Those who don t have sensitive teeth will have their gums covering the tubules, which prevents these types of things from happening. The idea here is to stop tooth sensitivity and keep the gums healthy. If you reduce the pressure you use when brushing your teeth, you ll find that your gums will remain healthy. Cavities are a very serious situation, and if left untreated, can result in the destruction of the tooth. This can also destroy the nerves as well, resulting in an abscess. An abscess is very serious, as it infects the root tip. If left untreated, an abscess can result in death. Although you may not realize it, cavities are a very serious matter that can quickly spread to something even more serious. You can get toothpaste that will prevent toothaches, stop sensitivity, and prevent things such as tartar and gingivitis. Toothpaste is the best way to protect your teeth, therefore you should always ask your dentist what type of toothpaste he recommends for you. To get the most out of brushing, you ll need to have a good toothbrush. Cracks can make your tooth feel as if it is exploding, as they expose the dentin and nerves to the air and anything else you put in your mouth. If you don t get them fixed, they will get worse, possibly leading to your tooth breaking off at the gums. Pulp irritation is another cause of toothaches, as it occurs after dental treatment. Once the decay has reached the pulp, it will keep eating away until the pulp has died. Once it dies, the toxins from the decay will be released into the root tip and make it s way into the jawbone. If not taken care of properly, the jawbone can become infected, which can lead to death in rare cases. To fix this problem, the dentist will need to perform a root canal. An IV sedation is the preferred way to have wisdom teeth extracted, as you ll be so relaxed you won t know what is going on. If you decide to just use local anaesthesia, which is numbing, you ll be fully aware of the procedure. You ll also hear the popping and cracking involved, which can make you feel quite uncomfortable.
