Worn out Invisalign retainer...what to do?
I would definitely recommend that you wear your last clear aligner. Your retainer is just a more durable, thicker, version of that same last aligner, so it is totally fine. Because aligners and clear retainers are made from a relatively thin polymer, they can loose their structural integrity with the slightest hole, break or tear in the material. This gives them less plasticity and more elasticity, which ultimately makes them unable to contain the minor movements of your teeth. I'm glad you're seeing your doctor very soon and it's a good idea to discuss your grinding issues with him, as well. I hope this answers your question and don't hesitate to ask me more.
