Can we grow a third set of teeth?

• Can we grow a third set of teeth?
• Current biological reality: Adults cannot naturally regenerate a third set of teeth; humans are limited to two sets (deciduous and permanent) due to our evolutionary development and stem cell exhaustion in dental tissue.
• Emerging research potential: Laboratory studies using stem cells and bioengineering show promise for future tooth regeneration or replacement therapies, but clinical applications remain years away from routine practice.
• Clinical implications: Dentists should manage patient expectations about viral claims of "regrowing teeth" and continue recommending evidence-based preventive care and established replacement options (implants, prosthetics) as standard treatment.
