Drooling while sleeping: Is it normal?
Drooling while sleeping is relatively common and is usually nothing to worry about. However, excessive drooling may indicate an underlying medical or sleep-related condition.
Causes of Drooling While Sleeping
Drooling occurs when excess saliva flows out of your mouth involuntarily. During sleep, it is common for some of the saliva produced to escape the mouth, especially if you sleep on your side or stomach with your mouth open. In these positions, gravity can cause saliva to flow out of the mouth, leading to drooling.
In some cases, drooling during sleep may be a symptom of certain health conditions, such as:
- Infections or allergies: Conditions such as a cold, strep throat, or seasonal allergies can inflame the sinuses and block airways, leading to mouth breathing and increased drooling.
- Gastroesophageal Reflux Disease (GERD): Heartburn is a common sign of GERD, but it can also cause drooling and difficulty swallowing.
- Obstructive Sleep Apnea (OSA): This sleep-related breathing disorder causes temporary pauses in breathing and can lead to mouth breathing and increased drooling.
- Neurological disorders: Conditions such as cerebral palsy or Parkinson's disease can affect nerve and muscle control, making it harder to prevent drooling.
- Other factors: Pregnancy, certain medications, and pesticide poisoning have also been linked to increased drooling.
Managing Drooling While Sleeping
If you are concerned about drooling while sleeping, there are a few strategies you can try:
- Change sleep position: Sleeping on your back can help minimize drooling as gravity keeps the saliva in your mouth.
- Treat allergies: Addressing allergies can help reduce mouth breathing and drooling.
- Seek treatment for sleep apnea: If you suspect OSA, consult a healthcare professional for treatment options such as oral appliance therapy or CPAP therapy.
- Speech therapy: This can improve jaw stability, tongue strength, and lip closure, helping to reduce drooling.
- Medication: In some cases, medications like scopolamine, glycopyrrolate, or atropine sulfate can be prescribed to reduce excess saliva production.
- Botox injections: Botox injected into the salivary glands can paralyze the muscles and temporarily prevent their function, reducing drooling.
- Surgery: In severe cases of drooling due to neurological conditions, surgery to remove salivary glands may be considered as a last resort.
While occasional drooling during sleep is common, if you experience excessive or frequent drooling, it is important to consult a healthcare professional for guidance and to rule out any underlying medical conditions.

What causes drooling while sleeping?
Drooling while sleeping is a common occurrence that can result from various factors, ranging from sleeping positions to underlying medical conditions. While occasional drooling during sleep is normal and may not require treatment, excessive and frequent drooling can signal an issue that warrants attention and evaluation by a healthcare professional.
One of the primary causes of drooling while sleeping is the sleeping position. Sleeping on your side or stomach can increase the likelihood of drooling due to gravity pulling the saliva from your mouth if it is open. Changing your sleep position by sleeping on your back may help minimize drooling. Additionally, using mouth tape or specific pillows designed for back sleepers can also reduce drooling.
Allergies, infections, and respiratory conditions can also contribute to drooling while sleeping. Conditions such as colds, strep throat, and seasonal allergies can inflame the sinuses and block airways, leading to mouth breathing and increased drooling. Treating allergies and managing infections can help reduce drooling.
Certain medical conditions, such as gastroesophageal reflux disease (GERD), obstructive sleep apnea (OSA), and neurological disorders, are also associated with drooling. GERD can cause heartburn, dysphagia (difficulty swallowing), and acid reflux, all of which can lead to increased saliva production and drooling. OSA, a sleep-related breathing disorder, can cause temporary pauses in breathing, resulting in mouth breathing and drooling. Neurological conditions, such as cerebral palsy and Parkinson's disease, can affect muscle control around the mouth and swallowing, leading to excessive drooling.
Excessive drooling can have negative medical and psychosocial effects if left untreated. Simple solutions, lifestyle changes, speech therapy, medication, and, in severe cases, surgery may be recommended to manage chronic drooling. It is important to consult a healthcare professional if you experience continuous or excessive drooling to determine the underlying cause and receive appropriate treatment.

Treatments for drooling while sleeping
Drooling during sleep is a common occurrence and does not always require treatment. However, if you believe you drool excessively, there are several strategies you can try to manage or stop drooling in your sleep. Here are some treatments to consider:
Sleep Position
Changing your sleep position can significantly impact drooling. Sleeping on your back allows gravity to keep saliva in your mouth or throat, reducing the likelihood of drooling. If you sleep on your side or stomach, switching to your back may help minimize drooling. You may need to adjust your pillow to sleep comfortably in this new position. Additionally, placing extra pillows along your body can help you stay on your back throughout the night.
Mouth Breathing and Allergies
If you sleep with your mouth open, you are more likely to drool. Focusing on breathing through your nose and keeping your mouth closed while sleeping can reduce drooling. Conditions like colds, strep throat, or allergies can block your airways, causing you to breathe through your mouth. Treating allergies and managing these conditions can help reduce mouth breathing and subsequent drooling.
Medications
Certain medications can help reduce excess saliva production. For example, scopolamine, glycopyrrolate, and atropine sulfate are options that your healthcare provider may recommend. These medications can be delivered in various forms, such as patches placed behind the ear, to help manage drooling.
Botox Injections
Botulinum toxin (Botox) injections are considered a safe and effective treatment for excessive drooling, especially in individuals with neurological disorders. Botox is injected into the salivary glands, paralyzing the muscles and preventing them from producing saliva. The effects typically last about six months, and repeat injections may be needed.
Speech Therapy
Speech therapy can help improve jaw stability, tongue strength, and mobility, aiding in better lip closure. This therapy can take time but teaches techniques to improve swallowing and decrease drooling.
Surgery
In severe cases of drooling where other treatments have been ineffective, surgery may be recommended as a last resort. Surgical methods involve removing the sublingual or submandibular salivary glands to reduce saliva production.
It is important to consult a healthcare professional if you experience continuous or excessive drooling to determine the underlying cause and discuss the most suitable treatment options for your specific situation.

Potential health complications from drooling while sleeping
While drooling during sleep is normal and does not always require treatment, excessive drooling can indicate underlying health issues and may lead to negative medical and psychosocial effects if left untreated.
Infection
Excess saliva can be aspirated into the lungs, causing pneumonia. Drooling can also be a sign of other infections, such as sinus infections, tooth infections, or soft tissue infections in the mouth.
Neurological conditions
Neurological disorders can affect the nerves and muscles that control swallowing, leading to poor control over the muscles around the mouth and increased drooling. Examples include cerebral palsy, Parkinson's disease, and amyotrophic lateral sclerosis (ALS).
Obstructive sleep apnea (OSA)
OSA is a sleep-related breathing disorder that causes temporary pauses in breathing during sleep. People with OSA may experience an irritated or obstructed oesophagus, leading to increased saliva production and drooling.
Gastroesophageal reflux disease (GERD)
People with GERD may feel like there is a lump in their throat, which can cause them to drool more frequently.
Allergies
Allergies can lead to increased saliva production and a stuffy nose, causing mouth breathing and increased drooling.
Dehydration
Drooling can lead to dehydration, as the body loses fluids during sleep.
If you experience frequent and excessive drooling during sleep, it is important to consult a healthcare professional for guidance and to determine the underlying cause.
