Well, a week after the excavations and all is well. My diet has changed some though; missing crushing teeth means fewer "crunchy" foods (as prescribed Doctor Harnish, rightly so; first couple of days with some suturing involved had "tender spots"). I am considering founding the "Pull Your Teeth Out, Lose Weight Diet Plan" (though it may already exist). The Doctor personally followed up with me the day after to see patient's condition. I was somewhat shocked and pleased that he took the time and that I could report no problems. Pre-procedure prep was handled thoroughly by Nichole (forgive me if names are changed; local anesthesia may have leaked into brain) including F2 race to watch during work from monitor mounted on the ceiling! Hadn't seen that race and must admit, almost fell asleep (typical when viewing Formula 1 races too; boring usually). Some tugging and sawing later, sutured up, gauze stuffed and I was out the door. Must admit to some trepidation pre-procedure, not having had much filling, grinding, digging done in the past (no cavities 'til age 40+) but wasn't really concerned. Nicole, the dental hygienist last year was great and Dr. Harnish instills confidence with his thoroughness and consideration of the patient which smoothed the way to completion. This is just Phase I of more to come here. In the meantime, the front of the office continues to be capably manned by Veronica and Kelly, who have guided me through the often opaque maze of finance and enrolled me in the Arch Dental Season Pass! That is all for now but for a related anecdote. Was at the NDSU Archives later that day and, on taking a drink from my bottled water, was convinced that the neck had broken on it! NO. Novocaine still doing its' thing. Didn't dribble though... p.s. should be illegal to have people named Nicole and Nichole in the same office; just sayin' p.p.s. pic below is of Skillet Fried Rice, just one of the new Mushy Meals Food Diet for Dental Patients* (patent pending) p.p.p.s. the second is of a Lady Bug p.p.p.p.s. really cool building (researches some at archives that day, and immaculately clean every time I have been there

I can’t say enough good things about Arch Dental, from how efficient the scheduling process was from the beginning, to how thorough my dental care has been. Arch Dental makes me feel comfortable at each appointment, to the point that I actually enjoy going! Dr. Harnish and the team are truly great at their craft.

I seriously can’t recommend Arch Dental enough. I’m a student in the area and dental visits used to make me super anxious, but they completely changed that for me. In just two visits they already have me feeling confident about my smile again. Everyone there is incredibly kind, patient, and explains everything in a way that actually makes sense instead of feeling overwhelming. You can tell they genuinely care about their patients and want you to feel comfortable. If you’re nervous about the dentist or have been putting it off, this is the place to go. So grateful I found them!!!
