How is it that women when pregnant frequently have crumbling tooth problems - I personally know 4 women including my sister who had molars partially crumble during pregnancy.
her doctor stated that this was due to nutrients either not being delivered to the tooth and/or essential nutrients/minerals being taken from the teeth and used during the babies development.
Teeth have a blood supply indicating that they like bone are constantly maintained and retain their white colour. Dead teeth are often dark grey in colour but can remain in the jaw without discomfort for years unless they become loose.
With proper nutrition and regular brushing teeth should require little interference from dentists.
Studies have shown that dentine allow the passage of calcium to the inner enamel surface of the tooth thereby reducing the possibility if infection from bacteria.
