Healthy gums are the foundation of a strong, confident smile. At Cardinal Dental, we believe that advanced periodontal care doesn't have to be intimidating.
While our expertise is clinical, our approach is lighthearted and gentle - because your comfort is just as important as your health.
When gum tissue becomes irritated or infected, it can affect more than your mouth, it can impact your overall health, comfort, and daily life.
Cardinal Dental periodontal care focuses on early detection, gentle treatment, and long-term prevention. Our specialized periodontal care is designed to treat gum disease with a gentle touch and expert precision.
Whether you’re noticing bleeding gums, sensitivity, or just want to protect your smile, we’re here to help you restore and maintain optimal gum health.
We use only certified dental equipment and materials according to international standards.
Our highly qualified medical team performs a variety of dental procedures, varying from extractions with socket preservation and bone grafting to sinus lift, gingival grafting and implant retained dentures.



Periodontal disease is a serious gum and bone infection that damages soft tissue and destroys the bone that supports your teeth. Periodontal diseases can range from a simple gum infection to a more serious disease state. If periodontal disease is not treated pain, inflammation, tooth mobility, pain, and tooth loss.
Taking a proactive approach to gum health is essential for your overall well-being. We use advanced diagnostics to identify the stage of gum disease and create a personalized plan to restore lost tissue, preserve your natural teeth, and provide a strong foundation for a healthy life.

Great experience every time I go.
Front desk staff is very welcoming. Hygienists are all knowledgeable and caring. Dr. Blalock is so nice, makes sure she sees her patients in a timely manner, and even sings to you sometimes.

Absolutely amazing experience!
Super friendly for my young toddlers and very supportive of me trying to handle them all during the appointments. Dr. Even took my kids who weren't getting their cleaning on an "adventure" to help make sure everyone was getting what they needed. Dentist was great with the kids and informative on things that were concerning to me. Love Cardinal dental for my family!

Best dentist I’ve ever been to.
Everyone is super friendly! Everyone is sooooo friendly and make you feel like you’re their family💜 100/10 recommended ! Thank you so much

I am glad I was recommended this office.
Cardinal Dental has been my one stop shop for anything to deal with my teeth. Everyone there is charming and professional and it is credit to their continued work towards excellence.

The individuals who work here are amazing.
I haven’t went to the dentist in over 6 years and I was terrified to go. I must have asked a million questions to my dentist and technicians, they answered all of them and broke it down for me to understand. They even had enlarged pictures of my x-rays to really explain what they were talking about.
The front desk and billing section was painless as well. They answered it all and it really felt like they cared (they did).

Most places say they will go above and beyond. No one is going to beat this one.
I took my daughter here for an Invisalign appointment today. I was so impressed with the staff and this doctor that I will be moving my entire family to utilize the full dental services that are offered here.
Too many things to mention- taking the extra time, the entire staff incredibly knowledgeable, everyone is friendly and truly cares and values your time and who you are as a person. They make you feel good and you actually want to go back….. to the dentist!! I would rate more stars if I could. Thank you Dr. Blalock for taking exceptional care of my daughter today. We will be back soon.


Dr. Blalock and her entire staff are PHENOMENAL.
They create such a fun, relaxed, and welcoming environment. They work hard to make sure your kiddo (or the adults as well!) feel comfortable and calm, making adjustments as needed. We live 45 minutes away from the office but I find it 100% worth the drive for such outstanding care!

Wherever you are on your journey, we can help :)
