What Causes Tooth Sensitivity and How to Manage It

Dec 12, 2025 | Dental Care

Tooth sensitivity can sneak up on you. It happens when the protective layer of enamel wears away or gums recede, exposing the dentin underneath. This can make your teeth hurt when they are exposed to hot, cold, sweet, or acidic foods and drinks. You don’t have to love tooth sensitivity, though. Rochester patients can get treatment for sensitive teeth. 

Full Heart Dentistry helps Rochester patients find relief from the sharp discomfort of tooth sensitivity. Here’s what might be causing your tooth sensitivity and what you can do about it.

Why Are Your Teeth Sensitive All of a Sudden?

It can feel like tooth sensitivity shows up out of nowhere. One minute you are enjoying a cold drink, and the next you are wincing in pain. That sudden zing of pain might seem like a minor annoyance at first, but it could be your body’s way of telling you something is off. 

Your teeth are protected by enamel. It’s the hardest substance in your body. Beneath the enamel is a softer layer called dentin, which connects to the nerve in your tooth via tiny tubes. If the enamel on your teeth wears down or if your gums recede, dentin can be exposed. When that happens, you’ll start to feel those sharp jolts of pain. 

Is it a Sign of Something More Serious?

Tooth sensitivity isn’t always about worn enamel. It could also signal: 

  • A developing cavity 
  • Gum recession or early gum disease
  • A cracked or chipped tooth 
  • Tooth grinding in your sleep 

When sensitivity starts to become an issue, it’s time to check in with one of our dentists

What Are the Most Common Causes of Tooth Sensitivity? 

In our Rochester dental office, we see many patients who are struggling with sensitive teeth. Often, the root cause comes down to one of these issues: 

  • Enamel erosion from acidic foods or drinks. Sodas, citrus, vinegar, and wine can slowly wear away enamel, especially if you consume them often over a long period of time. 
  • Brushing too hard. Scrubbing your teeth (especially with a hard-bristle toothbrush) can cause enamel loss and gum recession. 
  • Gum disease. When gums pull away from the teeth, they expose the roots. These areas don’t have protective enamel, making them more sensitive. 
  • Tooth grinding. Clenching or grinding your teeth, often in your sleep, wears down enamel and increases the risk of developing sensitivity or cracking a tooth. 
  • Cracked or chipped teeth. A break in the enamel can expose the sensitive inner layers of the tooth and could even let bacteria in. 
  • Recent dental procedures. Teeth whitening, fillings, or crowns can temporarily increase sensitivity. Teeth can be especially sensitive in the first few days after a treatment. 

How Can You Treat or Manage Tooth Sensitivity?

The first step is getting a diagnosis to determine what’s causing the issue. From there, our dentists can recommend a treatment plan tailored to your needs. 

You can take steps today to protect sensitive teeth at home:

  • Use a toothpaste made for sensitivity (such as Sensodyne or Pronamel)
  • Brush gently with a soft-bristled toothbrush
  • Avoid acidic snacks and beverages
  • Rinse with a fluoride mouthwash to strengthen enamel

If sensitivity doesn’t improve at home, there are professional treatment options that may help. These include: 

  • Fluoride varnishes to reinforce enamel
  • Dental bonding to protect exposed root surfaces
  • Nightguards for grinding and clenching
  • Gum therapy like LANAP® to address gum disease
  • Restorative dentistry, like crowns or fillings, if decay or damage is found

We offer all of these services right here in our Rochester office. We’ll walk you through every step so you feel informed and supported.

When Should You See a Dentist About Sensitive Teeth?

Occasional sensitivity might not be urgent, but it’s still worth a chat with a dentist. If your sensitivity is getting worse or happening more consistently, it’s time to make an appointment. 

Don’t wait if you notice: 

  • Sensitivity that lasts more than a week
  • Pain from just one or two teeth
  • Sensitivity paired with visible cracks or gum recession
  • Lingering discomfort even with sensitivity toothpaste

Ignoring the signs could mean missing the early stages of something more serious. The sooner you act, the easier the treatment usually is.
