Sedation Options We Offer

Different sedation options may be considered depending on your level of anxiety, the treatment planned, your medical history and individual circumstances. Your dentist will discuss which options may be appropriate for you.

Mild Sedation Option

Happy Gas (Nitrous Oxide)

Inhaled through a small nose mask, happy gas may help you feel calmer and more relaxed while remaining conscious and able to respond during treatment. The effects generally wear off quickly after the gas is stopped. Your dentist will advise when it is appropriate for you to leave the clinic and resume activities. It may be considered for patients with mild to moderate dental anxiety and for a range of dental procedures.

Mild-to-Moderate Sedation

Oral Sedation

You take a prescribed sedative tablet before your appointment. Oral sedation may cause relaxation and drowsiness. You remain conscious, although your awareness and memory of the procedure may be reduced. Requires someone to drive you home. It may be considered for some patients with dental anxiety or those undergoing longer appointments.

Deeper Sedation Option

IV Sedation ('Twilight Sedation')

Administered intravenously by an appropriately qualified practitioner. IV sedation can produce a deeper level of sedation while you remain responsive. Awareness and memory of the procedure may be reduced, although individual responses vary. Vital signs are monitored throughout. IV sedation may be considered for patients with significant dental anxiety or those undergoing longer or more complex treatment.

Who May Benefit from Sedation Dentistry

Severe Dental Anxiety

Patients who've avoided the dentist for years due to fear, or experience panic at the thought of treatment.

Sensitive Gag Reflex

A strong gag reflex can make even simple procedures uncomfortable and difficult to complete without sedation.

Difficulty Tolerating Dental Treatment

Some patients may find dental treatment difficult to tolerate despite local anaesthetic, and sedation may be considered where clinically appropriate.

Complex or Lengthy Treatment

Sedation may help some patients tolerate longer or more complex dental procedures where clinically appropriate.

Past Traumatic Experiences

Patients who've had painful or frightening dental experiences that have made them avoid care since.

Patients With Additional Needs

Patients with cognitive, behavioural or sensory needs who may find dental treatment difficult to tolerate.

Potential Benefits of Sedation Dentistry

Reduced Awareness or Memory

Some forms of sedation may reduce awareness or memory of the procedure. Individual experiences vary.

Supporting Longer Appointments

Sedation may help some patients tolerate longer appointments or multiple procedures where clinically appropriate.

Managing Dental Anxiety

Sedation may help some patients manage anxiety and tolerate dental treatment.

Accessing Dental Care

For some patients, managing dental anxiety may make it easier to attend and receive necessary dental care.

Frequently Asked Questions

Is sedation dentistry safe?

Sedation has potential benefits and risks, which vary depending on the type of sedation and individual circumstances. Appropriate assessment, monitoring and qualified practitioners are important when sedation is provided.

Will I be unconscious during treatment?

Not fully. "Sleep dentistry" is a popular term but most sedation leaves you technically conscious, your level of awareness and memory may be reduced depending on the type and depth of sedation. General anaesthesia (full unconsciousness) is not something we offer at the practice.

How do I prepare for a sedation appointment?

Fasting requirements vary depending on the type of sedation and your individual circumstances. You will be given specific preparation instructions before your appointment.

Can I request sedation even for routine treatment?

Yes. If anxiety is preventing you from getting regular care, sedation may be considered for some routine procedures where clinically appropriate. We will discuss your concerns and the options that may be appropriate for you without judgement.

How much does sleep dentistry cost?

Sedation is an additional cost on top of your dental treatment. The cost varies by sedation type. We'll provide a full quote at your consultation, and Some extras policies may provide benefits towards certain sedation services. Benefits vary between policies, so check with your health fund for your individual cover.
