Introduction
Oral whitening is generally not oral cancer. It may be caused by smoking, oral leukokeratosis, white edema, etc. Long-term smoking can lead to mucosal irritation from tobacco, resulting in reactive whitening and thickened keratinization, including whitening of the palate, known as nicotine stomatitis. In addition, oral whitening could also be due to white sponge nevus. Patients are advised to avoid cold exposure, fatigue, and refrain from consuming spicy or irritating foods.

1. Smoking
Long-term smoking can lead to mucosal whitening and thickened keratinization due to tobacco irritation. Whitening on the palate is known as "nicotine stomatitis." If white patches appear along the occlusal lines of the cheeks or lips, they are referred to as smoker's patches. Discontinuing smoking usually leads to spontaneous improvement.
2. Oral Leukokeratosis
White patches appearing along the upper and lower occlusal lines—areas subject to biting or friction—are commonly seen in obese individuals. Increased mucosal keratinization occurs due to tooth friction, particularly at the edges of the tongue and occlusal lines, resulting in white discoloration. Treatment may include topical application of sodium bicarbonate solution or chlorhexidine solution under medical supervision.
3. White Edema
Obese patients may develop white edema due to frequent friction along the occlusal lines, sometimes accompanied by slight stretching, leading to pale mucosa. Treatment under medical guidance may include cytidine iodide lozenges or Shuangliao Houfeng powder.
In addition, oral whitening could also result from white sponge nevus. Patients are advised to avoid cold exposure, fatigue, and refrain from consuming spicy or irritating foods.
