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 are kinda unique from person to person. Some people they come in just fine over a matter of a few weeks sometime in their teens (or later). Some people just never get them. Others they come in sideways. And for some like you, they seem to take forever to come in, and maybe never will fully emerge. Give it a few more weeks. Teeth do grow in slowly and wisdom teeth are good big ones. If you really think that its taking too long go back and see your dentist in a couple of weeks. Good luck.
