Experience the Long-Term Benefits of Implant Dentistry

Dental implants function as artificial tooth roots, providing a strong foundation for replacement teeth. By integrating with the jawbone, implants help prevent bone loss, maintain facial structure, and restore comfortable chewing ability. Many patients choose implants because they feel secure, look natural, and support long-term oral health. Keene Smiles provides a wide range of implant solutions to meet your needs:
  • Single Implant With a Crown – A long-lasting solution that replaces one missing tooth while maintaining proper spacing and bite alignment.
  • Implant Bridge – A stable restoration for multiple missing teeth that restores chewing strength without relying on surrounding natural teeth.
  • Same-Day Smile – A streamlined option for qualifying patients that allows implant-supported teeth to be placed quickly, minimizing downtime and restoring confidence sooner.
  • Implant-Supported Dentures – A secure alternative to traditional dentures that improves comfort, stability, and chewing function.
  • Implant-Retained Dentures – A removable yet firmly anchored solution that offers enhanced control and confidence throughout the day.
  • Full-Mouth Reconstruction – A comprehensive treatment plan that rebuilds your entire smile using implant-supported restorations to improve function, appearance, and overall oral health.

For decades, I had a trusted dental office with the most amazing hygienist. Well, the dentist, I trusted and the hygienist, both retired and the rest of that clinic I used to go to doesn't cut the mustard for me.

Quynh smiles feels like my new dental office. although I have only gotten a crown placed and one cleaning, I can say that the work is up to par with my current needs.

The office staff is professional, kind, courteous, knowledgeable, and responsive. Dr. Keene himself has great skill and for anyone needing a crown this is your guy. ONE STOP SHOP, he has the lab right there! For those of you who don't know what this means, it means that you leave with your permanent crown instead of the usual, 2 to 4 week wait with a temporary crown which often times falls out or has complication before the permanent crown gets sent back to your dentist.

Overall highly recommend this place.

My visit was scheduled to replace a crown. Although I was very nervous about the work that would be performed, the staff made me comfortable and the procedure was as pain-free as can be under the circumstances. Dr. Keene explained every step of the process. The technology he uses to make the same day crown is simply amazing. So happy I found his practice!

My visit was a quick and thorough tooth cleaning. I hadn't been Keene Smiles for some time because of the pandemic. I'm glad I went.
p.s—Kristin, the hygienist, was great!
