After INBRACE treatment has been completed and your smile is just as you'd like it, you still need to wear a retainer at night as part of their teeth straightening treatment process. This is because it takes time for the upper and lower jaws to re-learn how they fit together. If you stop using the retainers before the teeth are ready, your teeth can start moving back towards their original alignment and impact the results achieved with treatment. A retainer may be a metal and acrylic frame that snaps over the dental arch or a clear, tray-like retainer that fits onto the teeth and is more discreet. The one most appropriate for your smile can be discussed during one of your last few appointments.
