Herbal medicine for root canal retreatment pain relief
Treatments studied
Part of Pain clinical trials.
This trial tests whether a natural herbal medicine placed inside a tooth during retreatment (a procedure to fix a previously treated tooth) reduces pain and complications after treatment. You may qualify if you have a tooth with failed root canal treatment and a small infection around the root tip.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Had a root canal treatment before that didn't work (only one-rooted tooth)
- Small infection visible around the tooth root tip (1–2 mm in size)
- Tooth has fully formed roots with no signs of breaking down
- Not currently pregnant
- Not taking antibiotics or pain medications right now
- No facial swelling or loose/severely recessed teeth

This trial tests whether a special cooling treatment (cryotherapy) can reduce pain right after a root canal for a badly infected lower premolar. If you are healthy and not on painkillers, this may help you feel better faster.
This study tests if a special bioceramic medicine placed inside the tooth after root canal treatment can reduce pain and sudden flare-ups in people with controlled type 2 diabetes who have an infected single-rooted tooth with a small abscess at the tip.
This trial tests whether two new dental rinses, used with special activation methods, can reduce pain and complications after treating teeth with severe pulpitis (tooth nerve inflammation). It may help people with multiple-root teeth who need root canal treatment.
This study tests two different ways of cleaning and treating a tooth that had a root canal treatment before. Researchers want to see which method causes less pain after the procedure.
This study tests whether cold therapy (cryotherapy) can reduce pain after re-treating a root canal infection. It aims to see if this treatment changes certain natural chemicals in the body (PGE2 and NGF) that are linked to pain.
This study compares two types of medications placed inside a tooth after root canal treatment to see which one reduces pain better. You'll be asked about your pain levels after treatment, and researchers will measure a pain-related substance in your saliva.
