Hello, I am on my 13th trays of invisalign. I went to change my trays Friday night and noticed that on my upper new trays there is an "indent" missing for an attachment! The tray does not fully cover this tooth. I called the office Friday night and even though they were open, the receptionist would not call the dentist and I had to call back on Monday. Are you kidding me! I wore the new trays and now the tooth with the attachment, but no indent on the new tray, hurts. Please tell me what I should do now. I'm going to call again first thing Monday morning. I am also using Acceledent so I change trays weekly, which scares me even more.Thanks.
