You don’t need to settle for a smile that doesn’t reflect how vibrant and confident you truly are. At Keene Smiles, we offer versatile treatment options to suit every concern and comfort level. Explore our cosmetic services:
  • Teeth Whitening – Turn back the clock with professional whitening that safely lifts years of stains. Choose in-office speed or convenient take-home options for a luminous smile.
  • Dental Veneers – Custom-made porcelain veneers conceal chips, gaps, discoloration, and more. They’re a long-lasting way to reshape and refine your smile with minimal prep.
  • Tooth Bonding – In just one visit, bonding repairs small cracks, closes gaps, and evens out worn edges using a shade-matched composite resin. It’s affordable, painless, and instantly effective.
  • Smile Makeovers – No two smiles are the same. Our makeover plans combine services like whitening, veneers, or bonding into a cohesive, step-by-step transformation tailored just for you.
  • Gummy Smile Treatment – We use gentle contouring to create harmony between your teeth and gums, reducing excess gum tissue and revealing a fuller, more balanced smile.
  • Orthodontics – Discreet clear aligners straighten your teeth without the hassle of metal brackets. Perfect for adults and teens, they’re comfortable, removable, and easy to manage.
Each smile we enhance is treated with artistry, care, and intention—because you deserve results that look and feel like your best self. Let’s bring your dream smile to life.

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!

The folks at Keene Smiles are efficient and proficient. My appointment was on time and the technician made me comfortable while she took the x-rays and did the cleaning. Dr. Keene explained the condition of my teeth in a very understandable manner.
