When should I be worried about drooling? A comprehensive guide

3 min read

The average adult produces 2 to 4 pints of saliva per day, but excessive or sudden changes can be concerning. While normal in infants, persistent drooling in adults can signal an underlying health issue. This guide will help you understand when should I be worried about drooling?

Quick Summary

Sudden, excessive, or persistent drooling in an adult, especially when combined with difficulty swallowing or breathing, warrants a medical evaluation to rule out serious underlying issues like neurological conditions or infections. Drooling is not considered normal past toddlerhood and can signal an underlying problem.

Key Points

  • Sudden onset: A sudden start of excessive drooling in an adult is a major red flag and should be investigated by a doctor.

  • Breathing difficulty: If drooling is paired with trouble breathing or swallowing, seek emergency medical care immediately, as it can indicate a life-threatening condition.

  • Neurological links: Drooling can be a symptom of underlying neurological disorders like Parkinson's, ALS, or post-stroke complications that affect muscle control.

  • Medication side effects: Many medications, particularly antipsychotics such as clozapine, can have hypersalivation as a known side effect.

  • Persistent in adults: Unlike in teething babies, persistent, unexplained drooling in adults is not typical and warrants a doctor's visit to determine the cause.

  • Gastrointestinal issues: Acid reflux (GERD) is a very common cause, as the body produces more saliva to neutralize stomach acid backing up into the esophagus.

The difference between normal and concerning drooling

Drooling, medically known as sialorrhea or ptyalism, is the involuntary flow of saliva from the mouth. While it is a perfectly normal part of development for infants and toddlers, particularly during teething, it should subside as a child matures and gains better muscle control around their mouth. Normal drooling in adults typically occurs during sleep and is often harmlessly related to sleeping position. However, when drooling begins suddenly, persists, or is accompanied by other symptoms, it can be a red flag that something is amiss with your health.

Common, harmless causes of drooling

Before jumping to conclusions, it's helpful to consider some of the more common and less threatening reasons for increased saliva production or poor swallowing. These issues are often temporary and resolve on their own once the cause is addressed.

  • Dietary triggers: Eating highly acidic, spicy, or sugary foods can stimulate your salivary glands.
  • Pregnancy: Hormonal changes can cause a temporary increase in drooling, known as ptyalism.
  • Dental work: New dental appliances or procedures can irritate oral tissues and affect swallowing.
  • Temporomandibular Joint (TMJ) disorders: These can make swallowing painful or difficult.

Medical conditions that can trigger excessive drooling

When drooling persists or appears without an obvious cause, it's important to consider other potential medical conditions. A medical professional can help diagnose and treat these issues.

Gastroesophageal Reflux Disease (GERD)

GERD, or chronic acid reflux, is a common cause. Stomach acid backing up can trigger increased saliva production to neutralize the acid.

Infections of the mouth and throat

Infections can inflame the mouth and throat, leading to painful swallowing and increased saliva production. Common infections include strep throat, tonsillitis, and sinus infections.

Medication side effects

Certain medications, including some antipsychotics (like clozapine), sedatives, and anti-seizure drugs, can cause hypersalivation.

Neurological conditions and drooling

Some of the most concerning causes of excessive drooling are related to neurological conditions that affect muscle control and swallowing reflexes.

Stroke

A stroke can damage the brain areas controlling swallowing and facial muscles, leading to muscle weakness and difficulty controlling saliva.

Parkinson's Disease

Drooling is common in Parkinson's disease due to impaired ability to swallow saliva effectively and maintain closed lips.

Other neurological disorders

Conditions like ALS, Cerebral Palsy, and Multiple Sclerosis can contribute to drooling due to muscle weakness and impaired coordination.

Drooling in children vs. adults: A comparison

The table below highlights the differences in the causes and significance of drooling between children and adults.

Feature Children (typically under age 3) Adults (typically age 4+)
Causes Teething, underdeveloped muscle control, infections, allergies, sleeping habits Infections, GERD, medications, neurological conditions, dental issues, toxins
Significance Normal part of development, but persistent issues need evaluation Often signals an underlying medical condition, especially if sudden or accompanied by other symptoms
Warning Signs Excessive drooling with fever, difficulty breathing, or holding the head in a strange position Sudden onset, difficulty breathing or swallowing, choking, signs of neurological impairment
Social Impact Generally accepted as normal behavior Can cause embarrassment, social stigmatization, and anxiety

When to seek immediate medical attention

Seek immediate care if excessive drooling is accompanied by difficulty swallowing, trouble breathing or choking, fever with a sore throat, changes in head position to aid breathing or swallowing, or signs of poisoning.

What to expect at the doctor

Your doctor will inquire about your symptoms and medical history and perform a physical exam. They may refer you to a specialist for further testing and treatment.

Prevention and management strategies

Treatment targets the root cause, but management strategies include improving oral hygiene, adjusting sleeping position, dietary changes, oral appliances, and medical treatments like medication or Botox injections.

For more detailed information, consult authoritative sources like the Cleveland Clinic on the causes and treatments of drooling.

Conclusion

While normal in infants, persistent or sudden excessive drooling in adults warrants medical attention. Understanding the potential causes and accompanying symptoms is key to knowing when should I be worried about drooling? Consult a healthcare provider if you have concerns, as treating the underlying condition is crucial.

Frequently Asked Questions

Excessive drooling is medically known as ptyalism or sialorrhea. It can result from either an overproduction of saliva or an impaired ability to swallow and clear it from the mouth.

Drooling during sleep is common and often related to your sleeping position. If you sleep on your side or stomach, gravity can pull saliva from your mouth. However, it can also be a sign of an issue like acid reflux.

Yes, stress and anxiety can affect the nervous system and potentially increase saliva production. Stress can also worsen underlying conditions like acid reflux that contribute to drooling.

Yes, increased drooling (ptyalism) is a known effect of hormonal changes during pregnancy and is often associated with morning sickness or heartburn. It typically subsides as the pregnancy progresses.

Yes, issues like new dentures, braces, infections (abscesses, gum disease), or jaw misalignment can irritate the mouth or affect swallowing, leading to increased saliva or drooling.

Serious warning signs include sudden onset of drooling, difficulty breathing or swallowing, choking, a persistent sore throat, or accompanying neurological symptoms. These warrant immediate medical attention.

When stomach acid backs up into the esophagus and throat, the body naturally produces more saliva to help neutralize the acid and protect the tissues. This increased saliva can lead to drooling, especially when lying down.
