An Amazing Veneers Result
A Happy Smile Makeover Patient
Grant Smith, DDS, FAGD
Dr. Grant brings a cosmetic-focused approach to every patient interaction, pairing advanced training with a genuine commitment to listening. A graduate of the prestigious Kois Center and a Fellow of the Academy of General Dentistry, he's devoted years of continuing education to mastering the latest techniques in cosmetic and restorative care. When he's not in the office, you'll often find him supporting local organizations and finding new ways to give back.
Sharlenne Sumpter, DDS
Dr. Sharlenne is passionate about elevating the standard of care at our practice. Currently enrolled in the Kois Center's advanced curriculum, she pairs a sharp clinical eye with a warm, unhurried chairside manner. She also proudly serves the practice's Spanish-speaking patients in their preferred language, removing one more barrier between people and the care they deserve.
Mark Smith, DDS
Dr. Mark built this practice nearly 30 years ago on a simple philosophy: treat every patient the way you'd treat family. That foundation still guides everything we do today. While he continues to see patients on a part-time basis, his legacy of honest, relationship-driven care lives on through the team he's shaped and the loyalty he's earned across generations.
Flexible Payment Options
Fitting Into Every Budget
We believe the cost of care should never stand between you and the smile you want. While our practice operates on a fee-for-service basis, that doesn't mean you're on your own when it comes to navigating finances.
We accept the majority of PPO dental plans as an out-of-network provider, and our team handles the claims and reimbursement process. That means we file on your behalf, and your insurance plan reimburses you directly. Many of our Sherman patients are surprised by how much their plan still covers, even on an out-of-network basis.
For treatments not fully covered by insurance, or for patients without a plan, we also accept flexible financing through Cherry, including low- and no-interest payment options that let you move forward with care on a timeline that works for your budget.

Personalized Treatments You Can Trust
Our veneers are crafted from LiSi Press lithium disilicate porcelain, chosen for its strength and the way it refracts light like a real tooth. We work with Utah Valley Dental Lab, which is renowned for its aesthetics. Dr. Grant uses minimal-prep techniques whenever possible, preserving more of your natural tooth structure while still achieving a dramatic transformation.
A crown used to mean multiple appointments, messy impressions, and weeks in a temporary. With CEREC, we can scan, design, and mill your permanent crown right in the office in a single visit. The result is a precise, tooth-colored restoration that fits from day one, with no goopy molds and no waiting. Even with this added convenience, we work carefully to ensure your result will blend seamlessly with the rest of your smile.
Most whitening systems just address surface stains. KöR® is different. It uses a refrigerated, high-potency gel paired with custom-fitted trays to penetrate deep into the enamel, tackling discoloration that other methods can't reach. That includes tetracycline staining, fluorosis, and years of stubborn buildup that haven't responded to over-the-counter products or even previous professional treatments.
If you think a teeth cleaning is just scraping and polishing, Guided Biofilm Therapy will change your mind. GBT uses a disclosing agent to reveal hidden bacterial buildup, then removes it with a combination of gentle air polishing and warm water rather than traditional hand instruments. The result is a deeper, more thorough clean that reaches areas conventional methods often miss, including below the gumline.
Jaw pain, headaches, and clicking or locking joints are common, and finding a dentist trained to diagnose the root cause can be difficult. Dr. Grant and Dr. Sharlenne's advanced training at the Kois Center places a heavy emphasis on TMJ diagnosis, which means treatment starts with understanding why you're in pain, not just managing the symptoms.
Dental implants replace tooth roots and support restorations like crowns, bridges, and dentures to address any degree of tooth loss. Dental implants are considered the gold standard in tooth replacement, as they are the only solution that can stimulate the jawbone after tooth loss, preventing jawbone atrophy. With proper care, your implants can last for the rest of your life.
Hear From a Veneers Patient
“I truly can’t say enough good things about Dr. Grant Smith and his entire team. I was so excited about getting veneers, but honestly a little intimidated too, and Dr. Smith made the entire experience feel easy and reassuring from the very beginning. He is incredibly kind, patient, detail-oriented, and always made sure I felt cared for throughout the process. His bedside manner is truly unmatched.”
