Dear Mr. Dubois,
Thank you for posting your request on History Hub!
We suggest that you review How to Find Old Medical Records and How to Get Copies of Your Medical Records websites for research tips for how to locate the civilian dental records since this information was not included in your Army medical records.
For questions about pay for Army personnel (active duty/reserve/guard/separated), please contact the Defense Finance & Accounting Services (DFAS-Indianapolis) via their website at https://www.dfas.mil/customerservice.html.
We hope this is helpful.
