How Thyroid Hormones Regulate Salivary Gland Activity
Your salivary glands need a steady metabolic rate to make enough saliva. When thyroid hormone levels go down, these glands work slower. This is why hypothyroidism and dry mouth often go together.
Thyroid hormones also affect the autonomic nervous system, which controls things like saliva flow. When this system is off, glands can’t make enough saliva. This is why hypothyroidism dry mouth is common. It shows why treating dry mouth thyroid disease needs a full approach.
Can Underactive Thyroid Cause Dry Mouth and Medication Side Effects?

Living with a thyroid disorder means understanding how your medication affects your mouth. Many wonder if an underactive thyroid can cause dry mouth. It’s key to know that both the autoimmune activity and hormone replacement therapy can affect your mouth.
The Impact of Hashimoto’s Thyroiditis on Oral Health
