VA dental care at 100%: what Class IV actually requires
Veterans rated 100%, or paid at the 100% rate through individual unemployability, may be eligible for any needed VA dental care, verify with your VA dental clinic.
The rule, straight from the regulation
38 CFR §17.161(h) defines Class IV: veterans whose service-connected disabilities are rated at 100% by schedular evaluation, or who are paid at the 100% rate by reason of individual unemployability, may be authorized any needed dental treatment.
Two things follow. First, TDIU is a real door: a veteran paid at the 100% rate through individual unemployability qualifies the same as a schedular 100%. Second, permanent and total status is not required, which third-party guides very often state wrong. A temporary 100% rating, for example during convalescence, is the exception that does not qualify.
The other dental doors
Class IV is the rating-gated door, but the dental classes cover more ground: a compensable service-connected dental condition, dental trauma from service, former prisoner-of-war status, participation in a Chapter 31 program, and dental conditions aggravating a service-connected condition each have their own class with their own rules.
Your VA dental clinic and VA health eligibility decide the class and the care. Verify your own eligibility there; this page maps the doors, it does not open one.
