Happy Gas Dentistry for Anxious Patients
Happy gas puts an end to dental anxiety
For many patients suffering from dental anxiety, dental phobias or fear of the dentist, happy gas (aka laughing gas) offers an ideal solution. Within minutes, your troubles can gently float away as you sink into a euphoric state of deep relaxation.

Regular trips to the dentist are essential. But some individuals put off necessary treatments or checkups due to anxiety or fears. Consequently, they can suffer further with poor dental health, requiring more treatment – and unnecessary expense. This is why happy gas/laughing gas is an ideal solution for many.
Happy gas works quickly and effectively to put you into a state of euphoria. It is designed to suppress sensors like touch and hearing, so is ideal for patients who hate tools in their mouth or the sounds of dental drills. Laughing gas also suppresses pain, as a happy gas dentist will tell you, these feelings will be greatly minimised.

How it works
Receiving happy gas is easy-breezy!
STEP 1
Pop on an inhaler
We’ll place a small nasal inhaler over your nose. The inhaler should feel completely comfortable to wear.
STEP 2
Take some deep, relaxing breaths
Take a few deep, relaxing breaths of the pleasant gas mixture.
STEP 3
Drift away
In less than a few minutes, you’ll slowly start to drift away. You’ll feel relaxed, comfortable, carefree and ‘happy’. Your dentist will wait until you are completely happy with your laughing gas, before they start work.
Depending on your treatment, your dentist may also administer a pain injection to numb the area completely.
STEP 4
Awaken to pure oxygen
After the procedure, we’ll turn off the gas and give you pure oxygen for a couple of minutes. Minutes later, you’ll come to, and soon feel completely normal.
FAQs about Happy Gas
Does happy gas put you to sleep?
Some people wonder, ‘does happy gas send me to sleep?’ That depends on the amount given. When happy gas is administered in larger amounts, would fall asleep. Your dentist will discuss with you the appropriate level of gas suitable for you. It’s about finding that sweet spot where you feel comfortable, but not unconscious.
