I'd never had a root canal before today and what somewhat trepidatious about the prospect. Dr Koshiyama was a recommendation from another Endodontist located in Napa (the one my dentist referred me to), and therefore too far away for me to visit.
Dr Koshiyama and his staff were excellent in every respect. Not only did he spend plenty of time beforehand explaining the procedure and gathering every relevant detail, he also carefully answered all my questions to put me at ease.
I'd read that a root canal was not only painful, but lengthy, so I was not looking forward to 2 hours in the chair, plus a possible second session. While I'm sure every root canal situation is different, I was all done in about an hour and 15 minutes.
Dr Koshiyama was thorough (taking x-rays three times to make sure the job was done correctly), gentle (always telling me where we were in the procedure), and efficient. Yes, it blows to keep your mouth open for more than an hour, but if you sit still and suck it up, it's over much faster.
Did I mention it was completely painless? I was good and numb before he started, and his assistant provided a radio headset so I could focus on something else. I recommend tuning to a classical music station - it certainly helped me calm down and relax. Seriously, I didn't feel a thing.
I highly recommend Dr Koshiyama and his team. If I ever need another root canal, I'll be straight back in his dental chair. read more
