Sedation dentistry costs in City Hall / Raffles Place
$150 – $800
Nitrous oxide (laughing gas) is cheapest ($150–250), oral sedation mid-range ($300–500), and IV sedation most expensive ($500–800) because it requires specialist administration.
Simple fillings under nitrous cost less; complex extractions or multiple procedures under deeper sedation cost more due to extended chair time and monitoring.
Clinics with pulse oximetry, blood pressure monitoring, and trained sedation nurses charge more but provide safer, verified care.
Dentist-administered oral/nitrous sedation is cheaper; IV sedation administered by an anaesthetist or IV-trained dentist costs significantly more.
| Option | Cost |
|---|---|
| Nitrous oxide (laughing gas) + local anaesthetic | $150–250 |
| Oral sedation (tablet + local anaesthetic) | $300–500 |
| IV sedation + local anaesthetic | $500–800 |

How sedation dentistry works: a step-by-step guide
- 1
Pre-sedation consultation and assessment
15–20 minutesYour dentist reviews your medical history, current medications, and anxiety level. Blood pressure and pulse are checked. If you're opting for IV sedation, an anaesthetist may assess you separately. This is your chance to be honest about your fears—the team is used to hearing them.
- 2
Sedation administration
5–30 minutes depending on sedation typeDepending on your chosen type: nitrous oxide is delivered via a nose mask (you smell and feel nothing but relaxation), oral sedation is a pill taken 20–30 minutes before treatment, or IV sedation is administered through a small needle in your arm. You'll be given clear instructions on what to expect.
- 3
Continuous monitoring during treatment
Duration of procedure (typically 30–120 minutes)A trained nurse or assistant monitors your oxygen levels, heart rate, and blood pressure throughout. A pulse oximeter is clipped to your finger, and a blood pressure cuff may be used. The dentist performs your planned procedure(s) while you remain calm or asleep.

Recovery and reversal (if needed)
15–30 minutes for full consciousnessAs the procedure ends, sedation begins to wear off. If IV sedation was used, a reversal agent may be given to help you wake up faster. You'll be kept in the recovery area until you're fully alert and able to communicate clearly.
- 5
Safe discharge with post-care instructions
Discharge is typically 30–60 minutes after sedation endsA responsible adult (family member or friend) must collect you if you had oral or IV sedation. You'll receive written aftercare instructions: avoid alcohol, heavy meals, and strenuous activity for 24 hours; rest at home. Most patients feel normal by the next day.
Who is a good candidate for sedation dentistry?
Good candidates
- Adults with moderate to severe dental anxiety or a documented phobia who've been avoiding the dentist for months or years
- Patients with a strong gag reflex that makes normal treatment impossible or extremely uncomfortable
- Anyone needing multiple procedures in one session (e.g. extractions + implant prep) who wants to complete treatment efficiently
- Individuals with special needs or medical conditions (autism spectrum, ADHD, intellectual disability) who benefit from a calmer, controlled environment
May need extra assessment
- Patients with uncontrolled high blood pressure, heart disease, or recent cardiac events—your dentist and an anaesthetist will assess safety before proceeding
- Pregnant women, especially in the first and third trimesters—discuss with your dentist; oral sedation may be avoided, but local anaesthetic and nitrous alone may be acceptable
- People taking multiple medications or with respiratory conditions (asthma, sleep apnoea)—a full medical review is essential to avoid complications
