Key takeaways
- IV conscious sedation at a UK private practice costs £200–£600 on top of the dental treatment fee.

- NHS sedation is free for eligible patients — ask your dentist for a referral to a dental phobia service.

Dental anxiety affects an estimated 1 in 4 UK adults, and around 12% have severe enough phobia to avoid the dentist entirely. Sedation dentistry makes it possible to complete complex or multiple treatments in a single appointment while remaining calm and comfortable throughout.
Types of dental sedation and their costs
1. Inhalation sedation (nitrous oxide / "happy gas")
Nitrous oxide is inhaled through a small nosepiece. It reduces anxiety within minutes, raises the pain threshold slightly, and wears off within 5–10 minutes of removing the mask — allowing you to drive home.
| Location | Cost per appointment |
|---|---|
| UK average | £50–£150 |
| London | £80–£180 |
Best for: mild to moderate anxiety, children, short procedures.
2. Oral sedation (prescribed tablets)
Benzodiazepines (commonly temazepam or diazepam) taken 1 hour before the appointment produce a calm, drowsy state. You will need someone to drive you. Less predictable than IV sedation.
| Location | Cost |
|---|---|
| UK average | £20–£80 (prescription + admin fee) |
Best for: moderate anxiety where IV is not available; a step up from nitrous oxide.
3. IV conscious sedation
A benzodiazepine (usually midazolam) is administered via a small cannula. Within seconds you enter a deeply relaxed state where you can still breathe independently and respond to simple instructions but will have little or no memory of the treatment. You need a responsible adult to accompany you home and must not drive for 24 hours.
| Location | Sedation add-on cost (excluding treatment) |
|---|---|
| UK average | £200–£600 |
| London | £350–£700 |
Best for: moderate to severe anxiety, multiple or complex procedures, patients with strong gag reflex.
4. General anaesthetic (GA)
GA is only used for dentistry when IV sedation is insufficient — for example, very young children, patients with profound learning disabilities or those undergoing major oral surgery. Dental GA is carried out in a hospital or regulated clinic setting with an anaesthetist present.
| Setting | Cost |
|---|---|
| NHS hospital (eligible patients) | Free |
| Private hospital day-case | £800–£2,000 (anaesthetist + theatre, excluding dental fees) |
NHS dental sedation
The NHS provides free sedation to patients with a genuine dental phobia or clinical need through Community Dental Services and salaried dental practices. Your GP or dentist can refer you. Waiting times vary by area (typically 2–6 months). NHS sedation services are funded by integrated care boards and vary in what they offer — some provide IV sedation, others only nitrous oxide.
Which type of sedation should I choose?
- Mild anxiety: Nitrous oxide (£50–£150) is safe, fast-acting and low-cost.
- Moderate anxiety: IV sedation (£200–£600) produces a more profound effect with memory impairment — most patients find it transformative.
- Complex needs or very young children: GA under specialist referral.

Frequently Asked Questions
How much does IV sedation at the dentist cost in the UK?
IV conscious sedation costs £200–£600 as an add-on to your dental treatment. The dental work itself is priced separately. In London, expect £350–£700 for sedation alone.
Can I get dental sedation on the NHS?
Yes. The NHS provides sedation for patients with genuine dental phobia or complex needs through specialist referral services. Ask your dentist or GP for a referral to a Community Dental Service or salaried dental service with sedation facilities.
What is the difference between IV sedation and general anaesthetic?
With IV sedation you remain conscious but deeply relaxed — you can breathe independently and respond if asked. With general anaesthetic you are fully unconscious and breathing is assisted. GA carries more risk and is reserved for very complex cases or patients unable to cooperate with sedation.
Is happy gas (nitrous oxide) effective for dental anxiety?
Nitrous oxide (inhalation sedation) reduces anxiety and raises the pain threshold but keeps you fully conscious. It is very safe, wears off within minutes, and lets you drive yourself home. It costs £50–£150 per appointment, making it the most affordable form of dental sedation.
