Dental Hygienist option is a very good option. However, it will take about 2 years to complete, and that's the same amount of time it takes you can be a DDS. I understand kids and family are a priority, however, if you all make a sacrifice for 2 years to let her complete her degree, it will definitely be worth it later (DDS start at $100,000/year, which is ridiculously good.)

Start applying now though! Deadlines come around December/January. Go to that web site that was mentioned above to inquire more about that.
