White rice-grain raised particles on the tongue, if small in size, are usually likely to be a white tongue papilla covered with a more pronounced filiform papilla, a normal physiological tissue. However, if the white rice-grain raised particles are larger, it is considered to be some pathological condition, which is a manifestation of thrush, and may also be oral herpes, flat moss of the tongue, etc. Common causes and treatments 1. Thrush: It can be flaky or punctate and can spread to the tonsils in severe cases. This disease is common in infants and young children, and can also be seen in frail adults. At this time, white rice-sized raised particles are not easily wiped away, and there is usually no pain when the infection is mild. Since thrush is caused by fungal infection, mycoplasma and fluconazole are commonly used clinically to control candida infection so as to achieve the purpose of treatment; 2. Oral herpes: white rice-sized raised particles on the tongue may also be caused by herpes virus infection, at which time the patient usually also has fever, cough or local pain and other symptoms. For this type of patients, first need to use a certain proportion of benzalkonium bromide solution gargle, control the oral infection, and then give acyclovir, vaxilovir and other oral antiviral drugs for treatment, with high fever also need to take oral ibuprofen, acetaminophen and other drugs for heat treatment; 3, tongue lichen planus: the cause of this disease is unknown, with genetics, infection, immunity, as well as diabetes, hypertension and a variety of other diseases Patients in the early stage of the disease, the surface of the tongue will have obvious gray-white patches, presented as white rice-grain-sized raised particles, and later will gradually change to dark red. Patients are mainly dependent on hormonal treatment, such as topical application of prednisone and tretinoin cream under the guidance of a doctor, and gargling with chlorhexidine in the presence of infection. The statement that there are white rice grains raised on the tongue is too vague to be accurately judged. For the sake of health, patients are advised to seek medical examination in time to clarify the specific cause. However, no matter which oral disease is related to oral hygiene, so in daily life, we should pay attention to daily brushing, rinsing after meals, less smoking, less betel nut, and pay attention to the hygiene of the oral environment to help reduce the occurrence of oral diseases.
