About Boston Smiles

Same-day and next-day urgent visits stand alongside on-time appointments, drawing in patients transferring mid-treatment from other providers.

Boston Smiles is a general dental practice that also offers Invisalign alongside routine care for adults and children. Reviews often mention quick scheduling, including next-day urgent visits and same-week openings, along with a low-wait experience on most visits, though a handful describe last-minute cancellations or long delays. Dr. Jahnsen is frequently described as gentle and thorough, taking time to walk through treatment options, and the office itself comes up often as clean, modern, and calming.

I've been really happy with Boston Smiles. The team is personal and professional, and they communicate clearly throughout each visit. I always feel comfortable during procedures, which makes a big difference. I also appreciated how transparent they were about costs upfront, no surprises on the bill. Highly recommend if you're looking for a dentist who genuinely cares about patients.

All the dentists are really nice and very thorough. I’ve had a lot of work done and it’s not completed yet but my teeth look great. They have definitely paid attention to detail. Great job.

If I could give zero I would. My 6 month check up consisted of a polish and flossing only. The floss was consistent of thick twine and some got stuck in my teeth. The 2 assistants that did "the cleaning" and "the dentist' were all rushed. The dentist came in, needed correction on who I was. She took the tool and literally lightly ran it over 3 upper teeth. Did not "poke" any as they do, nor measured my gums. (No x-rays were done so I feel a little more attention other than basic questions from the assistants that may or may not have been relayed is appropriate). She was in the room, no exaggeration, less than 3 minutes. So glad my insurance will pay her in full and who knows if there are any cavities or anything needing attention. Because asking if I have any concerns is the protocol. (Because we can always feel if something needs attention, right?) She advised I come back in 6 months. Why? If I don't have concerns and unless I want to get flossed with twine. No, absolutely not. It went so fast I did not catch "the dentist's name"name,. unfortunately.
