Next visit; Saw the junior specialist who had previously filled same tooth. He gave a thorough examination and determined that there wasn't enough of my broken tooth remaining to make a post and crown doable. Had it extracted for 700 baht. Must say, very rapid, zero discomfort and no pain when local anaesthetic wore off. Recommended to return in 2 to 3 months for implant; Korean for 37,000 or German for 40,000 baht. I will manage without!
