What Is Sedation Dentistry?
Sedation dentistry uses safe, controlled sedatives to calm patients during dental work. Many people feel uneasy about visiting the dentist due to fear, discomfort, or past experiences. Our goal at Bayside Dental Discovery Bay is to transform that anxiety into relaxation with sedation dentistry, allowing you to get the care you need without worry.
Nitrous Oxide (Laughing Gas): Our Sedation Option
We provide nitrous oxide, commonly known as “laughing gas,” as a key part of our sedation dentistry services. This colorless, odorless gas is inhaled through a small mask and works by:
- Slowing Reaction Time: Creates a calm, euphoric sensation.
- Reducing Anxiety: Helps you relax before and during procedures.
- Managing Pain: Acts as a mild pain reliever for added comfort.
Laughing gas is a gentle sedative, perfect for patients of all ages. It takes effect quickly, and once the mask is removed, the effects wear off fast, letting you resume your day with no lingering drowsiness.
Why Choose Sedation Dentistry?
- Comfort: Feel at ease, even during longer treatments.
- Anxiety Relief: Ideal for nervous patients or those with dental phobias.
- Safety: Administered by trained professionals with precise control.
- Flexibility: Pairs with any procedure, from cleanings to root canals.
At Bayside Dental, sedation dentistry with laughing gas ensures a positive experience tailored to your comfort level.

Frequently Asked Questions
Is laughing gas safe, and who shouldn't have it?
Used with a dentist’s assessment and monitoring throughout, laughing gas (nitrous oxide) is a gentle, safe form of sedation; the dose can be adjusted to how you respond, and it wears off quickly once the mask is removed. Your dentist will check your medical history first. It’s generally not suitable during pregnancy (especially the first trimester), for people with severe breathing conditions (such as COPD, severe asthma or a blocked nose), or after recent middle-ear or eardrum surgery, so let your dentist know about any of these.
Will I be asleep with laughing gas?
No. Laughing gas gives light sedation: within a few minutes you feel calm and relaxed, but you stay awake and can talk to your dentist and follow instructions. It has a mild pain-relieving effect, and local anaesthetic is still used where the treatment needs it. If you want a break, agree on a signal with your dentist beforehand, such as raising your left hand.
Can I drive or go back to work after laughing gas?
The effects wear off soon after the gas is stopped. With laughing gas alone, most adults can drive or go back to work the same day: you breathe pure oxygen at the end, rest at the clinic for about 15–30 minutes, and leave once the team confirms your alertness is back to normal. If laughing gas is combined with an oral sedative or pain medication, you’ll need someone to drive you. Children should go home with a parent or guardian.
Can children have laughing gas at the dentist?
Yes. Laughing gas is used for both children and adults, and your dentist will assess whether it suits your child based on age and needs. For nervous children, the dentist also explains each step in simple terms so they can settle in gradually. See Kids Dentistry for more on children’s visits.
Are there other sedation options besides laughing gas?
Yes. Deeper sedation such as IV (intravenous) sedation is generally used for more complex procedures or severe dental anxiety. It’s given alongside local anaesthetic, with your heart rate, blood pressure, oxygen levels and breathing monitored throughout. You’ll usually need to avoid food and drink for at least 6–8 hours beforehand and have an adult take you home. Your dentist will assess whether it suits your health and treatment needs; for specific arrangements, please contact our North Plaza or Main Plaza clinic. Agreeing a stop signal with your dentist beforehand, bringing headphones with music, or deep breathing can also help you feel calmer.
How much does laughing gas sedation cost?
Based on the Prince Philip Dental Hospital (PPDH) private patient fee schedule, inhalation sedation (nitrous oxide) is about HK$5,000–$10,000 per hour. The schedule lists it as a separate item under paediatric dentistry, and it doesn’t include the dental treatment itself. The actual fee depends on how long it’s used and the treatment involved. For reference only; this is not our clinic’s actual pricing, and your fee is confirmed after an examination. See the full fee reference.
