Snoring is a common nighttime symptom that affects sleep quality for millions of people and their bed partners. While an occasional bout of snoring can be harmless, persistent loud snoring may signal an underlying breathing disturbance that deserves attention. Our goal on this page is to explain what snoring is, clarify when it should prompt further evaluation, and describe how a dental snoring appliance can be a comfortable, effective option for many adults.
At Smiles Dental at Reston Town Center, we combine clinical experience with modern dental technology to evaluate sleep-related breathing issues and determine whether an oral appliance is a suitable path forward. Below you’ll find clear, practical information about causes, candidacy, mechanism of treatment, and what to expect from a custom-fitted snoring device. This overview is designed to help you make informed questions at your consultation and know the next steps if an oral appliance is recommended.
Snoring happens when airflow through the nose and mouth is partially blocked during sleep, causing relaxed tissues in the throat to vibrate. The soft palate, tonsillar tissue, tongue base, and even nasal structures can narrow the airway when muscle tone decreases during sleep. That vibration produces the familiar sound we call snoring, and the loudness or frequency depends on how much the airway is constricted and where the vibration originates.
Different sleeping positions and stages of sleep affect airway tone and collapsibility. For example, sleeping on the back tends to allow the tongue and soft tissues to fall toward the throat, increasing the chance of vibration. Alcohol, sedatives, and poor sleep habits can further reduce muscle tone and make snoring worse. Understanding these mechanical contributors helps guide non-surgical, conservative strategies such as positional therapy and oral appliances.
It’s important to distinguish simple snoring from sleep-disordered breathing. Simple or primary snoring involves noise without the gas-exchange interruptions seen in obstructive sleep apnea (OSA). In contrast, OSA includes repeated airway collapses that reduce oxygen levels and fragment sleep. A dental evaluation can help identify signs that suggest referral for a sleep study or collaboration with a sleep medicine specialist.
Several anatomical and lifestyle factors influence how easily the airway narrows during sleep. Narrow or blocked nasal passages, a long soft palate, enlarged tonsils, or excess tissue at the back of the throat can all impede airflow. Natural differences in jaw and facial structure—such as a smaller lower jaw or a recessed chin—also raise the likelihood of airway obstruction during sleep.
Lifestyle elements play a role as well. Alcohol use, certain medications that relax muscles, poor sleep hygiene, and weight gain may all increase the frequency and intensity of snoring episodes. While aging is associated with gradual muscle tone loss and can make snoring more likely, people of any adult age can experience problematic snoring depending on their individual anatomy and habits.
Identifying these contributors matters because it guides treatment choices. When nasal congestion or positional sleep is the main issue, simple measures may help. When anatomical or jaw-related factors predominate, an oral appliance that repositions the jaw can be a targeted, non-invasive option to open the airway and reduce vibration.
A snoring appliance—sometimes called an oral appliance or mandibular advancement device—is a custom-made dental appliance worn at night that repositions the lower jaw slightly forward. This forward positioning enlarges the upper airway space behind the tongue and soft palate, reducing the tendency for tissues to collapse and vibrate. Unlike bulky over-the-counter devices, a custom appliance is molded from impressions of your teeth for a precise, comfortable fit.
These devices are removable and typically resemble a slim retainer or sports mouthguard rather than a medical apparatus. Because they work by changing jaw position rather than blocking the nose, they are especially helpful for people whose snoring results from tongue or soft-palate collapse. Many patients find them easier to tolerate than continuous positive airway pressure (CPAP) when CPAP is not necessary or not well tolerated.
Oral appliances are designed to be conservative and reversible: they do not require surgery and are worn only during sleep. A dental professional experienced in sleep-related care will assess dental health, bite relationship, and jaw function before recommending an appliance to ensure it is both safe and likely to be effective for your specific anatomy.
Not every snorer is an ideal candidate for an oral appliance, and candidacy depends on a careful clinical assessment. Adults who snore loudly but do not have significant daytime sleepiness or other symptoms of moderate to severe obstructive sleep apnea may benefit most. People with a healthy dentition and sufficient teeth to hold the device in place typically experience the best fit and retention.
