When Do Babies Start Teething?


Has your baby been irritable, fussy, or unable to sleep? Are they drooling excessively and chewing anything they can get their hands on? If so, it’s possible your baby is teething. 
What is teething?
Babies are born with all 20 fully formed baby teeth (also called “first teeth” or “milk teeth”) under their gums. The process of a baby’s first teeth erupting through the gums is called “teething.”


Typically, the top and bottom front teeth are the first to emerge from the gums, followed by lateral incisors, first molars, canines, and second molars. 
When do babies start teething?
Teething in infants usually starts between the ages of two and 12 months. However, it can take up to two years for all 20 baby teeth to emerge.


As a tooth begins to cut through the gums, it can cause oral pain and soreness. Not all babies show signs of discomfort during this process. But temporary symptoms of teething can begin as early as four days prior to the appearance of a new tooth and can last up to three days after the tooth has emerged.
How do you know if your baby is teething?
While not all teething infants exhibit identical signs of tender gums, there are a number of teething symptoms that may include:

  • Increased drooling, biting, sucking or gum rubbing

  • Decreased appetite

  • Difficulty sleeping

  • Irritability

  • Elevated body temperature

Temporary teething symptoms don’t require treatment. However, while some infants may experience a slight increase in body temperature during the teething process, a persistent fever can be a symptom of a serious infection and should be treated by a healthcare provider.
How can you ease teething pain?
There are several ways to help children alleviate teething pain and gum soreness. 


Teething rings — The pressure provided by chewing can help alleviate discomfort. Teething rings provide a clean and safe item on which your infant can chew.

Cool the area — The cold feeling of a chilled washcloth, teething ring, or a spoon can help soothe irritated gums.

Rub the area — Using a clean finger and a moistened gause pad, you can rub your baby’s gums gently. Much like teething rings, the pressure can help ease gum discomfort.

Temporary pain relief — Pain relief at bedtime can help your baby sleep through the night. Children’s acetaminophen (Tylenol) and ibuprophen (Advil, Motrin) are generally safe for children six months and older. Be sure to read the label to ensure the proper dosage for your baby’s weight.

Teething gels — Teething gels with benzocaine are considered unsafe for children under the age of two. Consult a healthcare professional before using teething gels containing benzocaine.
