The treatment of broken tooth would depend on the level of dentistry facilities available in your region. Depending on the severity of injury, broken teeth can also be salvaged. One of the protocols involves doing a Root Canal Treatment (RCT) followed by either filling the tooth or placing a crown on it. It is possible that there is very little of your tooth remaining in which case it may have to be extracted. You must consult a dentist who can advise you after examining you.

Get yourself to a dentist. Broken, even chipped teeth can be weaker and prone to further damage or infection unless treated. Take painkillers if you're in pain.
