How long can hard-boiled eggs stay out at room temperature? The Easter basket looks empty without them. Your friendly U.S. Department of Agriculture says you can keep those colorful eggs in the Easter basket or out for an Easter egg hunt for absolutely as long as you like  as long as it's not more than two hours. Otherwise, it says, they should be kept in the refrigerator.
Dry socket can sometimes occur following a tooth extraction. This is caused when the socket where the tooth once was is slow to heal. The condition can be very painful for three to five days or so. Your dentist will advise you of what post extraction regimen to follow in order to help prevent this condition.
Tooth decay is a common cause of tooth loss in younger people. Bacteria are normally found in your mouth. These bacteria change foods -- especially sugar and starch -- into acids. Bacteria, acid, food pieces, and saliva combine in the mouth to form a sticky substance called plaque. Plaque sticks to the teeth. It is most common on the back molars, just above the gum line on all teeth, and at the edges of fillings. Plaque that is not removed from the teeth turns into a substance called tartar. Plaque and tartar irritate the gums, resulting in gingivitis and periodontitis. Plaque begins to build up on teeth within 20 minutes after eating. If it is not removed, tooth decay will begin. The acids in plaque damage the enamel covering your teeth, and create holes in the tooth (cavities). Cavities usually do not hurt, unless they grow very large and affect nerves or cause a tooth fracture. An untreated cavity can lead to a tooth abscess.
