DENTISTS MAKE a pretty big deal about fluoride and how good it is for your teeth. Truly, fluoride is the best cavity fighter out there, helping our teeth stay healthy and strong! But how exactly does fluoride do such an awesome job at keeping our mouths cavity-free?

Fluoride Prevents and Repairs Tooth Decay

Bacteria that are in plaque produce acids that seep into tooth enamel and break it down. This process of breaking down enamel is what causes cavities over time. Where plaque breaks down the tooth, fluoride builds it up.  Fluoride, a mineral that occurs naturally in many foods and water, protects teeth from cavity-causing bacteria by making tooth enamel more resistant to bacteria’s acid attacks.

Fluoride also helps repair tooth decay in its early stages by building up the tooth in a process called remineralization. This cavity-fighting mineral even reduces the ability of plaque bacteria to produce acid in the first place!

Fluoride is Available in a Variety of Forms

Fluoride can be directly applied to the teeth through fluoridated toothpastes. In fact, toothpaste with fluoride has been responsible for a significant drop in cavities since 1960.
Our office also offer fluoride application to teeth as a varnish. Getting a fluoride treatment periodically is important because it contains a higher concentration of fluoride than toothpaste can give.







Fluoride Intake is Important at All Ages

Exposure to fluoride can be especially beneficial for infants and children. Between the ages of six months and 16 years, fluoride becomes incorporated into the developing permanent teeth, protecting them from cavity-causing bacteria.

However, adults and children alike need to get enough fluoride to protect their teeth. Just as important as strengthening developing teeth is fighting tooth decay, which fluoride will help you do even after your permanent teeth have come in.

Increased exposure to fluoride can be beneficial for people with certain health conditions. For example, if you have dry mouth, gum disease or a history of frequent cavities, your dentist may recommend additional fluoride treatments or supplements. Ask us if you could benefit from additional fluoride.

The Portland area’s water is mostly non-fluoridated.  There are some areas in Beaverton that are fluoridated, but most areas need to make sure they are getting adequate amounts as we don’t have it in our water.  We generally recommend that using a fluoride toothpaste is adequate for most children and teenagers, along with our regular fluoride varnish at the end of your dental appointment.

Tooth Decay Is Preventable
