Wisdom Tooth Removal
Wisdom teeth are the last teeth to erupt in permanent dentition. Usually, the eruption of these wisdom teeth occurs between 17 to 25 years of age. When these teeth fail normal eruption they are known as impacted teeth. Impaction of these third molars may be due to
- Insufficient space in the dental arch for the accommodation of these new teeth
- Positioning and the anatomy of the tooth within the bone
- Dense/thick bone above the underlying unerupted teeth
- Thick fibrous soft tissue hindering normal eruption
Impaction may be partial or complete. In partial impaction, any one of the cusps are visible and incomplete impaction they are completely embedded within the bone or soft tissue and recognized only through radiographic examination. Impacted third molars may or may not be symptomatic.
Signs and symptoms to recognize you are once such patient experiencing impaction:
- Severe, constant or periodic pain usually radiating to ear and neck and head region.
- Restricted mouth opening
- Bad breath or Halitosis/malodor
- Extraoral and or intraoral swelling
- Fever with possible lymph node palpation
What can be done?
- When eruption path of the teeth is normal, only possible hindrance being thick soft tissue covering it can be excised under local anesthesia to pave the wave for the underlying tooth.
- If there is no sufficient room for the accommodation of new teeth in the dental arch its safer to extract them to protect the other existing teeth.
What happens if not extracted?
- The severity of the pain increases
- Pericoronal infection
- Alveolar abscess
- Possible ear infection
- Dental caries affecting adjacent erupted teeth
What is Disimpaction of wisdom tooth?
- Dis impaction is surgical removal of an impacted tooth under local anesthesia.
- It is a daycare procedure, depending on the severity of impaction they can take about 40 to 60 minutes.
- Incision, mucoperiosteal flap elevation, bone guttering and sectioning of a tooth if required, extraction of the tooth, hemostasis followed by the closure of incision with sutures.
