Once you have identified a free legal aid program that provides dentures for seniors, you will need to complete an application process. This typically involves filling out an application form and providing the necessary documentation to prove your eligibility. Some programs may require an in-person assessment or consultation to determine your oral health needs. Once your application is approved, you will be placed on a waiting list until dentures become available. The waiting period may vary depending on the program and the demand for dentures in your area. It is important to be patient during this process and follow up with the program regularly to check on the status of your application.
