About The Dental Loft

Same-day crowns, a spa-like office, and Dr. Heather Keeling's habit of giving honest second opinions set this Portland practice apart from typical dental visits.

The Dental Loft is a general dental practice that also offers Invisalign, traditional and clear braces, and clear aligners alongside its regular services. Reviews highlight a recently relocated office described as bright and spa-like, with same-day crown milling and modern technology used often. Dr. Heather Keeling, who took over the practice from a longtime retiring dentist, is noted for spending extended time with patients, offering candid second opinions rather than pushing unneeded work, and handling complex cases like TMJ. A notable number of reviewers mention transferring mid-treatment from other offices and finding the switch smooth.

Summary of 200 patient reviews, December 2020–August 2026, updated September 2026

Wonderful experience! I highly recommend The Dental Loft! The front desk staff is super friendly, and they always get me checked in quickly. My hygienist, Nikki, is really gentle yet extremely thorough, and she consistently checks in during my cleaning to make sure I’m comfortable. And let’s talk about Dr. Keeling! She is so kind, and she listens so well! Plus, she explains things very clearly and is also super understanding of what her patients want for results. My teeth look amazing!

I had a great experience at The Dental Loft. From the moment I arrived, the staff was welcoming, professional, and made me feel comfortable. Dr. Heather Keeling was thorough, knowledgeable, and took the time to explain everything clearly, making sure I understood my treatment options without feeling rushed. I really appreciated their gentle approach and attention to detail. My hygienist Shalyn was outstanding as well. They were friendly, gentle, and did an excellent job during my cleaning. They made the entire experience comfortable, answered all of my questions, and offered helpful tips for maintaining my oral health. I highly recommend The Dental Loft to anyone looking for a caring, professional dental team. Thank you for making every visit such a positive experience!

Had a cleaning and x-rays today. Very pleasant staff, as usual, and got me in on time. They have the ability to make a crown right in the office while you wait which avoids the temporary crown and waiting for an outside lab to make one. The best!!
