Immediate Improvement in Mouth Opening After Impacted Wisdom Tooth Extraction

Patient Complaint

The patient presented with restricted mouth opening (approximately two-finger breadth), causing difficulty in chewing, speaking, and maintaining oral hygiene. The condition was associated with discomfort in the lower back tooth region.

Clinical Findings

On examination, trismus (limited mouth opening) was observed. The patient was unable to open the mouth beyond two fingers, indicating muscular restriction and possible underlying pathology.

Radiographic Evaluation

An orthopantomogram (OPG) was advised for further assessment. The radiographic findings revealed a horizontally impacted mandibular third molar (wisdom tooth) embedded within the bone.

This impacted tooth was identified as the primary cause of inflammation and restricted mouth opening.

Diagnosis

Trismus associated with horizontally impacted mandibular third molar

Treatment Plan

Surgical extraction of the impacted wisdom tooth under local anesthesia.

Procedure Performed

• Administration of local anesthesia

• Reflection of mucoperiosteal flap

• Removal of surrounding bone to expose the impacted tooth

• Sectioning of the tooth (if required)

• Atraumatic extraction of the tooth

• Irrigation of the surgical site

• Suturing of the wound

Outcome

Immediately after the procedure, a significant improvement in mouth opening was observed.

• Pre-operative mouth opening: 2-finger breadth

• Post-operative mouth opening: 3-finger breadth

The patient experienced instant relief from restriction and improved jaw mobility.

Before and After Comparison

• Before Treatment: Limited mouth opening, discomfort, functional difficulty

• After Treatment: Increased mouth opening, improved function, relief from symptoms

Conclusion

Impacted wisdom teeth, especially those embedded in bone, can lead to complications such as pain, inflammation, and trismus. Early diagnosis through clinical and radiographic evaluation, followed by timely surgical intervention, can result in immediate functional improvement and enhanced patient comfort.

Clinical Note

Patients presenting with restricted mouth opening should always be evaluated for impacted third molars as a potential underlying cause. Prompt treatment helps prevent further complications.
