A Better Smile Dental Centres offer three different types of sedation alternatives for your dentistry procedures. You could be confident your next visit to the dentist will be relaxed and pain free.

Happy Gas

This is lightest type of sedation. There are several ways to sedate a patient that result in anxiolysis. At A Better Smile Dental Centres we use inhalation of nitrous oxide, also known as laughing gas.

Nitrous oxide is a wonderful way to reduce a patient’s anxiety because it is administered under the supervision of the dentist and can be quickly reversed when it is time for you to leave. Nitrous oxide induces a relaxed feeling and sends you into a dreamlike state.


In some cases, we use a moderate level of sedation called conscious sedation. Conscious sedation can be induced with oral medication or through inhalation.

Sometimes we use both oral sedation and nitrous oxide to achieve the most extreme relaxed state. While you are becoming more relaxed, you will be laying in a comfortable chair with a blanket in a dimly-lit, quiet room. Once you are relaxed and comfortable, a local anaesthetic is administered to provide you with a pain-free experience.

Depending on your needs, your oral sedation can last from two to six hours. To ensure your well-being, it's best to arrange for a companion to take you home.

Deep: IV sedation

Deep sedation is the state between conscious and unconscious. During deep sedation, the patient is unable to respond to commands. This is best done with IV sedation where the sedative is directly administered into your circulatory system.

Sleep sedation dentistry with IV sedation enables even the most anxious people to undergo dental treatment. During treatment you will not experience any pain or discomfort, and when you awake after the procedure you will have no memory of the treatment. To ensure your well-being, you should arrange for a companion to take you home.

Sedation Dentistry
Additional Information

Who administer the sedative?

Dr. Joel Kligman and Dr. Simon Briggs are expert in Twilight Sleep Dentistry or IV Sedation.

We also offer the services of a licensed medical anaesthetist for those patients with special needs.

Will I be asleep?

Yes. In most cases you will be in a state partway between conscious and unconscious, but you would be able to respond to commands.

What types of procedures will you perform sedation dentistry for?

Sedation dentistry is appropriate for any short or long procedure, from simple fillings to crowns, implants, extractions, etc.

It is highly recommended for anxious or nervous patients.

Will there be side effects from the sedation dentistry?

The only side effects reported are occasional mild drowsiness for 24 hours. A dry mouth is a common but transient effect of the sedation.

Is fasting required?

Yes. Please do not eat for 6 hours before your scheduled appointment. If your appointment is in the morning, this means nothing to eat or drink from midnight the night before. If you have an afternoon appointment, it may be OK to have a small snack or meal beforehand but you must finish it no less than 6 hours prior to your treatment. If in doubt, please do not eat.

Remember, if you are not properly fasted, your appointment may have to be rescheduled.

What I should wear?

Please wear comfortable clothing, remember that most dental treatments are prolonged.

Short sleeves are recommended to allow a blood pressure cuff to be fitted to one of your upper arms.

Avoid one-piece outfits, sometimes an adhesive patch needs to be placed on the side of your rib cage under your blouse or shirt.

Can I take my medications?

Yes, you can take your usual medications at the time you would normally have them, even within the fasting period. In this case, you can drink a small sip of water to swallow your pills.

If you are diabetic, please contact us to properly discuss your options.

What happen after the procedure?

After the procedure is finished you will have a brief recovery period after which you can go straight home. You must be accompanied home by a responsible adult.

Remember you cannot walk, drive, or take any type of public transport to get home. Neither, you should think to go to work or sign any legal document. In most cases, you can resume your normal life the next day after the procedure.

If you have not made arrangements to be accompanied home, your procedure may need to be rescheduled.
