Bolton's Law (Bolton's Principle)

Bolton's Law, often referred to as Bolton's Principle, states that the size discrepancies between teeth should be proportional in relation to each other to maintain a balanced and aesthetically pleasing alignment in dental orthodontics. Specifically, it highlights that the width of the upper front teeth (incisors) should be compared to the width of the lower front teeth, suggesting that these proportions should remain constant. This principle is crucial for orthodontists when planning treatments, ensuring that dental alignment not only enhances function but also achieves an attractive smile.
