Wisdom teeth / Third molars/ Lower last tooth grow in at the back of the mouth, behind your molars. There is a set on the bottom as well as the top. Wisdom teeth often grow in a crooked, sideways, or otherwise misaligned. As they grow in, they can push on other teeth, causing problems of overcrowding and misalignment for them as well.

Why are third molars called wisdom teeth?
One major dental milestone that usually takes place between the ages of 17 and 21 is the appearance of your third molars.
Historically, these teeth have been called wisdom teeth because they come through at a more mature age.
When they come through correctly, healthy wisdom teeth can help you chew.
Function of wisdom teeth:
Wisdom teeth are believed to be "evolutionary relics", and were helpful to our distant ancestors who ate diets that consisted of rougher foods like sticks and reed plants.
As teeth wore down or fell out, wisdom teeth provided replacements.
Most mandibular third molars also upright and acceptably replace the second molars after extraction due to caries.
Nowadays, with modern advancements in oral hygiene and softer diets, we don't need these replacement teeth, but they still grow in.
Essentially, our mouths can hold 28 teeth, but including wisdom teeth, we have about 32 teeth all vying for space.
Impaction means the wisdom tooth partially erupt through gums which allows habitat for bacteria to enter around the tooth and causes an infection.
Impacted teeth creates pressure on the adjacent teeth and decreases the amount of bone present on the side of impacted tooth.
Food lodgement will be there and difficult for brushing and flossing, will leads to tooth decay, gum swelling.
NOT TOO COMMON, cyst formation around the wisdom teeth. this causes destruction of bone.
TYPES OF IMPACTION:

- Bad breath
There are varying degrees of impacted teeth. some partially impacted showing crowns to some fail to penetrate gums fully impacted.

Gum disease and decay due to difficult access to cleaning make them prone to food lodgement and infection.
