After any orthodontic treatment, whether it be Invisalign or conventional braces, you need retainers to hold your teeth in their new positions and keep them straight.
Why wear retainers?
There is a very high likelihood of the movement of teeth after braces are removed or after Invisalign treatment, particularly within the first few months. This is because the gums and bone around your teeth need to readjust and firm up.
Also, as we age, our face matures and our jaws continue to change shape, which may result in tooth movement or crowding of the lower front teeth. Some people even believe the eruption of wisdom teeth can cause the teeth to be “pushed” forward; however, research does not substantiate this theory, as tooth movement can still occur whether you’ve had wisdom teeth removed or not.
