Understanding and Managing Sialadenitis: A Comprehensive Guide (2023)


Sialadenitis is a condition that involves the infection of the salivary glands, crucial components of our oral health system. In this comprehensive guide, we delve into the intricacies of sialadenitis, its symptoms, treatment options, and preventative measures.

What is Sialadenitis?

Sialadenitis occurs when the salivary glands, responsible for producing saliva, become infected. Saliva plays a vital role in maintaining oral health by killing germs, aiding in digestion, preventing bad breath, and protecting against tooth decay. The three primary salivary glands are located near the ears (parotid), under the tongue (sublingual), and under the bottom jaw (submandibular).

Symptoms of Sialadenitis

Identifying sialadenitis involves recognizing key symptoms:

  • Pain and Swelling: Affected glands become painful and swollen, causing discomfort in front of the ear, under the jaw, or inside the mouth.
  • Decreased Saliva Production: A noticeable reduction in saliva.
  • Dry Mouth: A common symptom associated with the condition.
  • Pain with Eating: Discomfort is experienced while consuming food.
  • Fever and Chills: General signs of infection may be present.

Diagnosing and Treating Sialadenitis

To determine the appropriate treatment, it is essential to differentiate between bacterial and viral infections. Bacterial infections often require antibiotics, such as dicloxacillin or cephalexin. Viral infections, typically affecting both sides of the mouth, usually resolve over time without medication.

Treatment options and relief measures include:

  • Hydration: Drinking plenty of water and fluids.
  • Sialogogues: Natural ways to boost saliva production, such as sucking hard candies or chewing sugarless gum.
  • Warm Compresses: Applying warmth to affected glands.
  • Gentle Massage: Massaging painful areas to express any infection in the glands or ducts.
  • Oral Hygiene: Brushing and flossing at least twice daily.

Antibiotics for Sialadenitis

In bacterial infections, antibiotics like dicloxacillin or cephalexin are commonly prescribed. It is crucial to complete the prescribed course even if symptoms improve to prevent recurrence.

Causes of Sialadenitis

Understanding the causes is integral to prevention. Decreased saliva production, often due to dehydration, increases the risk of bacterial infection. Medications like diuretics, antihistamines, beta blockers, or barbiturates can contribute to reduced saliva. Other triggers include certain viruses (mumps), Sjogren’s syndrome, anorexia nervosa, and salivary gland stones.

Preventative Tips

Proactive measures to prevent sialadenitis include:

  • Hydration: Staying well-hydrated is key.
  • Oral Hygiene: Maintaining good oral hygiene with regular brushing and flossing.
  • Vaccination: Preventing viral sialadenitis through vaccines like measles, mumps, and rubella.


Sialadenitis is a manageable condition, and understanding its symptoms, treatment options, and preventative measures is crucial for maintaining optimal oral health. If symptoms persist or worsen, consulting a healthcare professional is advised for personalized guidance. This comprehensive guide aims to equip you with the knowledge needed to navigate sialadenitis effectively.
