I certainly agree with Dr Singh’s comments. It sounds like your canine is of poor quality as one dentist advised you to keep the healthy premolars? Extraction treatment plans should answer these questions:
1) does the facial and lip profile need to be softened by changing the lip support via extractions? Would taking out teeth cause excessive space to undermine lip support that is currently good, causing an ageing look?
2) Are there alternative ways to create space other than extraction of teeth? Can this be safely achieved? Will it take forever?
3) if extractions are needed, can good quality teeth be preserved? Can teeth that have decay, large fillings, weirdly shaped, cracked teeth be taken out for space without sacrificing biomechanics and increasing treatment time unrealistically?
Do consider bringing up these points when you next discuss your treatment options with your dentist.
