Dry Mouth: Causes, Effects, And Prevention

Xerostomia is another name for dry mouth. It happens when your mouth’s salivary glands don’t create enough saliva. Your mouth will feel parched or dry as a result of this disease. Additionally, it may result in symptoms like cracked lips, poor breath, and a dry throat.

Your digestive system needs saliva to function properly. Your meal gets moistened and broken down with its aid. Additionally, it serves as an important defense mechanism for your body to maintain good oral health, shielding your mouth from tooth decay and gum disease.

On its own, dry mouth is not a major medical condition. It can be easily avoided with regular dental preventive care services. However, it might occasionally be a sign of a different illness that needs medical attention. Additionally, issues like tooth decay and ulcers in the mouth may result.

What are the causes of dry mouth?

Numerous factors can contribute to dry mouth. Furthermore, simply having a dry mouth does not always indicate an underlying disease.

It’s crucial to discuss diagnosis and treatment options with your doctor if you suspect a different ailment is to blame or if you experience additional symptoms.

Below are the possible causes of dry mouth include:


When you lose too much fluid without replacing it, you get dehydrated. This may occur as a result of nausea, diarrhea, profuse perspiration, or blood loss. Your body doesn’t create as much saliva when you’re dehydrated, which can make your mouth feel dry.


Many different kinds of drugs may have a side effect called dry mouth. Some of the most popular drug classes that have been linked to dry mouth include those used to treat depression, anxiety, diarrhea, high blood pressure, and asthma. Diuretics, some chemotherapeutic drugs, and antihistamines can all decrease salivation. Before discontinuing any medications that you believe may be causing mouth dryness, it’s crucial to consult your doctor.

Radiation therapy

The side effect of radiation therapy on the head or neck frequently causes dry mouth. Radiation affects the salivary glands, which results in less saliva output.

Stress and anxiety

When you’re anxious or agitated, your body makes extra cortisol, sometimes known as the “stress hormone.” Your saliva’s composition can change as cortisol levels rise, which can leave your mouth feeling dry.


As you age, dry mouth is a normal occurrence. This can be the result of medical conditions, particular prescriptions, or adjustments in how well your body can process the medicines you take.

Mouth breathing and snoring

The saliva in your mouth evaporates when you breathe through it. Similarly, disruptive snoring can occur when your mouth is open. This can make your mouth dry or make it much dryer already.

Smoking and recreational drug use

Saliva production can be decreased by cannabis and tobacco smoking. Another side effect of using methamphetamines is a very dry mouth.

The Side Effects Of Dry Mouth

A sticky or parched sensation develops in the mouth when one has a dry mouth. Other typical signs include:

  • difficulty swallowing, chewing or talking
  • burning sensation in your mouth
  • trouble tasting food or drinks
  • dry tongue
  • cracked lips
  • mouth sores
  • dry throat
  • bad breath

Treatments For Dry Mouth

Treatment for dry mouth relies on a number of variables, including if the patient has an underlying disease or condition and whether they are taking any medications that might be contributing to their dry mouth.
If an underlying reason is identified, certain actions can be taken to lessen its impact.


The doctor will either change the dosage or prescribe another prescription that is less likely to induce dry mouth if a certain medication is suspected of being the cause.

Stimulating saliva production

To increase salivation, a doctor may prescribe drugs like pilocarpine (Salagen) or cevimeline (Evoxac).
Treatment for dry mouth symptoms normally focuses on four areas.

  • boosting saliva production
  • restoring missing secretions
  • preventing dental caries
  • adopting certain actions, including treating infections

A person who has a dry mouth should take extra care with their oral and dental hygiene. Regular tooth brushing and flossing are crucial. Plaque removal and treatment are additional crucial measures.

  • gum infections
  • inflammation
  • decay in the teeth

Tips To Prevent Dry Mouth

  • Regularly drinking water will keep your mouth moist.
  • Drinking milk or water with meals adds moisture and facilitates swallowing and chewing.
  • Sleep in a humidified space. In the morning, you might feel better.
  • Avoid liquids that are acidic, caffeinated, or sweet.
  • Visit the Plano dentist for routine cleanings and examinations.
