My visit was proactive, to obtain a replacement retainer. (Having had my braces off for 10-yrs. I believe it prudent to obtain a standby.) I was directed to X-ray, which I questioned, and confirmed I did not require. Then advised, though I’ve remained a patient, my Ortho records had been destroyed, after 7yrs, therefore at the very least, a full set of photos would be needed. Doctor came in & assessed me, afterwhich a mold immediately made and 2 weeks later I had my new retainer.
