What produces Excessive saliva?

Causes

By Mayo Clinic staff

Excessive saliva can be caused by either an increase in your body’s production of saliva or a decrease in your ability to swallow or keep saliva in your mouth.

Causes of increased saliva production

  • Dentures that are new or don’t fit well
  • GERD (Gastroesophageal reflux disease)
  • Infection in your mouth or throat
  • Medications, such as clonazepam (Klonopin), clozapine (Clozaril, Fazaclo ODT), pilocarpine (Salagen) and carbidopa-levodopa (Parcopa, Sinemet)
  • Pregnancy
  • Stomatitis (an inflammation of mucous membranes in your mouth)

Rarer causes of increased saliva production include:

  • Arsenic poisoning
  • Bell’s palsy (a condition that causes facial muscle weakness or paralysis)
  • Esophageal atresia (a disorder present at birth in which the esophagus doesn’t develop properly)
  • Mercury poisoning
  • Rabies (a deadly virus spread to people from the saliva of infected animals)
  • Syphilis (a bacterial infection usually spread by sexual contact)
  • Tuberculosis (an infectious disease that affects your lungs)

Causes of a decreased ability to swallow or to retain saliva in your mouth

Conditions that affect your muscle coordination or the function of your oral cavity also may decrease your ability to swallow or to retain saliva in your mouth. These conditions include:

 

 

An increase in the amount of saliva in the mouth is a temporary problem and is usually not a cause for concern. Under normal circumstances, about 1 to 2 liters of saliva are produced by the salivary glands every day. We are usually aware of how we are constantly and unconsciously swallowing. If there is an excessive amount of saliva in the mouth, could mean that the salivary glands produce more saliva than normal. It is a condition known as sialorrhea. It could also mean that you can swallow less than usual.

The causes excess production of saliva

Taking certain medications may result in excess of saliva in the mouth. This condition is common during pregnancy, especially during the first quarter. A swallow may also contribute to a buildup of excess saliva in the mouth. These Swallowing problems may result in damage to nerves or muscles of the throat and mouth. Other causes of excessive saliva production include the use of new dentures or those that do not fit properly to infections of the mouth, GERD or reflux, stomatitis with inflames the mucous membranes of the mouth and childhood diseases. There are also some other causes of increased saliva. These cases are rare and are arsenic poisoning, mercury poisoning, esophageal atresia, a birth defect characterized by underdevelopment of the esophagus, Bell’s palsy, syphilis, tuberculosis and rabies. Factors contributing to swallow a person’s ability to affect the saliva include allergies, acute or chronic sinusitis, polyps and tumors in the vicinity swollen lip or tongue. If the coordination and functioning of the muscles in the oral cavity are affected, could lead to a decreased ability to swallow saliva.

Home Remedies for excessive salivation

Excess saliva in the mouth can be reduced by sucking on a lemon slice. This is known to regulate the amount of saliva in the mouth. Avoid eating too many sugary foods as sugar promotes increased production of saliva. The excess saliva can be absorbed by placing a pinch of ground coffee under the tongue. Another good remedy for excessive saliva in the mouth is sucking on a few sunflower seeds. This is also a benefit of repairing salivation during pregnancy. If this situation persists for a longer period of time or worsened is recommended that a medical examination because it may indicate a problem within the salivary glands suffer.

 

Possible causes of execessive saliva (please see your doctor about this):

–Seasonal allergies/flu

—-NEW DENTAL FILLINGS / DENTURES / ANYTHING PUT IN YOUR MOUTH BY DENTIST
Alzheimer’s Disease
Bell’s Palsy
Cyclic vomiting syndrome
Epiglotitis
Grand mal seizures
Motion sickness
Mouth conditions
Parkinson’s Disease
Pregnancy
Rabies
Sjogren’s Syndrome
Stroke
Wilson’s Disease

Excess saliva is also made when there is a problem in the mouth, such as an infection. People who read mystery novels know that too much saliva may be a sign of poisoning. Many poisons, including some mushrooms, arsenic and mercury, can cause too much saliva. Medications such as pilocarpine (used to treat glaucoma and other eye problems) occasionally can cause this as well.

Sometimes, people make a normal amount of saliva but have a problem swallowing it. Infections such as strep throat, a throat abscess or the mumps can make swallowing difficult. Certain neurological diseases like Parkinson’s or stroke can do the same thing. People with these diseases often drool or dribble. Sometimes, a person who has a dental problem or an injury to the bones of the jaw will have trouble swallowing saliva.

Excessive saliva is usually a temporary problem and rarely a cause for concern but causes of increased saliva production include:

-Pregnancy
-New dentures
-Inflammation of membranes in the mouth
-A side effect of certain medications
-Or damage to the nerves that control the salivary glands

You should consult your doctor or dentist if you’re very concerned about it.

u have eaten like rice,or cabbage or other veg tables and this normally happens.So the best thing known is a soup or Curry made from fresh ginger.Take some fresh ginger peel it if you want or just wash it carefully then finely chopped and make Aesop and put black peppers and onions and other spaces.Drink it like a soup.Or have Gingery tea.Fresh Ginger will be better.Or put ginger powder in your tea.Eat a sandwich with ginger and garlic chutney.Add some chillies greens in your food and this will cure.Do not eat boiled potatoes,cabbage or boiled vegetables.If u do need just toast them with butter and add spices.

Are you eating anything with MSG or aspartame in it?

sometimes if you drink really strong coffee it causes it.

Almost any problem in the mouth, from dental decay to ulcers to tonsillitis can increase the amount of saliva produced. Another big stimulus to saliva production is our brains. We only have to think about or smell food to get the juices flowing. Other psychological factors which affect our brain, from anxiety to excitement, can alter the flow of saliva.

Excessive saliva not necessarily a problem

However, increased saliva production is usually temporary and rarely causes difficulties. We make and swallow up to two litres of saliva every day, but barely notice its passing! Making more saliva doesn’t make much difference unless there are problems swallowing it.

If you can’t swallow saliva very easily, because of a sore throat or mechanical problems, such as in cerebral palsy or Parkinson’s disease (both relatively rare), you end up drooling. This is embarrassing, messy and can make the skin around your lips and mouth sore because it contains the digestive enzyme amylase.

But I suspect that you have a different problem. You may simply have very powerful reflexes in your salivary ducts which squirt out a normal amount of saliva in a large jet from one of the several salivary glands around the inside of the mouth. The opening of one of these ducts may simply be pointing out of your mouth.

Occasionally a small stone may block or partially block one of the salivary ducts, which can cause a backlog of pressure and increased force behind the contractions to eject the saliva.

Drug treatment may have side effects

Some treatments, which include the drug atropine, can be used to reduce the flow of saliva. Although these may help in extreme drooling, they aren’t very effective and have undesirable side effects which may get in the way of the saliva’s important functions.

Saliva plays an important part in tasting food, digesting it and cleaning the mouth afterwards. It helps to lubricate the mouth for speech, keep the teeth strong and healthy, and is an important defence against bacteria and other infections. When the flow of saliva dries up, as it does in several conditions including some of the changes of ageing, these normal functions can be severely disrupted.

Simpler solutions may be better. First get your dentist or doctor to check your mouth for any cause of excess saliva production, or a stone in the ducts. Then you may need to change your eating habits a little. Try not to talk and eat at the same time (just what our parents always taught us!) and try to talk without opening your mouth too wide or lifting your tongue (some of the largest salivary ducts open under the tongue).
