Have you ever had that awkward experience when you drink a cold beverage and immediately feel a sharp pain in your teeth? You’re not alone. In fact, one in eight people has this same problem with tooth sensitivity. So what’s the cause? Believe it or not, tooth sensitivity such as this doesn’t have anything to do with cavities or even braces, the most common cause is brushing with too much force.
The Effects of Brushing Too Hard
Before, during and after undergoing orthodontic treatment, the concept of brushing your teeth regularly was drilled into your brain as the best way to maintain good oral health and hygiene. While some take this advice and brush as recommended (every morning, every night and shortly after each meal), some people translate this to mean that they should be brushing more aggressively. This is NOT the case.
Over-brushing or brushing too aggressively can wear down the protective layers that make up the tooth enamel. Additionally, it can push the gums back further – exposing the dentin layer under the enamel even more. This dentin layer leaves the teeth vulnerable to the nerves underneath that cause pain and discomfort when exposed to hot, cold and acidic foods.
