What is dental sedation?

Conscious sedation is a carefully controlled technique using certain drugs which allows dental treatment to be performed with minimal stress.

What drugs are used?

The type of drug most commonly used are called Benzodiazepines. The drug most commonly used is called Midazolam ( Hypnovel ), though sometimes we may use others.

How are the drugs given?

Normally these are given by injection in the hand or arm. This allows for quick, predictable and controlled sedation. We may also use a drink or tablets first for those who do not like injections.

What are the advantages of sedation?

Sedation will make you calm, relaxed and removed from the procedure. You may forget or loose track of time while sedated, making the procedure seem shorter. Sedation often removes the need for general anaesthetic.

Will I be asleep?

No, you do not go to sleep and you will still be able to talk to us.  The sedative will make you feel drowsy. Sedation is not a general anaesthetic.

Will I feel pain?

No. Local anaesthetic is an important part of good sedation.

Is it safe?

Yes, it is very safe. The technique used preserves your natural reflexes and has a wide safety margin

Before Sedation

You should:

Take your medicines at the usual times.

Have a light meal about two hours before your appointment

Bring a responsible adult escort to the hospital with you, they will stay in the hospital and take you home after your treatment

Let us know of any changes to your medical history or medications, or if you are pregnant

Avoid wearing clothes with tight sleeves, wear sleeves that allow access to the top part of the arm

Remove any nail varnish from your fingernails as this interferes with our monitoring equipment (a pulse monitor is placed on your finger throughout treatment).

Avoid alcohol

Let your escort take you straight home in a car or taxi

Arrange for a responsible adult to stay with you, and look after you for the rest of the day
