Dental Implants

Dental implants are the closest you can get to the form and function of your natural teeth with a dental reconstruction. Not only do they look natural, but the implant also helps preserve your jawbone and gum tissue which is vital to your overall oral health. 

Benefits include:

  • Longevity of the restoration
  • Easy maintenance
  • Strength and durability

Our Happy Patients

Dr Phan and Dental Assistant Jane were really Pros from start to finish. Jane was absolutely hilarious and very attentive, while also totally professional. Her and Dr. Phan made a great team and were able to solve my complicated wisdom tooth situation and always kept me informed of every risk before proceeding. Thank you!

Dr Beckstead is amazing. I had partial bone loss around one of my teeth and three dentists think that I won't be able to keep it, but Dr Beckstead performed one surgery and saved my tooth. It has been over two years since the surgery and I have not had any more issues with that tooth.

I'm actually looking forward to my next prophylaxis. That's a teeth cleaning, and I never would have believed I'd say such a thing. I want to give a special shout out to Cindy, who did a fantastic job on my teeth AND gave me the tools and knowledge to nip gum disease in the bud. Have you ever heard of a Sulcabrush? I have one now, and it's awesome. Look it up.

Dr. Beckstead and his entire team are exceptional. They provided kind, informative and top-notch care every step of the way. My nerves were immediately calmed when I entered the office and I realized that I was in the caring and experienced care of true professionals. The procedure was flawless, the outcome was terrific and the entire process was pain-free (in every way!).
