Introduction
After quitting smoking, tobacco stains on teeth will not shed automatically and require professional cleaning or daily oral care to address. Mild stains may gradually fade after 1–2 months of consistent daily care, while more severe stains typically require professional treatment for removal. The exact timeline depends on the severity of the staining and the cleaning method used. In daily life, after quitting smoking, it's important to maintain good oral hygiene habits and schedule regular dental check-ups.
一般情况下，戒烟后牙齿上的烟渍不会自行脱落，需通过专业清洁或日常Nursing干预，轻度烟渍可能在1-2个月日常Nursing后有所淡化，较严重烟渍需专业处理后才能去除，具体时间与烟渍程度、清洁方式相关。具体分析如下：
烟渍是尼古丁、焦油长期附着在牙齿表面形成的色素沉着，这类物质会渗透到牙釉质微小缝隙中，仅靠戒烟后自然代谢无法去除。若烟渍较浅，坚持使用含氟牙膏、牙线，配合定期用温水漱口，同时减少咖啡、浓茶等深色食物摄入，1-2个月后牙齿表面色素可能逐渐淡化，视觉上烟渍有所减轻。
若烟渍形成时间长、颜色深，日常Nursing难以见效，需通过洗牙、冷光美白等专业方式处理。洗牙可快速去除牙齿表面烟渍，通常1次Treatment后就能明显改善；冷光美白针对深层色素，可能需要多次Treatment，整体周期约2-4周。
日常Life中，戒烟后保持良好口腔清洁习惯，定期进行口腔Examination，能Prevention新的色素沉着，维持牙齿洁净。
