You probably notice that you get more hangnails during the cold winter months. You might also notice that during the winter, your skin dries out really fast. Bingo! You've just hit on one of the main causes of hangnails. Anything that can dry out your skin, such as cold winter weather, harsh chemicals or frequent immersion in water can cause hangnails to develop.
It is not unusual for teeth to hurt after a filling or crown. If the filling is deep or near the nerve or pulp, the filling may ache or be sensitive for several days or weeks. When the cavity is close to the nerve, the body will build a layer of dentin over time to insulate itself from the pain transmitted to the nerve form the filling. Here are some usual reasons fillings will hurt after a tooth is filled: 1) Normal response to the trauma, this pain should subside in several days or weeks. 2) If the tooth hurts only when you bite, the filling may be too high, especialy if this in the first or only tooth you hit when you bite.
Generally the deeper the decay, the more likely the tooth is to hurt. However we canât always 100% predict when your teeth will be sensitive after dental work. I love to use the following analogy to describe pain after dental treatment. Teeth are like cups of water. Every time work is done on a tooth, you pour water into that cup. And you canât predict when that cup will run over and cause pain to the patient because every patient is different and ever tooth is different. I can do a large, deep filling on one person, and the tooth will never hurt.
