Out of the 5 teeth I had worked on by Dr. Hoaglin, one cracked after it was filled and needed to have a crown (from another dentist). The filling came out of one and had to be replaced (but they partially paid to have it fixed). And one is pretty sensitive (but probably simply from having a filling). The other two have been fine. He is a really nice guy. On the up side he was pretty gentle while fixing my teeth, and I did not have a lot of pain like I have in the past.
