This design suggests the Catalina Mountains in southern Arizona which double as Native American arrowheads, giving the design a bit of heritage. Along the way, the client wanted to pursue an altered color scheme (2), changing the tan to a pastel yellow and use a brighter green. After a gestation period, they wanted to use the fonts with a different graphic idea altogether. An abstract smile. It was well received immediately.
It became clear that there was a definite desire to include a dental element in their logo. After numerous variations, the bottom design (3) is the final result. It was the winning design over 58 other global designers.
Ultimately, only two colors were used. All colors were chosen by the client. The client initially found it difficult to choose between the mountain/arrowhead theme and the smile/swoosh. I do favor the former, but it is most important to give the client what they want, not what you want.
