Most people have experienced a time or two when their mouth felt drier or more parched than it ever was previously. It may have even made speaking, eating and swallowing uncomfortable. Dry mouth (xerostomia) is a temporary decrease in the amount of saliva your body produces, and unfortunately, some suffer from it repeatedly – which can compromise another aspect of their oral health.
If you’re suffering from constant dry mouth, knowing the cause and how to find relief can go a long way in preventing more serious dental complications.
Causes of Dry Mouth
Sometimes, a dry mouth is simply the result of not drinking enough water during the day or re-hydrating after strenuous exercise. Temporary dry mouth can also come from stress or nerves – the kind you may experience before speaking in front of a large group of people. More often, however, dry mouth is a side-effect of medication. The Academy of General Dentistry (AGD) estimates there are over 400 medications that cause dry mouth, with diuretics, pain medications, antidepressants and antihistamines among the culprits.
Chronic cases of xerostomia may be a sign of a serious health condition, such as Sjogren’s syndrome – an autoimmune disease – as well as AIDS, diabetes, cancer of the salivary glands or alcoholism. People undergoing radiation or chemotherapy for cancer frequently deal with a dry mouth over the course of their treatment.
Effects of Low Saliva
Not only does the saliva in your mouth start the process of digestion, but it helps to wash bacteria and food particles off your teeth and neutralize the harmful acids that come with it. Without this natural defence, plaque and bacteria can build up quickly at the base of your teeth, making you more susceptible to bad breath, tooth decay and gum disease. You also lose saliva’s ability to help repair and remineralize weak tooth enamel.
The American Dental Association (ADA) suggests dry mouth can lead to oral candidiasis, a fungal infection sometimes referred to as thrush. Sufferers of constant dry mouth are also prone to an uncomfortable condition called burning mouth syndrome. Insufficient saliva can interfere with the ability to taste and make wearing dentures difficult, as well.
Wetting Your Whistle
Whether your dry mouth is temporary or recurring, you’ll want to take measures to relieve the dryness in the short term. Sipping water throughout the day, chewing sugarless gum or sucking on sugar-free candy can all help moisten your mouth and stimulate your saliva glands. Besides avoiding caffeine, dry and salty foods, alcohol and cigarettes, your dentist may recommend you use an artificial saliva product depending on the status of your general health.
Preventing Dental Problems
To prevent any oral complications of dry mouth, don’t just keep your mouth as moist as possible; uphold an impeccable oral hygiene routine. Brushing at least twice a day with fluoride toothpaste and flossing daily is a must.
Depending on the severity of your dry mouth, your dentist may ultimately advise in-office fluoride treatments or sealants, which are coatings applied to the chewing surfaces of teeth to protect them against decay. Nonetheless, if you have a constant dry mouth for more than a week, see your dentist or doctor to find the source of the problem. The solution may be as simple as a change in medication, but whatever the cause, he or she can help you manage the problem and keep your mouth healthy.
