If it is accompanied by pain, it is often a recurrent oral ulcer; if it is not accompanied by pain, it may be oral lichen planus, squamous cell papilloma, common warts and so on. 1. Recurrent oral ulcers: If there is a small white spot with pain on the tip of the tongue, it is common to have recurrent oral ulcers, which are soybean or mung bean sized ulcers and may be white in color. 2. Oral lichen planus: the papular form of oral lichen planus causes changes in the epithelium, often manifested as whitish dots on the tongue. 3. Squamous cell papillomas: These are soft, non-tipped exophytic nodules that may appear white or reddish in color, are usually solitary, and are usually painless. 4.
