Why Are My Teeth So Sensitive To Cold & Hot Foods?

What Causes Tooth Sensitivity?

We have all been there, excited to bite into an ice cream treat, or drinking our favorite blend of hot coffee before work, and then it hits. That sharp pain in the teeth because of a hot or cold food. The reason behind tooth sensitivity, specifically to temperature, lies in how our nerves work. As you may know, all over our body we have various nerve endings that register different feelings like hot/cold, pain, pressure, etc. In our teeth, these nerves are deep beneath the outer layers of the tooth. But as our teeth decay due to acidic or high-sugar foods, we lose the protective layer or enamel on our teeth. This can expose the nerves and register some painful responses when eating cold or hot foods. Additionally, our gums can begin to recede due to improper oral health habits. Combined with the loss of enamel, your teeth can be exposed to more pain when biting a popsicle or drinking some hot tea. 

How To Prevent Enamel Loss & Receding Gums

There are two main ways you can protect your tooth enamel: how you brush, and what you eat. Highly acidic or sugary foods/beverages can quickly strip enamel off of your teeth. Coffee, soda, tomato sauce, and even fruit juice all have high acidity. When you eat or drink beverages that are sugary and acidic you want to make sure you wash them out of your mouth quickly. If you have ever spilled a sugary beverage, you know that it leaves a sticky residue. Similarly, this residue can bind to your teeth and eat away at them as you go about your day. Simply chewing sugar free gum and drinking water can remove left over food and beverages that stick to the outside of our teeth. But nothing replaces good brushing and flossing habits. Brushing 2-3 times per day and flossing once per day can remove left over food particles that are stuck your teeth. And of course, when possible, limit the foods and beverages that weaken our teeth. 

Should I Use Special Toothpaste To Prevent Cold Sensitivity

You may see a bottle of toothpaste in the drugstore that says it is specifically made for tooth sensitivity, cavity prevention, whitening, or another similar claim. Truthfully, many toothpaste brands highlight one of the many things they do on the box. What you should really look for in a toothpaste brand is that it is approved by the ADA (American Dental Association). The ADA places a “seal of acceptance” on toothpaste brands that are recommended. Many toothpaste marketing companies will list one of many different claims on the box to simply a/b test what consumers are drawn to. In fact, many ADA recommended toothpastes do all of the aforementioned things from preventing tooth sensitivity, to decreasing tartar buildup, to preventing cavities.
