This study assessed taste changes after removing all four third molars. While a temporary reduction in bitter taste perception was noted, overall gustatory function remained largely unaffected post-surgery.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Sensory Neuroscience
  • Dental Anesthesiology

Background:

  • Third molar (wisdom tooth) extraction is a common surgical procedure.
  • Potential complications include altered sensory perception, such as taste disturbances.
  • Understanding the impact on gustatory function is crucial for patient care.

Purpose of the Study:

  • To evaluate the extent of taste alterations following the surgical extraction of all four third molars in a single session.
  • To quantify changes in taste sensitivity at one and six months post-operation.

Main Methods:

  • Twenty-seven patients undergoing complete third molar removal under local anesthesia and sedation were recruited.
  • Gustatory function was assessed using whole-mouth and localized taste tests with sucrose, NaCl, citric acid, and quinine hydrochloride.

  • Taste perception was measured pre-operatively, and at one and six months post-surgery.

    • Main Results:

    • A statistically significant decrease in the intensity of quinine hydrochloride (bitter taste) on the palate was observed one month after surgery (P < 0.05).
    • This taste alteration recovered to preoperative levels by the six-month follow-up.
    • No significant overall changes in gustatory function were detected across the tested modalities and time points.

    Conclusions:

    • Surgical removal of all four third molars can cause transient, localized taste disturbances, specifically for bitter stimuli.
    • Long-term gustatory function is generally preserved after third molar extraction.
    • The findings suggest that temporary taste changes are a possible, but usually reversible, outcome of this procedure.
