It seems that mothers intake of vitamin C during pregnancy has a big time effect on child’s teeth.
Maybe by nature you have a bigger need for vitamin C and so does your child?
Try giving him at least 500mg of vitamin C per day, if not even more. Split that amount into smaller doses, given always with after a meal, and better to give it as calcium-ascorbate then ascorbic acid.
Also, bad teeth are sometimes caused by slow thyroid, which can be caused by all kinds of things - like lack of iodine in food. Use only salt which has iodine and try some iodine rich foods (salmon for instance).
