Minimal Intervention Dentistry (MID) is a philosophy focused on preserving natural tooth structure and promoting oral health through early detection, prevention, and minimally invasive treatments. Instead of the traditional approach of removing tooth decay and filling cavities, MID emphasizes preventing decay in the first place, remineralizing early lesions, and using the least invasive techniques when intervention is necessary. This approach aims to maintain teeth functional for life by minimizing tissue damage and maximizing the tooth's natural ability to heal.
