This dentist and his assistants are truly as good as it gets.  I have had cleanings, fillings, crowns, and a root canal and have nothing but praise for this group. Dr Buchanan is extremely focused and careful in making a diagnosis and throughout the procedures. He has an amazing gentle touch. After using their deadening drops, the shots are painless. He spends as much time as it takes to get the perfect outcome. I am encouraging all my friends and family to switch to him. He is one of the few doctors I recommend without reservation.

I have been coming to Greystone Smile Design for a couple of years now, & every time that I come everyone there is absolutely amazing. Today I had the pleasure of having Casey clean my teeth & she is the BEST. I don’t see myself going anywhere else for my dental needs. (I even drive over an hour just to get there). Definitely the best in the business, with outstanding customer service.

So, on my travels for work last week I had a little dental mishap. I Googled local dentists and came across Greystone! I emailed their office through their website explaining what had happened and if they could please help me! I received a response first thing the next morning letting me know they could work me in! The entire staff was extremely nice and Dr. Buchanan did a beautiful job on my tooth and kept me from tears! I highly recommend this office for any of your dental needs! They have definitely earned my repeat business! Thank you!

My husband and I moved to the area almost two years ago. We were looking for a new dentist and found Greystone Smile Design! We are very happy we did! Dr. Buchanan is the most caring and carful dentist we’ve ever had! Let’s face it, the dentist isn’t ones favorite place to go… We’ll I really don’t mind going to this one! The staff is so nice, kind and sweet that they make it such a wonderful and comfortable environment to be in. They are also very informative! They know their stuff! Oh, and if that’s not enough, they put movies and TV shows on while you’re getting work done! Thank you Greystone Smile Design staff for taking care of my families pearly whites! They’ve never looked better!

Greystone Smile Design is a dedicated team of professional, knowledgeable, efficient, and compassionate staff led by Dr. Buchanan. Small, boutiquey office; great technology. Everyone in the practice works very hard to make a smile beautiful. I have never had such great care- and WANTED to go the dentist! All questions answered, everyone is polite, encouraging, never scary. Dr. B is very gentle, willing to answer all my questions, considers options and makes suggestions. Highly recommend!!

Stephen U. from Chelsea, AL (Source: Yelp)


I started going here because I got a Living Social coupon in my email. I had been without a dentist for almost 2 years. Never in my life did I expect to find my permanent dentist, but, I did. I would not go anywhere else, even if it were free. Everyone is SO nice and very helpful. I actually look forward to my next appointment. I cannot say enough good things about Dr. Buchanan and the entire staff. ABSOLUTELY POSITIVELY AMAZING only begins to describe each and every one of them. Do yourself and your teeth the best favor in the world and go see them right now!

Cathy J. from Birmingham, AL (Source: Yelp)


I’ve been a patient for several years. My daughter worked as an orthodontist assistant and had her own lab making retainers. She recommended Dr. Buchanan and I started going to him. He is very gentle and I’m not as stressed the way I used to be. He even pulled a tooth that had been giving me problems for over year and I didn’t know he was finished! His staff makes you feel at home. Highly recommended!

Dr. Buchanan and his team are awesome. During the COVID pandemic, my dental appointment was the first “non-essential” visit that I had when Birmingham reopened. I felt very safe and knew that they were taking every precaution to ensure the health of their patients and teammates. I would recommend this team to anyone and couldn’t imagine going elsewhere. That’s Dr. Buchanan and team… especially Dawn!

The staff at Greystone Smile Design are so friendly and personal! My daughters (6 yo and 4 yo) love going to the dentist because the staff makes them feel so comfortable. At our last appointment, one of the staff members held my 9 month old son while I got my teeth cleaned! They treat you like family.

I always have a positive experience with staff at Greystone Smile Design. Staff is very personable and professional. I trust Greystone Smile Design staff with all of my dental needs. I am originally from Madison WI and the dentists there were all about getting into my pocket book for things I truly did not need, for example caps on my teeth, they thought I should get at least 4 to 8 of them. Dr. Buchanan didn’t believe I needed no where near this many and he has always been straight up and honest about my dental needs, something I truly appreciate. Dr. Buchanan has a more conservative way of treatment for dental care. I highly recommend!

I’ve been going to Dr. Buchanan at Greystone Smile Design for roughly 3-4 years now. He is the best! I’ve never had to wait for more than five minutes after arriving to be seen (which is almost a shame because their lobby is incredibly welcoming and beautiful, with a tv and bottled water/coffee – you’ll find yourself wanting to linger here!). The technicians are the best in Birmingham. You know how you dread going to the dentist because every now and then someone “pokes” you or has a slip of the hand that makes it painful? That has literally NEVER happened here. Everyone from the front desk to the techs to Dr. Buchanan are excellent at what they do, and the office enviroment/vibe reflects this. I have referred several people to them, some of whom live 30 minutes away, and they are happy to make the drive to see the best dentist in bham!

