What Causes Dry Mouth?

Dry mouth is an uncomfortable condition that can occur for a wide variety of reasons, including poor oral hygiene. People who suffer from dry mouth feel as though their oral cavities are full of cotton. They feel no moisture inside of their mouths, and they may even have a bad taste inside of their mouths, as well. The following are the most common reasons that a person will suffer from dry mouth:

What Causes Dry Mouth?

Oral Health Agents

Consumers use oral health products so that they can maintain fresh breath and kill bacteria. Unfortunately, some of the most common oral health agents are guilty of causing dry mouth. Any mouthwash that has alcohol, for example, will have an adverse effect on someone’s mouth that will include dryness.


Certain medications are well known for causing patients to have dry mouths. Examples of such prescriptions are antibiotics, antihistamines, antidepressants and some diuretic substances. Patients who experience dry mouth from such medications will have to drink at least eight glasses of water per day.


Sometimes, a person’s lifestyle can cause him or her to suffer from dry mouth. Alcohol use, for example, is a prime cause of dry mouth. Marijuana usage is even more likely to cause dry mouth than alcohol usage is.

Dental Procedures or Illnesses

Dry mouth can occur after dental surgery and certain dental procedures. A simple tooth extraction can cause dry mouth because the customer has to have cotton balls inside of the oral cavity. The anesthetic can cause a person to have dry mouth, as well. Sometimes the instance of dry mouth can come from a dental health condition such as gingivitis.

The Aging Process

The natural aging process can sometimes cause glands to produce less efficiently than they were producing before. Slow glandular movement can cause the mouth to become dry. Several other senior health conditions can contribute to a dry mouth experience. Radiation treatments for cancer, sleep apnea and Sjögren’s syndrome are additional conditions that can contribute to a dry oral cavity.


Women’s hormones repeatedly shift when they are carrying children. A pregnancy can cause a woman to have a dry mouth as well as a depressed or irritable disposition.

What to Do if You Experience Dry Mouth

Anyone who experiences dry mouth that causes life restricting problems should contact a dentist or specialist to examine the symptoms. In the meantime, increasing water intake, chewing on gum and eating a good portion of vegetables can help to stimulate the salivary glands.
