Happy gas or Nitrous oxide (N2O), is a widely used local sedation technique that effectively relaxes patients and create feelings of pleasure.

The gas is colorless and odorless and is safe for both adults and children. Administered under the supervision of your trained dentist Mandurah, happy gas quickly eases dental anxiety.

At platinum smile, we wish to make your dental visits more pleasant; we offer happy gas or nitrous oxide gas which is safe, trailed and tested; it is a way of reducing anxiety and nervousness during dental treatments.

Who uses happy gas?

Happy gas is safe for patients of all ages. It is a popular sedation technique for patients with dental anxiety.

Dental anxiety is the overall ill- feeling towards dental visits and procedures. It can range from mild anxiety to crippling fear.

Children who are having a hard time during their dental appointment may be assisted using the happy gas.

Happy gas or sedation is recommended for the following people:


Low pain tolerance


Bad gag reflex


Needing multiple or major dental work

Porcelain Veneers
Stained Or Discoloured Teeth

How Do I Know If I have dental anxiety?

Often, dental anxiety may not always manifest itself, and may only be observed when the person is already in the dentist.

Below are some of the behaviours a person with dental anxiety will show when they are already in the waiting area:


Frequent fidgeting with their hands


Sitting on the edge of their chair

Rapidly flicking through magazines


Changing sitting positions often




Sighing deeply or breathing rapidly


Talking loudly


Making negative comments about dentists and dentistry


Pacing or walking around the waiting room


Rapid head motions or startle reactions to office noises

If you are still unsure, we recommend taking this checklist developed by The University of Adelaide, Dental fear and anxiety: Information for Dental Practitioners

How is a happy gas administered?

Happy gas is safe, still to make avoid errors and for extra precaution, this will be administered under the guidance of your trained dentist Mandurah. The gas is given through a small nosepiece, controlled by your dentist Mandurah.

It is conscious sedation which means you will remain awake during the administration. You can still converse with your dentist even under sedation, and will not lose control.

Recovery is quick too and there are no after-effects.

Do children always need happy gas?

Despite their safety, happy gas is not always needed. If the child does not have trouble in a dental chair, then there is no need for a happy gas. Happy gas are only for assistance, to help calm you child, and improve his/her dental experience.

Frequently Asked Questions

Is happy gas just for children?

Happy gas is a popular sedation choice for patients of all ages. Anyone can enjoy the benefits of happy gas for their dental appointment.

How do I know which sedation method works best for me?

Your caring dentist Mandurah will help you decide the best option for you. The advantages and differences of each will be discussed to you prior to the procedure.

What is involved and what should I expect?

A comfortable nasal hood is placed over the nose and a mixture of happy gas and oxygen is breathed in.

The gas only needs a few minutes before you will start to experience a “floating” feeling. Once this desired state of relaxation has been achieved, your dental treatment will commence as normal. Local anesthetic injection will often still used to keep you more comfortable for the work.

Can I drive after the appointment?

Once your dental treatment is complete, the happy gas is turned off and only pure oxygen is delivered via the nasal mask. And within three to five minutes the “floating” feeling disappears and you return back to normal.

You will be able to drive yourself home on the day itself and carry on your daily routines as normal. Nausea and other after-effects are very rare.
