New 'massage method' quadruples protection against tooth decay

Do you really want to avoid cavities in your teeth? Try massaging them with a high-fluoride toothpaste after lunch.
Eight years ago a new brand of toothpaste was launched in Sweden with more than three times as much fluoride as standard toothpaste. Available without prescription, it is aimed primarily at those with high caries risk.
Researchers at the University of Gothenburg's Sahlgrenska Academy have now performed the first scientific evaluation of the effect of this so called "high-fluoride toothpaste". The study has resulted in a new method that quadruples the level of protection from fluoride.
In the study, 16 volunteers tested a variety of brushing techniques, using either high-fluoride or standard toothpaste, and brushing either two or three times a day. "The study revealed that those who used a high-fluoride toothpaste three times a day had four times better fluoride protection in the mouth than those who used standard toothpaste twice a day," says researcher Anna Nordström from the Institute of Odontology at the Sahlgrenska Academy.
Also tested was a new method developed in collaboration with professor Dowen Birkhed, which involves rubbing toothpaste onto your teeth with a finger. "This 'massage' method proved to be at least as effective as a third brushing in increasing the amount of fluoride in the mouth," Anna Nordström explains. "Rubbing the front of your teeth with toothpaste can be an easy way of giving your teeth a third "shot" of fluoride during the day, after lunch for example. But this should not replace brushing with a fluoride toothpaste morning and evening it's an extra."
Brushing with fluoride toothpaste has played and continues to play a major role in combating tooth decay, and there is strong scientific evidence that daily use of fluoride toothpaste has a pronounced preventive effect.
