I have a quick question in regards to LOR from a dentist. I've been working at my orthodontic office for about a year now and my doctor is D.M.D/M.D, when they say a letter of recommendation letter from a general dentist, does it matter whether he is now a orthodontist? I mean all the doctors have specialized have their D.M.D degree, so I was thinking it would be the same. If anyone knows the answer please let me know. Thanks guys!
