How much time does it take for your upper canine teeth to come in?

Permanent teeth: The permanent teeth usually take a couple of months to grow in but upper canines have the longest way to go which means that they take a bit longer. In case there is not enough space for them or the tissue around them has changed the upper canines can be retained in the bone. This condition is called "impacted canines" and can be treated with a combination of surgical and ortho techniques.
