White spots on the gums are likely to be in the early stages of gum ulcers, or if the tooth corresponding to the gum area has periapical inflammation, when a sinus tract is present in the mucosa as a way to drain pus from the root tip. In the early stage of the appearance of sinus tracts there is also the appearance of white dots on the gums, and if the gums are white reticulated, it suggests the development of lichen planus on the gums. Gum ulcers can be treated by applying topical dexamethasone patch gel, antibiotic film, open throat sword spray, and recombinant human epidermal growth factor gel. If the gum lesion is caused by periapical inflammation, the first step is to treat the inflammation of the tooth, which requires root canal treatment to eliminate the inflammation, and the changes in the mucosa at the gum will disappear. If the mucous membrane of the gums grows flatulence should be temporarily observed, and when the flatulence becomes painful, local injection of hormone treatment in the flatulence is required.
