What Is Xerostomia(Dry mouth)?

Dry mouth, medically known as xerostomia, is a condition in which the salivary glands do not produce enough saliva to keep the mouth adequately moist. Saliva plays an essential role in protecting teeth, preventing tooth decay, aiding digestion, lubricating oral tissues and maintaining overall oral health.

Persistent dry mouth is not just uncomfortable—it can significantly increase the risk of cavities, gum disease, bad breath, oral infections and difficulty eating or speaking.

At Singh Dental Care, we identify the underlying cause of xerostomia and provide personalized treatment to relieve symptoms and protect your oral health.

Aging :- Although aging itself does not directly cause dry mouth, older adults are more likely to take medications that reduce saliva.

Medical Conditions :- Certain medical conditions may contribute to xerostomia, including:

• Diabetes

• Sjögren's Syndrome

• Parkinson's disease

• Alzheimer's disease

• Stroke

• HIV/AIDS

Radiation Therapy :- Radiation treatment to the head and neck can permanently reduce salivary gland function.

Chemotherapy :- Some chemotherapy medications temporarily decrease saliva production.

Dehydration :- Insufficient fluid intake, fever, excessive sweating, vomiting, or diarrhea can lead to dry mouth.

Types of Dry Mouth

• Temporary Xerostomia :- Usually caused by dehydration, stress, or short-term medication use and often improves after the underlying cause is corrected.

• Chronic Xerostomia :- Persistent dry mouth caused by long-term medical conditions, medications, or permanent salivary gland damage.

What Happens If Dry Mouth Is Left Untreated?

• Salivary Flow Assessment :- Evaluation of saliva production when indicated.

• Dental Examination :- Assessment for cavities, gum disease, oral infections and other complications related to dry mouth.

• Additional Investigations :- If necessary, referral for medical evaluation or blood tests may be recommended to identify underlying systemic conditions.

Treatment Options :- Treatment depends on the underlying cause:- 

• Hydration :- Increasing water intake throughout the day helps relieve mild symptoms.

• Saliva Substitutes :- Artificial saliva products may provide temporary relief.

• Saliva-Stimulating Products :- Sugar-free chewing gum or lozenge containing xylitol may help stimulate natural saliva production.

• Fluoride Therapy :- Professional fluoride treatments and prescription fluoride toothpaste help protect against tooth decay.

• Treatment of Underlying Medical Conditions :- Managing systemic conditions such as diabetes or Sjögren's Syndrome may improve symptoms.
