A denial for lack of a nexus or continuity of evidence is common when there's a documented gap between separation and the current diagnosis, especially for secondary conditions like TMJ linked to PTSD-related bruxism or jaw clenching. To strengthen a supplemental claim, the key missing piece is almost always a medical nexus opinion connecting the current TMJ diagnosis to the service-connected PTSD, not just lay belief that it isn't age-related degeneration.
Under 38 CFR 3.310, a secondary condition can be service connected if it is either caused or aggravated by an already service-connected disability. The examiner's own confirmation of a TMJ diagnosis is useful, but a Disability Benefits Questionnaire exam focused only on the claimed condition, without range-of-motion measurements or a clear rationale addressing etiology, often results in an inadequate exam. That inadequacy itself can be raised, but the faster path is usually obtaining a private nexus opinion (sometimes called an IMO) from a dentist or oral/maxillofacial specialist who can review the PTSD diagnosis, discuss the mechanism (clenching, grinding, stress-related bruxism), and state in terms of at least as likely as not that the TMJ is caused or aggravated by PTSD or its symptoms.

A buddy statement from someone who knew the veteran before and after service, noting jaw popping, clenching, or grinding they observed, can help establish continuity even without medical records from that period. A personal statement describing when jaw symptoms began, how they progressed, and their relationship to PTSD symptoms (nightmares, stress, teeth grinding during sleep) is also relevant lay evidence under 38 CFR 3.159.
The night guard prescription from six months ago is useful but thin on its own; pairing it with a dentist's narrative opinion addressing current bruxism, TMJ findings, and etiology will carry more weight. If the current exam was inadequate, that argument plus new nexus evidence can be submitted together.
For refiling, a VA Form 20-0995 (Supplemental Claim) is the correct form, since it requires new and relevant evidence rather than simply disagreeing with the prior decision. The next concrete step is scheduling an appointment with a dentist or TMJ specialist to obtain a written nexus opinion addressing the connection between PTSD-related bruxism and the diagnosed TMJ condition, then submitting that opinion along with VA Form 20-0995.
