Smile design in dentistry is a customized approach to enhancing a person’s smile through a series of aesthetic and functional improvements. It involves assessing various factors such as tooth shape, size, color, alignment, and gum health to create a personalized treatment plan. Techniques may include teeth whitening, veneers, bonding, crowns, and orthodontics. Digital simulations often help visualize the end result before treatment begins. The goal is to achieve a smile that looks natural, balanced, and aligned with the patient’s facial features, while also ensuring optimal dental function and health.
