If the thought of a dental drill makes your heart race, you're not alone. Dental anxiety is common, and it can keep people from getting the care they need. A new study tested whether an online cognitive-behavioral therapy (CBT) program could help. CBT is a type of talk therapy that helps you change negative thoughts and behaviors. The results are promising, but they come with an important twist: how sensitive you are to pain may determine how well it works.
The study included 499 adults with high dental anxiety, recruited from a dental school clinic in the northeastern United States. They were randomly assigned to either an online CBT program or a control intervention that matched the time and attention. The researchers measured dental anxiety using a standard scale at the start, then again at 1 and 3 months after the program.
Overall, the online CBT helped reduce dental anxiety. But the key finding was that baseline pain sensitivity, measured with a simple questionnaire, changed the picture. People with low pain sensitivity were significantly more likely to see their dental anxiety drop after CBT. Those with high pain sensitivity did not benefit as much. The difference was statistically significant, meaning it's unlikely to be due to chance.
This doesn't mean online CBT is useless for people with high pain sensitivity. It suggests they might need a different approach or a more intensive program. The study is a randomized controlled trial, which is a strong design, but the pain sensitivity finding is a statistical interaction, so it needs confirmation in future research. If you struggle with dental anxiety, talk to your dentist or a mental health professional about what options might work best for you.
