calcium in roots - toothache

[decidela]

Hello!
I had a filling done on my 26th tooth, and it started to hurt, so they did a root treatment. First the doctor found three roots and left anaesthetic there for a couple of days and then filled the roots with gutta percha.
I was still in pain. Then the doctor removed gutta percha and found one more root, which he cleaned out. As I had to leave the country the next day, he said he couldn't leave antiseptic in the roots again for a few weeks, so he filled them all with calcium.
The tooth was fine for a few days, but recently I went in pain again. It hurts if I chew on it, if I knock, and it doesn't ache much, but well enough to drive me mad. Is there a sign of some infection left or can the tooth start reacting to calcium? What can I do to reduce the pain? I am visiting my family in London and going back to my country in three weeks only...
Thank you! Anna.
PS. Please find attached the xray taken after the first root filling.

Thank you for your post.

It sounds like you may have had re-root canal stage 1 and the dentist has placed calcium hydroxide within the canals and with the plan for you to go back for re-root canal stage 2 on your return.

The problem is that stage 2 should normally follow stage 1 after a week or 10 days and if the tooth is left mid root canal treatment for a longer period than that, the temporary filling can leak and pain can arise again. You may need to see an emergency dentist now to have the canals cleaned again and redressed.
