Wisdom teeth are the third molars in both upper and lower dental arches. They are a valuable asset to the mouth when healthy and properly positioned.
But, when the jaw isn't large enough to accommodate wisdom teeth, they can become impacted (unable to come in or misaligned). Wisdom teeth may grow sideways, emerge only part way from the gum or remain trapped beneath the gum and bone.
Extraction of wisdom teeth is generally recommended when:
Sometimes the wisdom tooth fails to erupt completely through the gum bed and the gum at the back of the wisdom tooth extends over the biting surface, forming a soft tissue flap or lid around the tooth called an operculum.
Each individual wisdom tooth is unique and depending on how it grows, it can have different impact on bones and/or tissues. Their varied developments such as impaction, horizontal or slant placement may effect other teeth and cause troubles. They have to extracted out and is a highly skillful job being performed by our Maxillofacial surgeon. The following 4 impactions are commonly found in patients cases. If the impaction is between the third molar and part of the second molar, this kind is called bone impaction. It can subcategorized into vertical, horizontal, and angular depending on the way they are intersecting.
Impaction would cause pathosis inside the cheek bone or jaw bone.
Besides leading pathosis, horizontal placement would hurt the hard tissue of the second molar to cause toothache and cavities
Besides leading pathosis, angular placement would hurt the hard tissue of the second molar to cause toothache and cavities.
The wisdom tooth almost erupts out of gum, or its half erupts out of gum to cause pseudo-pocket. Besides leading pathosis, it easily tracts food debris and causes gum irritation.
