I like the clean look here and the subtle implant reference, but like my previous comment don't want "Columbia" to overwhelm the focus of the business.... Dentures and dentistry.
can I see one that says only "Columbia Dental"? No implant reference or subtitle? Also if chosen are there modifications available after the contest ends?
The feedback I'm getting is to not no the implant tooth like you have (makes people think of drilling). Do you have another tooth graphic we could try?
