Had root canal done. Temporary filling fell out and is painful. Cause and cure?

Two weeks ago I had a root canal on my back molar because a deep filling was causing pain. Today, I bit down on a chewy cookie and the temporary filling fell out, along with some cotton. It instantly became very painful. I can t get to the dentist till tomorrow. I thought that the tooth couldn t cause pain anymore because there are no nerves in it? What s going on?

Thanks for writing in.
As you provided the detail,it seems that root canal is incomplete and your dentist had given you instructions not to chew hard objects from that side,which you did not follow properly so your temporary filling came out.

Now i will suggest you for pain you can take pain killer,and do not chew and do not have food from this side till your treatment will get complete.

Nothing to get worried.
Take Care.

hi and welcome ,

After reading your history i can say Root canal treatment for your tooth is not completed .

I suspect it is your second sitting , where your dentist has put a cotton ball filled with a pain relief in the tooth cavity followed by a loose temporary filling.

As the nerve tissue is present in the tooth, exposure of the cavity to oral environment causes pain and sensitivity.

you need to complete the root canal treatment , at the end of which the tooth is completely devitalised and disinfected , and restored with a permanent fillling.

consult your dentist and talk to him about this , meantime place a small cotton ball in the cavity to prevent infection.

i hope this helps,

take care.

Thanks for sharing your concern with us
If there is pain present then defenetely there is pulp and your RCT procedure has not been completed yet.
RCT is a procedure of minimum 4-5 settings.
follow the antibiotic as per prescription and meanwhile you can do warm saline rinses
visit the dentist and get your tooth devitalize
You can contact me again directly through my profile.

Welcome to HCM
I would like to tell you that your RCT is not complete & you have been given closed dressing.
Temporary filling was given so that food shouldn't get entrapped but your dentist might have told you not to chew any thing from that side because it will cause pressure pain.
Moreover tooth is weak till RCT is not completed so avoid giving any pressure.
Now you can take Pain-killer for relief but avoid doing it again.
Also visit your dentist for completion of RCT.

Take Care

dear friend.

thanks for sharing your concern.

i guess your root canal treatement is incomplete. is it so?

root canal treatment is done in three steps like initially cleaning and shaping of canal,then obturating it with guttapercha and then finally sealing it with suitable restorative material.

after which the tooth is crowned to prevent it from fracture due to brittleness with prosthetic crown.

also i suspect canal cleaning and shaping is not sufficient because of which you are experiencing pain.(infection)

i would suggest to revisit your dentist and get an xray done to see if any periapical pathology has developed.

re entering the canal and aseptic canal preparation would help.

be sure after RCT your tooth will be painless

Thanks for posting your query.

Is the root-canal treatment for the molar tooth completed or treatment has just initiated?

Since the treated tooth is producing pain,infected vital pulp is remaining within the pulp causing inflammation and pain.

Meanwhile you can keep cotton within the cavity to prevent food lodgement.

please do visit the dentist and get the infected pulp removed and get the cavity filled.

ANtibiotics and analgesics has to be administered as per dentist'S PRESCRIPTION.

Thanks for asking the query,

I suppose that your root canal treatment is not completed , your dentist has placed an medication in a cotton ball over which a temporary filling was placed. As you chewed something hard from that side temporary filling came out .

pain is present as the treatment is not completed . take tab dolonex three times a day for three days .

You need to complete the root canal treatment consult the dentist and talk about this.

Thanks for the query
Temporary fillings are just that; they are not meant to last. They usually fall out, fracture, or wear out within 1 month. Be sure to contact your dentist to have your temporary filling replaced with a permanent one. If you don't, your tooth could become infected or you could have other complications.
