Sedation
Home / Sedation
Sedation dentistry can help patients who are anxious about dental treatment feel more comfortable during their procedure. Suitability is assessed against your medical history.
Sedation dentistry is often mistakenly thought to induce sleep. In fact, most sedatives allow the patient to stay awake during the procedure. Sleepiness is a side effect of some medications, but nitrous oxide, oral conscious sedation and IV sedation only work to calm anxiety throughout the dental visit.
Many sedatives can be taken by mouth, and sedation is used alongside local anaesthetic to reduce anxiety and discomfort during treatment. Some patients remember little of the procedure afterwards; effects vary from person to person. Risks, side effects and whether sedation is suitable for you are discussed at your consultation.
What kinds of sedatives are available?
The most popular types of dental sedatives are nitrous oxide, oral conscious sedation, and IV sedation. Different levels of sedation (mild, moderate and deep) can be utilized depending on individual needs. Before administering any sedative, the dentist must analyse the full medical history of the patient, as well as taking note of any current medications.
Here is an overview of some of the most common types of dental sedatives.
Nitrous Oxide
Nitrous oxide, or “laughing gas,” is used as a mild sedative. It is delivered through a nose hood and is administered throughout the entire procedure. Nitrous oxide elevates the general mood and can evoke a general sense of well-being. Most importantly, it relieves anxiety and reduces pain during the procedure. In addition, some tingling and numbness may be felt. Nitrous oxide has a long history of use in dentistry; possible side effects will be discussed with you beforehand.
IV Sedation
Intravenous sedation is a moderate type of sedation. Patients who have previously experienced IV sedation often report feeling like they slept through the entire procedure. IV sedation is administered via direct injection into the bloodstream, which means the effects are immediate. Sometimes patients feel groggy and sleepy when the IV sedatives are withdrawn. This is why it is important to bring a designated driver for the drive home.
