Hi,

Thanks for posting your query.

As you said,the pain associated with root canal treated tooth is due to its re-infection.

The tooth has to be either treated with re-rct or extracted.
If you are not willing again of rct,it has to be extracted and replaced with fixed or removable prosthesis.
Take analgesics-antibiotics as per dentist's prescription.
Maintain good oral hygiene.
Avoid hot/spicy /solid foods.
Hope this helps.

Hi,

Thanks for asking the query,

Pain after root canal treatment can be because of re-infection of the tooth .
It can also be because of presence of high points , or due to food lodgement between the tooth and cap (if the tooth is capped) leading to gingival inflammation and pocket formation .

You need to visit the dentist get checkup done.
&Take x-ray of the tooth , depending on which type of treatment will be decided.

Get complete mouth scaling and polishing done .
Take antibiotic & analgesic course .
Use 0.2% of chlorhexidine mouthwash gargles thrice daily.

Hope this helps out .

Regards....

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

If the pain after root canal is intense, this could be a sign of complications and possibly of a root canal failure.

The normal post root canal pain can be relieved by taking an over-the-counter pain reliever, usually an anti-inflammatory medicine like Ibuprofen. Sometimes an antibiotic is also prescribed to minimize the risk of a new infection.

In case of a failed root canal pain, a re-treatment and possibly an apicoectomy are needed in order to save the tooth. If neither proves to be successful a tooth extraction is necessary. A stronger prescription pain medicine may be needed for post root canal pain relief until the tooth is re-treated or extracted.
