Not being numb enough
“What if I can still feel everything even after the anaesthetic?”
What does it feel like?
A common concern among patients is the fear that anaesthetic will not work properly or that they will feel pain during treatment despite being numbed. This fear can be persistent and difficult to shake, even for patients who have previously had successful experiences.
Patients often describe feeling hyper-aware during treatment, focusing on every sensation and questioning whether they are truly numb. Even normal feelings such as pressure or vibration can be interpreted as potential pain, which increases anxiety.
This fear is often not about what is happening in the moment, but about what might happen. The anticipation that something could suddenly hurt can make it difficult to relax.
Why might it develop?
This fear is commonly linked to past experiences where anaesthetic took longer to work or felt incomplete. In some cases, conditions such as infection can affect how well anaesthetic works, which may have contributed to these experiences.
Hearing stories from others about anaesthetic “not working” can also reinforce the fear. Additionally, anxiety itself plays a role. When someone is highly alert, their perception of sensations increases, making normal pressure feel more intense.

How it affects dental avoidance
Patients with this fear may delay treatment or feel extremely anxious leading up to appointments. During treatment, they may struggle to relax, ask for frequent reassurance, or feel unable to trust that they are comfortable.
This heightened awareness can make the experience feel more intense, even when the anaesthetic is working effectively.
What can help?
Modern dentistry includes multiple techniques to ensure effective anaesthesia. Dentists can adjust injection methods, use different types of anaesthetic, and provide additional doses if needed.
Importantly, dentists routinely test numbness before beginning treatment. Patients should feel comfortable asking for confirmation and speaking up if something doesn’t feel right.
Understanding the difference between pressure and pain can also help reduce anxiety. Many dental procedures involve sensations that feel unusual but are not painful. Hypnotherapy is an effective way to reduce your association between dental treatment and pain, helping you to experience what you’re feeling as a sensation rather than labelling the treatment as “painful”.
Stop signals provide an additional layer of reassurance, allowing patients to pause treatment at any time.
Over time, positive experiences can rebuild confidence. Once patients experience consistently comfortable treatment, this fear often decreases significantly.
