Cooling before numbing for tooth nerve pain
Part of Mouth & dental clinical trials.
This study tests whether applying cold to your gum before a numbing injection helps the anesthetic work better for a severely painful lower front tooth. Researchers want to see if this simple cooling step reduces pain during the procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 60 years old
- You have severe pain (8 or higher on a pain scale) in a single lower front tooth due to an inflamed nerve
- You have not taken any pain medication in the 6 hours before your appointment
- You are in generally good health (no uncontrolled diabetes, thyroid problems, adrenal issues, or Raynaud's disease)
- You are not pregnant and have no known allergies to numbing medications
- The painful tooth has no infection around its root (confirmed by X-ray)

Other trials that look related to this one.
This trial compares two ways to numb a painful lower back molar. If you have a tooth infection that needs a root canal, you may receive one of two injection techniques to see which works better.
This trial tests whether a single injection of dexamethasone (a steroid) near the nerve of a painful lower molar can improve pain relief during a root canal. It's for people with severe tooth nerve pain who haven't taken pain meds recently.
This study compares two materials (MTA and Biodentine) used to treat a painful, infected nerve in a back tooth. Instead of a full root canal, the dentist will remove only the top part of the nerve and seal it. The goal is to see which material works better to save your tooth.
This study tests if taking a dose of diclofenac potassium, a common pain reliever, before a root canal reduces pain afterward. It may help people with severe tooth pain feel better during and after treatment.
This study tests whether applying cold (cryotherapy) to the gum and tooth before the numbing shot can make the anesthesia work better and reduce pain during a root canal for a severely inflamed tooth. If it works, the dentist's numbing may be more effective and you may feel less discomfort during the procedure.
This trial is testing two cold-therapy techniques applied directly to the tooth nerve to see which one better reduces pain during a root canal treatment. It aims to make the anesthesia work faster and more effectively, so you feel less discomfort during the procedure.
