We just learned about Dental Notation - Palmer.
We learned before that sometimes teeth don't show up in the right places.
When a tooth doesn't show up in the right place it is called an Impacted Tooth.
The tooth that gets impacted the most is the wisdom tooth.
Most of the time when a tooth is impacted it's because there wasn't enough room in the mouth for the tooth to come up, so it gets pushed off to the side or below, and can come out of the gums at the wrong place.
