleeping on the back, alcohol avoidance before bedtime, and optimizing nasal breathing can all reduce symptoms in appropriate cases. For patients with structural contributors, surgical consultation may be part of a comprehensive plan.
Dental sleep medicine offers a well-established alternative for many with mild to moderate OSA or for those who find CPAP intolerable. Oral appliances are designed to keep the jaw or tongue in a forward position to maintain an open airway. A collaborative, multidisciplinary approach — involving the sleep physician, ENT specialists, and the dental team — ensures that the chosen therapy aligns with the patient’s health profile and treatment goals.
Custom oral appliances are precision devices created to fit an individual’s mouth and airway needs. Unlike over-the-counter solutions, a custom appliance begins with a detailed oral exam and accurate records of the teeth and bite, whether taken with digital scans or traditional impressions. The device is then fabricated to specific specifications that balance airway opening with jaw comfort and oral health.
Initial fitting and adjustment are critical. The appliance may require titration — small incremental changes to jaw positioning — to achieve the optimal balance of comfort and effectiveness. During this period, patients are monitored closely for symptom improvement, side effects like jaw discomfort, and any changes in dental alignment. Regular follow-up visits allow the dental team to recalibrate the device as needed.
Effectiveness is usually assessed in partnership with the sleep physician. Repeat sleep testing or home studies can document objective improvement in breathing events, while patient-reported outcomes track sleep quality, daytime alertness, and snoring reduction. Long-term maintenance includes periodic dental exams to monitor bite changes, tooth movement, and device integrity.
When chosen and managed correctly, custom oral appliances can offer a comfortable, portable, and effective option for many patients. Our practice emphasizes precise fabrication, careful titration, and ongoing coordination with medical providers so that each patient receives safe, evidence-based care tailored to their needs.
In summary, obstructive sleep apnea is a common, treatable condition with implications for overall health and daily functioning. Early recognition, accurate diagnosis, and a coordinated treatment plan that may include oral appliance therapy can significantly improve sleep quality and long-term outcomes.

Sleep apnea is a sleep disorder characterized by repeated pauses in breathing that interrupt normal sleep patterns. These pauses, called apneas and hypopneas, reduce oxygen levels and fragment restorative sleep. The most common form, obstructive sleep apnea, is caused by collapse or blockage of the upper airway during sleep.
Untreated sleep apnea increases the risk of high blood pressure, heart disease, diabetes and daytime impairment. People with sleep apnea often experience loud snoring, choking or gasping episodes and persistent daytime sleepiness. Early recognition and treatment can significantly improve health, safety and quality of life, and evaluation can begin at the office of Fay Hu General Dentistry.
Nighttime signs of obstructive sleep apnea include loud, frequent snoring, witnessed breathing pauses and sudden gasping or choking that wakes a person from sleep. Some patients report restless sleep, repeated awakenings and excessive sweating during the night. Because these events occur while asleep, a bed partner's observations are often the first clue.
Daytime symptoms commonly include excessive sleepiness, poor concentration, memory problems and mood changes such as irritability or depression. Many people with sleep apnea also complain of morning headaches and dry mouth on waking. These daytime consequences can affect work performance, driving safety and overall well-being.
Diagnosis typically begins with a medical evaluation and sleep history to document symptoms and risk factors. A physician or sleep specialist may recommend an in-lab polysomnography or a validated home sleep apnea test to measure breathing events and oxygen levels. These tests determine the severity of apnea and guide treatment decisions.
Dental professionals play a complementary role by screening patients during dental exams and identifying oral features that raise suspicion for sleep-disordered breathing. If screening suggests sleep apnea, the dentist will coordinate with the patient's physician or sleep specialist to obtain diagnostic testing and a treatment plan. This collaborative approach ensures both airway health and dental considerations are addressed.
Treatment depends on severity and patient preference and may include lifestyle modifications, positional therapy, continuous positive airway pressure (CPAP) and surgical options. Weight management, avoiding alcohol near bedtime and improving sleep hygiene can help in mild cases. CPAP remains the most effective treatment for moderate to severe obstructive sleep apnea by delivering pressurized air to keep the airway open.
