Oral sleep appliances are a popular alternative treatment for obstructive sleep apnea (OSA), a sleep-related breathing disorder that affects approximately 12% of the US adult population. OSA occurs when the upper airway is partially or completely blocked during sleep, causing reduced airflow, disrupted sleep, and potentially fatal health complications. Oral appliances work by repositioning the jaw or tongue to open the airway and improve breathing, and they can be especially helpful for those who cannot tolerate or use a Continuous Positive Airway Pressure (CPAP) machine, the gold standard for OSA treatment. While oral appliances are not effective for everyone, they can be a successful treatment option for many individuals with OSA, improving symptoms and reducing snoring.

Oral appliances can help treat sleep apnea by improving airflow
Oral appliances are an effective treatment for sleep apnea, a condition that affects millions of Americans and can lead to serious health complications if left untreated. Obstructive sleep apnea (OSA) occurs when the upper airway is partially or completely blocked during sleep, reducing airflow and causing the brain to wake up enough to resume breathing. This cycle of restricted airflow and interrupted sleep can leave people feeling tired and pose risks for other health issues.
Oral appliances work by pulling the jaw or tongue forward, opening the airway and improving airflow. Mandibular advancement devices (MADs), for example, are made of moulded hard plastic that snaps over the lower and upper teeth, with metal hinges and screws that can be adjusted to push the lower jaw forward. While CPAP (continuous positive airway pressure) therapy is considered the most effective treatment for improving airflow, oral appliances offer a viable alternative for those who find CPAP challenging to use consistently. Oral appliances are also portable and convenient for travel.
The effectiveness of oral appliances in treating sleep apnea depends on several factors. Oral appliances are generally recommended for mild to moderate sleep apnea, and research shows that MAD therapy can significantly reduce symptoms in about 70% of people with OSA. However, one in three people may not see much improvement with MADs, and those with very mild OSA may not notice any difference. People with mild to moderate OSA, younger individuals, females, and those with a lower BMI are more likely to benefit from oral appliance therapy. Additionally, custom-made oral appliances fabricated in a dental lab tend to be more effective and comfortable than pre-made, over-the-counter options.
It is important to consult a healthcare provider before using an oral appliance to ensure it is an appropriate treatment option. A dentist or sleep physician can determine if oral appliance therapy is suitable and collaborate with the patient's doctor to provide the best care. In some cases, oral appliances may be used in conjunction with CPAP therapy or mouth exercises to improve airflow and treat sleep apnea effectively.

Mandibular advancement devices (MADs) are a type of oral appliance that repositions the jaw
Mandibular advancement devices (MADs) are a type of oral appliance that can help treat sleep apnea by repositioning the jaw. They are made of moulded hard plastic and fit over the lower and upper teeth, with metal hinges and screws that push the lower jaw forward, opening the airway. While CPAP (continuous positive airway pressure) is considered the most effective treatment for improving airflow, many people find it challenging to use consistently. Oral appliance therapy is a good alternative for those who struggle with CPAP machines, and some people use both treatments together.
MADs are available either by prescription from a dentist or as over-the-counter "boil and bite" devices. Custom-made MADs are created by taking a scan or impression of the patient's mouth, which is then sent to a dental lab for fabrication. The patient then returns to the dentist for adjustments. Custom devices tend to be more comfortable and effective than over-the-counter options, which often do not fit properly and can lead to a false sense of security.
While MADs can be effective, they are not suitable for everyone. They are not recommended for those with certain dental conditions, such as a lack of teeth to hold the device in place, jaw joint issues, periodontal disease, or those wearing teeth realignment devices. Oral appliances may also not be sufficient for those with low blood oxygen levels due to OSA. Additionally, one in three people do not see much improvement from using a MAD, so it is important to consult a doctor before starting this treatment.
Research has shown that MAD therapy can reduce the number of paused breathing events during sleep and increase blood oxygen levels. It is more likely to be effective for those with mild to moderate OSA, younger individuals, women, and those with a lower BMI. For some, mouth exercises may be recommended in conjunction with MAD therapy to help reposition the tongue and promote nasal breathing.

