Sedation Dentistry Available in Lethbridge

A significant number of people do not visit the dentist for regular checkups because they are too fearful or suffer from dental anxiety. At 5th Ave. Dental Clinic in Lethbridge, we offer sedation dentistry, an excellent way to provide a safe, anxiety-free dental experience to those who are afraid of the dentist. We provide general anesthetic, laughing gas and anti-anxiety medication at our clinic.


Dr. James Evanson is trained and authorized to administer sedation for dental procedures. As safety and compliance are two important aspects of treatments, sedation dentistry offers both the individual and the dentist the best alternative. Book your appointment today.

PLEASE NOTE: Whatever the form of sedative, it is essential to be accompanied by a caregiver. Sometimes, sedatives are provided the night before the dental visit, which means that driving to or from the appointment is not advisable.

Advantages of Sedation Dentistry

Sedation dentistry is preferred for the following reasons:

  • Anxiety is alleviated

  • Few side effects

  • More can be accomplished during each visit

  • No needles

  • No pain

  • Perfectly safe

  • Procedures seem to take less time

General Anesthetic

General anesthetic is given to the patient to induce mild sleepiness. It is usually a combination of inhaled gasses and IV medication. It can be delivered through a nose hood or with an injection. There are different medications that can be used. This type of sedative makes the patient completely unconscious and unaware of the pain and discomfort during any procedure. General anesthetic is rarely used but used nonetheless in cases of extreme anxiety or for traumatic dental procedures. We make sure to inform you of any side effects and the effect it will have on you during the process.

Laughing Gas

Laughing gas or Nitrous oxide is used as a mild sedative. It is delivered through a nose hood and is administered throughout the entire procedure. Nitrous oxide elevates your 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. There are few side effects associated with nitrous oxide, and it has been safely used in dentistry for many years.

Anti-anxiety Medication

Anti-anxiety medication is given to patients who suffer from dental anxiety. These medicines calm the patient so that the procedure goes smoothly, without the patient panicking at the sight of the dentist’s tools. Some sedatives do not cause sleep and usually dull the senses. This means that most patients cannot remember the pain, smells or noises associated with the procedure. Sedation dentistry medications are classified as benzodiazepines.


We use medication such as:

  • Valium® – With amnesic properties and a long half-life, this sedative is usually used for time-consuming, complex procedures.

  • Halcion® – Usually used to treat insomnia, it is an effective sedative with amnesic properties. As it has a short half-life, Halcion® is useful for shorter procedures.

  • Ativan® – Known for reducing anxiety, this sedative has amnesic properties and a medium half-life. It is used for treatments shorter than two hours.

  • Versed® – This sedative has the shortest half-life and is used for visits that will take less than 30 minutes. It alleviates anxiety in much the same way as nitrous oxide.

The estimated length of the procedure determines which type of drug is going to be most effective. We make sure you are fully informed of the effects of the medication before we prescribe it to you.
