Relationship between tooth infection and tinnitus.

Studies do suggest that tooth infection can cause tinnitus. Impacted wisdom teeth and Tooth abscesses can cause ringing in the ears. But mostly tinnitus caused by abscess usually fades with time and requires no further treatment.

The mechanism of ringing in the ear due to tooth infection involves increased blood flow through the ears which causes tinnitus. infection in the tooth causes increased heart rate increasing the blood flow through the ears and ultimately causing ringing in the ear.

Secondly, Inflammation in the tooth due to abscess causes temporomandibular dysfunction which also leads to tinnitus. this tinnitus caused by TMJ dysfunction is cured as the condition is treated by a dentist.

Furthermore, the removal of impacted and infected wisdom teeth can also cause tinnitus and hearing loss.

Studies have also confirmed that an infection in the upper third molar tooth can cause ringing in the ear. Tinnitus caused by these conditions can be treated with dental procedures and usually, it heals over time.

Tinnitus is also caused by many other dental problems such as Bruxism. Mercury fillings, Dental drills, ultrasonic plaque removal, etc

Pyorrhea is a condition associated with pus discharge from gums. it affects gums and bones. It is also a cause of Meniere’s disease and tinnitus. Pyorrhea is often caused by gum damage as a result of toothpick use.

Bruxism is the involuntary clenching of jaws and grinding of teeth. this condition also causes temporomandibular joint dysfunction ultimately leading to Tinnitus. this can be relieved by using mouthguards.

Dental Fillings are composed of 50% of mercury and about 30% silver. Since mercury causes neurotoxicity it causes tinnitus and hearing loss

Dental Drills are a source of high pitch noise. this noise is transmitted to the inner ear through bone conduction and it causes the intensity to become even high. this noise can cause tinnitus. using earplugs and anesthesia also does not prevent tinnitus during dental drills. Short splurges of 5-10 seconds are recommended rather than long sessions,

Ultrasonic Plaque Removal Use of high-frequency ultrasonic tools is also responsible for tinnitus in some patients. therefore compliance with mechanical tools is greater than with ultrasound tools in patients.

Can Tooth Decay Cause Tinnitus

While tooth decay and tinnitus are two separate conditions, there is some evidence to suggest that tooth decay and other dental problems may be contributing factors to tinnitus. This may be due to the fact that some of the same bacteria that cause tooth decay can also affect the inner ear and contribute to inflammation, which can lead to tinnitus. However, more research is needed to determine the specific relationship between tooth decay and tinnitus.

Other Causes of tinnitus

Tinnitus or ringing in the ear might also be caused by many other conditions such as

  • Age-related hearing loss
  • meniere’s disease
  • Some medications like antibiotics and antidepressants
