Fluoride mouthwash is one of my favorite dental products. It is affordable, easy to use, and dramatically improves the health of those who need it.
ACT is my favorite fluoride rinse. It has a higher fluoride concentration so you only need to use it once a day vs twice like some brands.
Fluoride strengthens enamel making it more resistant to decay. Children and teens and some adults who have poor brushing habits may need the help of extra fluoride. Others have a very good brushing and flossing routine, but are just more cavity prone.
Braces are difficult to keep clean and teeth are vulnerable to decalcification during orthodontic treatment. Decalcification leaves a permanent mark on teeth and is the beginning of the decay process.
If your mouth is dry you don't have the benefit of saliva to buffer the acids in foods and liquids and are more prone to cavities.
Long term use of fluoride remineralizes tooth surfaces making them less sensitive.
Exposed root surfaces from receding gums are prone to sensitivity and tooth decay. Fluoride strengthens these vulnerable areas.
White, yellow or brown spots that can occur on any tooth surface but often occur near the gum line are called decalcification and are a result of poor brushing. These weak areas in your enamel can be strengthened with consistant use of a fluoride rinse.
The best time to rinse with fluoride is before bedtime. Your mouth is naturally dryer while you are sleeping and your teeth are more vulnerable to plaque during this time.
After brushing, swish with fluoride rinse for one minute. Spit and don't rinse with water, eat, or drink for 30 minutes.
The following are well known brands and good products. They may require rinsing twice a day due to a lower concentration of fluoride.
If you have gum problems in addition to being cavity prone one of these may be the better for you. Knowing what your dental needs are will help you make the best choice.
