So, you’re enjoying a scoop of your favorite ice cream or sipping a hot chocolate, and suddenly ZING! A sharp, quick jolt of pain shoots through your tooth. If this has happened to you, you’ve experienced the joy (and we use that term loosely) of tooth sensitivity.
You’re not alone. Millions of people deal with this, and it’s your tooth’s not-so-subtle way of sending you an SOS. Think of that zing as a warning light on your car’s dashboard. You could ignore it, but that usually leads to a bigger problem down the road.
However, you don’t have to just “live with it.” Dr. Ed Lazer and our team in Baltimore, MD, are here to explain what’s going on and, more importantly, how we can make it stop.

Why Do My Teeth Feel Like That? The Science Behind the Zing
To understand sensitivity, let’s take a quick tour of a tooth. Imagine your tooth is like a castle:
- The Enamel: This is the tough, white, outer wall of the castle. It’s the hardest substance in your entire body, and its job is to protect what’s inside.
- The Dentin: This is the inner part of the castle, right behind the wall. It’s a lot softer and is filled with thousands of tiny, microscopic tunnels called “tubules.”
- The Nerve: Deep inside the castle is the nerve, the command center. It’s super sensitive and is supposed to be completely protected by the dentin and the enamel wall.
So, what causes the zing? Sensitivity happens when the castle walls are breached. If your enamel wears down or your gums pull back, it exposes the soft dentin underneath. Those tiny tubules act like little highways straight to the nerve. When something hot, cold, sweet, or acidic touches those exposed highways, BAM! The signal races to the nerve, and your brain registers it as a sharp pain.
The problem is that once your protective enamel wall is gone, it doesn’t grow back. That’s why sensitivity won’t just go away on its own. You need a dentist to help you rebuild the defenses.
What’s Knocking Down My Castle Walls? Common Culprits
Lots of things can wear down that protective enamel or cause your gums to recede. Here are the usual suspects:
- You’re Brushing Too Hard: This is a big one. Scrubbing your teeth with all your might doesn’t make them cleaner. It can actually scrub away your enamel and irritate your gums, making them pull back. Think of it as using a wire brush on a beautiful piece of wood. You’re going to damage the surface.
- Cavities (Tooth Decay): Cavities are literally holes drilled in your enamel by acid from bacteria. These holes are direct shortcuts to the dentin and nerve.
- Gum Disease: If your gums are unhealthy, they can start to recede or pull away from your teeth. This exposes the tooth roots, which aren’t covered by tough enamel at all, making them extremely sensitive.
- Cracks and Chips: A cracked tooth or a worn-out old filling can create an opening for sensations to get inside and bother the nerve.
- Grinding Your Teeth: If you clench or grind your teeth at night, you’re putting immense pressure on them, which can wear down the enamel over time.
Is This a Dental Emergency? When to Call the Dentist
That quick zing might not feel like an emergency, but any ongoing tooth pain is your body’s way of saying, “Hey, pay attention!” You shouldn’t have to wince every time you take a drink or change your eating habits to avoid pain.
While a single, brief twinge might not have you rushing to the phone, you should schedule an appointment promptly if:
- The pain is constant, not just a quick shot.
- It’s severe enough to disrupt your sleep or daily life.
- You notice visible damage, like a crack, a dark spot, or a hole in a tooth.
Getting it checked out early can turn a simple fix into a major one. It’s always better to be safe than sorry.
How Do We Fix It? Your Treatment Options
The great news is that we have many ways to stop sensitivity in its tracks. The right treatment depends on what’s causing the problem in the first place. After an exam, Dr. Lazer might recommend one of these solutions:
- For Early-Stage Sensitivity & Harsh Brushing: We might start with simple changes! This could include a prescription-strength fluoride gel to help strengthen your enamel, advice on using a soft-bristled toothbrush, and a lesson on gentle, circular brushing technique.
- For Cavities: If a cavity is the culprit, a simple dental filling will seal up the hole, blocking those highways to the nerve.
- For Gum Disease: We’ll need to tackle the infection first with a special cleaning called scaling and root planing. This deep clean helps your gums get healthy so they can reattach to the tooth and cover the sensitive roots.
- For Major Damage: If you have a large crack, a big cavity, or a severely worn-down tooth, a dental crown is often the best solution. Think of a crown as a brand-new, custom-made fortress for your tooth. This ceramic cap fits completely over the damaged tooth, shielding it from all outside sensations. Once a crown is on, the sensitivity is gone, and with proper care, your new crown can protect your tooth for 15 years or more!
