Conscious sedation

Conscious sedation helps reduce anxiety, discomfort, and pain during certain procedures. This is accomplished with medications and (sometimes) local anesthesia to induce relaxation.


Conscious sedation is commonly used in dentistry for people who feel anxious or panicked during complex procedures like fillings, root canals, or routine cleanings. It’s also often used during endoscopies and minor surgical procedures to relax patients and minimise discomfort. The specialist who sees you at your assessment appointment will discuss the different options and help you decide which is best for you.

Frequently Asked Questions


Is there anything that can help me with my fear of the dentist?

Yes. Some people are so frightened of the dentist that they will not go for dental treatment. They can overcome their fears with relaxation or sedation. Dentists today are sympathetic about these feelings, and you can ask your dental team about these ways to help.

What is sedation?

Your dentist may recommend an intravenous or ‘IV’ sedation. This is given by injection, either in the back of your hand or in your arm. The dose will depend on the amount of treatment needed and how long it will take to complete.

How will the sedation in the surgery affect me?

You become drowsy and are not aware of having any treatment, but you are still able to co-operate with the dentist. Most people cannot remember much about their treatment. Before the sedation, your blood pressure will be measured and during treatment your breathing and pulse will be monitored. The effects of sedative medicine take some time to wear off and your dentist will tell you how long the drugs will take to clear from your body. You won’t be able to drink alcohol, drive or work machinery during this time and it is important that you have
someone with you who can take you home and stay with you for the rest of the day.

How quickly does the sedation work?

The effect starts within seconds. Depending on the length of the procedure, the drugs will be topped up at regular intervals or will be dripping in continuously.

Will I be asleep during my treatment?

You will NOT be put to sleep – that is only allowed in a hospital. However, the drugs will make you feel relaxed and a bit drowsy, so patients do often fall asleep for parts of the treatment.

Will I have any pain?

During your treatment, you should experience no pain. If you were to feel any discomfort (eg. If the local anaesthesia starts to wear off during long procedures), you will be able to tell us so we can address that. If you have had a surgical procedure, you will have some pain after treatment.

Will I be aware of the treatment?

Yes, you will be aware of the treatment as it happens. However, you will be comfortable and relaxed and not care. Most patients have very little recollection of the treatment after the procedure, so patients often think that they must have been asleep.

How much will I remember?

Most patients have very limited recollection of the treatment after sedation. However, it is impossible to predict what you will remember. Remember: we do not sedate you to make you forget, but to make you comfortable. Forgetting some of the treatment does make the time seem to pass very quickly for the patient.

How will I feel afterwards?

You will feel drowsy. Most patients will go have a nap once they get home. The effects will gradually wear off, usually over 6-8 hours. You will need to be taken home by an able-bodied adult who will need to care for you until you have fully recovered.
