Does the idea of eating ice cream, sipping hot coffee, or even taking a breath of cold air make you wince? If so, you’re not alone. Tooth sensitivity (the medical term is “dentin hypersensitivity”) is one of the most common issues we see. It generally happens when your protective enamel wears thin, exposing the underlying layer of your tooth called “dentin.” This dentin is full of microscopic tubules that act like a direct pipeline to the nerve of your tooth. When a cold or hot trigger travels down that pipeline, it hits the nerve, creating that sudden, sharp “zing” that can stop you in your tracks.
The good news is that you can manage sensitivity. The very first thing to do is make sure you are not your own worst enemy by brushing too hard. Many people think a “scrub” is the best way to clean, but it actually has the opposite effect. Aggressive brushing with a hard-bristle brush will physically abrade your enamel and can cause your gums to recede, which just exposes even more sensitive dentin. Switching to a soft or extra-soft toothbrush and adopting a gentle, circular brushing technique is a game-changer. Think of it as massaging your gums, not scrubbing a floor.
In addition to adjusting your brushing habits, choosing the right toothpaste is key. Use a desensitizing toothpaste, which contains special ingredients that essentially “plug” those microscopic tubules in your dentin. It can take a few weeks to notice a difference, so be consistent. We also recommend paying attention to acidic food and drinks. Sodas, citrus juices, and energy drinks all chemically wear down your enamel. If you are going to have one, rinse your mouth with water right after, and wait at least 30 minutes before you brush. Brushing while your enamel is temporarily softened by acid is like scratching wet paint.
