Invisalign and fixed braces both straighten teeth and improve oral health, but they work differently. Understanding how each option fits your lifestyle helps you make the right decision. This guide explains the advantages, disadvantages, and key factors to consider so you can choose confidently.
What Is Invisalign?
Invisalign is a clear, removable aligner system designed to move teeth gradually. Each set of aligners is worn for 10–14 days. Aligners can be removed for eating, drinking, brushing, and flossing, but must be worn most of the day for effective results.
