I like #2....the smile, the color contrast, it is cute and fresh!

Hello! Here are some hints for getting the most out of your contest as it progresses:

~~ Rank designs daily -- this will encourage participation.
~~ Rank a variety of designs to get a variety of entries.
~~ Ranking gets your contest noticed! Unless your contest is Private, 1st place entries are posted to the portfolio page: https://logotournament.com/portfolio
~~ Leave private feedback by clicking on a design. Feedback will be made public upon contest completion
~~ The more feedback you provide, the better results you will see.
~~ Designers are not offended by "Not Interested".
~~ Over-use of "Not Interested" discourages participation.
~~ Designers earn points for designs ranked 1st - 10th. We like to earn points.
~~ After your contest closes it will enter Judging phase. You can re-rank designs in Judging.
~~ While in Judging, the designer ranked in first place can submit revisions

I like the use of orange as contrast. I ranked the one in particular #1 as it is young, 90% of my clientele....has a smile and smile like swoosh.....

I like a bit of abstract, no a big fan of the tooth...too literal and also doesn't say orthodontist, says dentist.
