Invisalign straightens teeth using a series of clear, removable aligners that are changed every two weeks. The aligners work by gradually shifting teeth into their proper positions. The treatment focuses on moving specific teeth in small increments, which minimizes discomfort and ensures that the teeth are moved into the correct position. The aligners are virtually invisible and can be removed to eat, drink, and brush teeth, making them ideal for people who want to maintain their normal appearance while undergoing treatment.
