    Drooling occurs when a person's saliva leaks out of their mouth without their knowledge. Humans have six salivary glands, and drooling occurs when these glands are overworked.

    Babies typically drool a lot. Drooling is a common problem for infants beginning at around the third month. Babies vary in how much they drool.

    An infant that drools excessively may have either weak jaw muscles or an overabundance of saliva.

    Drooling is a normal component of a baby's physical growth, so don't worry.

    Drooling: What Is It?

    Drooling is the inadvertent loss of saliva via the mouth. Too much saliva or a lack of oral muscular strength are common causes.

    Salivary glands are those in the body that are responsible for saliva production. Six among these glands can be found in and around your cheeks, bottom gums, and front teeth.

    Usually, these glands consume two to four pints' worth of saliva daily. Drooling can occur if these glands produce an excessive amount of saliva.

    It's normal to drool a bit while you're sleeping.

    People with cerebral palsy and other neurological disorders are at increased risk of drooling.

    Why Do I Keep Drooling?

    Drooling can indicate a health problem, a delay in development, or the side effect of a drug.

    Drooling can be caused by a variety of issues, including those that increase saliva production, make swallowing difficult, or weaken the muscles used to govern facial expressions.


    As newborns become more active, drooling increases from birth onwards, reaching a peak between the ages of three and six months. For example, this is to be expected throughout the teething phase.


    An overabundance of saliva is a common side effect of eating an acidic diet.


    Although most babies do not have their first tooth until they are between 6 and 8 months old, the teething process actually starts far earlier than that. This is why some babies start drool as early as 3 months. When a tooth first begins to break through the gums, there is an increase in saliva production, and your baby may drool excessively.


    Drooling is common in infants who tend to leave their mouths open for long periods of time. Your child may drool if he has a stuffy nose or just has the habit of keeping his lips open for long periods of time.

    Capable of Maintaining Attention for a Significant Amount of Time

    Young children and infants benefit cognitively from focused attention. After being stimulated, salivation increases by a factor of six. Babies can't properly swallow all that saliva till later on. And because their concentration is elsewhere while they are focused on a task, their mouths and tongues drool.


    Saliva is produced by glands in the mouth in reaction to the flavour of food. The mouth produces more saliva in response to sour or spicy foods. Your child may drool more than usual after eating spicy meals or citrous fruits like oranges, limes, or grapefruits.

    Insufficiencies in the Nervous System

    Excessive drooling and salivation are common signs of many neurological diseases. Bell's palsy is an injury to the facial nerve that causes temporary weakness in one side of the face.

    Drooling can be a symptom of neurological disorders that disrupt muscle coordination, such as cerebral palsy, Bell's palsy, and Wilson's disease. These conditions make swallowing difficult, cause saliva to pool in the mouth, and alter the usual position of the lips.

    Drooling is more likely to occur when you have a medical condition that makes it difficult to regulate your facial muscles, such as Parkinson's disease. Muscle weakness can make it difficult to seal the lip and swallow saliva, which can be a symptom of a number of neurological disorders.

    Pharmacological Adverse Effects

    An increase in saliva production has been linked to the use of some medications, including those used to treat sleep disorders, alleviate pain, and treat eye infections in children and even in breastfeeding mothers.

    Hypersalivation, the source of heavy metal poisoning-related baby drooling, is another possible complication.

    Assorted Other Disorders

    The presence of an excessive amount of digestive juices is often the root cause of drooling. Saliva production can also be boosted by pregnancy and medical problems like acid reflux.

    Problems with swallowing can be brought on by a number of different conditions, including allergies, tumours, and infections in the head and neck region like strep throat, tonsillitis, and sinusitis.

    Is Drooling Common in Babies?

    A baby's first two years of life are often marked by excessive drooling, a common developmental trait. Drooling is common for infants, even when they are sleeping, because they do not yet have full control over the muscles of their mouth and the function of swallowing. You can count on your baby's drooling to last until he is 18 to 24 months old.

    When your baby is teething, drooling is inevitable, so plan on changing his or her clothes several times a day. As a matter of fact, drooling is a relatively normal baby behaviour. Except when it continues past the age of four, drooling in children is not typical.

    Drooling in Babies Between 1 and 24 Months of Age

    Babies drooling is normal and beneficial to their growth. However, there are times in a baby's development and growth when his drooling becomes excessive. A newborn might not saliva at all between the ages of one and three months. Since a newborn is always facing up at this point, drooling is uncommon. Thus, he might not drool now or ever again. Nonetheless, drooling can begin as early as three months of age for certain infants.

    Why Do Babies Drool So Much?

    Excessive drooling is defined as the uncontrollable flow of saliva from the mouth of a baby who is older than the typical drooler's age.

