Hands down the best, straight forward, and professional dental experience for an invasive and awkward procedure. I had a front tooth in need of an implant which, when sitting with Dr. Armstrong, was straight forward and concise in his evaluation of the steps needed to completion. I wouldn’t recommend another DDS to, not only walk me through the 90 day procedure of this, but also he personally and promptly returned calls for additional questions. A true professional in his field.

It’s incredibly simple to explain the polar opposite reviews of Dr. Armstrong: Poor reviews – are from patients who are used to a bubbly hygienist talking more than cleaning your teeth and a dentist who walks in for 30 seconds and compliments you on your beautiful smile. If this is the type of dental experience your desire, I agree that you should NOT see Dr. Armstrong Great reviews – are from patients who have a passion for their teeth and want to hear the honest truth, not fluff. Dr. Armstrong conducts your entire visit, cleaning and all, and does not sugar coat. If all is well with your mouth, he will only see you twice a year, he wants to make that time effective! I have never had such a thorough cleaning and I agree it was rougher than any other cleaning I’ve had in my life; I also had more plaque removed from my mouth than I’ve ever had (and I get regular 6 month cleanings.)

Craig is a great doctor/dentist. There is something to be said when you can get (almost) everything done in one place. I went in to get a crown but the tooth was cracked so it needed to be removed, unfortunately. That was all taken care of within one visit with the highest level of expertise and professionalism by Craig himself. Now I’ll be putting in an implant which again will be handled entirely by Craig. He is as good as it gets.

I just finished having major work done on my teeth. I had what Dr. Armstrong coined as “a smile adjustment” which included gum surgery, new caps, new veneers, an implant, and several crowns to replace old amalgam fillings. This process took over a year or two (mostly by my choice) and I have been very pleased. You have to realize that before I was a patient of Dr. Armstrong, I had extreme anxiety when going to the dentist. Because of his gentleness and positive attitude I have been able to go for cleanings and minor work with no anxiety at all. A big part of the great atmosphere at his office is because of Shiela, his assistant and jack of all trades. Thanks to both of you.

Doctor Armstrong truly cares for his patients. It’s clear he takes great pride in his work, making sure to work out all the fine details. I always leave his office feeling like I’ve been taken care of by a passionate person and dentist. Always a delight speaking with Sheila as well. Great practice, highly recommend.

Dr. Armstrong is very knowledgeable on modern techniques, very professional, and always very friendly. I have been going to Dr. Armstrong for over twenty year and would not change for anything. I had major problems from the orthodontist that I had when I was a teen. Dr. Armstrong has repaired the damage and my mouth has been trouble free for many years. I do not know of a better dentist anywhere!

Dr. Armstrong is a GREAT DENTIST!!! I agree with the several positive posted reviews regarding Dr. Armstrong. My self and my family have been patients for many years. I have NO PROBLEM with the dental cleanings as I understand that brushing and flossing daily is critical to keep my teeth. I also know for a fact that the gums and teeth are two different situations. I was told at one point in my life, (by a different dentist) if I did not floss and brush daily I would have dentures soon. I had bleeding, sore, red gums. I can not express enough thanks to Dr. Armstrong, who is one in a few general dentists, that he does all of the different dental procedures to keep ahead of MY dental health with his cleanings and all of my dental care. Dr. Armstrong has always and still is working on my behalf for me to keep my teeth. He talks to me very directly, tells it like it is for my benefit. I appreciate this about him. The receptionist is great also, I have never had any problem with my account, insurance etc. Always greeted in a cheerful way, making me feel very welcome as I come in the office. Both Dr. Armstrong and his receptionist are great people there taking great care of me and my family. Also what is up with you Yelp, how does only the negative reviews show up and not the positive ones that you have filtered. People should be able to also see these other reviews.

Dr. Armstrong is very knowledgeable and caring. I haven’t had any bad experiences with him in the seven years I have received care from him and I don’t understand the bad reviews. He has been able to pinpoint my dental problems and fix them at a reasonable cost. I have serious dental issues that can cause me to lose my teeth and knowing that he is there for me to save those teeth gives me peace of mind. He cares about the way I take care of my teeth and if he sees I haven’t been he will call me on it. He has been a dentist for decades, does everything in his office, and has never ripped me off. He has diagnosed problems that other dentists wouldn’t or didn’t. I can trust him and afford him. This is what I love about Dr. Armstrong.

Dr. Armstrong is a GREAT DENTIST!!! I have been a patient for 10 years. I am grateful for his passion to take the BEST care of his patients. I appreciate the way he cleans my teeth. As I want to keep my teeth. When he is done I know they are cleaned the ultimate best. He does his cleanings the exact way a specialist dentist cleans teeth. Again I WANT TO KEEP MY TEETH. I know it is also my responsibility to floss and brush daily to keep my teeth and my body healthy. When I do brush and floss daily my gums are healthy, and do not hurt after he cleans my teeth!! I look forward to having him clean my teeth. He explains very well where I understand all the procedures he does, as Dr. Armstrong does all of the dental procedures . I know for a fact that what ever needs to be done it will all be done with excellence. He discusses with me, matter of fact manner, exactly what is happening, why and how to take care of everything that needs to be done. I definitely recommend Dr. Armstrong to other people that want to keep their teeth and have the very best dental care.

Dr. Armstrong is a great professional. Ive read a lot of other people’s comments about him being rude, and that simply isn’t true. He’a been my dentist for more than five years. And while he is direct and to the point, like most people from the East Coast, it is because of his expertise that he emphasizes to a patient where they need to pay more attention to their mouth – like brushing or flossing Some people in Denver might find that rude, but it simply isn’t.

Dr. Armstrong is a great Dentist! This is my 4th time getting my teeth cleaned from him, my wife also gets her dental work done by him. Jack can be a little harsh both verbally and while he’s working on your teeth. However, it’s because he truly cares about your health and wants to best for his patients. If you’re looking for a gentle dentist who holds your hand and doesn’t take care of you because your’re a whiner, Dr. Armstrong isn’t your guy. But if you’re looking for a great dentist that ensures your best health at a decent price (but can be a little harsh) give his very nice and helpful assistant, Sheila, a call!
