A solstice is an astronomical event that occurs twice each year as the Sun reaches its highest or lowest excursion relative to the celestial equator on the celestial sphere. The solstices and the equinoxes are connected with the seasons.
Adults can have up to 32 teeth. The wisdom teeth are the last to appear, right at the back of the mouth. They usually appear when you are between 17 and 25, although sometimes they appear many years later. People often have jaws that are too small for all 32 teeth to fit - 28 is often the most we have room for.
Wisdom teeth, or third molars, are the last teeth to emerge in a mouth. They typically erupt (emerge) when people are in their late teens or early twenties. Most adults have four wisdom teeth, but it is possible to have more, fewer or even none at all. If wisdom teeth grow in properly and fit around existing teeth well, they can be left untreated.
