Nicotine Stains on Teeth: Causes, Removal, and Prevention

Nicotine stains are yellow-brown extrinsic discoloration from tar and nicotine in tobacco smoke (cigarettes, cigars, pipes, vaping). They adhere to pellicle and penetrate enamel pores over time.

Removal

• Professional cleaning (prophylaxis): Ultrasonic scaling + polishing removes surface stain.
• Whitening: In-office (high-concentration H₂O₂ + light) or custom trays (10–22% carbamide peroxide) — penetrates enamel to bleach chromogens.
• Whitening toothpastes: Mild abrasives + low peroxide; limited effect on deep stains.

Prevention

• Cessation — only definitive prevention.
• Rinse with water after smoking.
• Electric toothbrush + whitening toothpaste.
• Regular dental cleanings (q6mo).

Vaping also stains (flavorings, propylene glycol). Intrinsic stains (tetracycline, fluorosis) require different approaches.
