Birmingham Dentistry Done Right
The Standard Has Changed.
Built for Patients Who Want More
Vulcan City Dental is an independently owned general dentistry practice at the crossroads of Birmingham, Crestline, Mountain Brook, Irondale, and Crestwood — founded in 2025 by Dr. Michael MacWilliam and Dr. Caitlin Grimes.
After a decade of practicing inside corporate dental environments, they made a deliberate choice: to build something different from the ground up. Not a better version of what already existed. A replacement for it.
Every system, every piece of technology, and every protocol at this practice was designed around one organizing principle: patients who understand what's happening in their own mouth make better decisions and have better outcomes. That means you'll see your own diagnostics on screen in real time, hear honest pros and cons for every option available to you, and never be asked to accept a recommendation you don't fully understand.
There's no corporate office setting quotas here. No production targets shaping your care plan. Just two doctors who answer to their own clinical judgment — and to you.
What Makes Us Different
" I really enjoyed my experience at Vulcan City Dental! The team was kind, thorough, and efficient. I highly recommend to anyone looking for a pleasant experience at the dentist."
"The facility was very neat and clean. The staff were super awesome. I went in to get a crown on I was missing. Michael came in and made his magic. He pays attention to every small detail to match the crown to original teeth. If I could give more stars I would because not only did they bring my smile back but also my confidence."
"Absolutely wonderful staff and experience. Madison was my hygienist. Dr. Mac was my dentist. Both took their time, were thorough and I truly felt so great after I left! The machines there are also incredible. 10/10 recommend."
"Truly incredible dental care. I went in for a filling I had due to grinding my teeth and not only did I get the filling (and the whole process was painless) but Dr. MacWilliam identified the root cause of the problem with the help of their 3D equipment (something no other dentist had identified) and fixed it. Plus they were able to make me a night guard really easily with the same equipment. I highly recommend this practice. Both dentists are incredibly kind and knowledgeable."
"Great experience! Clean facility with amazing staff. Kaila is the definition of the perfect office administrator, dental hygienist was super sweet and efficient. Dr. Grimes is an amazing dentist, she is very knowledgeable and explained everything to me very simple and clear. I would recommend Vulcan City Dental to anyone."
"Vulcan City Dental is such a great dentist office! Dr. Mac fit me into his schedule the next day after I chipped my tooth and was able to fix my problem. The office staff are super friendly and helpful as well. 10/10 experience and I will most definitely be using them for all of my future services!"
