My tooth cracked a month after getting it filled by him. The other tooth feels like it's going to break but hasn't yet. I went to another dentist to fix my tooth and had to get a $400 crown that he not surprisingly won't reimburse me for.
According to the new dentist, the tooth should've been crowned in the first place because there wasn't enough of my tooth to support a filling; there was still decay in my tooth that Dr. Dena didn't properly clean out; and the other tooth he filled was underfilled and would most likely break because there's not enough of my tooth left to support a filling.
