Your dentist can perform tests on your gums and your teeth, to determine if you have it. If you do have periodontal disease, your dentist can tell you how to stop the progression and prevent things from getting any worse than they already are. To be on the safe side and protect your teeth and your gums, you should always go to the dentist for your regular checkups and cleaning. If you have chosen either laughing gas or an IV sedation, your dentist will administer either of the two before he gives you shots or goes any further. Once the medicine has taken effect, you normally won t feel anything or remember it. Laughing gas and IV sedation can put your mind at ease, so you won t be uncomfortable during your surgery or extractions. 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. Toothaches are very painful, and it may seem that no matter what you do - it seems to hurt more. In the dental world, toothaches can include such things as cavities, infections or abscess in the teeth or gums, debris that has been trapped between the teeth and gums, and trauma to the face, teeth, or the jaw. Using various tools and equipment, he will go down inside of the tooth and scrape away the nerves and dead pulp. This is a very effective procedure, although very time consuming as well. In most cases, a root canal can take several hours, although it is the only way to stop the dying pulp and save the tooth. If the bristles start to get worn down, they can tear away at your gums, leading to sensitivity. To get the most from your brushing, you should always use a bit of common sense and ask your dentist for his recommendations. Brushing your teeth will help keep them healthy, and prevent the buildup of plaque and tartar.