I am a new patient to this office. Dr. Buchanan is the first dentist I’ve been to that hasn’t made me feel self-conscious or terrible about my teeth! He really takes the time to get to know you and make sure everything runs smoothly. I am glad I found this office and will continue to visit for all my dental needs.

The last several years I have been really impressed and thankful for the care that my family has gotten at Greystone Smile Design. We have four young kids and they have been very kind, patient, and gracious as they have cared for them and for my wife and I. They have earned our trust and we will happily continue to use them for our dental care!

Not only do I and my boys get the best care here but we drive two hours from where we live to see Dr Buchanan and his office staff. Dr Buchanan is conservative, kind, he listens, and I have never had a problem with any dental work I have ever had at Greystone Smiles. It’s not surprising that after trying many dentists, a couple of friends of mine recommended him. We have been there ever since! Best dentist there is for any member of the family no matter the age.

Very pleased with my crown, today. Dr. B is meticulous in fitting and finishing his work and very sensitive to pain management. Everyone is calm and relaxed setting the tone for we who they are serving. This is nothing new for me – always the same excellence. Highly recommend him to anyone reading this and considering changing providers.

I’ve had many dentists but Dr. Buchanan and his staff are tops in my book. Their appointment system is state of the art and makes great use of your time, with text and email reminders. Whether you are there for a dental problem or a standard cleaning, they will take care of you promptly and thoroughly. And no pain, only Greystone Smiles.

I went to Greystone Smile Design after Googling “dentist near me” and reading all the great reviews and Dr. Buchanan’s excellent credentials. My prior dentist moved out of town, and it was time for my 6-month cleaning. My prior dentist at my last cleaning and X-rays noted a suspicious area on one of my anchoring crowns of a 4-unit permanent bridge. She said I would need implants due to the teeth having had root canals. Yikes! I had just had 3 implants during the past 3 years and that was upsetting news for me and my bank account! I told her I’d prefer to wait 6 months and see if there was actually a problem, thinking to myself I would get a second opinion. I had my films sent to Dr. Buchanan for review prior to my first appointment. Much to my surprise, he said there was a problem but that he felt implants were too aggressive at this time and recommended bridge replacement. Everyone I’ve dealt with in the office has been great through the bridge process and a filling replacement. I could not be more pleased!

It is always an excellent experience when I visit your clinic. Every time I go to my appointment, I know I will be well cared and will have the most professional team that looks after the health of my teeth. I am so glad I found your practice and would definitely refer a family member or a friend to you. I want to thank you Dr Buchanan and your team for such a great job that you all do.

I absolutely love Greystone Smile Design! They are so personable and friendly! They also are very transparent with billing and caring for your dental needs. The hygienist are thorough when cleaning your teeth and they never pressure you to get any work done. They just lay out your options and give you their professional opinion in what work you need done, should there be any. Definitely staying with them until Dr. Buchanan retires!

Dave S. from Birmingham, AL (Source: Yelp)


I changed to Greystone Smile Design because of their Friday hours and a lost crown. The waiting room is comfortale, offering coffee and your choice of TV channels. Dr. Buchanan and his staff are hospitable and professional. They were conscious of my time, and did everything possible to prepare a new crown for me within the 45 minute planned appointment time. They also use up-to-date equipment that my previous dentist didn’t have. Lastly, Dr. Buchanan called me at 6:30 that evening to check on my pain level and crown fit. Overall, a very customer-friendly dentist. So far I’m very pleased and able to recommend them to others.

Eunice L. from Birmingham, AL (Source: Yelp)


Dr. Buchanan and his entire team are awesome! They see both of my teenage boys for dental care. They are friendly, professional and seem to relate to patients of any age range. I appreciate the warm environment they provide. My boys actually look forward to their six month check ups….THANK YOU GREYSTONE SMILE DESIGN!!! Eunice Loveless

The Dr is the most patient and caring person. I was always greeted by friendly staff on the phone, checking in, whoever has done my cleanings were so personable. I’ve had a major procedure and Dr B made sure that my experience was painless. We even had a few laughs because the TV was on above me during my procedure and I watched a funny movie with a headset on. Great experience for getting a crown and perfect work

On my travels for work last week I had a little dental mishap. I Googled local dentists and came across Greystone! Late Wednesday night I emailed their office through their website explaining what had happened and if they could please help me! I received a response first thing the next morning letting me know they could work me in! The entire staff was extremely nice and Dr. Buchanan did a beautiful job on my tooth and kept me from tears! I highly recommend this office for any of your dental needs! They have definitely earned my repeat business! Thank you!

We love Greystone Smile Design! They have always given great care for the entire family. On two separate occasions, Dr. Buchanan has gone above & beyond by attending to dental emergencies for our children after hours. The staff is so friendly, always happy to see you, and great with our kids! Would definitely recommend to anyone in the Birmingham area looking for a dentist!

