It is a common desire to want straight teeth. But dentists will recommend orthodontics not because of aesthetics but because they want to correct the position of your teeth. It is an added bonus that putting your teeth in the correct position will also make them look nicer. Form will always follow function. If teeth are positioned where they should be then they will last longer, be easier to clean and be less likely to start wearing out and cause issues. Okay, so if I do braces then I’m done for the rest of my life, right? I never have to worry about my bite again? Wrong. This is why we get retainers once orthodontics is complete. Think of retainers as an insurance policy. We will always get relapse because of mesial drift (teeth tend to drift forward as we age) and the daily stress our teeth undergo. In addition, the ligaments around our teeth don’t settle as fast as our teeth do and will try to move things back. Retainers maintain your bite as much as possible and slow this process down. However, life happens and we often forget to wear our retainers or they break and we don’t get them replaced. So, our teeth start to shift again and we end up needing braces again later in life. But the idea of wearing metal braces as an adult is not very appealing. This is where Invisalign comes in.
