Buying advice

When choosing a fluoride gel or foam, consider your specific needs: if you are at high risk for cavities, opt for a prescription-strength product like Clinpro 5000. For sensitive teeth, choose a gel with potassium nitrate, such as Ultradent UltraEZ. Foams are generally less messy and better for gag-sensitive patients, while gels adhere longer. Always check compatibility with dental restorations (e.g., avoid APF on porcelain). Products in this category are professional-grade and often require a dentist's recommendation; verify with your dental professional before use.