I’ve been going to Greystone Smile Design for many years and have always had the absolute BEST experience. Dr. Trent Buchanan and his team are so professional and so knowledgeable. Their offices are gorgeous with plenty of parking, and it’s conveniently located right off Hwy. 280 in the Greystone neighborhood. Every member of this team is intent to serve you and make you feel comfortable. Quite simply – the best dental office in Birmingham.

Jeff D. from Greensboro, NC (Source: Yelp)


I love this place massage chairs friendly staff and outstanding service. Watch a movie while you get your work done. What’s that your not quite comfy ask for a pillow or a blanket they will be happy to get it for you. You can confirm your appointments by text if you like and they follow up with a call the following day. I am normally a pretty anxious fellow when I have to sit in the dental chair but here I am put at ease. I even chuckled when i saw the rendered what you could look like corrected dental photo for music artist Jewel. Check them out for your check up. You won’t regret it.

I had been seeing the same dentist all my life and then he retired.  I wasn’t fond of the person that was taking over his practice so I started looking for a new dentist. Friends recommended Greystone Smile Design and I have to say that I  love going to the dentist now!  Okay, maybe that is an overstatement but I don’t dread going to the dentist anymore.  Dr. Buchanan and his staff make sure you are comfortable with your cleaning and exam.  I had a filling done and there was no pain at all.  They will repeatedly ask you if you are okay or if you are feelign any discomfort.  Plus, there are massage chairs and movies to watch if you are there for a longer procedure.   They are always timely.  I never have to wait long to be seen by the hygienist or the doc.  If you want, they will send you email and text message reminders about upcoming appointments.  The office is in a beautiful building and is very clean and stylish.  They also have a full array of cosmetic dentistry options (whitening etc.) but I can’t speak for those services.

If there’s anyone out there who is my position I’m the ruts in a new town or city here in Birmingham and are looking for a great new family to start their Dental Care with!! Dr Buchanan at Greystone smile is your place!! On my first visits I was welcomed with so many warm smiles that I felt as though I was walking in to my parents house arriving at a family reunion!! Dr Buchanan sat alert and humbly as we went through the many discussions as to what I was looking for as far as results that I wanted to reach and he gave me that plan and I left so happy that I had my smile at the right hands with Dr Buchanan and staff at last!! This is a must go see Dentist Family!

Dr. Buchanan and his staff provide excellent dental care. I have been very pleased with every visit, whether it’s routine cleaning or filling a cavity. Dr. Buchanan’s assistants exhibit the skills and attitude that make it obvious they are providing the best care possible. Likewise, I would say that Dr. Buchanan is a perfectionist when it comes to performing any treatment such as filling cavities or placing crowns. He is very skilled and takes the time to ensure that everything is done extremely well.

I feel that I am getting high quality dental attention. The office staff is helpful and friendly. Dr. Buchanan only recommends procedures that are necessary. They also handle all of my dental insurance claims, and never ask for money before the insurance pays. As a matter of fact, I have not had any out of pocket expense so far. This has been my best dental experience in 25 years of living in Birmingham.

I had a great experience at Greystone Smile Design! Very professional and friendly staff! Dr. Buchanan was very friendly, efficient and great with my children. I have been to other dentists in the Birmingham area and have had horrible experiences! I’m am very happy I found them.. 5 stars!

I love Greystone Smile Design! Not only is the office so cute and home-y (they have the most adorable coffee station), but the staff are so incredibly nice and welcoming as well. My husband and I have been going there for a while now and we will not be going anywhere else! We’ve referred friends to go and they’ve had the best experience. Greystone Smile Design is extremely knowledgeable and I know I’m receiving the best care. I receive text/emails reminders and a follow-up after my appointment. They seriously make it such an enjoyable time!

I recently had a routine cleaning appointment at Greystone Smile Design. After my appointment, I wanted to write this review so that I can help anyone looking for a dentist. I have been going to Dr. Buchanan for years now. He has done implants and other routine procedures on me. I can not say enough about how great he and his staff are. If you are a person who gets nervous thinking about going to the dentist, I can assure you that this is the dental office for you. There is NOTHING scary about visiting this office or having ANY procedure!!! The entire staff are so reassuring and make you feel very comfortable. More importantly, Dr. Buchanan is highly skilled, HONEST and kind! I always say, “I feel sorry for people who do not know about Dr. Buchanan”.

I have been a patient of Trent Buchanan for over four years and refuse to go anywhere else. His staff I’ve learned to grow and love personally and they have treated me more than just as a patient but as a friend I will always refer anyone who ever ask me where do I go to have my teeth done. And it will always be the same answer Greystone smile design!

I have had dental disasters growing up, which led me to dread the dentist. Today that changed, I loved my visit at Greystone Smile Design! The ladies at the front desk were sweet and what really sold me was the care I received from Casey (dental hygienist) she listened to my concerns and talked me through the not so fun parts! Dr. B is pretty rad too! I definitely recommend this Office!
