When Will My Baby’s Teeth Come In?

Teething: What To Know And How To Take Action

So first thing is first, what is teething? Teething is when your first set of teeth break through the gums. Pressure from the teeth poking through under the gums causes discomfort. This is the culprit for all that constant urge for babies to chew, chew chew! So when does all this chewing start to happen? Teething usually occurs between 6 to 24 months of age. Since each child is different and there is no exact set time on when teething will stop, we have a few suggestions to ease any aches and pains for the time being.

Pressure

Don’t think that your little one can get enough chewing. Let them have at it! This helps them relieve any discomfort and distracts them from the sensation of pain that the teeth are causing. Be sure to provide safe objects for chewing, such as teething rings.

Painkillers

Check with a doctor to see what particular medication is right for your little one. A common pain reliever, such as ibuprofen (Advil, Children’s Motrin), can reduce inflammation in the gums and reduce any pain for babies who are at least six months old. Keep in mind that aspirin is off-limits to anyone under the age of 19.

Hard Foods

Gnawing on hard food can soothe any pain temporarily. Be sure to keep an eye out for any choking hazards from consuming larger pieces of food!

Cold Objects or Foods

Cold water in a bottle or cold purees can do the trick for relieving any soreness; just make sure nothing is too cold or coming from the freezer which can cause more aggravation for the gums.

Gum Massages

Gently rubbing a clean finger over the sore gums can provide the same relief and distraction as chewing on objects for teething by counteracting the pressure from the gums.

When Will My Baby’s Teeth Come In?

As with most things with children (as you’ll soon learn), their teeth will start come in when they’re ready.  The age your child is when their teeth first start to come in is not indicative of whether they’re developmentally behind or ahead.  And when you’re up at 3AM with a fussy child who’s cutting his first tooth, you’ll wonder why you ever looked forward to this wonderful event.

 

The average time for the appearance of the first teeth is between 5 and 7 months old.  However, teeth could come in as early as one month or they might not reveal their toothy grin until 1.5 years olds.  In some extreme cases, a child can even be born with teeth!  This typically only happens in about 1 out of every 2,000 newborns, and these are often extra teeth that should be removed.

If teeth are very early or very late to appear, you should take your child to a doctor to make sure that it is not indicative of a more serious complication.  Delayed eruption could be caused by a nutritional problem, such as rickets, or a systemic condition, such a hypopituitarism or hypothyroidism.  If baby teeth appear very early, it could indicate a hormonal problem such as hyperthyroidism.

The following tables outline the normal ranges for teeth to erupt and to shed:

***A few facts about baby teeth:

  • A general rule of thumb is that for every 6 months of life, approximately 4 teeth will erupt.
  • Girls generally get their baby teeth before boys.
  • Lower teeth usually come in before upper teeth.
  • Teeth in both jaws usually erupt in pairs — one on the right and one on the left.
  • Primary teeth are smaller in size and whiter in color than the permanent teeth that follow.
  • By the time a child is 2 to 3 years old, all primary teeth should have come in.
