There really is nothing you can do, as crowns can sometimes come off or the filling can sometimes come out. 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. 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. Normally, this will result in a filling, crown, or root canal, although you won t have to have the tooth removed. Dentists always look to save teeth, as they don t like to remove a tooth unless they absolutely have to. If the tooth has become abscessed, the dentist will put you on antibiotics such as penicillin until the infection has subsided enough to remove the tooth. The main problem many people have against flossing is the fact that it can result in bleeding of the gums. Anytime you floss and get between your teeth and around your gums, the floss will rub against your gums, resulting in bleeding. Many people take this the wrong way, and immediately stop flossing, usually for good. If you eat a lot of sweets or drink a lot of soda, you will be at a higher risk for cavities. Foods that are rich in sugar or starch are eaten by bacteria found in plaque, which will produce acids that eat through teeth. This acid is very harmful to teeth, as it can eat through the dentin and enamel in no time at all. This type of fracture is almost always found below the gums, normally under the bone. If a root fracture is found near the crown of the tooth, it will normally prove to be fatal. Sometimes, you can save the tooth with a root canal, even though it is normally lost later on due to an abscess of the bone that surrounds the fracture.
