When you look at dental floss, you ll notice there are two types - nylon and single filament. You can get nylon either waxed or un-waxed, in several different flavors. Nylon floss is made up of several strands of nylon material, meaning that it can shred, tear, or snag between the teeth if it gets caught on sharp teeth. If you notice a color change or a blackened area in your tooth, you should make an appointment with your dentist immediately. What you eat is a big contributor to cavities. 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. A dry socket is a condition where the blood clot that forms after an extraction detaches itself from the socket walls. Sometimes, the clot will dissolve, leaving the bone exposed to food, the weather, and even saliva. Once the bone is exposed, it can become inflamed. The inflammation that occurs is very painful, often times being a deep pain that makes you feel as if you are dying. These emergencies include broken teeth, teeth that have been knocked out, or teeth that have been forced out of the socket. With some emergencies, the cheeks, lips, or gums will have cuts or abrasions on them from where the teeth come out of the socket. If you ve had a tooth recently knocked out, the first thing you should do is look for that tooth. Chewing tobacco is a common contributor to toothaches and tooth pain, as the tobacco will eat away at your teeth until there is nothing left. It doesn t take long for it to happen either, especially if you have been chewing for a long time. Smoking can trigger toothaches as well, as the smoke is bad for your teeth and eats away at them as well. Even though the pain may go away, the problem will still be there until you go to the dentist and get it treated. Although the dentist is the preferred way to go, you may have to wait on an appointment, or the toothache may occur on a weekend or a time when the dentist isn t available. Your best advice is to seek dental care ASAP, as the infection can always return at any given time.
