I had my right canine surgically removed which was stuck under my incisors as my right canine is still my birth tooth so it didn't come out. So the surgery was big as they had to remove it and also protect the incisors. After surgery they stitched it and they removed half of the stitches after 10 days and half of them are still not removed. It's been 12 days now and i wanted to know if it's okay to keep stitches for this long.
