For patients with dental anxiety, one of the most common fears isnt just the pain or discomfort during a procedureits the anticipation and memory of the experience afterward. Even when a treatment goes smoothly, vivid memories of sounds, sensations, or emotional discomfort can make the next visit feel just as intimidating. At McLevin Dental Clinic in Scarborough, Ontario, we offer sedation dentistry not only to ease anxiety during the procedure but also to reduce procedural memory, allowing patients to heal without carrying the emotional weight of the visit.
In this blog, we explain how sedation dentistry affects memory, the different types of sedation that influence recall, and why this benefit can be life-changing for patients who avoid the dentist due to fear.
Understanding Procedural Memory in Dental Anxiety
Procedural memory refers to the unconscious memory of how an event unfolds, including the sequence of steps, physical sensations, and emotional reactions. In a dental setting, this can include:
The sound of the drill
The pressure or vibration during treatment
The feeling of being confined in the chair
The emotional tension of anticipating discomfort
Even when pain is minimal, patients with dental phobia often remember these experiences in great detail, reinforcing their fear for future visits.
How Sedation Dentistry Reduces Procedural Memory
Sedation dentistry works by calming the nervous system, reducing awareness, and in some cases, creating a partial amnesia effect. This means patients are less likely to form vivid, lasting memories of the dental procedureeven though they remain conscious and responsive during the treatment.
This effect is especially beneficial for:
Patients with moderate to severe dental anxiety
Individuals who have experienced traumatic medical or dental events
Children or adults with sensory sensitivity or neurodivergence
Anyone undergoing long or invasive procedures who wants a more relaxed recovery experience
Sedation Methods That Reduce Memory of Dental Procedures
Different levels of sedation produce different effects on memory. At McLevin Dental, we offer a range of options depending on your needs:
1. Oral Sedation (Pill Form)
Typically taken about an hour before the appointment
Induces a calm, drowsy state
Most patients remain conscious but remember very little of the procedure
Time seems to pass quickly, and anxiety is greatly reduced
Memory Benefit: Oral sedatives like benzodiazepines (e.g., lorazepam or diazepam) impair the brains ability to form new memories during the time they are active. This results in anterograde amnesia, where patients often recall very littleeven if they were awake and cooperative.
2. IV Sedation (Intravenous Sedation)
Administered directly into the bloodstream for fast-acting, controlled sedation
Patients are semi-conscious and can respond to instructions but often have no memory of the procedure
Offers the deepest level of sedation short of general anesthesia
Memory Benefit: IV sedation produces a stronger amnesic effect than oral sedation, especially beneficial for long procedures or severe dental phobia. Patients typically have zero awareness of the procedure after it’s complete.
3. Nitrous Oxide (Laughing Gas)
A mild sedative inhaled through a nose mask
Helps reduce anxiety and awareness but usually does not produce memory loss
Effects wear off quickly after the mask is removed
Memory Benefit: While nitrous oxide does not actively suppress memory like oral or IV sedation, it lessens emotional imprinting by keeping patients calm and relaxed, which in turn reduces the intensity of memory formation.
Why Reducing Procedural Memory Is a Game-Changer
For patients who fear the dentist because of what they remember from past visits, being able to undergo a procedure without vividly recalling the experience can:
Break the cycle of fear and avoidance
Improve confidence and comfort with each new visit
Make future appointments easier to schedule and attend
Reduce trauma-related responses in sensitive or phobic individuals
Allow for multiple treatments in one sitting without emotional overwhelm
It also helps reframe dental care as something manageable rather than frighteningespecially after positive experiences with little to no memory of discomfort.
After Sedation: What to Expect
While reduced memory is a benefit, its important to follow recovery protocols:
You may feel groggy after oral or IV sedationrest is recommended
Have someone escort you home, as your reflexes and memory may be impaired
Follow all aftercare instructions carefully, as you may not remember what was said during the appointment
Ask for written post-visit instructions or bring a support person who can take notes
