Quick Summary

Fluoride is a safe and effective way to help protect your teeth. When combined with a caries risk assessment, it is a powerful tool for preventing cavities.

What is a Caries Risk Assessment?

A caries risk assessment is a way for your dental team to figure out how likely you are to develop cavities (also called dental caries). Everyone’s risk is different—it depends on things like: 

  • Your brushing and flossing habits 
  • Diet (especially sugary or acidic foods) 
  • Past history of cavities 
  • Saliva flow and oral bacteria levels 
  • Medical conditions or medications that affect oral health 

By understanding your risk, your dental team can create a personalized plan to protect your teeth. 

How Does a Caries Risk Assessment Work? 

  1. Questions & History: Your dentist or dental hygienist will ask about your dental and medical history, diet, and oral care routine. 
  2. Oral Exam: They’ll look at your teeth  for signs of early decay, wear, or other issues. 
  3. Tests if Needed: In some cases, saliva tests or bacterial assessments are done to get a clearer picture. 
  4. Risk Level & Plan: Based on the information, you’ll get a risk score—low, moderate, or high—and a tailored plan. This may include fluoride treatments, diet changes, or more frequent  dental hygiene visits. 

Why Fluoride Helps 

Fluoride is one of the easiest ways to protect your teeth, especially if your caries risk is moderate or high. Here’s why: 

  • Strengthens enamel: Makes your teeth more resistant to acids from foods and drinks. 
  • Remineralizes early damage: Helps repair enamel before cavities fully develop. 
  • Safe for all ages: Kids and adults alike can benefit from fluoride. 
  • Quick in-office treatments: Your dental team can apply fluoride varnish treatments  in just a few minutes for extra protection. 

Everyday Tips for Healthy Teeth 

  • Brush twice daily with fluoride toothpaste. 
  • Floss or clean interdentally daily to remove plaque between teeth. 
  • Eat a balanced diet and limit sugary snacks. 
  • Use a fluoride mouth rinse if recommended by your dental professional. 
  • Keep up with regular dental hygiene visits and professional fluoride treatments. 

A caries risk assessment + fluoride care is like giving your teeth a superhero shield. By knowing your risk and taking steps to protect your enamel, you can help keep your smile healthy, strong, and cavity-free for years to come!
