Teeth Straightening and Sleep Apnea: Can Orthodontic Treatment Help?

Can orthondtic treatment helps cure sleep apnea?

Orthodontic treatment is commonly associated with improving the aesthetic appearance of teeth. However, orthodontic treatment can also have health benefits beyond just improving one's smile. In this blog, we will explore the relationship between teeth straightening and sleep apnea, and whether orthodontic treatment can help alleviate the symptoms of this condition.

What is Sleep Apnea?

Before we dive into the relationship between teeth straightening and sleep apnea, let's first understand what sleep apnea is. Sleep apnea is a sleep disorder characterized by pauses in breathing or shallow breaths during sleep. These pauses can last anywhere from a few seconds to minutes and can occur multiple times throughout the night. The most common type of sleep apnea is obstructive sleep apnea (OSA), which occurs when the muscles in the back of the throat fail to keep the airway open.

Symptoms of sleep apnea include:

  • Loud snoring
  • Gasping or choking during sleep
  • Excessive daytime sleepiness
  • Morning headaches
  • Difficulty concentrating

This constriction can be caused by various factors, including genetics, obesity, and structural issues with the jaw and teeth. If left untreated, sleep apnea can lead to more serious health problems, such as high blood pressure, heart disease, and stroke.

While there are several treatments available for sleep apnea, many people are interested in finding alternative solutions, such as orthodontic treatment

The Link between Teeth and Sleep Apnea

Before we delve into the potential benefits of orthodontic treatment for sleep apnea, it's important to understand the connection between teeth and this sleep disorder.

One of the main causes of sleep apnea is an obstructed airway. This obstruction can be caused by a number of factors, including excess weight, enlarged tonsils, or a deviated septum. However, research has also suggested that misaligned teeth and jaws can contribute to sleep apnea by causing the airway to become partially or completely blocked during sleep.

When a person's teeth are not aligned properly, it can lead to an improper bite, also known as malocclusion. Malocclusion can cause the upper and lower jaws to be out of alignment, which can in turn narrow the airway and make it harder to breathe. This can result in snoring and, in some cases, sleep apnea. In fact, a study published in the Journal of Clinical Sleep Medicine found that patients with severe obstructive sleep apnea were more likely to have dental crowding and a smaller upper jaw.

How Can Orthodontic Treatments Help Sleep Apnea?

Orthodontic treatment, such as braces or clear aligners, can help correct misaligned teeth and improve the alignment of the jaw. This can lead to an increase in the size of the airway, which can reduce or eliminate sleep apnea symptoms.

In addition to orthodontic treatment, there are other dental interventions that can help alleviate sleep apnea symptoms. For example, a mandibular advancement device (MAD) can be worn during sleep to reposition the jaw and keep the airway open. MADs have been shown to be effective in treating mild to moderate cases of sleep apnea.

Another study published in the American Journal of Orthodontics and Dentofacial Orthopedics found that orthognathic surgery was an effective treatment for obstructive sleep apnea in patients with jaw abnormalities.


It is important to note that orthodontic treatment alone may not be sufficient to treat sleep apnea. If you suspect that you have sleep apnea, it is important to speak with a medical professional for a proper diagnosis and treatment plan. Other treatments for sleep apnea include continuous positive airway pressure (CPAP) therapy, oral appliances, and surgery. The best course of action will depend on the individual patient's needs and the severity of their sleep apnea.

Final Thoughts

In conclusion, teeth straightening can play a role in the treatment of sleep apnea by improving the alignment of the jaw and increasing the size of the airway. If you are struggling with sleep apnea and have crooked teeth or a misaligned jaw, orthodontic treatment may be worth considering. But always speak to a professional if your condition is worsening.


Can teeth straightening help with sleep apnea?

Yes, teeth straightening can help with sleep apnea. In some cases, misaligned teeth or jaw structure can contribute to sleep apnea by blocking the airway. Straightening the teeth or correcting the jaw alignment can improve the airway and reduce the severity of sleep apnea.

How does teeth misalignment contribute to sleep apnea?

Teeth misalignment can contribute to sleep apnea by narrowing the airway and obstructing the flow of air. This can cause snoring and breathing difficulties during sleep, leading to interrupted sleep and daytime fatigue.

How long does orthodontic treatment for sleep apnea take?

The duration of orthodontic treatment for sleep apnea depends on the severity of the condition and the type of treatment. Braces or aligners typically take between 6 to 12 months to achieve the desired results, while oral appliances can provide immediate relief.

Is teeth straightening the only treatment for sleep apnea?

No, teeth straightening is not the only treatment for sleep apnea. Other treatments include lifestyle changes, such as losing weight and avoiding alcohol and sedatives, continuous positive airway pressure (CPAP) therapy, and surgery.
