Fluoride Toothpaste Vs. Fluoride-free: Which Is Best?
Decades of research show that fluoride can effectively prevent tooth decay in children and adults by at least 25 percent. Fluoride offers many benefits, but it has a few disadvantages as well. This is especially true for younger children, who may accidentally consume more fluoride than is recommended when brushing their teeth. Your dentist can suggest the best type of toothpaste for you and your child.
What Is Fluoride?
Fluoride is a natural mineral that’s frequently found in water and certain types of food. It’s also added to some toothpastes and mouthwashes (you might see it listed as topical fluoride in these products.) This mineral is safe and effective when it’s consumed in safe amounts. Fluoride is most effective when it’s applied topically, which is why many dentists suggest spitting, rather than rinsing, after brushing or using fluorinated mouthwash.
Fluoride Toothpaste
Although fluoride is found in most public drinking water, the levels vary. For this reason, many dentists recommend toothpaste and/or mouthwash with fluoride to reach the recommended daily adequate intake for fluoride. According to the NIH, that number ranges from 0.01 to 3 milligrams depending on your age.
Pros
Fluoride effectively removes plaque buildup on the teeth and gums. Left in place, plaque can harden and turn into tartar, which increases your risk of developing cavities and gum disease. This natural mineral can prevent tooth decay or keep it from progressing.
Cons
Ingesting too much fluoride can potentially harm tooth enamel, especially in younger kids. This condition, called dental fluorosis, is prevalent among younger kids.
Fluoride-free Toothpaste
Although fluoride offers many benefits, and is recommended by many dentists, it might not be accessible or reasonable for everyone. This is often the case for younger children who have not yet learned to spit the toothpaste out after brushing.
Pros
With fluoride-free toothpaste, parents don’t have to worry about their kids accidentally swallowing too much fluoride.
Cons
Many children and adults don’t receive routine dental care, and might not understand the benefits of fluoride-free toothpaste. Dr. Yoshita Patel, DDS, MPH, explains that at the very least, community water fluoridation provides certain benefits. Patel reveals that fluoride levels are adjusted to remain within safe levels for adults and children. She also says that according to current research, tooth decay can increase up to 149 percent after stopping community water fluoridation.
