I have been to ORA twice, once to have my wisdom teeth extracted and yesterday to have a molar extracted. Both procedures were done by Dr Koos. He is excellent! The first time I was put to sleep but the last time I was awake. I was a little worried about the last one but Dr. Koos explained what he was doing the entire time so it wasn’t bad at all! With both extractions I had minimal pain and no swelling. He and his staff are very good with explaining the aftercare and he calls to make sure you aren’t having any issues. I highly recommend Dr Koos.
