### input:
I had a filling changed for right upper first molar, but in 2 weeks I was having intolerable headache, pain in ear, tongue, jaw and surrounding areas. The doc re-opened the filling and found pulpitis, said his drilling might have exposed pulp. I was prescribed anti-biotics for a week and he did root-canal. 3 canals were found and filled, on top of the filling he put cotton stuffing and then the temporary filling. He had already used up all of my insurance on the fillings, so said the permanent filling could be done in an year. Is it safe to wait for an year, I am not really sure if he did the sealing properly.

### output:

Hello, After pulpits and root canal therapy, there will be a period of healing required before the tooth feels better. The antibiotic should help to heal and reduce inflammation. Take some anti-inflammatory medication such as Tylenol or Motrin. Return to your dentist for a follow-up visit if it is not improving or feels worse. Do you hit the tooth hard when you bite? You may need the tooth adjusted to reduce stress. I recommend taking an X-ray. Consider getting an evaluation by an endodontist. This is a root canal specialist. I do not recommend restoring the tooth until it is comfortable. A hidden canal might exist or pretreatment may be necessary. I do not recommend leaving the tooth in a temporary filling for a year. You risk fracture, and it can continue to decay without causing pain. Plan to progress with a restoration. For back molars, I recommend a post and core with a crown. Sometimes, I place the post and core with plans to place the crown at a later time. Also, a temporary crown to prevent fracture, can be placed for a longer period of time to allow monitoring of the progression of healing with this tooth. Thank you for your inquiry.
