Services
Dental Implants
Dental implants are titanium posts surgically placed into the jawbone to replace missing teeth. They provide a durable, natural-looking solution that preserves jawbone health and facial structure. At Cornerstone Dentistry, we use advanced 3-D imaging and X-Nav technology to ensure precise placement, offering long-term results that mimic natural teeth in function and aesthetics.
Smile Makeovers
Smile makeovers combine multiple cosmetic procedures to address issues like discoloration, chips, or gaps. We create personalized treatment plans using porcelain veneers, crowns, and whitening to achieve balanced, aesthetically pleasing results. Our process includes digital smile design and provisional mock-ups to ensure patient satisfaction before finalizing treatments.
Sleep Apnea Treatment
We offer custom oral appliances like the EMA and Herbst to treat sleep apnea by repositioning the jaw and preventing airway obstruction. These non-invasive solutions improve breathing and sleep quality, reducing risks associated with untreated apnea. Follow-up appointments ensure optimal fit and effectiveness for long-term relief.
Emergency Dentistry
Our practice provides same-day emergency appointments for toothaches, trauma, or broken restorations. Dr. Thomas prioritizes pain relief and stabilization, offering treatments like root canals, temporary restorations, or extractions. We also guide patients through self-care steps to minimize complications before their visit.
Metal-Free Dentistry
Metal-free options include porcelain crowns, bridges, and composite fillings that eliminate allergy risks and enhance aesthetics. Materials like e.max and zirconia offer durability and translucency similar to natural teeth. This approach ensures both functional longevity and a seamless, natural appearance for restorations.

How do I care for porcelain veneers?
Brush twice daily with non-abrasive paste, floss regularly, and avoid biting hard objects. Attend routine cleanings to maintain veneer longevity and aesthetics.