    After the age of two, excessive drooling in a child warrants a trip to the doctor.

    Excessive drooling occurs when the mouth and tongue are not coordinated, despite the common belief that this is due to an excess of saliva. Poor swallowing may come from this inability to coordinate muscle movements.

    What Causes My Toddler's Constant Drooling?

    Toddlers' excessive drooling is a common source of consternation for parents, especially when the child looks to have most or all of his or her permanent teeth already. But don't worry; drooling is normal for kids before they learn to control the muscles in their face.

    Children develop this mastery in part because they are able to sense the moisture surrounding their mouth and chin, swallow often to prevent excess saliva from building up, seal their lips, and manage their saliva's suction. When you consider all that needs to be done to stop drooling, you'll see that this is a quite extensive process. Its typically occurs at age two, but delays in this development are not seen as an issue until until age four.

    There are several functions for saliva, such as:

    • Helps with digestion, lubricates the mouth for eating, swallowing, and speaking, and prevents dental cavities by buffering acids in the mouth.

    However, this overproduction of saliva can result in a persistently moist mouth and chin, which can cause skin irritations and even infections, as well as dampness and stains of clothing, which can be embarrassing as the child grows. Delays in this process may be seen in children with neurologic deficits.

    Abnormal oral sensitivity, as well as delay in muscle control, may account for excessive drool in an otherwise normally growing infant. Rarely, it might be caused by an overabundance of saliva. Oral infections, nasal blockages, and drugs are among other potential causes.

    Chronic excessive drooling affects roughly 0.6% of the population. Keeping absorbent bibs or wristband on your toddler may be necessary to deal with the excessive drooling.

    Some infants and toddlers may not realise that they are drooling. If you are concerned, speak to a doctor about having your kid evaluated by a speech therapist, dentist, or ear, nose, and throat (ENT) expert who can determine the best course of action.

    How Is Drooling Treated?

    Drooling is a natural aspect of a baby's growth and development.

    When a child reaches the age of two, however, drooling is not typical. Drooling in a child is not normal, so if yours continues past the age of two, you should be concerned.

    There's a medical need, so you should see a doctor about it. For instance, you should see a doctor right away if your child is drool excessively since it could interfere with his ability to interact socially and perform normal daily tasks. Your child's doctor will check for the following symptoms if your child drools excessively to diagnose the cause and provide a therapy.

    • If your kid can learn to keep his lips closed and move his tongue, he's got some serious skills.
    • If your kid normally swallows, that's good news.
    • If his nose is blocked or he gets a cold.
    • If the baby has a healthy reflex to swallow on its own.
    • How the child is sitting and whether or not his jaw is set firmly.

    The subsequent course of therapy is based on the results of these examinations:

    • Training the kid to keep his or her mouth shut.
    • Eliminating or drastically reducing the child's consumption of acidic foods.
    • Improving the kid's swallowing skills.
    • Facial muscles tensing up.
    • Increasing the child's ability to sense whether his lips or face is wet.
    • His jaw, cheeks, and lips will be given the benefit of oral motor treatment. The treatment will aid him in properly swallowing his saliva.

    Oftentimes, drooling is ignored rather than handled. If you are under the age of four or if you drool while sleeping, for instance, your doctor probably won't suggest any medication. When drooling is excessive, medical help may be needed. You may have a severe case of drooling if your saliva leaks from your mouth over your clothes or if it causes you to be socially awkward. When a person drools excessively, they risk getting pneumonia by breathing in their own saliva.

    Each patient is unique, and so is each doctor's approach to treatment, but in general, your healthcare provider will evaluate your condition and symptoms and devise a strategy for managing them that actually works for you.

    Medication and orally motor therapy are two examples of interventions that fall within the noninvasive category. Surgery and radiation therapy are two examples of more invasive procedures that you and your doctors may discuss if your condition worsens.


    Positioning and postural control are two skills that speech and support workers teach to aid in lip closure and swallowing. Your therapist will also help you with exercises to increase muscular tone and manage your saliva production.

    A nutritionist may be recommended by your therapist in order to reduce the amount of acidic meals you consume.

    Appliance or Dental Device

    When swallowing, a special gadget implanted in the mouth can assist with lip closure.

    If you have any command over your swallowing abilities, this may be a viable alternative for you.


    Some medicines can help lessen your need to swallow so much saliva. Among these are:

    • Scopolamine (Transderm Scop) is available as a skin patch that releases the drug gradually over the course of the day. There is a delay of three days between each patch.
    • Glycopyrrolate (Robinul) can be administered either intravenously or orally. It's possible that using this medication to reduce saliva production could leave you with a dry mouth.
    • Drops of atropine sulphate are administered orally. This is typically administered to a patient at the end of life.

