Terrible. I would never go there again. He left a needle in my brothers tooth when he did a crown for him a few years back and missed up on a few fillings on my brothers teeth. Last week my brother had to pull three teeth out with a great Dr in Dallas because of Ahangarzadeh's bad work. He has also done fillings for me and it was so bad that the doctor in Dallas had to fix the work and he said I didn't need any fillings. I have also had a terrible experience when he pulled my wisdom tooth that I never went back again to pull the other ones with him.