Patients with certain dental issues, untreated periodontal disease, or severe temporomandibular joint (TMJ) disorders may need dental care or alternative approaches before an appliance is considered. Likewise, when there are clear signs of moderate to severe sleep apnea—such as repeated gasping or choking during sleep, daytime cognitive impairment, or cardiovascular concerns—a sleep study and multidisciplinary discussion with a sleep physician are appropriate to determine the safest treatment plan.
During your initial consultation, we evaluate bite alignment, jaw movement, and oral health, and review sleep symptoms. If we suspect a higher risk of sleep apnea, we coordinate referral and testing. When an oral appliance is prescribed, it’s because clinical findings and symptom patterns suggest you are likely to achieve meaningful improvement in snoring and sleep quality with a tailored dental solution.
The process begins with a dental exam and impressions or digital scans of the teeth to create a custom-fit device. Once fabricated, the appliance is tested and adjusted to find the right amount of mandibular advancement—enough to open the airway but not so far as to cause discomfort. Early follow-up visits are common to fine-tune the fit and monitor comfort, jaw function, and symptom response.
Adapting to an oral appliance usually takes a few nights to a few weeks. Common early experiences include mild salivation or transient jaw stiffness, which generally lessen as muscles adapt. With proper care—regular cleaning and periodic dental check-ups—the appliance can remain effective for years, though it may require replacement or adjustment over time as the mouth changes.
Follow-up care is important not only to ensure continued symptom relief but also to check for any dental changes or bite shifts. We monitor your progress and coordinate with sleep medicine providers when necessary. If snoring decreases and sleep quality improves, many people and their bed partners notice a significant positive change in nightly rest and daytime energy.
In summary, a custom snoring appliance offers a conservative, reversible treatment option for many adults whose snoring stems from jaw and airway mechanics. If you’re curious whether an oral appliance could help you or a loved one, contact us for more information and to schedule an evaluation. Our team at Smiles Dental at Reston Town Center can guide you through the assessment and, if appropriate, craft a personalized treatment plan to improve nighttime breathing and sleep comfort.
Snoring occurs when airflow is partially blocked during sleep and relaxed tissues in the throat vibrate, producing sound. Common anatomical contributors include a long soft palate, enlarged tonsils, nasal obstruction, or a retruded lower jaw that reduces airway space. Lifestyle factors such as alcohol use, sedating medications, sleep position, and weight gain can also increase the likelihood and loudness of snoring.
Simple or primary snoring produces noise without the repeated breathing interruptions and oxygen drops that define obstructive sleep apnea (OSA). OSA involves recurrent airway collapses that fragment sleep and may cause daytime sleepiness, cognitive symptoms, and cardiovascular risk. Because the management and medical implications differ, patients with signs of OSA should be evaluated and, when appropriate, undergo testing before proceeding with dental appliance therapy alone.
A snoring appliance, often called a mandibular advancement device, repositions the lower jaw slightly forward while you sleep to enlarge the upper airway behind the tongue and soft palate. By stabilizing the jaw and increasing the space for airflow, the appliance reduces tissue vibration and the breathing turbulence that causes snoring. Custom devices are fabricated from dental impressions or digital scans so they fit closely to the teeth and maintain the therapeutic jaw position throughout the night.
Unlike nasal dilators or throat sprays, oral appliances work by mechanically changing jaw and tongue position rather than attempting to alter nasal airflow alone. Most patients find custom appliances slimmer and easier to tolerate than many over-the-counter options because they are modeled to the individual dentition. Because the approach is reversible and non-surgical, it is often offered as a conservative first-line option for appropriate adult patients.
Ideal candidates are adults who snore loudly but do not exhibit clear symptoms of moderate to severe OSA, such as excessive daytime sleepiness, witnessed apneic events with gasping, or significant cardiovascular concerns. Candidates should have sufficient healthy teeth to retain and stabilize the device and should not have untreated periodontal disease or severe dental mobility. Patients with active TMJ pain or limited jaw movement may require additional evaluation or alternative strategies.
A thorough clinical assessment helps determine candidacy; when there is any suspicion of sleep apnea we coordinate referral for sleep testing or collaborate with a sleep medicine specialist. For those with mild OSA or positional breathing problems, an oral appliance can be an effective, well-tolerated option. Treatment selection always balances airway effectiveness with dental and jaw health to ensure safe use over time.
