I had my teeth cleaned,several fillings and a crown.Dr. Yokoyama left most of the cleaning work to his assistant.
He did 7 fillings for me and it was the most horrendous dental job ever, their edges were sharp, unpolished, uneven so they were irritating my tongue and gums.The next dentist had to do repolished several so that they are less irritating until I can have them redone.Actually since then,4 months ago 2 of the fillings fell off.
There was a gap between the edge of the gum and the crown so I had a dark long black line. I requested to have the work redone, he was extremely rude and said that it was not his fault or the mold's but its my tooth that the crown did not fit (it was the most unprofessional excuse for bad sloppy work I have ever heard)
When he finally agreed to have the work redone, to remove the 1st crown he filled down my original tooth so much and couldn't do the right anchoring,my temporary crown fell off 3 times.
At that stage I knew that I will end up with very bad job no matter what.
I had my insurance recover the money they paid him, for me to have the work done somewhere else.
What work I had done by him were badly done,very carelessly, he was very dismissive and unprofessional.
Please stay away!
