Root canal. Dr Lew is a nice guy, does great work, BUT is kind of slow - meaning you will return for extra work as he ignores other issues unless you ask. I didn't at first - I figured HE IS the dentist, so he would fix the problems, but that wasn't the case. He fixed my urgent problems and the other work was just ignored until they too became urgent. I recommend him, absolutely, BUT make sure you TALK to him about ALL issues and make your appointments way in advance as he is booked solid. He has a really sweet, caring, dental assistant who handles cleanings and such - she is awesome.
