During tooth inflammation, it is recommended not to eat spicy and irritating foods, such as chili, garlic, mustard, etc., because these foods are more irritating and may aggravate the patient’s painful symptoms. One should also avoid eating foods that are too hard, such as brittle bones, because tooth inflammation may make the tooth tissue more fragile and too hard foods may lead to tooth splitting, etc. During tooth inflammation, patients should eat lightly, brush and rinse their teeth carefully to maintain good oral hygiene, but food is not the main factor causing tooth inflammation. If the symptoms of tooth inflammation appear, it is recommended that the patient actively seek medical examination and targeted treatment according to the specific cause to avoid aggravation of the condition, which may affect the prognosis.
