Drooling during sleep is generally not a medical issue. In fact, many people experience it, although it can be embarrassing, especially if you nap in public or at a friend’s house.
Sometimes, drooling can signify underlying health concerns that need a doctor’s attention. Here, we discuss potential reasons for night drooling, measures you can take, and how to determine when a doctor’s visit is warranted.
10 Common Causes of Drooling During Sleep
There are numerous reasons for drooling in your sleep. Some individuals only drool during quick naps, while others are accustomed to waking up to a damp pillow. Many cases are harmless, but certain health issues could be at play, necessitating a medical opinion. Here are 10 typical explanations for drooling at night.
1. Sleep Position

During rest, your mouth generates additional saliva for oral health support, while your body, including facial muscles, relaxes. If you lie on your side or stomach, saliva can escape, especially if nasal congestion forces mouth breathing. This can be a reason for drooling, particularly when you have allergies or a cold.
2. Medication Side Effects

Certain medications like sedatives, some antipsychotics, and even a few antibiotics are known to induce drooling. Remarkably, some NSAIDs such as ibuprofen might have the same effect. Rather than stopping your medication, consult your physician if drooling bothers you. They may adjust your treatment or explore alternatives.
3. Nasal Congestion
As discussed, a blocked nose forces you to keep your mouth open while sleeping. This congestion can arise from colds, allergies, and other causes. Medications for allergy relief and nasal decongestion are available, but consult your doctor before trying them. Since these situations are temporary, the drooling will likely stop once your congestion resolves.
4. Deviated Septum
A misaligned nasal septum might hinder airflow, prompting mouth breathing and possible drooling during sleep. The septum is the cartilage barrier dividing the nasal chambers. Any misalignment can lead to breathing problems, particularly overnight. Surgical fixes exist; however, consultation with healthcare professionals is vital to determine the appropriateness of surgery.
5. Sleep Apnea
Sleep apnea leads to intermittent breathing pauses during rest, often causing drooling. Diagnosis usually requires professional evaluation as symptoms include loud snoring and choking sounds. Compromised sleep due to apnea affects both the sufferer and household members. Medical advice should be sought on available treatments.
6. Infection or Dental Issues

Oral infections or dental problems can over-stimulate saliva production, resulting in drooling. Infections might be accompanied by pain during eating, speech, or even swollen gums and bleeding when brushing. Visiting a dentist or doctor promptly is crucial for treatment.
7. Gastroesophageal Reflux Disease (GERD)
GERD frequently causes acid reflux, or heartburn, and might also prompt excess saliva and drooling. Difficulty swallowing (dysphagia) related to GERD can exacerbate this. If heartburn is frequent, discussing management options with a medical professional is advisable.
8. Neurological Conditions
Neurological disorders like strokes, Parkinson’s, Alzheimer’s, Huntington’s disease, Bell’s Palsy, and others can lead to excessive drooling. Interestingly, a vitamin B12 deficiency might also be involved due to its impact on neurological health, potentially causing salivation problems.
9. Teeth Grinding

Nocturnal grinding or the use of mandibular devices can encourage drooling. It’s essential not to discontinue use of night guards due to drooling concerns. Professional advice can assist with managing drooling effectively.
10. Pregnancy
Pregnancy-related excessive salivation, known as ptyalism gravidarum, can increase drooling. Stress, changes in sleep patterns, and physical discomfort might all contribute to this during pregnancy.
