Sedation dentistry in London

Dental anxiety affects roughly one in four adults in the UK. If fear of the dentist has stopped you visiting for years, you’re not alone - and London has plenty of practices that specialise in treating nervous patients.

Most practices offering nervous patient care provide one or more of the following. Inhalation sedation using nitrous oxide, sometimes called laughing gas, helps you relax while staying fully conscious. IV sedation puts you into a deeply relaxed state where you’re unlikely to remember the procedure. General anaesthetic is available at some specialist clinics and hospitals for severe cases.

IV sedation in London typically costs £200-£500 on top of the treatment cost. Inhalation sedation is cheaper at £50-£150. Some practices include sedation in their treatment price for anxious patients. For a full breakdown of treatment costs, see our London dental cost guide.

If anxiety has kept you away from the dentist, call a practice and tell them. The good ones will take it seriously and talk you through your options before booking anything.
