Confusing cracked tooth pain with sinus/TMD/atypical facial pain
What it is
Misdiagnosing a cracked tooth (or cracked cusp) as non-odontogenic pain (sinusitis, temporomandibular disorder/myofascial pain, neuropathic "atypical" pain), or the reverse — treating a non-odontogenic pain as a dental problem (restoration/RCT/extraction) because the patient reports "toothache."
Why it happens
• Pain is hard to localize: cracked tooth pain can be intermittent, sharp, and "moves," making tooth identification difficult • Referred pain mimics toothache: myofascial/TMD pain can refer to teeth, and often does not respond to tooth provocation (cold, percussion on the suspected tooth) • Incomplete testing: skipping bite testing, transillumination, periodontal mapping, or relying on one test (these are key in cracked tooth workup) • Cognitive shortcut: "sinus season" / "patient has TMD" becomes the anchor → conflicting dental signs get discounted (non-odontogenic toothache literature warns against irreversible dental procedures when the pain source is non-dental)