For patients who are not candidates for CPAP or who cannot tolerate it, oral appliance therapy is a proven alternative for many cases of mild to moderate apnea and for snoring. Other treatments, such as positional therapy or referral for surgical evaluation, may be considered when appropriate. A comprehensive plan is developed in collaboration with the patient's medical team to maximize safety and effectiveness.
Oral appliances work by repositioning the lower jaw and tongue to enlarge the upper airway and reduce its tendency to collapse during sleep. Most devices resemble a mouthguard or orthodontic retainer and hold the jaw in a forward position to improve airflow. By mechanically stabilizing soft tissues, these appliances decrease the frequency and severity of apneas and snoring.
Because airway anatomy and dental structures vary, appliances are custom-made from precise impressions and fitted by a trained dental clinician. After delivery, small adjustments are often required to balance comfort with therapeutic effectiveness. Regular follow-up allows for recalibration, symptom assessment and coordination with medical therapy when needed.
Suitable candidates for oral appliance therapy generally include people with mild to moderate obstructive sleep apnea and those who primarily snore. Patients who are unable to tolerate CPAP, who travel frequently, or who prefer a less obtrusive option are often considered. A thorough medical and dental evaluation helps determine candidacy.
Dental health factors such as sufficient teeth for retention, healthy periodontal status and acceptable jaw joint function influence device selection and success. Patients with severe obesity, significant central sleep apnea or certain craniofacial abnormalities may require a medical specialist evaluation first. The dentist and sleep physician work together to select the safest, most effective therapy.
An initial appointment includes a review of symptoms, medical history, sleep study results if available, and a focused oral examination. The clinician will evaluate airway anatomy, dental condition and temporomandibular joint function to determine the appropriate appliance type. Impressions or digital scans of the teeth are taken to produce a custom device.
At the delivery visit the appliance is checked for fit, comfort and basic function, and the patient receives instructions on care and use. Adjustments are typically made over several appointments to optimize airway opening while maintaining dental comfort. Ongoing follow-up includes monitoring symptoms, repeat sleep testing when indicated and periodic dental checks to assess bite changes or wear.
Most patients adapt to a custom oral appliance within a few nights to a few weeks, and many find it more comfortable than mask-based therapy. Common transient side effects include increased salivation, dry mouth or mild jaw soreness during the adjustment period. These effects are usually manageable and often resolve with small appliance modifications or acclimation.
Long-term use requires dental monitoring because appliances can produce tooth movement, bite changes or increased dental wear in some patients. Regular dental evaluations allow early detection and adjustment to protect oral health and jaw function. When necessary, the dentist coordinates care with specialists to address TMJ symptoms or restorative needs.
CPAP is considered the treatment of choice for moderate and severe obstructive sleep apnea because of its ability to virtually eliminate airway collapse when used correctly. However, CPAP adherence can be a barrier for many patients due to mask discomfort, noise or claustrophobia. In contrast, oral appliances offer a portable, quiet and often easier-to-use option that can be highly effective for mild to moderate cases.
Choosing between CPAP and an oral appliance depends on apnea severity, patient tolerance, comorbid conditions and shared decision-making between the patient and care team. Some patients may benefit from combined approaches or a trial period to determine which therapy provides the best symptom control and adherence. Objective follow-up testing helps confirm treatment effectiveness regardless of the chosen modality.
To begin an evaluation, call our office to schedule a consultation and bring any prior sleep study reports, medical records and a list of current medications. Providing a partner's observations about snoring or witnessed pauses can be helpful during the assessment. During the visit we will discuss symptoms, perform an oral exam and explain the appropriate next steps for testing or treatment.
The practice coordinates closely with sleep physicians to ensure diagnostic testing and medical indications are addressed before starting dental therapy. If an oral appliance is recommended, we will custom fabricate, fit and monitor the device to maximize sleep quality and protect dental health.