    Botox Injections

    Because Botox helps tighten face muscles, it may be useful in treating drooling.

    Surgical Treatment

    Drooling can be treated with several different methods that have been proven effective. The most typical one moves the salivary glands to the roof of the mouth, where they can't cause embarrassing drooling. The operation also removes your salivary glands.

    What Role Does Drooling Have in a Baby's Growth and Development?

    The answer is a resounding "yes," as drooling is a crucial part of a baby's development. A baby that is teething will start drooling. Drooling and bubble-blowing are also indicators of physical growth in toddlers. A child's newfound ability to drool or blow bubbles indicates he has reached a developmental milestone.

    Babies' developing sense of smell can be observed by the drooling that occurs after they smell milk or food. The enzymes in a baby's drool help them digest semi-solid and solid foods when they're between 4 and 6 months old.

    To prevent irritation to the lining of the oesophagus, saliva acts as a buffer between the stomach acid and the food being swallowed. Saliva also aids in the development of the intestinal lining of the newborn.

    The lubricating properties of saliva also aid in holding food together, making it easier to swallow.


    A Drool Rash: What Is It?

    Babies' lower lips, cheeks, throat, and chest may develop rashes from their frequent dripping of saliva through their mouths.Rashy red bumps may appear on your baby's cheeks, neck, and chest if he drools excessively.

    A baby has drool rash if the rash appears around his or her mouth. To treat saliva rash, wash the afflicted area well, pat it dry, and then use a lanolin-based lotion. A bib tied around the baby's neck will prevent drool from getting on his or her chest and neck.

    Petroleum jelly can be applied to the wound to retain moisture and speed its recovery. But before you put any lotions or creams on your baby's skin, you should consult with your doctor.

    When to Consult a Doctor

    If your child continues to drool after he is four, you should see a doctor. For medical causes of uncontrollable drooling in children, a visit to the paediatrician is in need.

    Consult your child's physician; he or she may recommend counselling or medication. But if it doesn't help, you might want to try something stronger. Drooling is a baby's natural way of making it easier to chew and swallow solid foods. Drooling serves several important purposes for the infant, but if it rises & shows no signs of stopping by age four, it's time to worry. Quickly seeking medical assistance can prevent the deterioration of the current situation.


    Drooling occurs when saliva leaks out of the mouth unintentionally. Drooling happens when the six salivary glands in a human body become overworked. It's possible that babies that drool a lot just have weak jaw muscles or produce too much saliva. the salivary glands in the mouth secrete saliva in response to the taste of food. Babies have trouble getting all that saliva down until they are older.

    Drooling is common in those with medical conditions that make it hard to control facial muscles, such as Parkinson's disease. A infant older than the average drooler's age is said to have excessive drooling if they have trouble stopping the constant flow of saliva from their mouth. Between the first and third months of life, it's possible that a newborn won't produce any saliva at all. If a child is drooling excessively beyond the age of two, it's time to take them to the doctor. A baby's drooling is a normal part of their development.

    Extremely rarely, an excess of saliva could be to blame. When a toddler drools past the age of two, it's cause for alarm. Drooling is frequently disregarded rather than addressed. Excessive drooling can be treated without invasive surgery with medication or oral motor therapy. A more invasive technique, like as surgery or radiation therapy, may be discussed with your doctor if your condition worsens.

    The most common one involves repositioning the salivary glands to the top of the mouth. Drooling is a common symptom of teething in infants. Babies naturally drool when they are learning to chew and swallow solid foods. Saliva protects food from being destroyed by stomach acid. Drool rash occurs when a rash arises on or near a baby's mouth.

    FAQs About Baby Drooling

    This becomes especially apparent at 3 to 6 months of age. The increased flow of saliva that often signals the appearance of a new tooth seems to soothe tender gums; however, if your baby appears to be drooling excessively and looks ill, she may be having trouble swallowing, which requires medical attention.

    If drooling occurs in toddlers or new-born babies, then that is perfectly normal. It is usually a sign that the baby is going to start teething. Moreover, there is no need for concern. But, when it occurs in adults or the cause is not clear, then that is cause for alarm.

    In older people, frequent drooling may be a sign that your muscle control in your mouth and neck is weakening. When you drool, it is due to having more saliva in your mouth. This could be a problem with the throat, the lips, or something else.

    The following are the most common signs and symptoms of teething: Drooling more than usual (drooling may start as early as age 3 months or 4 months, but is not always a sign of teething) Constantly putting fingers or fists in the mouth (babies like to chew on things whether or not they are teething)

    Drooling usually begins at about 2-3 months of age. The first drooling phase lasts until the child reaches 12-15 months of age. Your child is entering the teething stage, which means that drooling will most likely increase. Remember, saliva bathes the teeth and gums, helping wash away excess food and bacteria.
