Adults who suffer from a dry mouth are more at risk for cavities, as they have a lack of saliva in their mouth. Dry mouth is very common, and is normally the result of medications, illness, and radiation treatment. Tobacco users will also suffer from dry mouth, as the tobacco will use up the saliva in the mouth and leave the user with nothing to keep his or her mouth moist. Whenever pressure, hot, or cold elements travel down the tubules, it will trigger the nerves and result in pain. 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. To get the right amount of time brushing, you should try using a stopwatch while you brush. When you brush your teeth, you should avoid using pressure but instead use short, gentle strokes. You should focus on hard to reach places, and make sure that you get the areas between your teeth as well. You should also make sure you get eating surfaces as well, along with your upper and lower gums. Even though this form of mouth disease cannot be reversed, you can put a stop to it s progression by going to your dentist on a regular basis and brushing your teeth a few times day. Periodontal disease is a serious condition, which is why you should always try to stop the progression or even better - never let your gums and teeth get this bad. You should always keep in mind that you are customer, and the dentist is the one who needs to make you feel relaxed. Never should you feel intimidated, as the best dentists will do everything they can to establish a sense of trust. Establishing trust is very important with the patient/dentist relationship. Although many aren t aware of this, root canals have been around for many generations. Many years ago, ancient civilizations used this method to save teeth that would have been lost otherwise. These civilizations offered root canals to those such as queens, kings, pharaohs, and the rich. The teeth from peasants were normally extracted then sold to aristocrats.
