Wisdom teeth are usually the last teeth that erupt usually 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 (also known as operculitis, is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, including the gingiva (gums) and the dental follicle. The soft tissue covering a partially erupted tooth is known as an operculum, an area which can be difficult to access with normal oral hygiene methods.)
, 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..
