Do ALL 'double' teeth have two root canals? ?
I understand that 'double' teeth can have different patterns of root canals, e.g, '11' pattern, 'Y' pattern, 'H' pattern, and 'inverted Y' pattern, but do ALL doubles have two?
The tooth in question is the first double/premolar on the left top (starting from the front).
The reason I ask is that I had a route canal treatment some years ago, and recently a further problem. My dentist 'expressed' surprise at how rare two root canals were in this tooth, or perhaps some teeth.
I subsequently went to another dentist who advised that this particular tooth ALWAYS has two canals.
It may be a case of my dentist covering up for a lack of knowledge or poor work first time round by not treating both.
Further comment would be welcome.
