Why it matters for dental
Dentists recommending or selling herbal toothpastes should know that fluoride content, antibacterial performance, and cytotoxicity vary widely across commercial products, potentially affecting caries prevention and soft-tissue safety.
Key points
- Study evaluated multiple commercial herbal toothpastes for fluoride concentration, antibacterial activity against oral pathogens, and cytotoxicity in cell-culture models.
- Findings link lower fluoride content in some herbal formulations to reduced anti-caries efficacy compared with standard fluoridated controls.
- Cytotoxicity assays identified dose-dependent cell viability reduction in certain products, raising questions for patients with mucosal sensitivity or compromised barriers.
- Results provide an evidence base for clinicians discussing product selection with patients seeking fluoride-free or botanical alternatives.
