Dental sleep medicine is a highly multidisciplinary field that requires specialist knowledge from a range of medical fields. It focuses on treating sleep-related breathing disorders such as sleep apnea and snoring through the use of oral appliance therapy (OAT). Dentists trained in dental sleep medicine can help patients improve their sleep, health, and quality of life by providing custom-fitted oral appliances that keep the patient's airway open during sleep. This treatment is particularly beneficial for those who cannot tolerate continuous positive airway pressure (CPAP) therapy, as it provides a less bulky and loud alternative. While CPAP is considered the most effective treatment for improving airflow, oral appliance therapy offers a more comfortable and convenient option for many patients, improving symptoms such as daytime sleepiness and concentration issues.

What You'll Learn
Oral appliance therapy (OAT)
OAT is a recognised alternative treatment to the "gold standard" of nasally applied continuous positive airway pressure (CPAP) therapy. While CPAP is considered the most effective method for improving airflow, many individuals find it challenging to use consistently due to its bulkiness and noise. In contrast, OAT is a more compact, portable, and quieter solution that can be easily integrated into one's lifestyle.
OAT is customised and fitted by a dentist trained in dental sleep medicine. The process typically involves an initial sleep study or consultation to diagnose the sleep disorder, followed by the design and fitting of the oral appliance. The dentist ensures optimal design, comfort, and therapeutic effectiveness, providing ongoing treatment to make necessary adjustments.
OAT has been shown to improve symptoms of OSA, including daytime sleepiness and concentration issues. It can lead to deeper sleep with fewer disruptions and improved overall health. However, it is important to note that OAT may not work for everyone, and some individuals may require alternative treatments. Additionally, OAT should be used in conjunction with other OSA therapies for optimal results.
Side effects of OAT may include increased salivation, pain in the jaw, teeth, and temporomandibular joint (TMJ), and gum irritation during the initial adjustment period. Long-term side effects are uncommon with proper appliance fitting, but issues such as changes in bite, tooth movement, and jaw muscle changes can occur. Regular dental check-ups are recommended to monitor these potential side effects and make necessary corrections.

Sleep-disordered breathing (SDB)
The diagnosis and treatment of SDB fall under medicine, but as the condition often involves oral and maxillofacial causes and consequences, it is also relevant to dentistry. Dentists can play a role in the assessment and management of SDB, particularly in countries where individuals regularly visit the dentist. They can identify risk factors and consequences, such as snoring, which affects around half of middle-aged men and a quarter of middle-aged women.
Dental sleep medicine is a discipline that focuses on treating sleep-related breathing disorders like SDB and OSA through customised oral appliances. Oral appliance therapy (OAT) is an alternative to continuous positive airway pressure (CPAP) therapy or surgery. OAT involves a small, custom-fitted oral device that protrudes the lower jaw, preventing the tongue from obstructing the airway during inhalation. It is important to note that treating OSA effectively requires a multidisciplinary approach involving collaboration between dentists, doctors, and other specialists.
The treatment for SDB depends on its severity. People with mild apnea have more options, while those with moderate to severe apnea should typically be treated with nasal CPAP. CPAP treatment is indicated for patients with an RDI (respiratory disturbance index) of 30 or more events per hour or those with cardiovascular diseases, including hypertension, ischemic heart disease, or stroke. Conservative non-surgical treatments for SDB include general and behavioural measures such as weight loss, avoiding alcohol before bedtime, and sleeping on one's side. As obesity is a significant predictive factor for OSA, a 10% weight reduction can lead to a 26% reduction in the RDI.

Obstructive sleep apnea (OSA)
The most effective treatment for OSA is positive airway pressure (PAP) therapy, which involves using a small machine that blows air through a mask to prevent airway collapse. However, some people find PAP challenging to use and prefer alternative treatments.
Dental or oral appliances are an option for those with mild to moderate OSA or those with severe OSA who cannot tolerate PAP. These devices are similar to orthodontic retainers and are fitted over the teeth to support the jaw in a forward position, keeping the airway open during sleep. Mandibular advancement devices (MADs) are the most common type of oral appliance, and they work by pulling the lower jaw and tongue forward, creating more space for airflow. MADs are made of hard plastic and feature metal hinges and screws that can be adjusted to push the lower jaw forward.
Oral appliance therapy is an effective, non-invasive treatment that can improve sleep, reduce snoring, and revitalise health. It is important to consult with a qualified dentist or orthodontist to ensure a proper fit and ongoing treatment for oral appliances. Most insurance plans at least partially cover these devices when used for OSA.
Other treatments for OSA include rapid maxillary expansion (RME), which is often used for children, and the newly approved tongue muscle stimulation device, which uses electrical signals to treat snoring and mild sleep apnea.

Dentists' role in sleep medicine
Dental sleep medicine is a highly multidisciplinary field that requires specialist knowledge in areas such as ear, nose and throat specialization, neurology, pulmonary diseases, internal medicine, and psychiatry. Oral and maxillofacial (OMF) surgeons, orthodontists, oral medicine and pathology specialists, and dentists specializing in dental sleep medicine are among those who work in this challenging area.
Dental sleep medicine focuses on treating sleep-related breathing disorders, such as sleep apnea and snoring, through customized oral appliances. Dentists trained in sleep dentistry can offer oral appliance therapy (OAT) as an alternative to continuous positive airway pressure (CPAP) therapy or surgery. OAT devices are small, custom-fitted mouthpieces that protrude the lower jaw, preventing the tongue from falling back and keeping the airway open during inhalation.
Dentists play a crucial role in evaluating patients with obstructive sleep apnea (OSA) for OAT suitability, selecting the appropriate appliance, making adjustments, and monitoring for adverse effects. While dentists are not qualified to independently diagnose OSA, they work collaboratively with sleep medicine physicians to provide the best treatment options for patients. Dentists can also identify risk factors and symptoms of OSA, such as loud snoring, excessive daytime sleepiness, and headaches upon waking.
In addition to OSA and snoring, dentists specializing in sleep medicine can identify and manage other sleep disorders that intersect with dentistry, including sleep-related orofacial pain, xerostomia, hypersalivation, gastroesophageal reflux disease (GERD), and bruxism. They may refer patients with complex orofacial pain to an endodontist, OMF surgeon, or other specialists to ensure comprehensive care.
