Tips for Maintaining Oral Health with Sleep Apnea: Managing Dry Mouth and Other Dental Effects

© by

Sleep apnea is a sleep disorder characterized by interruptions to breathing while asleep, sometimes hundreds or even thousands of times every night. Sleep apnea disrupts restful slumber, leading to daytime fatigue and mood disorders. 

Sleep Apnea can have serious repercussions on your oral and overall health. One of the major challenges associated with having sleep apnea is dry mouth (xerostomia), as well as other adverse dental issues like tooth decay, gum disease, and bad breath.

Addressing these oral health concerns is essential to overall wellbeing. This article offers useful strategies on how to best manage dry mouth symptoms while managing sleep apnea effects.

Understanding the correlation between sleep apnea and oral health, adopting effective sleep apnea treatment strategies and employing multidisciplinary approaches, including visiting dentists and sleep specialists, are effective steps that people living with sleep apnea can take to preserve their oral well-being and enhance quality of life. 

Dry Mouth (Xerostomia) and Its Effects on Oral Health 

Dry mouth, otherwise known as xerostomia, occurs when saliva production drops significantly below usual, leaving mouth tissue vulnerable to decay, gum disease, and bad breath. There are several causes of xerostomia, including: 


Numerous antihistamines, antidepressants, and decongestants may lead to dry mouth as a side effect of their use. Radiation therapy can also damage salivary glands leading to dry mouth.

Sjogren’s Syndrome

Sjogren’s syndrome is an autoimmune condition that leads to inflammation of the salivary glands, leading to dry mouth. 

Dry Air

Airplane travel or harsh winter climates may also result in dry mouth symptoms.

Dry mouth can have numerous detrimental effects on oral health, including

An Increased Risk of Tooth Decay

Saliva helps to flush away food particles and bacteria from teeth; without enough saliva production, food particles and bacteria build up on teeth, leading to decay.

Increased Risk of Gum Disease

Saliva plays an essential role in maintaining the health of gums. Without enough saliva, gums may become inflamed and infected – ultimately leading to gum disease.

Bad Breath

Dry mouth can contribute to bad breath by encouraging bacteria growth within the mouth. 

Dry mouth can increase bad breath due to bacteria growing within it. For best results when managing this with sleep apnea treatment options. 

Tips for Managing Dry Mouth

Managing dry mouth is of vital importance when treating oral health conditions such as sleep apnea. Below are some helpful tips: 

Stay Hydrated

To keep your mouth hydrated and combat dryness and increase saliva production, aim to drink at least 8 glasses of water daily – at a minimum! Sipping water regularly will help fight dryness while stimulating salivation production.

Avoid Drying Substances

Alcohol, caffeine, and tobacco can exacerbate dry mouth symptoms by dehydrating the body and decreasing saliva flow. Therefore, to manage dryness more effectively, it’s wise to limit or avoid their consumption in order to alleviate it.

Saliva Replacement Products

Saliva replacement products can be found over-the-counter and by prescription and can mimic the cleansing properties of saliva to provide relief from dry mouth. Mouth rinses designed specifically to address this condition may also provide additional lubrication.

Employ a Humidifier

Add moisture back into the air with a humidifier in the bedroom during sleep to combat dryness, creating a more relaxing sleeping environment and alleviating symptoms. 

Other Dental Effects of Sleep Apnea

Sleep apnea can lead to dry mouth as well as other dental complications, including:


Bruxism, also known as teeth grinding or clenching, is a parafunctional habit characterized by the habitual clenching or grinding of the teeth for no discernible purpose other than compensatory mechanisms in response to sleep apnea events. 

Bruxism typically occurs during sleep, so you’ll remain unaware of this behavior until it leads to wear on teeth wear, fractures, or loss, as well as jaw pain or headaches. 

Gum Disease (Periodontal Disease)

Gum disease affects both gums and bones that support teeth. Sleep apnea increases your risk for gum disease which may ultimately result in tooth loss.

TMJ Disorder

Temporomandibular joint disorder, more commonly referred to as TMJ refers to any condition affecting the temporomandibular joint that connects the jawbone with the skull. Teeth grinding during sleep apnea episodes can contribute to its development or worsen it.

The common symptoms of TMJ may include jaw pain, difficulty opening or closing the mouth fully, clicking or popping sounds in joints, and headaches, which can significantly impair daily activities such as eating, speaking, or sleeping.

Tips for Sustaining Oral Health with Sleep Apnea

In order to promote oral health while managing sleep apnea, follow these helpful tips:

Schedule Regular Dental Check-Ups

It is wise to visit your dentist, ideally every six months, in order to keep an eye on your oral health and detect and intervene early in case any dental issues related to sleep apnea arise.

Regular examinations also allow early identification and intervention in case any problems emerge that require attention from medical providers.

Sleep Apnea Treatment Devices

Work closely with your sleep specialist to identify an effective remedy for sleep apnea, such as an oral appliance or CPAP machine, which will keep the airway open during sleep, thereby decreasing apnea episodes and their impact on oral health.

Good Oral Hygiene Practices

Use a soft-bristled toothbrush with fluoride toothpaste at least twice each day to thoroughly brush all tooth surfaces and the gum line, with particular focus on cleaning between the teeth. Also use a tongue brush that that scoops out bad bacteria and makes room for healthy mouth microbiomes.

Also, floss regularly to remove plaque and food particles between them and use an antimicrobial mouthwash to kill bacteria and freshen breath.

Nightguard or Splint

If you suffer from bruxism, your dentist may recommend a custom-fitted nightguard or splint for optimal protection of both upper and lower teeth from grinding forces.

This provides a protective barrier between upper and lower jaws to withstand grinding action and alleviate symptoms such as jaw pain. By wearing one regularly, you may reduce wear on teeth, fractures, as well as alleviate associated symptoms like jaw ache.

Additional Considerations

The Importance of Open Communication Between Your Sleep Specialist and Dentist

It is vital that there be open communication between a sleep specialist and dentist when treating sleep apnea; your dentist must know about any potential interactions between devices used to treat it and dental work that might interfere.

Potential Interactions Between Sleep Apnea Treatment Devices and Dental Work 

Sleep apnea treatment devices, like oral appliances, may interfere with dental work, and therefore, it’s essential that any such decisions be discussed with your dentist prior to beginning any sleep apnea treatments.

Impact of Untreated Sleep Apnea on Overall Oral Health

Untreated sleep apnea can have an enormous effect on overall oral health, from dental complications such as tooth grinding and jaw alignment to cardiovascular disease risk, diabetes, and inflammation- all of which have the potential to have detrimental results. 

Diet Recommendations for Oral Health and Sleep Apnea

A balanced diet rich in fruits, vegetables, and lean proteins is key for maintaining oral health. Such food provides essential vitamins like A, C, and D as well as calcium, which are vital components in keeping teeth and gums in good condition.

Foods that promote saliva production and hydration, like sugar-free chewing gum or foods rich in water content, may also help treat your sleep apnea. Saliva works to wash away food particles and bacteria, potentially helping prevent tooth decay or gum disease.

Final Thoughts

In conclusion, if you suffer from sleep apnea, it can have severe effects on your oral health. It is crucial that steps are taken to manage this condition and maintain good oral hygiene. By following the tips outlined above, you can reduce sleep apnea and boost oral health.
