Does having a tooth pulled invalidate fasting?

Dear Brother / Sister,

If no liquid like water and blood goes to your stomach, fasting is not invalidated but if some liquid goes to your stomach, fasting is invalidated. If an injection is given while filling the tooth, it does not invalidate fasting.

Whether an injection invalidates fasting or not depends on why it is used. Injections are given for various reasons like relieving the pain, treating, increasing the resistance of the body and giving food. The injections that are not regarded as food and giving pleasure do not invalidate fasting since they do not mean eating and drinking. However, injections that give food and/or pleasure invalidate fasting. The same decree is valid for the blood or serum given to a patient.
