Is Tooth Sensitivity a Sign of a Bigger Dental Problem?

If you’re concerned about tooth sensitivity—or simply haven’t seen a dentist in a while—we’re here to help.

If you’ve ever cringed while sipping something cold or felt a jolt of discomfort when brushing your teeth, you’re not alone. Tooth sensitivity is one of the most common dental complaints, but it’s also one that many people ignore—until it starts to interfere with daily life.

At The Dental Anesthesia Center in St. Louis, we often see patients who come in thinking it’s “just sensitivity,” only to find out there’s a more serious issue underneath. So, is tooth sensitivity something you can live with, or could it be a sign of a bigger dental problem?

I have NEVER had a positive experience with dentist…until now!! I was mind blown how kind the staff was, not just to me but to everyone! I have debilitating anxiety when it comes to dentists because of bad previous experiences, so I was very nervous. But, all the staff, including Dr. Thom, were very gentle, kind, and understanding. They took time to listen to all my concerns and address them, helping to put me at ease. I was also amazed how professional the whole office ran and how completely reliable they were. They easily guided me through the process and everything went so smoothly, including my sedation. I have never been treated so kindly by any dental office before, I was struggling to believe I wasn’t in some kind of dream. But. They really were that nice.

My recovery from sedation and all
The dental work they did to save my tooth was amazing, not a single issue! Dr. Thom even called personally to check on me a day later.

Coming back to put my permanent crown in was the same experience. They were all so kind,
Good about explaining everything they were doing and make the experience light and dare I say…fun.

I would drive 2.5 hours again in a heartbeat to do my work here. Best dental experience I’ve ever
had hands down!!!!!!! Thank you Dr. Thom for giving my life and tooth back. I’m so excited to not be in so much excruciating pain anymore!

Our adult daughter has cerebral palsy and requires being fully sedated when having anything done. The DAC was such a positive experience. Dr Hoffmann and his staff were kind and did great explaining things. As a mom, I had a lot of questions about how certain things would be done as usually she’s in her chair when getting examined at her local dentist and they had everything under control including transferring from her chair to the dentist chair and keeping her secured in the dentist chair as well as keeping her neck and legs comfortable. Many thanks to them!
Response from the owner:Thank you so much for your kind words. We’re grateful for your trust and happy to hear that you had such a positive experience with our team. Our goal is always to provide compassionate, attentive care in a safe and comfortable environment. We truly appreciate you taking the time to share your experience.

❓ What Causes Tooth Sensitivity?

Tooth sensitivity usually occurs when the protective enamel wears down or gum tissue recedes, exposing the softer dentin underneath. This layer has tiny tubules that connect to the tooth’s nerve—so when it’s exposed, pain can follow.

Common causes include:

  • Brushing too hard or using a hard-bristle toothbrush
  • Acidic foods and drinks
  • Grinding or clenching your teeth
  • Gum disease
  • Tooth decay or cavities
  • Cracked or chipped teeth
  • Post-dental procedure sensitivity

While some of these issues are minor and easily managed, others can signal a more significant dental problem.


🚩 When Sensitivity Signals a Bigger Problem

Tooth sensitivity may be your mouth’s way of telling you something isn’t right. If your sensitivity is sudden, severe, or getting worse, it could indicate:

🦷 1. Tooth Decay (Cavities) – When bacteria compromise enamel, decay sets in and can expose the inner tooth layers—leading to sensitivity, pain, and even infection.

🦷 2. Cracked or Fractured Tooth – Small cracks might be invisible, but can cause extreme discomfort. Left untreated, they can worsen and require more complex treatment.

🦷 3. Gum Recession from Gum Disease – If your gums are pulling away from the teeth, the exposed roots are vulnerable and highly sensitive. This often indicates gingivitis or periodontitiswhich can lead to tooth loss if left untreated.

🦷 4. Tooth Infection or Abscess – Sharp pain or prolonged sensitivity could be a red flag for infection, which may require a root canal or extraction.


🛑 Don’t Let Sensitivity Delay Your Dental Visit

For many patients—especially those with dental anxiety, special needs, or sensory sensitivities—even mild discomfort can trigger fear and avoidance. Unfortunately, this can allow minor issues to escalate into major ones.

At The Dental Anesthesia Center, we provide gentle care under sedation for patients who require additional support. Whether you’re dealing with anxiety, complex dental issues, or have a loved one with special needs, we make dental care safe, stress-free, and pain-free.


✅ What You Can Do About It

If you’re experiencing tooth sensitivity, don’t wait it out. Here’s what you can do:

  • Switch to a sensitive toothpaste
  • Avoid acidic foods and drinks
  • Use a soft-bristle toothbrush
  • Schedule a dental exam to identify the cause
