What Dental Issues Cause Snoring & Can it be Treated?

Snoring can be linked to oral health. Misaligned teeth, an overbite, or a small jaw can narrow the airway — and some causes can be managed with dental treatment.

Reviewed by the clinical team at The Smile Designer·Preston, Melbourne·5 min read

You may wonder how snoring could have anything to do with oral health. Snoring is a common problem caused by a variety of factors, including dental issues. Misaligned teeth, a large overbite, or a small jaw can contribute to snoring by narrowing the airway and making it harder for air to flow freely. If you or a loved one are experiencing snoring, it may be helpful to consult a family dentist in Preston, Thornbury, or Northcote to determine if jaw or teeth issues are contributing to the problem.

Common causes of snoring

  1. Obstruction in the airway — deviated septum, enlarged tonsils or adenoids, or nasal polyps can block airflow.
  2. Weight gain — extra tissue in the throat can narrow the airway.
  3. Alcohol consumption — alcohol relaxes throat muscles, increasing airway obstruction.
  4. Smoking — causes swelling and inflammation in the airway.
  5. Sleep position — sleeping on your back allows the tongue and soft palate to collapse backward.
  6. Dental issues — misaligned teeth, overbites, and small jaws can reduce airway space.
  7. Age — throat muscles weaken over time, making them more prone to collapse.

Dental concerns that affect snoring

Misaligned jaw

A misaligned jaw narrows the airway, making airflow more difficult and causing the soft tissues of the throat to vibrate, producing snoring. It can also create tension in jaw and throat muscles. Your dentist can help identify the problem and recommend corrective treatment, such as jaw repositioning splints.

Missing or broken teeth

Missing teeth can shift surrounding teeth, narrowing the airway and causing soft tissue vibration that leads to snoring. Broken teeth can similarly affect jaw alignment. Treatments like dental implants, bridges, or All-on-4 implants can restore missing teeth, stabilise the jaw, and reduce snoring.

Teeth grinding (bruxism)

Grinding your teeth puts pressure on the jaw and surrounding muscles, causing misalignment and airway narrowing. Bruxism can also wear down teeth, changing the bite and increasing snoring risks. Your dentist may recommend night guards or jaw repositioning splints to protect your teeth and relieve airway pressure.

Crowded teeth

Crowded teeth can push against each other, altering jaw alignment and narrowing the airway. This tension can also affect the shape of the soft palate and tongue, contributing to snoring. Orthodontic treatments like braces or Invisalign can correct crowding and improve airway function.

Why see a dentist for snoring

Dentists have the expertise to assess jaw structure, teeth alignment, and oral function, allowing them to identify causes of airway obstruction. Common dental treatments to reduce snoring include dental implants for missing teeth, bridges to restore gaps, night guards for teeth grinding, jaw repositioning splints, and orthodontic solutions such as braces or Invisalign. Dentists can also refer patients to sleep specialists for further evaluation, helping to prevent serious conditions like sleep apnoea.
