Wisdom teeth are usually the last teeth that erupt one around the age of 17 or 18. Not everyone has their wisdom teeth: most people require wisdom tooth extractions, for a number of reasons. A common misconception about wisdom teeth is they must be removed. Realistically, this is not the case.
• They are erupting in to an abnormal position tilted, sideways or twisted.

• They are trapped below the gum line, or impacted, due to lack of space in the dental arch.

• An infection, or pericoronitis, has developed from trapped food, plaque and bacteria.

• The way the patient’s teeth bite together has changed, causing malocclusion of the teeth and misalignment of the jaws.

• The erupted wisdom tooth lacks proper hygiene because it is hard to reach, resulting in tooth decay..
