If you wear hearing aids for hearing loss, you will need to replace your hearing aids every three to seven years. For some people, their hearing aids will last longer, and for some, it will be a shorter amount of time. This will depend on how long you wear your hearing aids, how the hearing aids were manufactured, and how well you maintain your hearing aids. If you are not sure how long it has been since you have had your hearing aids replaced, you can contact your hearing care professional where you got your hearing aids from. They should have a complete record of your hearing care.
