Fluoride is not added to drinking water in Northern Ireland. Your local supply, however, may contain naturally occurring fluoride which finds its way into rivers lakes and reservoirs.
All adults and children should use a toothpaste containing fluoride.
Your dentist or a member of their team can apply topical fluorides during dental visits. These gels are more concentrated than self-applied fluorides, so they are not needed as often. Some adults can benefit from these applications. Fluoride gels can help to reduce dental decay.
If you are prone to dental decay, your dentist may advise the use of fluoride supplements in addition to fluoride toothpaste for extra protection. However, it is very important that fluoride supplements are only taken on the advice and instruction of your dentist.
