I had noticed bruising ("bluish hue") on my face when I came home after a filling appt. The filling was on an upper second premolar tooth. This looked very embarrassing for me especially when I go out in public. I emailed the office upset that this happened. I stated in email that I would go find another dentist. Is my dentist at fault here for giving me a faulty injection? I am thinking of filing a board complaint. Don't ever want to see that dentist again.
