The diagnosis of oral white lesions might be quite challenging. White lesions are only 5% of all oral pathologies. Smokeless tobacco (ST), also known as tobacco chewing, spit tobacco, dip, plug, or chew, is one of the well-documented agents that causes white lesions. The use of ST is associated with a variety of oral cavity lesions, including tooth decay, periodontal disease, tooth loss, leukoplakia, keratosis, oral cancers such as carcinoma-, verrucous carcinoma, and invasive squamous cell carcinoma. The prevalence and severity of lesions are dose related. Therefore, it can be best predicted by the amount, frequency, and duration of ST used. This case report highlights an unusual presentation of an adolescent child presenting in the orthodontic retention phase that was originally misdiagnosed as gingival recession due to treatment. A clinical examination of the oral cavity and careful history taken should be routinely performed in every patient presenting at a dental office.
口腔白色病变的诊断可能颇具挑战性。白色病变仅占所有口腔疾病的5%。无烟烟草（ST），也称为嚼烟、口含烟草、口嚼烟草、烟草块或咀嚼烟草，是已被充分记录的导致白色病变的因素之一。使用无烟烟草与多种口腔病变相关，包括龋齿、牙周病、牙齿脱落、白斑、角化病、口腔癌，如癌、疣状癌和浸润性鳞状细胞癌。病变的发生率和严重程度与剂量相关。因此，通过使用无烟烟草的量、频率和持续时间可以最好地预测。本病例报告强调了一名处于正畸保持期的青少年儿童的不寻常表现，最初因治疗被误诊为牙龈退缩。在牙科诊所就诊的每位患者都应常规进行口腔临床检查并仔细询问病史。
