How To Treat Malocclusions and Sleep Disorders
Posted on 3/2/2026 by Everglades Family Dental |
 Many people might not realize that the way their teeth fit together (or don't fit together!) can actually affect their sleep. A bad bite, also known as a malocclusion, can sometimes contribute to sleep disorders like sleep apnea. Let's explore how these two issues can be connected and what can be done about them.
Understanding Malocclusions
Malocclusion is a fancy word for teeth that are misaligned. This means your upper and lower teeth don't come together properly when you bite down. There are different types of malocclusions, including:
| • |
Overbite: When your upper front teeth significantly overlap your lower front teeth. |
| • |
Underbite: When your lower front teeth protrude beyond your upper front teeth. |
| • |
Crossbite: When some of your upper teeth bite inside your lower teeth. |
| • |
Open bite: When your front teeth don't meet when you bite down. |
| • |
Crowding: When there isn't enough room in your jaw for all your teeth, causing them to overlap. |
These misalignments can cause a variety of problems, including difficulty chewing, jaw pain, headaches, and even speech difficulties.
The Link Between Malocclusions and Sleep Disorders
While not all malocclusions lead to sleep disorders, certain types can increase the risk. One of the most common sleep disorders linked to malocclusions is obstructive sleep apnea (OSA). OSA happens when the muscles in the back of your throat relax during sleep, causing your airway to become blocked. This blockage leads to pauses in breathing, which can disrupt your sleep and cause serious health problems.
How does a malocclusion contribute to this? Certain jaw positions, often associated with underbites or severe overbites, can narrow the airway, making it more susceptible to collapse during sleep. Additionally, a recessed lower jaw can push the tongue back, further obstructing the airway.
Identifying Potential Issues
If you suspect you might have a malocclusion or a sleep disorder, there are several signs to look out for. Signs of malocclusion include difficulty chewing, jaw pain, frequent headaches, and visible misalignment of your teeth. Signs of a sleep disorder like OSA include:
| • |
Loud snoring |
| • |
Pauses in breathing during sleep (often noticed by a partner) |
| • |
Daytime sleepiness |
| • |
Morning headaches |
| • |
Difficulty concentrating |
If you experience any of these symptoms, it's important to seek professional help.
Addressing Malocclusions and Sleep Problems
The good news is that both malocclusions and sleep disorders can be effectively managed. Treatment options will depend on the specific type and severity of the malocclusion and the sleep disorder.
For malocclusions, options may include orthodontic appliances to gradually shift the teeth into a more favorable position. In some cases, orthognathic surgery (corrective jaw surgery) may be recommended to reposition the jaws and improve the bite.
For sleep disorders like OSA, treatment options can range from lifestyle changes (such as weight loss and avoiding alcohol before bed) to using a continuous positive airway pressure (CPAP) machine, which helps keep the airway open during sleep. Oral appliances, custom-fitted mouthguards that reposition the jaw and tongue, can also be a very effective treatment option, especially for mild to moderate OSA.
Working with a dentist or orthodontist can help determine the best course of action for addressing your specific needs. Sometimes, a team approach involving both a dentist and a sleep specialist is necessary to achieve optimal results. The goal is to improve your bite, open your airway, and help you get a good night's sleep! |
