Lamictal and lunch

I was on Lamictal for 4 years and after the first year I suddenly started having all kinds of teeth and gum problems for no discernible reason. But since Lamictal has the possible side effect of "sores or blisters on the inside of the mouth" I wondered if it could be related.

I did a Google search and am coming up with no experts yet, but lots and lots of posts connecting anticonvulsant meds, particularly Lamictal, Topamax, Neurontin, and Depakote, with dental problems. Dilantin is well known for causing gum disease and breaking down tooth enamel, loosening of teeth, and even breaking down of jawbone tissue.

I don't think the experts have connected the dots yet, but is anyone else having this problem?
