Over time, many people begin to notice that their teeth may ache under certain circumstances. For some people, eating or drinking overly hot or cold foods can cause discomfort. For others, certain sugary foods can cause pain. Some people even experience discomfort when cool air passes over their teeth.
The development of this discomfort when there previously was not any may lead many people to wonder about the dentin in their teeth. Is it slowly becoming more sensitive? If this is your situation, you may find the following information to be of some help.
The Dentin Does Not Change in Sensitivity
Strictly speaking, your dentin retains the same level of sensitivity throughout your life. Why then does it seem that your teeth may become more likely to experience discomfort? This is because of damage to the outer protective layer of your teeth, the enamel.
Normally, the enamel protects the dentin—which is indeed sensitive—from exposure to things that might cause you discomfort. However, as the enamel is damaged or wears away, the protective coating loses its effectiveness. The result is that your teeth will begin to hurt in situations where they once would have been just fine.
Keeping Your Teeth from Becoming Sensitive
The key to protecting yourself from becoming too sensitive to things such as hot and cold food and drinks is to keep your enamel strong and healthy. Be sure that you use toothpaste with fluoride in it, as this mineral is used to strengthen and repair your enamel.
Further, be careful that when you brush your teeth you are not damaging the enamel. Use a toothbrush with soft bristles, and do not brush too hard. Avoid doing things that will damage your teeth, such as neglecting your oral hygiene routine. And be sure to have your teeth professionally cleaned every six months. These things will keep your enamel strong, and your dentin safely protected.
