In brief: True Caker = 12 days

If it's a true canker sore, it should be healed without scarring at about 12 days.
However, since you also had trauma in that area (a bite), the wound may take longer to heal. In either case, however, the canker itself should be gone within about 12 days, while the bite may take longer.
