White lesions on the oral mucosa are chronic reaction to local irritation and are able to transform into malignancy. One of the common lesion that is associated with tobacco is oral leukoplakia, the features of which are not attributed to any lesion. Clinical appearance has been described as either homogenous or non-homogenous type. Rarely they are found in same individual. This case presentation is of a middle aged patient who wanted to restore a mandibular molar with a crown after having undergone endodontic treatment. The patient presented with a homogenous and a non-homogenous oral leukoplakia, one of which had undergone dysplasia. The mandibular first molar was grossly decayed, and was restored with a cast post two unit sliding system, fabricated through an indirect technique. The non-homogenous oral leukoplakia was treated through surgical excision while the homogenous type was left as such, with patient educated and motived to stop tobacco chewing. The mandibular molar was covered with a metal ceramic crown.
