HELP OR HINDRANCE?
Taking a daily vitamin supplement is as natural nowadays as, well, brushing our teeth — but did you know they could be damaging our dental health? A study by the University of Helsinki on eight types of effervescent vitamins revealed that all of them had corrosive effects on teeth due to their primary ingredient, citric acid. By leaching out the minerals, teeth were left weaker and more porous and as a result more prone to decay. Fizzy vitamin C tablets were the worst offender, exposing dentine, the sensitive layer beneath enamel. To minimise the damage, don’t swish the drink around your mouth and rinse with water afterwards. Nibbling on cheese can also help as it has an alkaline pH that can reduce acid levels and put minerals back into teeth.
