Well, I bit the bullet and went to see my orthodontist yesterday (after putting it off for 3 months) I feel like my jaws are regressing a bit, so I wanted to get it taken care of if I could. He told me that my tongue is pressing against my lower teeth. Then he proceeded to drill a hole in the middle of my retainer. His years of experience tell him that since my tongue has a mind of its own that it will be amused by this odd shape and will leave my teeth alone. We shall see.
