What is the ruling on blood coming from a wisdom tooth after waking up from sleep, which often continues until breakfast or stops after two hours with difficulty in expelling it, given that its treatment will not be possible for another three months?

Intentionally swallowing blood is forbidden and invalidates the fast. However, if blood reaches the throat unintentionally, it does not break the fast, and the fasting person must spit out the blood and not swallow it, to the best of their ability. It is recommended to continue with the treatment.
