Dental Health Tips: What Causes Sticky Saliva?

We do not usually think of the mouth as having a delicate balance and many moving parts, but there are a great many systems at work to ensure you can eat, speak and breathe without thought or effort. You mouth contains elements that eliminate bacteria, allow the passage of inhaled and exhaled air, and allow proper and discernible speech to communicate with others, and process food for proper digestion.

Some of the mechanisms and chemical processes are complex, and they mostly rely on healthy mucosal tissues and gingiva to work efficiently and in the background. Saliva is one of the essential ingredients for the functioning of the multiple oral mechanisms. Saliva is antibacterial and acts as a lubricant and moistening agent. Dry mucosal tissue is less resistant to bacteria. Dry tissue has a greater amount of friction and reduces the ability of the tongue to function in speech and wallowing food. Dry tissue does not trap bacteria and viruses before they can enter the airway.

So poorly functioning saliva has many roles in the mouth. Saliva itself has two main components, a thin fluid, and a thicker fluid. They combine for best effectiveness. When there are external or internal factors that change the consistency of saliva, then it does not function as well. You may see this as thick or sticky saliva.

What Causes Sticky Saliva?

The most important common reason for sticky saliva is dehydration.

When this happens, your body is not taking in enough fluids to replace fluids that are lost. This can happen during intense exercise, from being in the sun too long, during illness including vomiting or diarrhea, or from taking medications like diuretics for blood pressure. Other medications include decongestants, antihistamines, medication for anxiety and depression, blood pressure medication.
pain medication, and muscle relaxers.

An illness like a cold or seasonal allergy can cause a stuffy nose. Nasal congestion often forces you to breathe with your mouth open, which can dry your mouth and make your saliva thicker and stickier than usual.

Dry mouth can also come from tobacco and alcohol use or overuse. Alcohol is a diuretic and acts similarly to a medication for that purpose.

Pregnant women experience changes in hormonal levels that can affect salivary production and can cause dry mouth.

Prolonged anxiety can also result in discernible dry mouth.

Some cancer therapies affect the salivary glands from chemotherapy or from radiation therapy. Radiation therapy to the head and neck can disable the salivary glands causing a great deal of dry mouth and discomfort.

There are other less frequent causes of dry mouth which are rarer but can include:

Progressive, terminal motor neuron diseases such as ALS (Lou Gehrig’s Disease). Salivary stones that block salivary ducts. Sjogren syndrome affects your salivary glands and can cause dry mouth or obstructed salivary ducts. Cystic fibrosis is a genetic condition that alters the production of mucus, sweat, and digestive enzymes in the cells.
