Your question is one that most of my patients do ask. The key to Invisalign treatment with enamel stripping is very careful planning and in doing so, we avoid any bad side effects for your teeth and gums.
Enamel stripping or interproximal reduction, if done safely and carefully, does not cause any harm to your teeth. In fact, research has shown that teeth that have been stripped are not at a higher risk of decay or gum diseases compared to virgin teeth.
However (this is important), it must be done carefully, and within limits as not all teeth have equal thickness of enamel, and not all teeth have the same shape.
It is best to speak to your orthodontist to discuss where and why the stripping needs to be done.
Good luck!
