Definition of Dry Mouth
Dry mouth occurs when there is not enough saliva production in the mouth. Salivary production can decrease due to medications, cancer or other pathology, alcohol-containing mouth rinses, medical conditions, illegal drugs or medical treatments - such as radiation therapy. Not only is dry mouth uncomfortable, it can also make teeth more susceptible to decay due to lack of "washing" by saliva.
What causes dry mouth? Dry mouth or xerostomia is due to salivary gland shutdown, decreasing the amount of saliva flow inside of your mouth. It can be due to uncontrolled or underlying health conditions, but may also be associated with common everyday prescription medications, nutritional practices and the oral hygiene products that you use. Dry mouth can also appear suddenly, such as with anxiety or nervousness.
Dry mouth can have a number of causes, both internal and external. Examples include Sjogren's syndrome, diabetes, anemia, dehydration, side effects from medical treatments, damage to salivary glands and nerve damage. Certain prescription drugs list dry mouth as a side effect as well. Some of the types of drugs that can cause this are antidepressants, antihistamines, blood pressure drugs, anti-diarrheal, muscle relaxants, urinary incontinence drugs, Parkinson's disease drugs, chemotherapy, diabetes medications, and Alzheimer's disease drugs.
Signs And Symptoms
The signs and symptoms of xerostomia are very straightforward:
- Dry mouth
- Difficulty chewing or swallowing
- Oral tissues such as lips and cheeks sticking together
- Redness or irritation of the oral tissues
- Increase in tooth decay
- Gum disease
- Oral ulcers
- Bad breath or halitosis
- Inhibited sense of taste
Some other things to look out for are saliva that seems thick or stringy, cracked lips, sore throat, fungal infection of the mouth, or increased plaque, tooth decay and gum disease.
Dangers And Health Risks
Our body produces saliva to keep the mouth lubricated throughout the day. This allows us to speak properly, chew and swallow our food, and reduce the amount of tooth decay by keeping a constant flow of saliva over the surfaces of the teeth. When we have a decreased amount of saliva in our mouth it can cause problems like raw, sore gums or tongue and an increased level of tooth decay.
Erosion of the teeth and gums may occur due to lack of lubrication in the mouth. (1) A decrease in saliva may also contribute to periodontitis or gum disease, due to the body’s inability to protect the areas around the teeth from increased plaque buildup. (2) Dry mouth can sometimes be a warning sign for conditions such as:
- Sjögren's syndrome
- Lambert-Eaton syndrome
The following are all conditions and diseases that can stem from bacteria and the diseases caused by dry mouth. They include bad breath, bleeding gums, canker sores, gingivitis, gum boils, gum disease, gum infection, loose teeth, mouth sores, periodontal disease, pyorrhea, receding gums, red gums, Sjogren's syndrome, swollen gums, thrush, tooth abscess, trench mouth, osteoporosis, cardiovascular disease, cancer, pre-eclampsia, preterm births, metabolic syndrome, rheumatoid arthritis, stroke, erectile dysfunction, bacterial pneumonia, and diabetes.
How To Prevent Dry Mouth
- The prevention of dry mouth involves careful reading of prescription and over-the-counter medication labels. Literally hundreds of everyday drugs such as decongestant use may cause dry mouth.
- Use alcohol-free oral hygiene products. Many over-the-counter mouth rinses contain alcohol, which may kill of bacteria but also dry out your mouth. When the mouth is dry, there may be an increased risk of decay or infection due to the washing action of saliva.
- Stay hydrated and drink plenty of water. If you allow yourself to become dehydrated or don’t have a nutritionally balanced diet, your saliva flow may be compromised. Avoid salty foods.
- Keep your mouth free of bacteria. Boost your oral hygiene in order to help do the job of your saliva, thoroughly removing plaque buildup from around the teeth and gums.
