Experiencing Ineffective Local Anesthesia?
You might find this a bit odd, but can someone actually develop a resistance to local anesthetics? Whenever I visit the dentist, I seldom experience complete numbness, and topical lidocaine creams fail to provide relief for me. The benzocaine patches, meant to alleviate pain from bee stings, don’t seem to help either. Initially, I suspected that the topical treatments might be defective, but they were still well within their expiration dates. To confirm, I had a friend try them out, and she reported that they worked effectively for her. For context, I’m a 17-year-old female who is not on any medications, and I have no history of smoking, vaping, or drinking alcohol.

It’s understandable to be concerned about the effectiveness of local anesthetics, especially when they don't seem to work as expected. While developing a resistance to local anesthetics is rare, individual variations in response to these medications can occur due to factors like anxiety, metabolic differences, or even anatomical variations in nerve pathways.
Explanation
Local anesthetics like lidocaine and benzocaine work by blocking nerve signals in the area they're applied. If you're not feeling numbness as you should, there could be a few reasons:
- Anxiety: High levels of anxiety during dental procedures can heighten sensitivity and make it feel like the anesthetic isn’t working.
- Metabolic Factors: Everyone metabolizes medications differently, which can affect how well they work for you.
- Anatomical Variations: Differences in how your nerves are structured or where they're located can influence how effectively local anesthetics target them.
Next Steps
-
Communicate with Your Dentist: Share your experiences with local anesthetics during your visits. Dentists may be able to adjust the type or amount of anesthetic used based on your feedback.
-
Try Nerve Blocks: If topical anesthetics aren't effective, mention this to your dentist. They may consider using a nerve block anesthetic, which might provide better numbness during procedures.
-
Address Anxiety: If anxiety contributes to your pain perception, discuss relaxation techniques or sedation options with your dentist to help ease your experience.
-
Pain Diary: Keep a log of your experiences with various anesthetics, noting what worked and what didn’t, so you can provide precise information to your dental care provider.
-
Self-Care Techniques: Practice breathing exercises or mindfulness before and during your appointments to help manage anxiety, which could improve your overall experience.
If you continue to have issues despite trying these steps, further investigation with a healthcare provider may be warranted to rule out specific sensitivities or other underlying issues.

Understanding Brown Skin Spots
I’m a 26-year-old woman and recently, I’ve observed the emergence of light brown, flat spots on my skin. These spots primarily appear on my hands, neck, chest, and back, though some are scattered across other areas of my body. A couple of faint spots are also present on my face. They are completely smooth—neither raised, scaly, nor itchy—and they feel identical to the surrounding skin. It seems like their number is gradually increasing. Initially, I suspected they might be sunspots. However, considering that I have minimal exposure to sunlight—I rarely spend time outdoors and when I do, it’s only for short periods—I find this unlikely. I’m curious if anyone else has faced a similar situation. What might these spots indicate? Should I be worried, or is it sufficient to keep an eye on them? Any insights or recommendations would be greatly valued!
