If you've noticed unusual bony bumps in your mouth, you might be experiencing an exostosis. While the term might sound alarming, these growths are generally benign and rarely cause significant issues. They are considered a variation of normal anatomy, and most individuals live with them without any complications.
Types and Causes of Oral Exostoses:
The location of an exostosis determines its classification. The most common types include:
Torus Palatinus: A bony growth found on the roof of the mouth. It often appears as a single growth.
Torus Mandibularis: Bony protrusions located under the tongue, typically on both sides (bilateral).
Buccal Exostoses: Hard bony bumps on the outside of the gums, less common than the other types and also often bilateral.
The exact cause of exostoses is not definitively known, but several factors are believed to contribute to their development. These include:
Genetic Predisposition: A tendency to develop exostoses can run in families.
Environmental Factors: While not fully understood, environmental influences may play a role.
Masticatory Hyperfunction: Excessive chewing force can stimulate bone growth.
Bruxism: Teeth grinding or clenching can also contribute to the formation of exostoses.
Continued Jawbone Growth: Ongoing growth of the jawbone may also lead to these formations.
Exostoses typically emerge in the late teens or early adulthood and may gradually increase in size over time. Many individuals may not even notice their presence for years.
Diagnosis by Dental Professionals:
Dental professionals usually diagnose exostoses during routine dental check-ups. During a structural assessment, if thickened or protruding bone is observed, the dentist may document its size and appearance with photos or measurements to monitor any changes over time.
Health Concerns and Potential Issues:
For the vast majority of people, exostoses pose no health concerns. However, in rare instances, they can lead to adverse effects, particularly if they become significantly large. Potential issues include:
Speech Interference: A very large torus mandibularis can occasionally impede clear speech.
Tissue Irritation: The thin tissue covering exostoses is susceptible to scratches or injury from sharp foods, which can result in ulcers.
Denture Placement: All types of exostoses can interfere with the proper fit and placement of dentures, if a patient requires them.
Aesthetic Concerns: Some individuals may opt for removal due to cosmetic reasons.
Treatment for Oral Exostoses:
Treatment for exostoses is generally only recommended if they interfere with oral function or present an aesthetic concern. When removal is necessary, it is typically performed by an oral surgeon in a dental office. The procedure usually involves:
Local Anesthesia: The area around the exostosis is numbed.
Incision and Tissue Retraction: An incision is made, and the soft tissue is gently lifted to expose the bone overgrowth.
Bone Reshaping: The excess bone is carefully trimmed using a high-speed dental tool or, in some cases, a dental laser.
Suture Placement: The soft tissue is then sutured back into place.
Maintaining Oral Hygiene with Exostoses:
Regardless of whether you have exostoses, maintaining excellent oral hygiene is crucial for overall mouth health. This includes:
Brushing: Brush your teeth at least twice daily.
Interdental Cleaning: Floss or use interdental brushes or water flossers at least once a day to clean between teeth.
Rinsing and Scraping: Consider using antimicrobial mouthrinses and tongue scrapers.
Regular Dental Check-ups: Visit your dental professional for regular cleanings and examinations. They can monitor the health and size of any exostoses and offer specific recommendations for your needs.
Food Particle Removal: Be diligent in checking for and removing any food particles that might get lodged between the exostosis and your gums.
While the discovery of an exostosis might initially cause alarm, understanding that these growths are usually harmless can bring peace of mind. If you are unsure about any growth in your mouth, it is always best to consult a dental professional to rule out any more serious conditions. With good oral hygiene and regular dental visits, you can maintain a healthy, happy smile.
