Cleanings

 

Preventive care is the foundation of a lifelong healthy smile. Routine professional teeth cleanings can remove plaque, tartar, and bacteria that daily brushing can't reach, helping to prevent cavities, gum disease, and bad breath. Dr. Simkins and his team provide thorough yet gentle cleanings to ensure your teeth and gums stay strong for years to come.

Porcelain Veneers

 

If you dream of a flawless, radiant smile, veneers offer an elegant solution. These ultra-thin porcelain shells are bonded to the front of your teeth to correct discoloration, chips, gaps, and misalignment. Dr. Simkins's expertise ensures each veneer is custom-designed to complement your natural features, creating a look that is both stunning and natural-looking.

​Healthy Gums, Healthy Smile

 

Healthy gums are the foundation of strong teeth, and Dr. Reyes specialize in treating gum disease, recession, and infections to prevent further damage. Using advanced laser therapy, deep cleanings, and gum grafting, they offer effective, minimally invasive treatments for every stage of periodontal disease. Whether you need preventive care or surgical intervention, their expertise helps maintain healthy gums and strong teeth to protect your smile.

Dental Implants

 

Missing teeth can affect more than just your smile - they can impact your ability to eat, speak, and feel confident. Dental implants offer a permanent, natural-looking solution to restore both function and aesthetics. Whether replacing a single tooth or a full set, implants provide the stability and durability of real teeth, allowing you to eat, smile, and live without worry.

What Patient's Say

"I am very terrified of dentist just from bad experience. I rarely ever write a review, whether its not enough time or simply because for some reason or another I did not experience the WOW factor. Well coming to this office I definitely experienced the WOW factor and how rare is that at a dentist office. From the very first visit, I was treated with so much care and high regard to be sure I was comfortable...as I mentioned I was completely terrified. Where do you know, that you can actually laugh during a root canal and smile after having one done, feeling like that was GREAT!!! The staff that I have met so far are just phenomenal. There is just not enough thank you's and praises that I can give the entire team.  So happy with my new found dentist!"
