When Will my Baby’s Teeth Come In?

The development of milk teeth starts from the fetal period.

Evidence of teeth development is visible in the sixth week of embryonic life.

At the time of birth, the baby has 20 milk teeth (10 in the upper jaw and 10 in the lower jaw) hidden in the jaw bone and under the gums.
Parents usually have different questions about teething time, symptoms, and ways to relieve pain related to teething.

The following content answers these questions to some extent and reduces some of their concern in this field.

Baby Teeth

Time and sequence of baby teeth eruption

The normal time for the growth of milk teeth in most children is between 4 and 7 months. Of course, the growth time is not the same for all children.

It may happen in some children earlier than this time (3 months old) or later than this time (after one year), which is completely normal.
Usually, the first erupted milk tooth is the front middle tooth of the lower jaw. The growth of baby teeth is usually completed by the end of three years; at this age, the child has 20 baby teeth.

Although the growth time is different, the order of milk teeth growth is usually as follows:

  1. The two middle anterior teeth of the lower jaw are usually the first erupted teeth and generally occur between 6 and 10 months of age.
  2. Eruption of the upper jaw’s two front teeth usually happens between 8 and 13 months.
  3. The front teeth on the side of the upper and lower jaw usually grow between 8 and 16 months; in most cases, the teeth of the lower jaw tend to grow earlier.
  4. First molars of the lower and upper jaw usually erupt between 13 and 19 months.
  5. Upper and lower canine teeth usually erupt between 16 and 23 months.
  6. And finally, the milky second molars grow between the ages of 25 and 33 months

Baby teething symptoms

Babies and children show different symptoms during teething.

In some babies, teeth grow without pain and discomfort, but in others, it is accompanied by pain and discomfort. The following symptoms are usually seen during teething in babies and toddlers:

  • Restlessness during the day
  • Increase in finger sucking
  • Rubbing the gums
  • Increasing the flow of saliva and its exit from the mouth
  • Some loss of appetite

Since tooth eruption is a natural physiological process, it is not justified to associate it with fever and systemic disorders.

If the child has a fever, diarrhea, and runny nose, especially if these symptoms continue for more than a day, do not consider it a sign of teething, and be sure to consult a pediatrician.

Tips for helping your Baby Teeth

A cold compress can be used to reduce the pain and discomfort of the baby.

To do this, leave a piece of clean and wet cloth in the refrigerator for a while, then ask the child to chew it (if the child can chew due to his young age).

This procedure reduces the child’s pain and discomfort. Massaging the growing area with a clean finger can relieve the baby’s pain.

There are also unique rubber rings that you can first put in the refrigerator and then ask the child to bite.
If pain and discomfort continue, visit the child’s dentist to prescribe painkillers.

Never use local anesthetic gels for pain relief without consulting a pediatric dentist because these gels, especially those containing benzocaine, have side effects.

When Baby Teeth Fall Out

From age 6, the front milk teeth start to loosen and fall out and gradually replace the permanent teeth. It is normal for front milk teeth to loosen up to one year before this age.
The first loose tooth is usually the middle front teeth of the lower jaw. At this time, it is recommended to explain to the child that tooth loss is a natural process to reduce some of his worries.
Over time and with increasing age, other milk teeth are also replaced by permanent teeth, and at the age of 11 to 13 years, all milk teeth are usually replaced by replacement permanent teeth.
At 6 to 7 years old, the first big permanent molar (tooth 6) grows behind the baby’s teeth. Most parents assume this tooth is a baby tooth because it has not been replaced with a baby tooth.

While this thinking is not correct and this tooth is permanent. Because at this age the child does not pay much attention to oral hygiene, the highest rate of decay among permanent teeth is related to this tooth.

Therefore, note that the tooth that grows behind the last milk tooth at 6-7 is permanent, and you should be more obsessed with keeping it healthy.

Premature loss of milk teeth

Some parents may think that because baby teeth are temporary and eventually loosen and fall out, they are not as important as permanent teeth and do not need care and treatment. Do not forget that your children’s milk teeth are very valuable because they need the strength and health of their milk teeth to chew, speak, and have a beautiful appearance. In addition, milk teeth maintain the necessary space for the growth of permanent teeth and play an essential role in guiding the growth of permanent teeth. As a result, efforts should be made to care for and maintain them.
If your child loses his milk tooth before the due date, take him to a pediatric dentist so that, if necessary, he can place a device called a space retainer in the space of his milk tooth. This device does not allow the adjacent teeth to move into this space and the space is preserved for the replacement permanent tooth to grow. If this device is not used, the adjacent baby teeth will move towards the toothless area and reduce the space necessary for permanent teeth to grow in this area. As a result, this can become an obstacle to the growth of permanent teeth.

A complete set of teeth: 13 years old

Your child will probably have all 28 permanent adult teeth by age 13. His four wisdom teeth fall out between the ages of 17 and 21. Talk to a pediatric dentist if you have any concerns about your child’s teeth.
