Introduction
Fever usually refers to elevated body temperature. Swollen mouth along with fever may be caused by infections, allergies, gingivitis, tonsillitis, hand-foot-and-mouth disease, or other reasons. It is recommended to seek medical attention at a hospital, where a thorough examination under the guidance of a doctor can help identify the specific cause and allow targeted treatment to relieve symptoms. During illness, ensure adequate rest, maintain a light diet, and avoid spicy or irritating foods to promote recovery.
Fever generally refers to an elevated body temperature. Swelling of the mouth accompanied by fever may be caused by infections, allergies, gingivitis, tonsillitis, hand-foot-and-mouth disease, and other conditions.
1. Infection
Inflammation due to infection by pathogens such as viruses or bacteria can lead to symptoms including mouth swelling and fever caused by inflammatory stimulation. It is recommended to take antiviral medications such as Ganciclovir Capsules, Oseltamivir Phosphate Granules, or Ribavirin Granules under medical guidance to relieve symptoms.
2. Allergy
When exposed to allergens, the immune system releases histamine while fighting the allergen, causing blood vessel dilation and tissue inflammation, which leads to increased body temperature, skin redness, swelling, and itching. It is important to promptly avoid the allergen and, as directed by a physician, use antihistamines such as Chlorpheniramine Maleate Tablets, Diphenhydramine Hydrochloride Tablets, or Cetirizine Hydrochloride Tablets for treatment.
3. Gingivitis
This condition may cause pus to accumulate in gum tissues, forming oral abscesses that result in localized swelling, pain, and fever. It is advisable to take antibiotics under medical supervision. Commonly used medications include Amoxicillin Capsules, Cefixime Capsules, and Cefaclor Capsules to alleviate symptoms.
4. Tonsillitis
When tonsil tissues become inflamed, pus may accumulate within them, leading to suppurative tonsillitis, which causes localized swelling in the throat or mouth, often accompanied by fever. Follow your doctor's advice to take medications such as Cephalexin Capsules, Cephradine Capsules, or Cefixime Capsules to improve symptoms.
5. Hand-Foot-and-Mouth Disease
Viral infection triggers an inflammatory immune response, resulting in elevated body temperature and pain in the tongue, oral mucosa, and pharynx. It is recommended to take fever-reducing medications such as Ibuprofen Suspension, Paracetamol Suspension, or Compound Paracetamol and Amantadine Tablets under medical supervision.
Patients are advised to visit a hospital for evaluation. Under a doctor’s guidance, thorough examinations can help identify the exact cause of illness and allow targeted treatments to relieve symptoms. During illness, ensure adequate rest, maintain a light diet, and avoid spicy or irritating foods to support recovery.
