An abscessed tooth is an infection within a tooth that has spread to the root tip or around the root. This infection originates from the tooth's inner chamber, which is called the pulp chamber.. Contained within the pulp chamber are blood vessels and nerves, collectively called the pulp..
Earthworms prefer to eat at night, though, rather than in the day. That is why they are also called nightcrawlers. Besides adding nutrients to the soil, earthworms keep the soil healthy by tunneling. Worms do not have claws or paws to make tunnels, but they do have mouths. As they eat (and eat and eat), they create tunnels that keep the soil open and full of paths for water and air.
Their skin must remain moist for them to breathe. Like us, they still need to take in oxygen and expel carbon dioxide. However because they don't have lungs, this process happens though their skin. It's not uncommon to see worms coming to the soil surface after saturating rains. Some hold the view that they suffocate in water saturated soil because there isn't enough oxygen. However worms can survive for some time in water.
