What level of sedation to use
From a psychological perspective, anxiety reduces most effectively when your brain has the chance to learn that a situation is safe. This learning happens through experience while you are aware, not when you are fully sedated or unconscious.
Choosing the “right” level of sedation is not about finding the strongest option available, it’s about finding the lowest level of support that allows your patients to feel safe, comfortable, and able to engage with care. This is an important distinction, because while sedation can make dental treatment possible in the short term, the long-term goal for many patients is to feel increasingly confident and less reliant on it over time.
Sedation exists on a spectrum, from mild support (like relaxation techniques or nitrous oxide) through to deeper options such as IV sedation or general anaesthesia. It can be incredibly helpful, and for some patients, essential. However, more sedation is not always better.
Why “less is more” when it comes to sedation
Using the least amount of sedation necessary has several advantages:
Greater sense of control: Lighter sedation allows your patients to remain aware, communicate, and build trust with your dental team
Faster recovery: Minimal or no sedation means fewer side effects and quicker return to normal activities
Skill-building: Your patients develop coping strategies that make future visits easier
Reduced dependence: Your patients are less likely to feel that they “need” sedation every time

The role of behavioural strategies
Behavioural and psychological approaches such as communication, gradual exposure, relaxation techniques, and cognitive reframing are the most effective ways to create long-term change.
These approaches work by:
Reducing the perceived threat of dental care
Building familiarity and predictability
Increasing your sense of control
Changing how your brain interprets dental experiences
Over time, this leads to reduced anxiety and improved attendance, rather than simply getting through a single appointment.
Example
A patient who uses breathing techniques, stop signals, and a supportive dental environment may initially feel anxious but gradually becomes more comfortable over several visits. In contrast, a patient relying solely on deep sedation may complete treatment, but their underlying fear remains unchanged.
What does the research say?
There is strong evidence that behavioural interventions provide more durable improvements in dental anxiety than pharmacological approaches alone.
A systematic review by Wide Boman (2013) found that cognitive behavioural therapy (CBT) significantly reduced dental anxiety and improved long-term attendance, with effects maintained over time.
Research published in Behaviour Research and Therapy by Kvale Guri et al. (2004) demonstrated that CBT was highly effective in treating dental phobia, with most patients able to receive treatment without sedation afterwards.
The American Dental Association and National Institute for Health and Care Excellence both emphasise that behavioural management should be the foundation of care, with sedation used as an adjunct where needed.
Finding the right balance
This doesn’t mean sedation should be avoided. For some patients, particularly those with severe anxiety, trauma, or urgent treatment needs, sedation plays a crucial role. The key is how it is used.
A balanced approach might look like:
Starting with behavioural strategies and communication
Adding light sedation (e.g. nitrous oxide) if needed
Reserving deeper sedation for specific situations
Gradually reducing reliance on sedation over time
A collaborative decision
Ultimately, the “right” level of sedation is personal. It depends on your patients level of anxiety, past experiences, and the type of treatment required.
The most important thing is that the decision is made collaboratively, with you understanding your patients fears and helping them to choose an approach that supports both their immediate comfort and long-term confidence.
The goal isn’t just to get through today’s appointment, it’s to make future visits feel easier, more predictable, and something you feel capable of managing.
