Dr Moore, have you ever seen patients complain of illness after a composite dental filling was placed? I had a filling done behind my front tooth and have been feeling very unwell ever since. I felt absolutely fine before the filling was placed but since then have been getting very bad headaches, brain fog and a general feeling of un-wellness. The material used was called Venus Flow but I am told it cannot be removed. Can a tooth be removed to rid the problem if the material is impossible to remove? Thanks.