Tongue-retaining devices are another type of oral appliance that holds the tongue in place
Oral sleep appliances are devices used to treat sleep apnea and snoring by holding the tongue or jaw forward to prevent the tongue from collapsing into the airway. While continuous positive airway pressure (CPAP) machines are considered the most effective treatment for sleep apnea, oral appliances are an alternative option for those who find CPAP machines challenging to use.
Tongue-retaining devices (TRDs) are a type of oral sleep appliance that holds the tongue in place to prevent it from obstructing the airway. These devices consist of a soft plastic splint placed around the tongue to hold it forward during sleep. They are designed to create a slight negative pressure in the lingual compartment, allowing the tongue to be retained in an advanced position. This increases the three-dimensional airway space, which is an effective way of keeping the airway open.
TRDs are customised to each patient and can be used regardless of the condition of their teeth. They are the only oral appliance suitable for patients with edentulism. However, patients must have at least six teeth on both the superior and inferior dental arches for a good fit. Before use, TRDs should be rinsed with warm water to ease placement and flexibility.
The effectiveness of TRDs has been evaluated through clinical studies and patient questionnaires. Clinical studies have shown that TRDs can substantially reduce the number and duration of apnea episodes during sleep in patients with obstructive sleep apnea. A study of 84 apneic patients found that 71% showed a complete or partial response to TRD use, with a significant decrease in the apnea-hypopnea index and snoring intensity. However, TRDs are less effective for patients with severe sleep apnea and those with nasal obstructions.
While TRDs can be a viable option for some patients, they can also cause side effects such as dry mouth and discomfort. It is important to consult with a healthcare provider to determine if TRD treatment is suitable for your specific needs.

Oral appliances are not suitable for everyone and may be uncomfortable
Oral appliances are not a suitable treatment option for everyone with sleep apnea. While they can be effective in improving symptoms for some people, they are not a guaranteed solution. For example, oral appliances may not be suitable for those with certain dental conditions, such as those who do not have enough teeth to hold the device in place, have jaw joint issues, or have significant periodontal disease or gum infections. Additionally, those with severe OSA and low blood oxygen levels may not experience significant improvement with oral appliances alone.
Oral appliances can also be uncomfortable to wear. They clamp onto the upper and lower teeth, similar to a retainer, and some people may find this restrictive or uncomfortable. Tongue-retaining devices, which hold the tongue forward and out of the mouth, can cause dryness and be quite uncomfortable. Even custom-fitted oral appliances may not be comfortable for everyone, and they can be challenging to adjust to.
The effectiveness of oral appliances also depends on the shape of the user's mouth and the severity of their OSA. While oral appliances can be effective for those with mild to moderate OSA, they may not be as successful for those with more severe cases. Additionally, it can be challenging to predict who will benefit most from oral appliance therapy. While research has identified factors such as age, gender, and BMI as potential indicators, the response to treatment can vary significantly from person to person.
Furthermore, oral appliances may not be suitable for children with breathing issues. It is essential to consult a healthcare provider before considering oral appliance therapy for a child. Overall, while oral appliances can be a viable treatment option for some individuals with sleep apnea, they are not a one-size-fits-all solution and may be uncomfortable or ineffective for certain individuals. It is crucial to consult a healthcare professional to determine the most appropriate treatment plan for your specific needs.

Oral appliance therapy is a popular alternative to CPAP machines
Oral appliance therapy is a popular alternative treatment for obstructive sleep apnea (OSA), especially for those who have trouble using a CPAP machine. While CPAP is the best treatment for improving airflow, many find it challenging to use consistently. Oral appliances are dental devices or mouthpieces that you wear in your mouth to keep your airway open while you sleep. They work by pulling your jaw or tongue forward, which opens up your airway and can help you get a better night's rest.
Oral appliances are not as effective as CPAP machines, but they can improve symptoms for some people with mild to moderate OSA. For about 70% of people with OSA, oral appliance therapy can reduce the severity of their condition by more than half, and for a third of people, it can completely resolve their OSA symptoms. Oral appliances can also help to reduce or eliminate snoring, which is a common symptom of OSA.
There are different types of oral appliances available, such as mandibular advancement devices (MADs) and tongue-retaining devices. MADs are made of molded hard plastic and snap over your lower and upper teeth, with metal hinges and screws that can be tightened to push your lower jaw forward. Tongue-retaining devices consist of a soft plastic splint placed around the tongue to hold it forward and out of the mouth throughout the night. These devices can make your mouth very dry and may be uncomfortable.
It's important to note that oral appliances are not effective for everyone. Before considering oral appliance therapy, it's recommended to speak with your doctor or dentist to see if you are a good candidate for this treatment. Certain dental conditions or pending dental work may make oral appliances unsuitable, and they are not effective for central sleep apnea (CSA), which is caused by signalling problems in the brain rather than a blocked airway.
