What causes toothache when eating hot or cold food?

Oral diseases are very common diseases. Some people experience toothache when their teeth are too cold or too hot. This may be gingivitis. At this time, you can take some antibiotics, pay more attention to your eating habits, eat less spicy and irritating foods, especially foods that are too cold or too hot, pay more attention to drinking water, and maintain good living habits.

Gingivitis refers to acute or chronic inflammation of the gum tissue. Gingiva refers to the oral mucosal epithelium covering the surface of the alveolar process and the neck of the teeth and the connective tissue underneath. Dental plaque is the initiating factor of gingivitis. Common symptoms of gingivitis include bleeding, red, swollen and painful gums, which may develop deeper into periodontitis. Gingivitis can be caused by bacterial infection, external stimulation, and food impaction, among which bacterial infection is the most common.

Chronic simple gingivitis

Chronic simple gingivitis only affects the gingival tissue and does not affect other periodontal tissues. This type of gingivitis is a chronic inflammation caused by plaque on the tooth surface near the gum margin. It has a clear cause and is more common in children and adolescents, with a prevalence of about 70%-90%. Gingivitis usually does not occur before the age of 4-5 years. Most cases start at the age of 5. With age, its prevalence and severity gradually increase, reaching a peak in adolescence. After adolescence, the prevalence of gingivitis slowly decreases with age, and the prevalence of gingivitis in adults is lower.

Marginal gingivitis

Marginal gingivitis: also known as simple gingivitis, the lesions are located in the gingival margin of the gingival crevice and the interdental papilla. Common causes include plaque, tartar, tartar, food impaction and ill-fitting dentures. The disease has particularly obvious subjective symptoms in the early stages. There is no pain, but the gums often bleed. In mild cases, it may be irritation bleeding, such as bleeding caused by brushing teeth, chewing, or slight collision.

Subjective symptoms

Subjective symptoms: In chronic gingivitis, patients often bleed when brushing their teeth or biting hard objects, or there are blood stains on the bitten food, which is the main reason for seeking medical treatment. However, chronic gingivitis generally does not have spontaneous bleeding, which can be distinguished from gingival bleeding caused by blood diseases and other diseases. Some patients occasionally feel local itching, swelling and other discomforts in the gums, and have bad breath.
