A nutrition scientist has offered some top tips to people who want to avoid emergency dentistry and keep all their teeth.
Dr Ed Blonz from the University of California told the Mercury News that the essential ingredients for strong teeth are calcium, phosphorous, magnesium, vitamin D and a little fluoride.
However, he also warned that it is vital to take good care of them from the outside too, brushing away sugar that can cause bacteria to breed and flossing.
When asked how essential flossing is, Dr Blonz joked that people should only floss the teeth they want to keep.
Brushing twice a day for at least two minutes and flossing once every 24 hours is the recommended advice from dentists.
Last month, Dr Ogo Eze told the Guardian that people should be careful they are not too vigorous with their toothbrush, as this can actually cause the gums to recede.
