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.

FAQ – Relationship Between Sinusitis and Dental Problems

🔹 Sinus / Teeth Relationship

What is the relationship between sinusitis and tooth pain?

The relationship between sinusitis and tooth pain is explained by the anatomical proximity between the maxillary sinuses and the roots of the upper teeth, particularly the molars and premolars. When the sinuses are inflamed or infected, the resulting pressure can cause pain that feels like a toothache, even in the absence of dental decay.

Is there a link between sinusitis and toothache?

Yes, the link between sinusitis and toothache is common. Inflammation of the sinuses can irritate the dental nerves, leading to diffuse pain, often bilateral or localized in the upper teeth.

Can dental problems be related to the sinuses?

Absolutely. Dental problems related to the sinuses mainly involve deep infections (advanced cavities, abscesses, pulp necrosis) that can spread to the maxillary sinuses and cause sinusitis of dental origin.

🔹 Sinusitis of Dental Origin

What is sinusitis of dental origin?

Sinusitis of dental origin is an inflammation of the maxillary sinuses caused by a dental infection. It accounts for a significant proportion of chronic unilateral sinusitis and requires treatment targeting the dental cause.

What are the symptoms of sinusitis of dental origin?

Symptoms include:

• persistent tooth pain (often unilateral),

• pressure under the eye or in the cheek,

• purulent nasal discharge,

• unpleasant oral or nasal odor,

• sinusitis that does not heal despite standard treatments.

How can you tell if sinusitis is of dental origin?

Several signs can suggest a dental origin: pain localized to a specific tooth, a history of recent dental treatment, chronic unilateral sinusitis, and confirmation through imaging (X-ray, cone beam CT).

Can a dental infection cause sinusitis?

Yes, a dental infection can cause sinusitis when bacteria reach the maxillary sinus through the tooth roots. Dental abscesses are a frequent cause of maxillary sinusitis of dental origin.

🔹 Tooth Pain Related to the Sinuses

Can sinusitis cause tooth pain?

Yes, sinusitis can cause tooth pain, especially in the upper teeth. Sinus pressure is often mistaken for typical dental pain.

Why does sinusitis cause pain in the upper teeth?

The upper teeth are located close to the maxillary sinuses. When these sinuses are congested or infected, the pressure irritates the nerve endings of the dental roots.

Can you have tooth pain without cavities because of sinusitis?

Yes, it is common to experience tooth pain without cavities when the pain is sinus-related. In such cases, several teeth may be sensitive at the same time.

🔹 Specific Symptoms and Atypical Forms

Is sinusitis with unilateral tooth pain suspicious?

Yes, sinusitis with unilateral tooth pain is highly suggestive of a dental origin. This is a key sign that should prompt a dental consultation.

Can sinusitis cause pain in the jaw or gums?

Yes, sinusitis can cause pain in the jaw, gums, or upper jaw due to the spread of inflammation.

🔹 Diagnosis: Sinus or Tooth?

How can you differentiate between dental pain and sinusitis?

Dental pain is usually localized to a specific tooth and worsens with chewing, whereas sinus-related pain is diffuse, associated with a feeling of pressure, and worsens with head movements.

How can you tell if tooth pain comes from the sinuses?

If several teeth are painful, with no visible signs of cavities, and the pain is accompanied by ENT symptoms (nasal congestion, facial pressure), the cause is likely sinus-related.

🔹 Treatment and Management

How is sinusitis of dental origin treated?

Treatment of sinusitis of dental origin is based on:

• eliminating the dental infection (dental treatment, root canal therapy, extraction),

• ENT treatment if necessary,

• sometimes targeted antibiotic therapy.

Should you consult a dentist or an ENT specialist for dental sinusitis?

Both may be necessary. The dentist treats the dental cause, while the ENT specialist manages the sinus inflammation. A coordinated approach is often essential.

🔹 Dental Ozone Therapy and Sinusitis (Natural Approach)

What is dental ozone therapy for sinusitis?

Dental ozone therapy uses medical ozone for its antibacterial, antifungal, antiviral, and anti-inflammatory properties. It effectively disinfects infected areas without systematically resorting to antibiotics.

What are the benefits of ozone in sinusitis of dental origin?

The benefits of ozone in sinusitis of dental origin include:

• rapid reduction of bacterial load,

• improved healing,

• decreased inflammation,

• support of natural defenses,

• a non-invasive and biocompatible approach.

Can ozone therapy replace antibiotics for sinusitis?

Ozone therapy does not always replace antibiotics, but it can reduce their use, particularly in localized, chronic, or recurrent infections, and in preventing complications.

Is ozone effective after a dental extraction or implant involving the sinuses?

Yes, ozone is particularly useful after a molar extraction, sinus lift, or dental implant, as it reduces the risk of sinus infection and promotes tissue regeneration.

🔹 Chronic and Recurrent Sinusitis

Can chronic sinusitis be caused by a dental problem?

Yes, chronic or recurrent sinusitis is very often linked to an untreated dental focus. As long as the dental cause persists, the sinusitis will not heal sustainably.

What should be done in cases of sinusitis that does not heal?

In cases of persistent sinusitis, it is essential to look for an underlying dental cause and consider complementary treatments such as dental ozone therapy.

🔹 Prevention

How can sinusitis of dental origin be prevented?

Prevention relies on:

• rigorous oral hygiene,

• early treatment of cavities,

• regular dental check-ups,

• preventive care such as ozone therapy to limit infections.
