My mother's 4th number tooth from last in the upper right side was slightly broken in one corner few years back and light sensitivity was there. But day before yesterday while eating, some hard object was there in the food and the tooth was very badly hurt. She has taken antibiotic wymox tablet, hifenac p and voveran injection but nothing is helping and she is in severe pain. Please suggest what medicines could help and what could be done next. Thank you.
