But few teens actually get that much sleep regularly, thanks to factors such as part-time jobs, early-morning classes, homework, extracurricular activities, social demands, and use of computers and other electronic gadgets. Sleep deprivation might not seem like a big deal, but it can have serious consequences. Tired teens can find it difficult to concentrate and learn, or even stay awake in class. Too little sleep also might contribute to mood swings and behavioral problems. Drowsy driving can lead to serious â even deadly â accidents.
Necrotizing ulcerative gingivitis (NUG) is a condition affecting the gums that is caused by a bacterial infection. It is a form of periodontal (gum) disease. But unlike other forms, it typically develops quickly and causes moderate to severe pain. Necrotizing means that the condition destroys tissue.
Acute necrotizing ulcerative gingivitis (ANUG; colloquially known as trench mouth) is a common, non-contagious infection of the gums with sudden onset. The main features are painful, bleeding gums, and ulceration of inter-dental papillae (the sections of gum between adjacent teeth).he often severe gingival pain that characterizes ANUG distinguishes it from the more common chronic periodontitis which is rarely painful. ANUG is the acute presentation of necrotizing ulcerative gingivitis (NUG), which is the usual course the disease takes.
