I agree with freedom2012. I had many tooth problem and i didn't have insurance too. I suffered a lot. My teeth are very sensitive and I do take care of them very well now. I go to dentist every 3 months, brush my tooth twice per day, floss and mouth wash every time. Also, you shouldn't be eating anything for 30 mins after mouth wash. I used to get tooth-ache every month but these days I don't have any teeth problem since 2/3 years. Prevention is better than cure my friends.
