What causes excessive saliva?

In general, "drool" refers to saliva. Excessive saliva may be caused by factors such as growth and development, dietary stimulation, excessive oral hygiene, gingivitis, or hyperthyroidism. If any discomfort occurs, seek medical attention promptly and receive symptomatic treatment under the guidance of a qualified physician. Specific causes are analyzed as follows:

1. Growth and Development

During childhood growth and development, stages such as teething and tooth replacement can stimulate the gums and salivary glands, leading to increased saliva production. Maintain good oral hygiene for children, clean teeth and gums regularly, and avoid excessive intake of irritating foods.

2. Dietary Stimulation

Spicy or sugary foods may stimulate the salivary glands to produce more saliva. Adjust eating habits by reducing intake of acidic, spicy, and sweet foods, drink plenty of water, and maintain adequate moisture in the mouth.

3. Excessive Oral Hygiene

Frequent brushing or use of irritating mouthwashes may also lead to increased saliva secretion. Reduce the frequency and intensity of brushing, use a soft-bristled toothbrush and mild toothpaste, and avoid using irritating mouthwashes.

4. Gingivitis

Poor oral hygiene habits can lead to gum inflammation. The inflammation stimulates the salivary glands to produce more saliva to help cleanse and repair damaged tissues. Symptoms may include oral pain, redness, swelling, bleeding, and bad breath. Patients should follow medical advice and take medications such as metronidazole tablets, cefixime capsules, or ibuprofen sustained-release capsules as prescribed.

5. Hyperthyroidism

Genetic factors or long-term exposure to iodine-deficient environments may lead to hyperthyroidism. Excessive secretion of thyroid hormones affects the body's metabolism and hormonal balance, thereby impacting the secretory function of the salivary glands. Symptoms may include palpitations, excessive sweating, and irritability. Patients should take medications such as methimazole tablets, propylthiouracil tablets, or metoprolol tartrate sustained-release tablets under a doctor’s guidance.

In daily life, it is important to maintain good oral hygiene, have regular dental cleanings, adjust dietary habits, drink plenty of water, and keep the mouth moist.
