The bulk of your teeth are composed of dentin, which is covered but your enamel on the outside, your gums, and also by cementum on the roots. Inside the dentin is a lot of nerve endings, so once dentin is exposed your nerves respond painfully to hot and cold!
Numerous factors can cause your dentin to become exposed, take a look:
- Periodontal disease: Gum disease is a common cause of tooth sensitivity. Over time if plaque builds up on your teeth, your gums can become inflamed leading to gingivitis. If not treated, periodontal disease can arise which leads to gum recession and exposed roots and dentin. Be sure to keep up with regular brushing twice a day, flossing, rinsing, and dental check-ups to ensure that your gums stay healthy.
- Improper brushing techniques: It's true, there is a science to brushing! Brushing aggressively can cause your enamel to wear down and eventually expose your nerve endings within dentin. Make sure you have a soft bristled tooth brush and that you are brushing toward the gum line lightly to remove bacteria within your gum pockets.
- Teeth clenching and grinding: Someone may have told you that you grind your teeth at night, or you may notice that you're clenching your teeth throughout the day. Clenching and grinding can cause your enamel to wear down and also cause headaches and cracks within your teeth. Let your dentist know if you are clenching or grinding and treatment options such as a night guard can be discussed.
- Tooth decay: If you begin experiencing cold sensitivity on a regular basis, it is important to let your dentist know because it could be a sign of tooth decay. Tooth decay and fillings that have cracked can cause exposure of dentin and result in tooth sensitivity.
- Tooth whitening/dental treatment: Sometime bleaching agents and recent dental procedures such as fillings and crowns can cause temporary sensitivity. Be sure to let your dentist know when you begin experiencing sensitivity.
- Acidic diet: Foods and beverages with high acid content, including sodas, coffee, juice, pickles, etc., can cause enamel erosion and exposure of dentin.
