Nitrous oxide sedation for children is a mild sedative gas, often called laughing gas, breathed through a small nasal mask. It helps a nervous child settle enough for treatment while staying awake and able to talk to us. A consultation with Dr Ope Sodeinde confirms whether it is the right choice for your child.
The gas takes effect within a few minutes and clears just as quickly once we stop it, so your child can return to their normal routine soon after the appointment.

Many children are frightened of the dentist, and a bad early experience can make every later visit harder. Nitrous oxide is the mildest option in our sedation dentistry in London range, and the one we use for children; oral sedation, IV sedation and general anaesthesia are adult or hospital options. We assess each child individually at a consultation.
Choosing sedation for a child is a decision for parents, and we make it with you. We assess first and give you an itemised quote before any fees are agreed. You get a sedation aftercare guide for the hours after treatment. For older patients facing surgery, we also provide sedation for wisdom teeth removal. Dr Sodeinde oversees the clinical standards of the practice.
Leave your number and we will call you back. Nothing is booked until you say so.
Nitrous oxide suits children who feel anxious, struggle to sit still, or gag easily. Because the effect is light and wears off quickly, they keep a sense of control throughout. Deeper options such as IV sedation and sedation for implant surgery are for adult patients. We confirm what your child needs at the consultation.
We meet your child, review their medical history and gauge how anxious they are. If a child needs more than nitrous oxide can offer, we discuss the alternatives with you; oral sedation is the next step for adults.
Your child breathes a mix of nitrous oxide and oxygen through a small nasal mask. Within a few minutes they feel calm and a little floaty, and the clinic feels less overwhelming.
We carry out the treatment while your child is settled, with local anaesthetic for the work itself. Nitrous oxide is often used for longer procedures and, in adults, for sedation for root canal. We monitor your child throughout.
We stop the gas and give oxygen for a few minutes. The effects clear quickly and your child is fully alert before leaving our Primrose Hill practice.
We check your child is comfortable and give you guidance for the rest of the day. Most children go back to their normal routine straight away.
Every case begins with a complete consultation, a pre-assessment and a medical history review. We monitor your child throughout the appointment. The practice is led by Dr Ope Sodeinde, GDC-registered specialist periodontist (GDC No. 104071). Sedation is administered by appropriately trained clinicians.
A parent or guardian stays for the appointment and takes your child home once they are fully alert.
We confirm the fee at the consultation, once we know what treatment your child needs, and itemise it alongside their children's dentistry care.
It starts working within a few minutes and is used for as long as the treatment lasts. We monitor your child throughout.
No. Your child simply breathes through a soft nasal mask. If a procedure needs more than nitrous oxide, we discuss general anaesthesia, which is arranged through a hospital pathway.
Only minutes after the gas is stopped. Your child recovers in the practice before leaving Primrose Hill.
