When only part of the tooth has erupted into the mouth, it can create a flap of gum tissue that easily holds food particles and debris and is a hotbed for bacteria. Pericoronitis also can occur around a wisdom tooth that has not erupted at all and is still under the gums.

A full-size futon mattress is the most readily available size, measuring 54 inches wide and 75 inches long -- exactly the same as a full or double bed mattress. This size of futon mattress is what's typically found on the sofa-style futons that fold down into a bed. A queen-sized futon mattress is also a fairly common size, measuring 60 inches wide, 80 inches long, just like any other standard queen-sized mattress. Some futon sofas use queen-sized futon mattresses; these are a bit wider than the full-sized futon sofa frames since the cushions are wider as well.
