If you lose an Invisalign tray, call Chapko & Shah Modern Dentistry at [practiceinfo field='prac_phone'] to schedule an appointment, so our dentists can decide on the next best step. Depending on your case, your dentist will order new trays for you, or have you move on to the next tray in the series. However, you shouldn’t make any decisions without contacting our Belvidere office first.
