Wisdom teeth, also known as third molars, are the last teeth to erupt. They occur between the ages of 17 and 25, often with a number of potential problems: Your jaw may not be large enough to accommodate them, and they may become impacted and unable to break through your gums. Your wisdom teeth may break partway through your gums, causing a flap of gum tissue to grow over them. Food and germs can be easily trapped under the flap and your gums easily become red, swollen, infected and painful. More serious problems can develop from impacted teeth, such as infection, damage to other teeth and bone, or the development of a cyst. One or more of your wisdom teeth may come in at an awkward angle, with the top of the tooth facing forward, backward, or to either side.   (Show full text)

Proper brushing is the first step to maintaining healthy teeth and gums. It takes at least two minutes using a recommended technique to do a good job of brushing your teeth. Whether you are using a manual or a power toothbrush, you should spend at least 30 seconds in each quadrant of your mouth (upper right and left, lower right and left).
