Thank you for your feedback, Doctor! We're glad to hear you find the Dental Model useful for patient education. The MD-105 model is specifically designed for tooth brushing demonstrations, and we appreciate your suggestion. For a model that includes caries and other dental conditions, we recommend the iDENTical Patient Education Model (Caries, Implant, Nerves) M2001-3, which might be a better fit for explaining diseases and conditions. We value your input and will continue to improve our offerings.
