Dental sinusitis : Dental ozone therapy and sinusitis

Sinusitis and Toothache: What Natural Solutions Can Help You Heal?

Introduction

Do you suffer from recurrent sinus infections and also experience dental problems? This may not be a coincidence. The upper teeth especially the molars and premolars are located just beneath the maxillary sinus. A dental infection can therefore easily spread to the sinus and cause sinusitis of dental origin.

In this context, ozone therapy, a technique using medical ozone, is gaining attention as a complementary option. It offers benefits in dentistry and fits naturally into holistic approaches for sinusitis care.

Sinusitis and Teeth

The maxillary sinuses are cavities located above the roots of the upper teeth. In some people, the wall separating them is very thin. As a result:

• A deep cavity,

• A root infection,

• A complicated dental procedure,

• Or a tooth extraction,

can allow bacteria to pass into the sinus.

This leads to odontogenic sinusitis, which often affects only one side of the face.
➡️ Studies estimate that around 40% of unilateral maxillary sinusitis cases are of dental origin (Fokkens et al., World Journal of Otorhinolaryngology, 2024).

Dental Sinusitis: Symptoms

Symptoms may include:

• Nasal congestion or purulent discharge on one side,

• Facial pain, sometimes radiating to the teeth,

• Bad odor or unpleasant taste in the mouth,

• A recent history of dental treatment or extraction.

A dentist or ENT specialist can confirm the diagnosis through clinical examination and a 3D scan (CBCT).

Dental Sinusitis: Duration

Dental sinusitis is linked to a dental infection affecting the maxillary sinus. Its duration usually ranges from a few days to several weeks, depending on how quickly treatment is initiated. Without appropriate dental care, it can become chronic and may require antibiotics, drainage, or rapid and targeted odontological intervention by a professional.

Maxillary Sinusitis

Maxillary sinusitis refers to inflammation of the sinus located beneath the eye. It causes facial pain, nasal congestion, and dental pressure. Its duration depends on whether the cause is viral, bacterial, or allergic, ranging from one week to several weeks, with a risk of recurrence if proper treatment and regular medical follow-up are not ensured.

Sinusitis-Related Tooth Pain: Ozone Treatment

Ozone therapy uses ozone (O₃), a special form of oxygen with the following properties:

• Antibacterial: eliminates bacteria, viruses, and fungi,

• Anti-inflammatory: reduces inflammation,

• Healing: stimulates tissue regeneration.

In dentistry, ozone can be applied:

• In gaseous form,

• As ozonated water, for example using an ozone dental irrigator,

• Or as ozonated oil, found in certain toothpastes such as Ozonic.

➡️ A review published in BMC Oral Health (2025) reports that ozone therapy reduces postoperative pain and accelerates healing after certain dental procedures.

Benefits of Dental Ozone Therapy

Research shows that ozone can:

• Help disinfect root canals during endodontic treatments,

• Reduce pain after certain procedures,

• Promote healing after tooth extraction,

• Improve gum health in periodontal disease.

➡️ Bocci et al. (Ozone Therapy in Medicine and Dentistry, 2019) highlight that ozone acts rapidly against bacteria resistant to antibiotics.

Sinusitis and Ozone Therapy: A Complementary Natural Approach

Ozone therapy does not replace the primary treatment of dental sinusitis (which remains the treatment or repair of the affected tooth), but it can:

• Reduce bacterial load after dental treatment,

• Decrease sinus inflammation,

• Accelerate the closure of an oral–sinus communication following extraction.

➡️ A study by Petrucci et al. (International Journal of Dentistry, 2023) suggests that ozone used in nasal or dental irrigation may improve recovery after treatment of oroantral communication.

How the Treatment Is Carried Out

1. Consultation and diagnosis: confirmation of the dental origin of sinusitis.

2. Necessary dental care: root canal treatment, extraction, or repair.

3. Ozone application: directly on the tooth or gum, or via irrigation with ozonated water.

4. Medical follow-up: to ensure healing and prevent recurrence.

Conclusion

The link between dental problems and sinusitis is very real. Good oral health is essential to prevent certain forms of sinusitis. Dental ozone therapy and sinusitis can form a winning combination: dental care treats the cause, while ozone helps speed up healing and limit infection as part of a more natural approach. Aquolab offers natural ozone-based treatments that complement dental care and can be used at home.

If you suffer from persistent sinusitis on one side, consider consulting your dentist as well the cause may lie there.
