Drooling usually begins at the age of two to three months when the baby’s salivary glands become functionally active (1). Babies lack precision control of their neck muscles and thus may not swallow the saliva produced continuously in their mouths. Young infants also do not have teeth to hold back the saliva. Due to these reasons, the saliva has only one way, which is out of the mouth.

But at times, this common phenomenon gets escalated, leading to excess production of saliva in the mouth, causing hypersalivation, also known as sialorrhea (2). This MomJunction post tells you about the drooling in babies, causes of excessive drooling, and what you can do to manage it.

How Does Drooling Help Babies?

According to the American Academy of Pediatrics, drooling helps in the following ways (3):

  • Keeps the baby’s mouth moist.
  • Washes away food residue.
  • Softens foods when the baby starts eating solids, thus making it easier to swallow.
  • Protects the baby’s gums. Once the baby has teeth, the compounds in saliva prevent tooth decay.
  • Saliva works as a natural antacid that helps prevent hyperacidity in the stomach.
  • Saliva naturally contains compounds that convert starch into sugar.

There is no reason to worry if your baby or toddler is drooling excessively but is otherwise healthy. However, you can curb it if you know what’s causing it.

What Causes Excessive Drooling In Babies?

The following conditions might lead to excessive drooling in infants and toddlers:

  1. Teething: Excessive drooling is usually the first sign of teething (4). Your baby can get their first teeth somewhere between five and seven months, when they may salivate more than usual (5).
  1. Orofacial abnormalities: Anomalies of the facial bones, mouth, or lips all contribute to orofacial abnormalities. In most cases, these problems are congenital. Numerous orofacial conditions, such as cleft lip and dysphagia, could cause excessive drooling in babies (6) (7).
  1. Upper respiratory illness: Infection of the upper respiratory system may cause a baby to drool more than usual. An example is an epiglottitis, an infection, and inflammation of the epiglottis, which is a flap of tissue right above the vocal cords. Doctors check for drooling to diagnose it, one of the significant symptoms of the condition (8).
  1. Neurological disorders: Drooling is often linked to disorders like autism and cerebral palsy, and could be one of the earliest symptoms of the condition (9) (10). Autistic spectrum disorders are often linked with low muscle tone and developmental delay, both of which are said to contribute to excessive drooling.

Whatever is the cause, if the baby is drooling unusually more, you may want to visit a doctor.

Should You See A Doctor If Your Baby Drools A Lot?

Not necessarily. If your baby is well in general, then there is no reason to worry about the excess drooling. The condition will go away on its own. But if the following conditions accompany drooling, then it is good to let the doctor look:

  • Sudden excessive drooling could cause the baby to choke. Drooling can also be a sign of a foreign object stuck in the baby’s throat, causing the child to choke (3). If you suspect this, seek medical attention immediately.
  • Fever of 100.4°F (38°C) or above.
  • Excessive fussiness and colic.
  • Inability to eat and sleep properly.
  • You notice redness inside the baby’s mouth and the throat.
  • An older infant with teeth has trouble chewing or swallowing.

Does Excessive Drooling In Babies Require Treatment?

Usually, drooling will not require treatment. If the baby displays other signs of a problem, then the doctor will diagnose the underlying condition causing the drooling and then proceed to treat it. Treatment could range from oral medication to reduce saliva production, to botox injections in the salivary gland (11). In cases of orofacial abnormalities, corrective surgery could also be recommended (6). Whatever the treatment, it will be recommended by a pediatrician post specific diagnosis.

Sometimes, a little home care is all that is needed to deal with drooling in babies.

How To Manage Excessive Drooling At Home?

Managing all that excess saliva is easy with a few simple steps like the ones below:

  • Put on the drool bib: You can buy a drool bib and let the baby wear it all the time. Bibs made from cotton work the best due to the material’s excellent absorbent capabilities. Keep changing the bibs and wash them every day with a baby-safe disinfectant detergent.
  • Keep tissues handy: If you are outdoors, carry a pack of tissues in your baby’s diaper bag. Wipe the excess drool and throw the tissue in a dustbin right away.
  • Give a teething toy: If your baby drools predominantly when he/she is teething, then give them a teething toy. It can help relieve the sore gums and bring down the excess salivation stimulated by irritated gums. Avoid teething necklaces since they increase the risk of strangulation and are not recommended by pediatric experts (12).

Treatment of the underlying condition will also work against excessive drooling. Eventually, the drooling should stop.

Frequently Asked Questions

1. How long does the drooling last in babies?

Drooling will stop between the ages of two and three years. By the end of toddlerhood, most children stop drooling even if they are yet to get permanent teeth. If your child continues to drool excessively beyond the age of three, then it is advisable to take them to a doctor. Drooling could suddenly start in older toddlers if they contract a respiratory illness.

2. Is excessive drooling associated with autism?

Excessive drooling is considered as one of the early symptoms of neurological disorders, especially autism. However, in babies, drooling is a normal phenomenon and does not necessarily mean that the baby is autistic. If you feel that your baby is drooling excessively, consult a pediatrician.

Your child might drool during infancy and toddlerhood. But as your little one grows older, the instances get fewer. Be observant and aware of the child’s overall condition to figure out why they may be drooling. For all you know, the toddler or child simply saw something very delicious and started to drool!
