Dry Mouth
A dry mouth is called xerostomia when insufficient or no saliva flow. Although xerostomia is not a disease, it can be a symptom of several medical conditions, a side effect of radiation to the neck and head, or several medications. It can or can not be associated with diminished function of the salivary glands. About 20% of the elderly suffer from xerostomia, a common complaint that affects many people. However, xerostomia does not appear to be related to age itself, unlike the potential for the elderly to take medications that can cause xerostomia as a side effect.
The muscarinic M3 receptor mediates normal salivary function. Stimulation of this receptor results in the increased fluid flow of salivary secretions. Afferent nerve signals reach the salivatory nuclei in the medulla when the oral mucosal surface is stimulated. Nerve signals that travel outward from the brain and spinal cord (efferent signs) stimulate cells in the salivary glands (glandular epithelial cells) to produce more saliva. A chemical called acetylcholine mediates these signals. The medullary signal could potentially be impacted by inputs from the cortex, which may result from various stimuli such as taste, smell, and emotional states like anxiety or depression.
When you don’t have enough saliva (spit), you may experience dry mouth (xerostomia). The salivary glands in your mouth produce the fluid known as saliva.
Salivary glands in your mouth produce the fluid known as saliva, not an illness itself. It is often a side effect of allergies or cold medications like decongestants or antihistamines.
Xerostomia, or Dry mouth, refers to a situation in which the salivary glands within your mouth don’t make sufficient saliva to keep your mouth wet. Usually, dry mouth may be caused by a condition directly affecting the salivary glands. A dry mouth is often due to the side effect of certain medications, ageing issues, or radiation therapy for cancer.
Saliva prevents tooth decay by neutralising bacterial acids, limiting bacterial growth, and removing food particles. Additionally, saliva improves taste perception and facilitates chewing and swallowing. Additionally, saliva’s enzymes aid digestion.
A dry mouth can be a nuisance or significantly impact your general health, the health of your teeth and gums, your appetite, and your enjoyment of food if you reduce saliva production.
1 – Medications
This is one of the most common causes of dry mouth. Hundreds of medications cause dry mouth. Some more common ones are anti-depressants, sedatives, beta-blockers, high blood pressure medication, antihistamines, and cold/flu medications. Other drugs, such as tobacco and alcohol, can dry the mouth.
2 – Anxiety, Depression, or Stress
These conditions have been shown to cause dry mouth. The effective way to treat it is to find effective ways to manage your anxiety, depression, or stress.

3 – Diabetes
Some debate about whether diabetes causes dry mouth.
4 – Autoimmune Diseases
Such as Sjögren’s syndrome, HIV, and Graft-versus-Host disease. Sjögren’s syndrome causes dry mouth and dry eyes. In other immunologic diseases, it is suspected that the body’s immune system is attacking the salivary glands, thus decreasing the amount of saliva produced.
5 – Radiation treatment to the head and neck area
Radiation treatment to the head and neck area can cause damage to the salivary glands. Some glands can recover and produce saliva, usually after radiation treatment. However, the most significant salivary gland usually has trouble recovering and can be permanently damaged, leading to chronic dry mouth.
6 – Hormone changes
Hormonal changes occur with pregnancy and menopause in females. These hormonal changes have been associated with dry mouth. If you are pregnant and experiencing dry mouth, your dry mouth should resolve once your baby is born. Suppose you have a dry mouth associated with menopause. In that case, you may want to see your dentist to see what treatment is available.
7 – Side effects of certain diseases and infections
Dry mouth can affect medical conditions, including anaemia, HIV/AIDS, Alzheimer’s disease, diabetes, Sjögren’s syndrome, cystic fibrosis, rheumatoid arthritis, hypertension, Parkinson’s disease, stroke, and mumps.
8 – Nerve damage
A dry mouth can result from nerve damage to the neck and head from an injury or surgery.
9 – Dehydration
Things that lead to dehydration, such as fever, excessive sweating, vomiting, diarrhoea, blood loss, and burns, can cause dry mouth.
10 – Surgical removal of the salivary glands
11 – Lifestyle
Smoking or biting tobacco can influence how much spit you make and bother your dry mouth. Breathing with your mouth open a great deal can add to the issue.
Symptoms of Dry Mouth
Symptoms of dry mouth can include:
- A sticky tongue and mouth
- Thick saliva
- Dry throat and tongue
- Chapped lips
- Trouble chewing and swallowing
- Trouble speaking
- Trouble tasting food
- Bad breath
- Mouth sores
- Mouth infections
- Tooth decay
- Gum disease
- Burning or Tingling in the mouth or throat
A dry mouth can also affect other parts of the body. Symptoms of dry mouth in the body include:
- Dry eyes
- Weakened sense of smell
- Constipation
- Joint stiffness and pain
- Yeast infections
- Unexplained weight loss
What problems can a dry mouth cause?
Saliva plays a vital role in keeping your mouth healthy. You may also experience the following issues if you have a dry mouth:
- A decreased or altered sense of taste
- Dry lips
- Bad breath (halitosis)
- Difficulty speaking, eating or swallowing
- Tooth decay and gum disease
- Recurrent mouth infections, such as oral thrush
Maintaining good oral hygiene if you have a dry mouth is essential to reduce the risk of dental problems. You should also see a dentist regularly so that they can identify and treat any issues early on.

To relieve your dry mouth:
- To make saliva flow, chew sugar-free gum or eat sugar-free hard candies. For some people, xylitol, often found in sugar-free gum or sugar-free candies, may cause diarrhoea or cramps if consumed in large amounts.
- Alcohol-based mouthwashes can be drying, so avoid using them.
- Sip water regularly.
- Stop all tobacco use if you chew or smoke tobacco.
- Look for goods containing xylitol, such as Mouth Kote and Oasis Moisturizing Mouth Spray, carboxymethylcellulose, hydroxyethyl cellulose, and Biotene Oral Balance, when purchasing over-the-counter saliva substitutes.
- Try a mouthwash made for dry mouth, especially one with xylitol, like Biotene Dry Mouth Oral Rinse or ACT Total Care Dry Mouth Mouthwash. Both of these mouthwashes also protect teeth from decay.
- Avoid over-the-counter antihistamines and decongestants because they can worsen your symptoms.
- During the night, use a room humidifier to add moisture to the air.
- Breathe through your nose, not your mouth.
The cause of dry mouth affects how dry mouth is treated. Generally, the treatment of a dry mouth focuses on three areas:
- Preventing tooth decay
- Taking care of the medical conditions that are underlying the dry mouth
- Increasing the flow of saliva, if possible
Xerostomia is a common problem and can significantly affect a patient’s quality of life if not recognised and treated. Through proper education, prevention, assessment, referral, and appropriate treatment, patients with dentists’ help can minimise its effect on dental health xerostomia and quality of life.
