When Tristen Boyer recently visited her dentist for a couple of cavity fillings, she was advised to get fluoride treatment as an added precaution. At just 22 years old, this University of Kentucky student also faces an increased risk of tooth decay due to Crohn’s disease.
“I think it’s a good idea to get it done,” Tristen said. “I plan on continuing with it.”
Many dental professionals recommend fluoride treatments to help prevent cavities and strengthen teeth. This straightforward process usually involves applying a varnish, gel, or foam directly to the teeth. However, it can be a bit tricky as insurance often doesn’t cover these treatments, especially for adults.
So, how does one determine if fluoride treatment is necessary?
Who Might Benefit from Fluoride Treatments?
For individuals at high risk of tooth decay, professional fluoride treatments can be very beneficial. As Dr. Robert Weyant from the University of Pittsburgh points out, “If you haven’t had any decay in years, you’re probably okay. What you’re doing at home is likely sufficient.”
Your dentist will consider your history with cavities and might inquire about your eating habits, such as if you consume a lot of sugary drinks and how you take care of your oral health.
People who lack access to fluoridated water, do not use fluoride toothpaste, or skip flossing regularly might want to consider fluoride treatments, according to Dr. Alex Daniel of Johns Hopkins University.
Certain demographics could benefit from fluoride more than others. For example, women who are going through menopause often experience hormonal changes that can impact their oral health. Additionally, individuals taking certain medications might suffer from dry mouth, leading to a rise in bacteria and tooth decay.
For those deemed at risk, dentists generally suggest fluoride treatments every three, six, or twelve months.
The Benefits and Drawbacks of Fluoride Treatment
Fluoride helps prevent decay by strengthening tooth enamel, which is the hard outer layer of the tooth. Dr. Matthew Messina, an Ohio dentist and spokesperson for the American Dental Association, explains, “Acid from bacteria can weaken the enamel, leading to cavities, but fluoride helps make the enamel tougher.”
Though most studies highlight the effectiveness of fluoride for children, there is ongoing debate about its benefits for adults due to the lesser amount of research done in that area. Dental professionals find the treatment to have no significant safety concerns, with the only rare side effect being fluorosis, which may cause slight discoloration of teeth from excessive fluoride exposure.
An emerging concern regarding fluoride has recently been brought to light, with some public figures questioning its safety, including Robert F. Kennedy Jr. However, dental experts assure that using fluoride toothpaste, drinking fluoridated water, and receiving occasional fluoride treatments generally keeps fluoride levels within safe limits.
Is Fluoride Treatment Worth It?
Fluoride treatment can cost between $25 to $55. While many insurance plans cover these treatments for children, adults are often left to pay out-of-pocket.
Tristen, who had fluoride treatments as a child, paid $30 for her first adult treatment. She expressed a wish that insurance helped cover these costs but believes it’s a worthwhile investment to prevent cavities, costly dental procedures, and potential tooth loss.
“We only have one set of teeth,” she stated. “The longer we can keep them, the better.”
