Painful tooth, had a root canal. Should I get a new crown?

Hi, I would like to ask for your help. Last summer I was supposed to get root canal done. My denstist told me he can do only one root, the other root he cant access. After ensuring me its not a problem he put a crown on and off I went. About a year later, this summer I went to Europe visit home and the tooth started to hurt. Xray showed its infected. The dentist had a really hard time to get to the bottom but she got it and then cemented the crown back. Now I got the pain back. So back to xray, oh it is infected again. We went to the best dentist in the city to get it treated, hopeing this will be the last time. But he wants to treat it and give me also a new crown. Do you think he is just trying to rip us off? Is there really a need for a new crown? Thank you for your answer.

Hello,
I am Dr.Neha Gupta (dentist) and am glad to address to your query here.

There are a number of possible causes of pain after the completion of a root canal. After a root canal is completed no living pulp tissue remains inside the tooth, but nerve endings remain in the ligaments that attach the tooth to the surrounding bone. These ligaments have nerve fiber associated with them that can feel pain. They are the source of any post root canal pain.

visit the dentist and get an IOPAR done and plan yor reatment according to that.

Take care and please keep me informed of your progress at healthcaremagic through my profile directly.

Hi,

Thanks for asking the query,

Pain in the root canal treated tooth can be because of imcompletely treated tooth, re-infection, food lodgement between the tooth and crown .

I would suggest you to get an x-ray done .
go for re-rct if required.
Get complete mouth scaling and polishing done.
Take antibiotic and analgesic for pain relief
Antibiotic and analgesic will give temporaray relief
Unless the tooth is devatilised , disinfected and sealed to the apex you may experience pain and infection.

Hope this helps out.

Regards..

Hello,
Thanks for posting your query,
This inflammation may be due to extruded sealer or 'over instrumentation during the endodontic procedure. Sometimes the root canal files go past the apical terminus and can either inject some debris periapically or just damage the ligaments. This inflammation usually resolves by itself given enough time.
If a root canal is completed, but an infection still is present around the periapical area then a retreatment may be indicated especially if significant time has gone by without a resolution of the infection.
I hope this information has been both informative and helpful

Hi
Welcome to HCM
I would suggest you to go for Re-RCT because there is some vital part still left in canal & because of which you are experiencing pain.At the same time, i think your previous crown can work & doesn't require a new crown if cutting is not done on your teeth.Rest all can be judged after clinical examination.

Take Care
Regards

hello & welcome
according to your history this is very clear that tooth had undergone RCT treatment several times.
usually in reRCT cases chances are not very bright.
as tooth is again infected & your dentist is saying that he can preserve this than may be he has noticed some untreated canal so you can go for treatment but always one thing should be kept in mind that chances are always relatively less.
thanks & take care

Hi
your tooth is infected and during rct procedure all roots are not properly disinfected thats why your pain sterted again.if any of the root is still infected and you want to save your tooth you should go again for rct procedure.and make sure your dentist completly remove your infection.when your infection removed properly then only your tooth is ready for crown.it will take some time to heal.after rct your tooth may need new crown because your tooth structure may be changed and crown may not be fittet on it.
all the best.

Dear friend.

Thanks for sharing your concern.

Root canal treatment is required in this case.

I would suggest you to visit an endodontist.(specialist for rct)

All the canals has to be properly located,cleaned aseptically,prepared and then filled.

Therefore visit your endodontist and get re rct done.

Remember,you will not have pain as now a days painless technique is followed.

Further a suitable new prosthetic crown has to be placed.

Hope it helps.

Thanks.

hello there and welcome ,

After going through your history i suggest you to get the root canal treatment done for your infected tooth from an endodontist, a specialist in root canal procedures.

Getting new crowns over the tooth will not solve the problem as the problem is not with the crown placement but is with the vital canal in the tooth that is left unexplored.

If its a molar tooth upper or lower , it will have 3 or sometimes 4 canals , they need to be explored , cleaned , shaped and filled till the apex , this procedures devitalises the tooth completely ans it seals the apex of the tooth from the surrounding tissues so there is no question of pain and infection to the tooth once the root canal is done properly. then you can go ahead for crown coverage over the tooth just to give mechanical strength to the tooth to withstand biting forces. Re exploring the canals and removing the infection will only subside your symptoms.

i hope this information helps you ,

take care.
