Seriously? Electric shocks? Last time I went to a dentist she did an xray of the tooth that hurt me. Then she showed me the high resolution photo on the computer screen where I could clearly see what looked like a "bubble of something" right beneath one of the roots. This I was told is why I needed root canal treatment. The dentist used handheld xray machine.
