It generally takes about two weeks to heal from a smashed toe. Because the toe is far from the heart, the blood supply is relatively poor, so healing is relatively slow when there is trauma to the toe or a wound on the toe. If the smashed area is under the toe nail, the healing time may be even later. This is because if there is bruising or a hematoma under the nail, it is often absorbed slowly and affects the nail bed, which means that the blood supply to the nail is affected. If the toenail has a hematoma and is large, it usually takes more than a month for the toenail to slowly change, that is, to recede and grow a new toenail, and then it will heal completely.
