Most of us don't think about the role that saliva plays in our oral health — until we don't have enough saliva. If your mouth has ever felt as parched as a desert, then you know how annoying and painful dry mouth can be. There are many causes of dry mouth, some temporary and others chronic. If you suffer from it, you may be at risk for certain dental conditions.
Causes Of Dry Mouth And The Problems It Can Create
Saliva, produced by your salivary glands, lubricates and cleanses your mouth of food particles and bacteria. Saliva also contains important digestive enzymes that act on the food you're chewing to start the digestive process. Without sufficient saliva flow, chewing, speaking and swallowing are difficult, and you may lose your ability to taste properly.
Dry mouth, also called xerostomia, is not a disease in and of itself. Dry mouth is actually a symptom of a condition that prevents the salivary glands from producing enough saliva. Stress, nervousness and dehydration can cause temporary dry mouth. The Indian Dental Association explains that the most common side effect caused due to medicines and extreme therapies is dry mouth (an insufficient supply of saliva). If the condition is neglected, it can lead to tooth decay and gum disease.
As you age, you may notice a reduction in saliva flow. Older adults often take medications and undergo treatments such as chemotherapy that cause the condition. Other procedures and conditions that damage the salivary glands and cause dry mouth are radiation treatment to the neck region, oral-cavity damage, cancer of the salivary glands and the autoimmune disease Sjögren's syndrome.
If your mouth is frequently dry, you are more at risk for getting cavities. With dry mouth, you don't have enough saliva to neutralise acids in your mouth or wash away organisms. This dry environment contributes to bacterial growth, and plaque builds up faster, which is a perfect recipe for tooth decay. You also lose the benefit of protective proteins and the ions in saliva that help with tooth remineralisation.
You also may be more vulnerable to mouth sores and infections due to dry mouth. One common fungal infection from which many people suffer is candidiasis, sometimes called oral thrush. This painful condition causes bad breath and makes tasting and swallowing difficult. Those who wear partial or full dentures are more prone to oral thrush.
Relief from dry mouth is usually temporary, but there are a number of treatments that you can try. Drinking plenty of water, chewing sugarless gum, sucking on sugar-free lozenges and using over-the-counter moisture replacement products will provide some relief. Avoid alcohol and caffeine, smoking, salty and dry foods and acidic foods such as tomatoes, oranges and grapefruits. Also, limit your intake of carbonated sodas and sports drinks, which have a high acid content. The Indian Dental Association notes that amongst the conditions that your dentist might treat with acupuncture includes Xerostomia (Dry mouth problems).
Good oral hygiene habits are critical. You should brush and floss twice a day and be sure to use fluoride toothpaste and an alcohol-free mouthwash. Since there are so many causes of dry mouth, discuss your symptoms with your dentist. A professional can help you get to the bottom of the problem.
