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.
This also helps improve soil structure by creating a loose soil that is easily penetrated by roots. 2. Earthworms neutralize soil pH. Their castings are always closer to neutral than the original soil. The pH in acidic soils is lifted, and the pH in alkaline soils is reduced. 3. Earthworms gradually deepen the topsoil layer by burrowing into the sub-soil. and translocating fine mineral particles to the surface in the form of castings. 4. Earthworms solve waste problems by composting organic matter.
