Often called “happy gas” or “laughing gas,” nitrous oxide inhalation sedation is one of the gentlest and most flexible sedation methods available. It’s administered through a small, comfortable nose mask and takes effect within minutes, producing a warm, calm, floaty sensation that eases anxiety and reduces physical tension throughout the body.
You remain fully conscious and able to communicate with the team throughout your treatment, but the edge is completely taken off any nerves or discomfort. Local anaesthetic is still used to ensure the treatment site is numb; the sedation simply helps you feel relaxed and at ease while we work.
For patients with more significant anxiety, a stronger gag reflex, or those undergoing longer and more involved procedures, IV sedation offers a deeper level of relaxation. A carefully measured sedative medication is introduced through a small cannula, usually placed on the back of the hand or in the arm, and takes effect quickly.

We know that early dental experiences shape how a child feels about dental care for the rest of their life. A child who feels safe and supported at the dentist is far more likely to maintain good oral health habits and approach future appointments without fear.
At your initial consultation, we’ll take time to understand your concerns, discuss which form of sedation is most appropriate for you, and answer every question you have. Nothing happens without your full understanding and consent.
On the day of your sedation appointment, we’ll make sure the environment is calm and welcoming from the moment you arrive.
Dental anxiety can create a difficult cycle. Anxiety leads to avoidance, avoidance leads to problems going undetected, and untreated problems become more complex and more uncomfortable to treat, which in turn reinforces the anxiety. Sedation breaks that cycle.
Every story reflects our commitment to care, comfort and confidence.
View testimonialsIf you need dental treatment, whether for health or cosmetic reasons, but anxiety or fear is getting in the way, sedation dentistry is very likely to help.
This includes people with a fear of needles, those who struggle to cooperate during treatment due to highly sensitive or painful teeth, or anyone who has found local anaesthetics insufficient in the past.
Patients who have had a frightening or traumatic dental experience in the past often find that sedation gives them the confidence to return to the chair and move forward with their care.
It’s also beneficial for patients with a severe gag reflex, or those with medical conditions, such as Parkinson’s disease, that make it difficult to remain still during a procedure.
Inhalation sedation uses nitrous oxide, delivered through a small nose mask, to help anxious and dental-phobic patients feel calm and comfortable enough to undergo treatment.
It works by inducing a powerful sense of well-being, reducing inhibitions and nerves without putting you to sleep or leaving you feeling groggy afterwards.
The key difference is how each is administered. Inhalation sedation is delivered through a nose mask; no needles are involved.
IV (intravenous) sedation is administered via a small needle placed on the back of the hand or in the arm and produces a deeper level of relaxation.
Both are safe and effective; the right choice depends on your level of anxiety and the nature of your treatment.
Inhalation sedation is generally well-suited to patients with mild to moderate dental anxiety. If your anxiety is more severe, we are more likely to recommend IV sedation to ensure you’re sufficiently relaxed throughout your appointment.
We’ll always discuss which option is most appropriate for you at your consultation.
No. Inhalation sedation induces a warm, relaxed feeling of well-being and significantly reduces the nerves and tension you might normally experience.
Once the sedation has taken full effect, your dentist will administer a local anaesthetic to numb the treatment site so you won’t feel the procedure itself either.
Inhalation sedation is compatible with virtually any dental procedure we offer at Smile Society. Some of the most common include fillings, root canal therapy, and extractions, but it can be used alongside a wide range of both routine and more complex treatments.
Inhalation sedation reduces anxiety for the full duration of your procedure, helps you feel more relaxed throughout, and eliminates the need for any needles during administration.
It has minimal downtime and, unlike other forms of sedation, leaves no lingering grogginess or “hangover” sensation afterwards. It also helps to reduce the gag reflex, which many patients find makes treatment far more comfortable.
Yes, and we believe it can make a real difference to how children experience dental care, both now and in the future.
We understand that there can be significant barriers for younger patients when it comes to dental procedures, and inhalation sedation is an excellent way to put a child at ease while allowing them to remain fully awake and responsive throughout.
At Smile Society, our environment is calm and welcoming, and our team always works respectfully within a child’s limitations and boundaries.
We place real emphasis on using those early dental visits to build confidence and trust, because a positive experience at a young age shapes how a person feels about dental care for the rest of their life.
Because nitrous oxide is delivered through a nose mask, patients need to be comfortable breathing through their nose for the duration of the procedure.
Inhalation sedation may not be suitable if you are unable or unwilling to breathe through your nose, feel claustrophobic wearing a mask for more than a few minutes, have recently undergone facial surgery, or have a respiratory condition such as COPD.
If any of these apply, we’ll discuss alternative sedation options with you at your consultation.
