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. If he isn t willing to talk about it with you or do things to help you relax, you should look into a new dentist. You can always tell who the better dentists are by the type of facilities they have. Dentists who have a lot of customers or nice offices, have established themselves and proved that they are indeed the best. If this happens, all you can really do is go back to the dentist to get the problem fixed. If you have an exposed root or nerve, it can also be the cause of your toothache. This normally happens due to rough brushing, receding the gums and exposing the root. If the root is exposed, the air or liquid you drink can trigger a toothache. Although this is sick to say the least, this remedy was discarded in 1728, proven to be non effective and replaced by other more suitable treatment. As time passed, doctors proved that the best way to stop the pain was to clean and remove the nerve and pulp of the tooth. Root canals are a very common procedure these days, as they help to save the tooth by removing the dead or dying pulp. Dentists were just starting to come around, although they didn t have near the equipment and sophistication that they have these days. Even though teeth were pulled during these times, it normally happened with alcohol to numb the pain then pliers to remove the tooth. Throughout the course of time, herbs have proven to be very effective with stopping toothache pain. Although there are several toothpastes to choose from, Sensodyne is the preferred. It s recommended by dentists as being the best, simply because it affects the nerve of the tooth and stops the pain where it starts. Mouthwash can also help tooth sensitivity, providing it contains fluoride. You can also ask your dentist which mouthwash he recommends, as there are several to choose from.
