The salivary glands in the mouth are responsible to secrete saliva and keep your mouth moist and wet.

However, salivary glands may stop secreting enough saliva due to several reasons.

These include:

  • Medicines

It is highly likely that dry mouth is a side effect of certain routine medications.

Even over-the-counter medications can lead to xerostomia.

Some of the medicines like anti-depressants, pain relievers, medicines that treat anxiety, high blood pressure and muscle relaxants are the kind of medicines that can lead to a dry mouth.

Though, it can also be a side effect of prescription drugs for conditions such as Parkinson’s disease and asthma.

  • Old Age

Your mouth can become drier as you age and its contributing factor is also medication.

However, other factors such as chronic health problems, improper nutrition and the body’s inability to process medicines adequately also lead to xerostomia.

  • Smoking and Alcohol

Any tobacco product can cause dry mouth including smoking. So even if you chew on tobacco or beetle nuts or smoke you are at risk of getting this condition.

Drinking alcohol as well can increase and lead to the symptoms of dry symptoms.

  • Radiation and Chemotherapy

Cancer is a terrible disease but its therapy can also lead to certain other issues in the body such as the dry mouth.

If you get radiation therapy for the head and neck area, then it may damage the salivary glands.

As a result, the saliva production will stop and you will see a drastic drop in your saliva.

However, this can be temporary if your radiation dose is not high but in some cases, it can also be permanent depending on your treatment area.

Chemotherapy treatment and drugs can decrease saliva production as well as the nature of the saliva.

However, this can also be temporary and as the treatment concludes your saliva levels can get back to normal.

  • Health problems

This condition is not only a side effect of medicines but can also stem as a side effect of the medical health problem itself.

Conditions such as Alzheimer’s disease, HIV Aids,  diabetes, stroke and autoimmune diseases such as Sjögren’s syndrome lead to a dry mouth.

Moreover, if you have any nerve injury or nerve damage, it can result in less production of saliva.

  • Drugs

We are not talking about medicines but recreational drugs.

Methamphetamine and marijuana can lead to damage inside the mouth plus teeth and dry mouth.

Hence, if you take recreational drugs then you may be susceptible to this condition.

  • Sleeping position

If you sleep with your mouth open or snore then you are also likely to have a dry mouth at night and bad breath when you wake up.

  • Dehydration

If you are frequently dehydrated and are undergoing conditions such as fever, diarrhea and burns in the mouth then you are prone to this condition.

These are the reasons why you may get a dry mouth however, these can also lead to severe complications.

Complications-Why Do You Need to Cure it?

If you do not treat your condition on time then it can further lead to a few problems.

Untreated xerostomia eventually causes cavities, gingivitis and plaque.

It will also interfere with your ability to swallow, eat and chew.

Moreover, you may develop mouth sores, as well as cracked sides of the mouth and lips.

Some people may also get a yeast infection and thrush if the xerostomia persists.

All of this will affect your ability to eat well and you may have poor nutrition while you have this condition.

Hence, you will have to treat it either with remedies or medical treatment.
