Hypnosis before surgery and dental work: what recent reviews found

Two systematic reviews point to less anxiety and some pain relief, with clear exceptions.

A July 2026 review of hypnosis in anesthesia

Researchers searched four major databases for randomized trials of hypnosis in anesthesia. They found 19 trials with 3,699 patients, covering obstetrics, pediatrics and dentistry.[1]

  • Children and dental patients: hypnosis was linked to significantly lower anxiety before and during procedures, and partly reduced pain afterward.
  • Childbirth: hypnosis had no benefit on pain.

The authors note the number of high-quality studies is small, but conclude hypnosis could be a helpful addition in specific areas of anesthesia.[1]

A 2025 meta-analysis of invasive procedures

A separate 2025 review pooled 20 randomized trials with 1,250 patients having invasive medical procedures, comparing hypnosis with standard care.[2]

Hypnosis vs standard care during invasive procedures

Standardized mean differences. Negative values favor hypnosis; 0 means no difference.

Anxiety: -0.43 SMD (95% confidence interval -0.58 to -0.28). Pain: -0.35 SMD (95% confidence interval -0.5 to -0.2). Dots are pooled effects; lines are 95% confidence intervals. Effects of this size are usually called small to moderate. Neither interval crosses zero.-0.8-0.6-0.4-0.200.2Anxiety-0.43 SMDPain-0.35 SMD

Hypnosis reduced both anxiety and pain by a small-to-moderate amount. Heart rate and blood pressure were also lower, and adverse effects were minimal. Hypnosis combined with virtual reality, and approaches tailored to high-anxiety procedures, did best.[2]

If you have a procedure coming up

  • Ask your care team whether they offer hypnosis, a recorded session, or VR hypnosis. Some hospitals and dental practices do.
  • Use it alongside anesthesia and pain relief, never instead of them. Tell your anesthesia team if you plan to use a recording.
  • If you’re anxious about dental work or a procedure, calming practice beforehand is low-risk and fits what these reviews found.

Hypnova was not studied in these reviews. For how hypnosis compared on procedure pain versus long-term pain in another recent review, see hypnosis for acute vs chronic pain.
