y is canine an unwanted tooth...even if its infected an giving u pain it can be treated with rct

Unwanted as in? Milk tooth?

Why do u want to extract a tooth like canine,one of the Most important tooth in oral cavity?

Depends on the location of the tooth and the c doctor.i f the tooth is erupted it will cost less.if  it is deep in the bone surgery is needeD and will cost more.

Depends on the difficulty level. Might cost you around 500 to 2000. And take about 15 to 20mins.

Why on earth do you want to get a canine removed at this age??? It is a tooth which is supposed to be most crucial for a good smile. Even if it is decayed, there are procedures like root canal treatment followed by post and core build up so that extraction can be avoided and the tooth can be given a long functional life again. The cost of the treatment varies from case to case depending upon the condition of the tooth and the experience of the dentist. Regards.
