Dry mouth causes can be divided into several main groups. But before we talk about the causes of dry mouth and dry tongue, let's take a look at what we are talking about!
A dry mouth is basically a lack of saliva.
It may be a relatively mild condition, where the flow of saliva is less than normal and results in a general sense of your mouth being a bit dry.
Or it can be much more severe, where there is hardly any saliva being produced at all, resulting in other dental problems.
What other symptoms of dry mouth are there?
What problems can a lack of saliva cause? Apart from the sheer discomfort that a dry mouth causes, there are a number of other things which can be serious.
Without the lubrication qualities of saliva, a dry mouth causes a general soreness around the mouth and on the tongue. Your mouth starts to get "gummed up", and your dry tongue tends to stick to the roof of your mouth.
But saliva does more than just lubricate. It also neutralizes acids from things we eat and drink, and also acids from plaque on our teeth. Without saliva, these acids are not neutralized, and this leads to more tooth decay than normal. You start to get more cavities appearing.
Saliva also helps to keep the balance of bacteria in our mouths. It helps to protect against gum disease. Without saliva, any gum problems you already have are likely to get worse.
Even if you don't have any teeth and wear full dentures, a dry mouth causes problems. Saliva provides a degree of lubrication for dentures, and also helps them to stay in place. If you have a dry mouth, your dentures will not stay in place as well as normal, and will tend to rub on the gums, causing Denture Pain.
There are several causes of dry mouth, which is also called xerostomia. Among the most common dry mouth causes, taking medication is the number one.
A very common side effect of many, many medications is a reduction in the flow of saliva. Less saliva leads to a dry mouth and a dry tongue. This is the case for both prescription and non-prescription drugs.
The most common medications involved in dry mouth causes are drugs used to treat anxiety, depression, and allergies. Cold cure remedies which contain decongestants and antihistamines will also reduce saliva flow.
The list of drugs goes on, and includes Accutane for acne, some drugs used for epilepsy, as well as some drugs for high blood pressure. A dry mouth can also be caused by certain types of sedative.
This discomfort and swelling is caused by saliva building up behind the blockage, creating pressure in the duct, usually when you're getting ready to eat.
The problem is usually worse when you breath through your mouth at night, particularly if you live in a climate with dry air, or you have heating or air conditioning that dries out the air in your home. USING A ROOM HUMIDIFIER can really help.
Modern radiotherapy techniques limit the radiation exposure as far as possible, but sometimes a group of salivary glands near the tumor will be affected to a degree

Some people only get a dry mouth when they are asleep. During the day they don't have any problems, but at night time somethings happens that results in them waking up with a dry mouth. For more detail on this, visit my page about a Dry Mouth at Night.
As you can see, dry mouth causes are many and varied! But by far the most common one among all the causes of dry mouth and dry tongue is medication prescribed by a doctor. Sometimes it's possible to adjust the dose of your medication to help reduce the degree of dry mouth. So if you are having problems with a dry mouth, and you are on medications, you first port of call should be your doctor!
