There are many different things that can cause toothache. The pain can be unbearable at times, and it can be the worst time of our life. After it is over or someone we know had it, many of us wonder what caused it.

Several main causes of toothaches include decay, cavities, or a crack in the tooth. A crack will normally not appear to naked eyes and x-rays. Cracks can make you feel terrible pain, as the dentin (one of the four major components of teeth) and nerves was exposed to the air. If you don't get them fixed quickly they will get worse and worse.

If you often smoke, you will likely to get toothaches on a frequent basis. The smoke will eat away your teeth until there is nothing left. So you should stop smoking. It's not good for your health and your money.

Another reason for toothaches is pulp irritation which occurs after dental treatment. No matter how good your dentist are, the materials that were used to fix your tooth can end up causing pain later. The only way to fix it to return to your dentist and have him fix it.

If you have an exposed nerve on your teeth, it can also cause the pain. This usually happens due to rough brushing, which is exposing the root. Then when the root is exposed, the air or liquid in your mouth can trigger a toothache. To prevent this, brush your teeth gently.

So after you know what causes toothaches, you should know how to prevent it. You should brush your teeth and go to the dentist on regular basis. This means brush your teeth on a daily basis, and go to your dentist for regular checkups. If you get a toothache go to your dentist and have the tooth fixed.

Don't forget to brush your teeth and change your brush head regularly.
