Also known as ‘conscious sedation’ and ‘laughing gas’, happy gas helps to ease dental fear and anxiety (yay!). Happy gas sedation provides a mixture of nitrous oxide and oxygen. Nitrous oxide is a colourless, odourless gas that’s been used in dentistry for decades. It’s still a popular choice due to its safety, effectiveness, and speedy recovery time.
It’s really simple. You breathe in nitrous oxide (happy gas) through a mask that’s gently placed over your nose. The effects of nitrous oxide are quick, so you’ll feel calm and relaxed within minutes. Some people feel a little heavy. Some people have slightly tingly fingers. It can feel different for everyone, but you’re sure to feel relaxed. (Yes, you might even laugh a little!)

For example, if you have breathing problems or a blocked nose nitrous oxide may not be suitable. Also, it may not be suitable for very young children, as they can have trouble keeping the mask on.