The clinical visit begins with a focused medical and sleep history, including questions about snoring patterns, daytime symptoms, and partner observations. The dentist examines the oral cavity, checks bite alignment, evaluates jaw range of motion and TMJ function, and inspects teeth and gums to confirm the mouth can support an appliance. When indicated, we review sleep questionnaires and may recommend a home sleep test or referral to a sleep physician to rule out or quantify obstructive sleep apnea.
At the office of Smiles Dental at Reston Town Center we discuss the benefits and limitations of oral appliances relative to other therapies and outline what to expect during treatment. If an appliance is appropriate, impressions or digital scans are taken and treatment timelines are reviewed so patients understand follow-up needs. Clear communication about potential side effects and monitoring requirements ensures patients can make informed decisions about proceeding with therapy.
After impressions or digital scans are obtained, the appliance is fabricated to match the patient’s teeth and bite, producing a secure and comfortable fit. On delivery, the device is placed and adjusted to a starting position that advances the lower jaw enough to open the airway while limiting discomfort. Initial adjustments are conservative, and we typically schedule one or more follow-up visits to fine-tune the amount of advancement based on symptom response and comfort.
Incremental adjustments are common because gradual titration helps balance airway improvement with jaw and tooth comfort. During follow-ups we assess jaw mobility, occlusion, and any areas of pressure or irritation, making small changes as needed. Long-term retention may require occasional refinements or remakes to maintain fit as the mouth changes over time.
Many patients experience an adaptation period lasting days to a few weeks, during which they may notice increased salivation, mild jaw stiffness, or transient tooth sensitivity. These effects are usually temporary as muscles and the oral tissues adjust to the new position, and they commonly resolve with nightly use. Sleep partners often report reduced noise levels early on, though measurable sleep improvements may take time to assess formally.
Patients should follow cleaning instructions and wear the device each night as directed to allow the body to adapt and to maximize benefit. If persistent pain, worsening TMJ symptoms, or noticeable bite changes occur, they should contact the dental team promptly for re-evaluation. Routine monitoring helps detect and address issues before they become long-term problems.
Side effects are generally mild and may include temporary jaw discomfort, increased salivation, dry mouth, or minor tooth movement over time. In a smaller number of patients, prolonged use can lead to changes in bite or occlusion; regular dental follow-up helps identify early signs of tooth shifting. Patients with untreated gum disease or very mobile teeth are at higher risk of complications and may need dental treatment before appliance therapy.
Serious complications are uncommon when appliances are prescribed and monitored appropriately, but any new or worsening jaw pain, persistent tooth pain, or significant bite change warrants prompt evaluation. Collaboration with sleep physicians and adherence to recommended follow-up schedules help maintain safety and effectiveness. The goal is to achieve symptom relief while preserving dental and jaw health through careful monitoring.
Effectiveness is monitored both subjectively and objectively: patients and partners report changes in snoring and daytime symptoms, and clinicians assess jaw comfort and dental status at follow-up visits. For patients with known or suspected sleep apnea, repeat sleep testing or home sleep monitoring may be recommended to confirm that the appliance provides adequate respiratory protection. Early follow-ups are common in the first few weeks to adjust fit, with periodic reviews thereafter to check for wear and dental changes.
Long-term maintenance typically involves annual or semiannual dental exams in addition to device checks to ensure ongoing efficacy and oral health. If symptoms recur or the appliance shows significant wear, replacement or refitting may be necessary. Open communication between the dental team, the patient, and any sleep medicine providers ensures coordinated care and timely changes to the treatment plan when indicated.
Yes. Snoring appliances are often part of a broader, multimodal approach that can include positional therapy, nasal treatments for congestion, weight management, and behavioral changes to improve sleep hygiene. For patients with mild to moderate OSA who cannot tolerate CPAP, an oral appliance may be an alternative or adjunct depending on clinical findings and sleep study results. The choice to combine therapies is individualized and based on the severity of breathing disturbances and patient preferences.
When moderate to severe OSA is present, dental appliance therapy may be used together with, or as a complement to, other medical treatments under the guidance of a sleep medicine specialist. Coordination among providers helps ensure that airway safety, cardiovascular risk, and daytime functioning are all addressed. Integrating conservative dental options with medical therapies often produces the most durable and patient-centered outcomes.
