Can you tell me how much time does it take for your upper canine teeth to come in?

Cuspid Eruption: We can only tell you general time frames of eruption. However, this varies greatly. It's also important to check x-rays in order to make sure the upper canine teeth are coming in straight ; have enough room. Ask your own dentist to evaluate your particular situation with a clinical exam, orthodontic evaluation ; x-rays. http://www.ada.org/sections/publicresources/pdfs/chart_eruption_perm(2).pdf.
