I have genetic hypodontia of my upper lateral incisors, removed bony impacted wisdom teeth, and one impacted upper canine tooth, and genetic dental pitting.
When "birth-marks" became recently again irritated from something, the statistical connection between my epilepsy, shagreen patches, teeth, and Asperger's Syndrome more strongly pointed to Tuberous Sclerosis Syndrome (TSS) as the more central source for many of the impairments.
I brush and floss my teeth regularly, but my last dental visit was in early 1977 through a charity program that charged back to Medicaid. Between 1977 and 1987, income and university disqualified coverage, and after 1987, no available dentists accepted SSI Medicaid, and just today (Sep. 17, 2011), I received a California Medicaid letter stating that the "program is sending you this letter to tell you that it no longer covers dental, chiropractic and podiatry benefits for adults."
By federal law, I think Medicaid still mandates dental coverage for genetic dental disorders, but the "proof" of genetic disorders is expensive, and then, Medicaid pays denists so little, they didn't/haven't offered/accepted services under Medicaid anyway. More dentists did participate in "Dentists Without Borders" than did accept Medicaid, so Catch-22 with the borders too.
