Which smoking-cessation aid is LEAST favorable for a patient with a temporomandibular joint (TMJ) disorder?

  1. Nicotine chewing gum
  2. Transdermal nicotine patch
  3. Bupropion
  4. Varenicline
Show answer and explanation

Correct answer: A. Nicotine chewing gum

  • A. Correct. Chewing nicotine gum loads and strains the TMJ, and TMJ disease is a listed precaution/contraindication for nicotine gum (the lozenge shares this concern).
  • B. Incorrect. The transdermal patch delivers nicotine without any jaw movement — a good choice for TMJ patients.
  • C. Incorrect. Bupropion is an oral tablet with no chewing burden on the joint.
  • D. Incorrect. Varenicline is an oral tablet and does not load the TMJ.

Note: This corrects the source document, which keyed varenicline. CDC, VA, and dental references specifically flag nicotine GUM (and lozenges) as the NRT to avoid in TMJ disease because chewing strains the joint.
