hello and welcome to HCM forum, Thank you for posting your query here, First of all, I would like you to know that tooth pain as described by you seems to be severe and very bothersome. Their could be one of the several reasons that is causing pain in your tooth, one of the most common ones is tooth decay. Until, a dentist examines your tooth clinically and radio graphically we cannot arrive at a diagnosis. For now, I will suggest you to see your dentist soon, The infection from tooth decay sometimes travels to the bone surrounding it causing swelling around it. Kindly do warm saline rinses 5-6 times/day, this will provide you temporary pain relief. If you have any further questions, feel free to write back to us. I hope I was able to provide you with an appropriate answer, I wish you good health, take care Dr. Anshika
