Are there any vitamin supplements that you can take that benefit your teeth? strengthen them? would calcium help? or such a thing as regenerating?

Nothing: No vitamins will strengthen adult teeth already formed, a good diet will help the gum and bones supporting the teeth. Various topical paste and rinses will help remineralize and strengthen the surface of the teeth.Hope that helps.

Mi paste: Healthy diets and vitamins will help, keep your gums healthy and this will help keep, your teeth strong. A healthy diet will have little sugars, soda and junk food to, decay teeth. Talk to, your dentist about a tooth conditioner called mi paste. This contains calcium and phosphate that the tooth enamel can absorb and make it harder. This is as close as we get to regenerating teeth.

no specific: Vitamins and calcium are helpful in general..Its good to have daily.But not specific for teeth strengthening.Eat healthy and you will be able to get all vitamins and minerals..
