Sleep Dentistry

Sleep Dentistry - Hills Area

Sleep Dentistry is where your dental treatment is performed under conscious sedation. This is sometimes known as “twilight sedation”. It allows you to have your dental procedures done in comfort, without the anxiety that you may usually feel. Unlike general anaesthetic in a major hospital, this will be performed by our specialist anaesthetist in house.  It is very effective and recovery is very quick.  

This form of dentistry may be recommended if you would like to have multiple procedures or complex dentistry carried out in one session. This can help reduce the number of dental visits that you need and ensure that the sessions are comfortable and stress free.

At Castle Hill Dental care, we offer 2 forms of conscious sedation.  Call Us today to find out more

Fear of Dentistry

Did you know that fear of going to the dentist is one of the main reasons why people put off having regular dental treatment?

At Castle Hill Dental Care, we strongly believe in making every dental visit a comfortable and positive experience. It’s important not to let dental anxiety prevent you from receiving high-quality dental care, so that’s why we offer you various sedation options to suit your needs.


IV Sedation

This form of sedation induces a more dream-like state compared to inhalation and is administered by our fully qualified IV sedationist. However, like inhalation, patients are still fully capable of hearing and responding to questions.

Typically, patients under IV sedation will “wake-up” and have no recollection of the procedure itself or feel like no time has passed.
Although IV sedation is an effective sedation method, it is not recommended for the following people:

  • Pregnant women
  • If you have glaucoma
  • If you have lung or kidney problems
  • Elderly people
  • People with any existing allergies to sedative agents

Unlike inhalation sedation, IV sedation typically requires several hours before you can completely return to normal. An escort home and downtime after your appointment is always recommended for people opting to have IV sedation. However, the recovery is not as unpleasant of general anaesthesia (GA).

Inhalation Sedation

Our dentists are highly trained to administer inhalation, otherwise known as “laughing gas”. It is a safe and effective agent administered through a mask that fits over your nose.

It can help you relax and stay comfortable whilst ensuring you are still fully capable of hearing and responding to your dentist.

Inhalation is increasingly popular with both children and adults as it only requires a few short minutes to take effect and wear off!

Frequently Asked Questions

Will I be unconscious during IV sedation?

No. Unlike General Anaesthesia, you won’t be unconscious. You will still be able to breathe on your own, hear and responding to any questions and notify us of any discomfort.

You will, however, experience a deeper state of relaxation and many of our patients on IV sedation find that they don’t remember the procedure afterwards.

How long will I be sedated gor?

The length of time you will need to be sedated will depend on the length of time required for your dental treatment. Your dentist will be able to give you an approximate time frame so you arrange transport and an escort home from your appointment if undertaking IV sedation.

Are ther any long term effects for sedation?

There are no proven long term effects from intermittent use of sedation. Some people may feel ‘groggy’ and tired after their appointment if undergoing IV sedation but fully recover within 24 hours. Be sure to inform our trained IV specialist regarding any current or past health conditions and medications that may affect treatment.

Are there any special instructions pre sedation that I need to be aware of before my appointment?

If you are undertaking inhalation sedation, there are no special pre or post-treatment instructions. Onset will occur within minutes of administration and disappear within minutes of removing the mask.

If you are undertaking IV sedation, patients should refrain from eating or drinking at least 6 hours before your appointment and must complete a detailed medical history form prior to your appointment. Complete written instructions will also be provided prior to your appointment.
