Having a dry mouth is not so easy. People who have dry mouth face many difficulties like difficulty in swallowing, problem in speaking, sore throat, poor oral health, etc.

Although, it is not so easy to get rid of dry mouth, however, the following steps can help you in getting relief from your dry mouth symptoms:

  • Use a mixture of warm water and salt for washing your mouth before sleeping as it will reduce the acidity in your mouth and help you in getting relief from dry mouth
  • Prefer nasal breathing rather than breathing through your mouth. Mouth breathing evaporates the moisture from your mouth resulting in dryness of oral cavity which in turn causes dry mouth and also exacerbates the problem
  • Avoid environmental conditions that may result in dry mouth. Use air filters, humidifiers, or other appliances that may moisten the air at your home.
  • Avoid dryness of your lips as it may contribute to dry  mouth
  • Drink water between the meals so that you can swallow your food easily

Treatment of Dry Mouth

The treatment of dry mouth is usually based upon its underlying cause. The treatment mainly focuses on the following three areas:

  • Managing the medical conditions responsible for causing the dry mouth
  • Preventing tooth decay
  • Stimulating the flow of saliva, if possible

Managing the Medical Condition

If the dry mouth is caused due to some medication, the doctor may change the medicines. However, in some cases, where changing the medication is not possible (e.g., chemotherapy), the doctor focuses on increasing the flow of saliva.

Preventing Tooth Decay

Lack of saliva not only interferes with your swallowing of food but also makes your teeth prone to various dental infections including decaying of teeth. Tooth decay increases the symptoms of dry mouth, therefore treating tooth decay can somehow control your symptoms of dry mouth.


Following steps can be taken for avoiding the tooth decay:

  • Brushing your teeth daily, preferably after the meals
  • Flossing your teeth
  • Using fluoride-containing toothpaste
  • Frequent dental check-ups

Increasing the Flow of Saliva

For increasing the flow of saliva, your doctor may suggest the use of artificial salivary products. Besides, some mouthwashes and toothpastes are also specially made for dry mouth and therefore increase the flow of saliva in the mouth.

Besides the above-mentioned steps for treating the dry mouth, some other treatment methods are:

Preserving the Saliva

People suffering from dry mouth should keep their oral tissues as moist as possible for preserving the remaining saliva. This can be done in following ways:

  • Avoid mouth breathing
  • Avoid using OTC antihistamines or decongestants because they make the mouth dry
  • Avoid drinking alcohol, consuming tobacco and its products

Saliva Substitution

This involves using substances that may replace the moisture provided by the saliva. It includes the following steps:

  • Drinking plenty of water
  • Using alcohol-free mouthwashes
  • Using mouth gels
  • Using OTC saliva substitutes and oral lubricants containing glycerin
  • Moisturizing your lips

Saliva Stimulation

This step involves stimulating the salivary glands for releasing the saliva in patients whose salivary glands are still functional. It includes the following steps:

  • Chewing sugar-free gums and candies
  • Using lemon drops, lozenges, or other hard candies for saliva production
  • Stimulating saliva through medications like pilocarpine (Salagen) and cevimeline (Evoxac). However, patients with asthma or glaucoma should avoid using these medicines.

Avoiding Dental Caries and Candida Infection

Patients with dry mouth may suffer from cavities, gingivitis, periodontal disease, and fungal infections. All these diseases worsen the symptoms of dry mouth and hence should be avoided. This can be done in the following ways:

  • Having a diet low in sugar content
  • Using toothpaste rich in fluoride, calcium, and phosphate which helps in teeth remineralization for preventing the cavities
  • Using antifungal medications in case of fungal oral diseases like oral candidiasis and thrush

Frequently Asked Questions

Besides, chewing sugar free gums and candies, sucking on lemon and having tart foods may also be helpful as they help in stimulating the flow of saliva from your salivary glands which keeps your mouth moist and therefore prevents the dry mouth.
