How can dental problems impact hearing instruments?

Dental problems can have a significant impact on hearing instruments primarily through alterations in joint alignment and the resulting pressure that may develop. The temporomandibular joint (TMJ), which connects the jaw to the skull, is located near the ear. Issues such as misalignment or dysfunction in this joint can lead to discomfort and increased pressure in the vicinity of the ear. This pressure can affect the functioning and fit of hearing instruments, making them uncomfortable or less effective.

When the alignment of the jaw is altered due to dental issues, it can lead to symptoms such as ear fullness, discomfort, or even tinnitus, all of which can affect how a person perceives sound through their hearing aids. Furthermore, if the hearing aids are not properly fitted or if the pressure around the ears fluctuates, the effectiveness of the hearing instruments may be compromised, leading to a decrease in sound quality and clarity.

While other factors like ear infections, increased earwax production, and changes in the external auditory canal (EAC) size can affect hearing and hearing instruments, these are less commonly related to dental problems compared to the joint alignment issue directly linked to the TMJ.
