Intravenous sedation involves you having sedative drug/ drugs given to you by injection into a vein. The sedation makes you drowsy and helps reduce anxiety.
A flexible plastic tube called a cannula is put into a vein in the back of your hand or in your arm. A needle is used to put the cannula into place, and is then removed immediately. It is normal to feel a sharp scratch when the cannula is being put into place. Once the cannula is in place, the sedation drug(s) can be given. The cannula is left in place until the appointment is finished and you are recovered. It will then be removed before you go home.
During intravenous sedation you will still be aware of what is going on but will feel more relaxed.
You may experience a temporary loss of memory during the time you are sedated, however this is not the case for everyone. You may feel unsteady on your feet for some hours after the procedure. Your ability to think clearly and make judgements may be affected for the next 24 hours. You may experience forgetfulness.
Once you are sedated, the dentist will use numbing injections (local anaesthetic) for fillings and all teeth that have to be taken out. Some paste can be used to make the area beside your tooth numb. The injection will then be given through this numbed area to help make the procedure more comfortable.
It is usual to have at least two to three appointments. The first appointment will be an assessment when your dental treatment under sedation will be discussed and planned with you. The dental treatment under sedation will take place at second and subsequent appointments.
Your dentist and members of the dental team are trained to give sedation. They watch you closely and treat any problems that may develop. They are also required to use monitoring equipment during the sedation, to check your heart rate, breathing rate and oxygen levels. You will be observed until you have made a full recovery from the sedation.
Unlike a general anaesthetic, where you are completely asleep, the main benefits with intravenous sedation is that it is often safer, quicker and more convenient.
Your discharge home and recovery time will be quicker than having a general anaesthetic and all the treatment can be provided in the dental surgery rather than having to go to hospital.
Yes. As with the administration of any medicines, there are risks associated with intravenous sedation.
The common risks may include:
Very rare risks may include:
Sometimes the intravenous sedation can cause a person to share information of a personal nature. If you do share information, this will be treated confidentially.
It is important to let the dentist know your medical history, including any medications that you are taking. The dentist will need to know if you have ever had any problems with having either intravenous sedation or a general anaesthetic.
If you are or may be pregnant, or you are breastfeeding, please let the dentist know as soon as possible.
Yes, dental treatment can also be carried out in the following ways:
Just using an injection to numb the treatment area inside the mouth (local anaesthesia).
Oral sedation involves a medication given by mouth. Inhalation sedation involves breathing a gas through a nosepiece. Both methods still require local anaesthesia to make the mouth numb too.
This involves going to sleep. The risk of a very serious complication with this form of treatment is very rare, about 1 in 100, 000 for a healthy adult. The risk is therefore small but much greater than that of intravenous sedation.
Your dentist will discuss these different options with you and why they think intravenous sedation might be the best way of providing treatment for you
