Hypnosis has reasonable evidence for one specific job: easing anxiety while a dental procedure is happening, particularly oral surgery. For the longer-term problem of dental phobia, the fear that keeps people away from the dentist for years, the stronger evidence sits with cognitive behavioural therapy (CBT). Hypnotherapy can still be worth trying, as long as you know what it can and cannot be expected to do.
What the research says, in plain terms
A large 2024 review (Steenen and colleagues, Journal of Anxiety Disorders) pooled randomised trials on dental anxiety in adults. It found moderate-certainty evidence that hypnosis reduces anxiety during oral surgery, with a modest effect size. For dental phobia itself, the evidence, of low to moderate certainty, supported psychotherapy, and CBT in particular.
A 2022 systematic review and meta-analysis focused on hypnosis (Wolf and colleagues, Brain Sciences) reached a similar place. The trials used such different methods that only five could be combined, and their results were mixed: some showed a strong calming effect, others a small or slightly negative one. Across the 19 trials reviewed, CBT had the most evidence for reducing dental anxiety. The authors called hypnosis promising but said more consistent research is needed.
So hypnosis is a reasonable option to add for some people, especially around a procedure they dread. It is not a guaranteed fix, and responses vary a great deal from person to person.
What hypnosis involves, and what it does not
Clinical hypnosis is guided, focused attention combined with deep relaxation. It has nothing to do with stage shows. You stay aware of what is happening, you can speak and move, and you can stop at any time. Some people work with a trained hypnotherapist beforehand, some learn self-hypnosis to practise at home, and some listen to a recorded track through headphones during treatment.
Preparation often starts well before the appointment. Sessions may focus on the particular trigger, whether that is needles, the sound of the drill or the feeling of lying back without control, and on a technique you can use in the chair. On the day, the hypnotherapist or a recording may guide you into a relaxed state before treatment begins and keep talking you through it.
Hypnosis and sedation are not the same thing
Sedation uses medicine to make you more relaxed or drowsy and needs monitoring by the dental team. Hypnosis uses no medicine at all. The two are not interchangeable, and whether they could be used for the same visit is something to talk through with your dentist.
At Lumi Dental, the options for nervous patients include happy gas (relative analgesia, or nitrous oxide), inhaled pain relief, oral sedation and IV sedation. We do not provide general anaesthetic. Ask us about sedation options if hypnosis alone does not feel like enough.
Who tends to get the most from it
Hypnosis may suit people who respond well to relaxation techniques, are willing to prepare beforehand, and want to stay fully conscious. It can also appeal to people who have tried simple measures without enough relief but prefer not to use sedation for personal or medical reasons. For mild nerves, clear explanations and a sense of control are often enough on their own.
If fear has kept you away from the dentist for years, consider seeing a psychologist for CBT as well. That is where the evidence for treating dental phobia over the long term is strongest, and the skills carry over to future visits.
Building a plan that combines approaches
Most people do best with more than one tool. A useful starting point is simple: the dentist explains each step before doing it, and you agree on a signal, such as raising a hand, that means stop. From there, short, low-pressure visits can rebuild confidence gradually. A first appointment might be only a conversation and a look, with no treatment at all.
Hypnosis, CBT and sedation can then be added for the procedures that feel hardest. Our guide to adult dental anxiety covers the wider picture. If particular sounds are the problem, see our article on sound sensitivity and the dental drill, and many of the same adjustments appear in our pieces on autism-friendly dental visits and sensory needs at the dentist.
Common questions
Will I be asleep or unaware?
No. People under clinical hypnosis stay aware, can talk and can stop the process whenever they choose.
Can my dentist do the hypnosis?
Some dentists have training in hypnosis techniques; others suggest preparing with a qualified hypnotherapist. Ask before booking so everyone knows the plan.
Is hypnosis suitable for children?
Relaxation and imagery techniques are sometimes used with children. Whether hypnosis suits a particular child depends on age, temperament and what they fear, so talk it through with the dental team first.
What if it does not help enough?
That happens, and it does not mean treatment cannot go ahead comfortably. Gradual visits, CBT and sedation remain options, alone or together.
If fear has been keeping you away, the team at Lumi Dental can talk through what might help, at your pace. Free consults are available for nervous patients; see our current offers for details, or book a time to talk.
