Same patient — why can she not close her lips when applying lipstick?
Show answer and explanation
Correct answer: A. Teeth are too long, preventing lip closure
- A. Correct, per the case description. Overly long anterior teeth physically prevent the lips from closing fully together, consistent with the patient's specific complaint.
- B. Excessive freeway space would more likely present as looseness/clicking rather than specifically preventing lip closure due to tooth length.
- C. Posterior tooth contact issues would not specifically explain anterior lip closure problems.
- D. Insufficient horizontal overlap is not identified as the cause in this case; tooth length (vertical dimension of the anterior teeth themselves) is the stated issue.
