Personalized Cosmetic Dentistry for a Smile That Feels Like You

Your smile should enhance your daily life—not hold you back. With today’s advanced cosmetic options, you can make meaningful improvements with minimal disruption to your routine. We offer a wide range of cosmetic services:
  • Teeth Whitening – Our in-office and take-home whitening treatments lift years of stains from coffee, wine, smoking, and age. You’ll see visible results quickly, safely, and without the sensitivity often caused by drugstore options.
  • Dental Veneers – These ultra-thin porcelain shells conceal chips, cracks, gaps, and stubborn discoloration. Veneers offer a long-lasting transformation with a smooth, flawless finish that still looks like “you.”
  • Tooth Bonding – A quick and affordable option for fixing minor flaws, bonding uses tooth-colored resin to repair chips, reshape edges, and smooth uneven enamel—all in one visit.
  • Smile Makeovers – Want a comprehensive approach? Smile makeovers combine several treatments tailored to your smile goals. Whether it’s a few touch-ups or a total overhaul, we guide you every step of the way.
  • Gummy Smile Treatment – If too much gum tissue hides your teeth, we use gentle contouring techniques to reveal a more proportionate, attractive smile. It’s a small change that makes a big impact.
  • Orthodontics – Straighten your teeth the discreet way with clear aligners. This modern alternative to braces helps correct crowding, gaps, and bite issues—without the hassle of metal hardware.
No matter which services you choose, our goal is always the same: a smile that makes you feel more like yourself. Your dream smile is closer than you think. Call Keene Smiles at 720-599-4479 to schedule your personalized consultation with a cosmetic dentist in Gunbarrel, CO who listens, cares, and delivers results. You can also request an appointment online.

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.
