allli.livejournal.comok, i just had my initial visit at Gentle Dental in Porter Square, and was told i need a root canal. since this will apparently cost me $2000+, i think i'd like to make sure i need it and get a 2nd opinion. any recommendations for dentists in the cambridge area? i don't have dental insurance, so a cheap 1st visit is what i'm hoping for, but a reputable, honest, kind dentist too.
