Your baby is teething when his
or her first set of teeth, called primary teeth, break through the gums.
usually begins around 6 months of age. But it is normal for teething to start
at any time between 3 months and 12 months of age. By the time your child is
about 3 years old, he or she will have all 20 primary teeth.
lower front teeth usually come in first. Upper front teeth usually come in 1 to
2 months after the lower front teeth. See a picture that shows
when the primary teeth come in.
Some babies are fussier
than usual when they are teething. This may be because of soreness and swelling
in the gums before a tooth comes through. These symptoms usually begin about 3
to 5 days before the tooth shows, and they disappear as soon as the tooth
breaks the skin. Many babies don't seem to be affected by teething.
Babies may bite on their fingers or toys to help relieve the pressure in
their gums. They may also refuse to eat and drink because their mouths hurt.
Many babies drool during teething, which can cause a rash on the
chin, face, or chest.
Mild symptoms that get better usually are
nothing to worry about. Call your doctor if your baby's symptoms are severe or
don't get better.
Here are some tips to help your baby feel better while
The U.S. Food and Drug Administration (FDA) warns against using teething gel on a baby's gums to reduce pain. The gel can make a baby's throat numb. This may cause difficulty swallowing. The medicine in the gel may also harm a baby.
Learning about teething:
Knowing what to expect:
Primary teeth are usually known
as "baby teeth." Usually, the first primary tooth comes in (erupts) at about 6
months of age, although it can be as early as 3 months or as late as 1 year of
age. In rare cases, a baby gets a first tooth after his or her first birthday.
By age 3, most children have all 20 of their primary teeth.
Primary teeth usually erupt in a
Secondary, or permanent, teeth usually begin replacing
primary teeth around 6 years of age. Permanent teeth erupt in roughly the same
sequence as primary teeth. Usually, a permanent tooth pushes the primary tooth
out as it erupts.
Many times you might not know
that your baby has a new tooth coming in until you see it or hear it click
against an object, such as a spoon. Some babies may show signs of discomfort
from sore and sensitive gums, be cranky, drool, and have other mild symptoms.
These symptoms usually begin about 3 to 5 days before a tooth erupts and go
away as soon as the tooth breaks through the gum.
Teething does not cause diarrhea or diaper rash. It can cause a mild fever up to 101°F (38°C). Mild symptoms
that gradually improve usually are nothing to worry about and may even be
related to a viral infection or other condition. Severe or ongoing symptoms
should be closely watched and discussed with your doctor.
Do not hesitate to call your
doctor any time you have
concerns about your child's teething. It is also a
good idea to talk to your doctor if your child has
unusual tooth development, such as late eruption of
the first tooth. Tooth development issues usually resolve on their own or are

Your doctor may refer
your child to a
dentist who specializes in children's teething
problems, if this seems to be needed.
All children need early and regular
dental care. During
well-child visits the doctor will check
your child's dental health. A visit to a dentist is recommended within 6
months of when your child's first tooth comes in but no
later than your child's first birthday.footnote 1
Some parents dread their child's first visit to the dentist's office.
You can make a trip to the dentist more positive for your child if
you choose his or her dentist carefully. Talk to your
child about what to expect. And if you want, use books that are
meant to help a young child prepare for the first dental
exam. If you have concerns about how your child will behave, talk to your
dentist before scheduling the visit. Your dentist may allow your child to come
in once or twice before being examined. These types of visits help prepare your
child and often make him or her more comfortable with the dentist, other staff,
and the office environment.
Regular dental visits are important to teach your child good dental care
and to help prevent
cavities and other problems. The exam also helps to
identify and treat problems early and prevent them from becoming more serious.
