According to a review of the scientific evidence over the past 150 years, the effects of fluoride toothpaste, good oral hygiene and health education, might override the effects of food alone on tooth decay.

Professor Monty Duggal, an author of the review, said that it’s not enough to just look at what we eat when talking about tooth decay, as other factors seem to be as important.

Fluoride toothpaste changes the effect that some foods have on the teeth, as do other good oral hygiene practices''.

“Future research should investigate a number of lifestyle factors together with different foods that might affect tooth decay. Times have changed and with that, the foods we eat, and how we care for our teeth,” Duggal said.

The overall aim of the review was to look at the evidence for the claim that sugar was the main cause of dental caries (tooth decay).

The researchers concluded that out of 31 studies carefully reviewed, the majority did not find a relationship between the amount of sugar consumed and dental caries, but the frequency of consumption may be important.

Most people now know the best way to prevent tooth decay is to brush with fluoride toothpaste twice a day, especially before going to bed, courtesy dental health education.
