You most likely will have heard this answer before but it is very important. Brushing your teeth at least twice a day with a fluoride-containing toothpaste or ideally after each meal will go a long way in protecting your oral health from decaying. As well as limiting sugary and oily foods such as sweets, crisps, fried chips etc. A piece of advice you may not have heard from however, is considering dental sealants. Ask your dentist about this to see if they offer this treatment.
