Should I avoid sugar?: Mohinder Sira, Dental Hygienist
If you are having a lot of sugar in your diet, that sugar mixes with the plaque – produces acid, which start to attack your teeth, and that's how cavities are created.
So what we try and advise is, it's not the amount of sugar you eat, it's the frequencies - so if you are having sugar in your diet, keep it to your main three or four meals a day, rather than six to eight snacks throughout the day.
Because each time sugar enters your mouth, whether it's in food or drink, you will have a 30-40 minute attack on your teeth. The acidity level rises, and that's what can create the enamel to weaken and eventually, cavities can occur.
