Steps for filling a tooth

You may have injured the nerve of the tooth with that great pain, so the treatment steps in our hospital are as follows

1.Open the pulp cavity: put in a cotton ball to open the drainage.

2. Usually two days later for follow-up. A nerve-killing drug is placed in the open medullary chamber and temporarily sealed. Usually formaldehyde cresol or camphor phenol is used.

3, two weeks after sealing, remove the temporary seal and medication, draw off the nerve that has been killed, clean the root canal system, do root canal preparation, root canal preparation, seal the sterilized medication, temporary seal. At this point your nerve has been completely inactivated, so you shouldn't feel any pain when the nerve is extracted. It may be a little uncomfortable to do the root canal preparation.

4, a week later, if the disinfection meets the requirements, you can carry out the root canal filling, at this time the root canal treatment is complete. Then it is time to repair the missing tooth and consider what type of restoration to take. If the requirements are not met, it will be necessary to re-sterilize, and then repeat the visit a week later, and so on until the sterilization requirements are met.

This is standard practice, so I'm not sure why your doctor told you to go in once a day. But I'm sure the second time you went in you put in what should have been a medicated cotton ball to kill the nerves.
