Pathogenic bacteria in your mouth lead to tooth decay and gum disease. These kind of harmful bacteria can then spread into the blood and cause chronic health issues like heart disease and diabetes. Further, the bacteria can affect the blood vessels in the eyes and the brain, causing them to become inflamed—these vessels are linked to our hearing.
As sound waves arrive in the outer ear, they enter through the ear canal and cause the ear drum to vibrate. Through the ear drum, the sound waves travel into the middle ear causing the ossicles (tiny bones in the ear) to vibrate. As the sound reaches the innermost ear, it causes the fluid in the cochlea to move. The fluid and hair cells in the cochlea then create neural signals that are carried to the brain by the auditory nerve—the brain then interprets the sound.
All the above components are crucial for hearing and you’ll experience hearing problems if any of them fails to perform their function. Some of the most common complications are damaged hair cells, ruptured eardrums, otosclerosis and ear infections.
Not taking proper care of your oral hygiene can cause harmful bacteria to buildup around your teeth and gums. This can lead to dental diseases like periodontal disease and dental infection that can cause the bacteria to grow.
The bacteria can then enter your bloodstream and affect the flow of your bloodstream and form clots. The cells in the cochlea in your ear require a healthy blood flow to function at an optimum level—if the blood circulation is affected, the hair cells in the cochlea can get damaged or even destroyed, resulting in hearing loss.
Maintaining a proper oral hygiene is essential for your dental health and your auditory health. You don’t have to put in a lot of time and effort into it; you just have to be consistent.
Brushing teeth at least two times a day, using a brush with soft bristles, replacing your toothbrush every 3–4 months, flossing daily and regular dentist visits are just some ways in which you can look after your teeth.
