I think realistically, there's not many people who have a completely sugar-free diet. So my personal number one tip would be control the frequency of your sugary snacks as opposed to the total amount. If we think about how the tooth decay forms, it's because of the sugar that's feeding the bacteria that's causing that tooth decay. If you're constantly feeding the bacteria sugar, it'll be constantly causing tooth decay and the tooth themselves can't repair. So little changes such as having your dessert straight after your dinner or making sure that we're not snacking a bag of sweets over a period of two hours and actually eating it in a short amount of time will mean that the tooth has then got time to repair itself.
