When Do Babies’ Teeth Develop?

The first tooth generally appears by the age of six months.

Most babies develop primary teeth, also known as milk teeth or baby teeth, during infancy, which is between four and twelve months. However, teeth development begins during the gestation period itself. Thus, mothers are advised to eat healthily and avoid certain medicines, such as tetracyclineiAntibiotic medicine used to treat infection caused by bacteria. , to ensure the fetus’s healthy teeth development (1).

At six weeks of gestation, the tooth’s basic substance is formed, and by three to four months of gestation, the hard tissue surrounding the teeth gets formed. The next stage, known as eruption, occurs when the primary or baby teeth protrude through the gum after the child is born (1).

The first tooth generally appears or erupts by the age of six months, and by the age of three years, toddlers have a set of 20 primary teeth. However, as every child is different, the first tooth may erupt as early as four months in some children. These primary teeth are shed throughout childhood (1) (2).

When Do Children Start Losing Teeth?

John Funk, a preschool teacher and former president of the Utah AEYC, recounts the moment when his granddaughter lost her first baby tooth. He shares, “My granddaughter lost her first baby tooth this past week. Such a growing-up milestone! When your my age, losing a tooth would be a growing-OLD milestone. Not one that I want to experience anytime soon. The new lost tooth, however, does represent a growth process in the physical development of a young child (i).”

 By 10 to 13 years, children have permanent teeth.

The first set of teeth, also known as deciduous teeth, are replaced by permanent teeth. When a permanent tooth erupts, it causes resorptioniInflammation and loss of tooth tissue. of the root of the primary teeth. This leads to loosening, and the baby’s tooth is held only by a small amount of tissue (3).

Usually, children start losing their primary teeth at around six years of age. The central incisors (the middle teeth in the front) are the first ones to be replaced by permanent incisors. By the age of 10 to 13 years, all baby teeth are shed and replaced by permanent teeth and by the age of 21, all 32 permanent or adult teeth erupt (1) (2) (3).

How Many Baby Teeth Do Children Lose?

Between six and 13 years of age, children lose all 20 primary teeth to be replaced by permanent teeth. Specific developmental differences can also determine how many teeth will develop. When babies lose their teeth due to accident or decay, permanent may teeth erupt prematurely. This may lead to crooked teeth due to limited space (1). Hence, it is essential to maintain good dental hygiene. Make them the habit of using toothbrush and toothpaste right from a young age. Also ensure your child does not forget to brush and floss their teeth regularly. Also, ensure to take your child for dental check-ups at the orthodontist at regular intervals.

You may get your child’s teeth checked every six months. However, some doctors may ask you to visit every three months (8).

Timeline For Tooth Eruption And Shedding

The average timeline for eruption and shedding of baby teeth is as follows (2).

How To Get Loose Teeth Out?

In anticipation of the tooth fairy, children may try to poke and pull out the loose tooth with a finger or tongue. They may also wish to pull it out as it can cause discomfort. If your child insists on pulling out the loose tooth, you can try these options (3).

  • Hold the loose tooth with the help of a gauze or a tissue and twist it quickly to pull it out. Do not pull it out just because it makes the child uncomfortable. Sometimes, from becoming loose to dropping out, tooth shedding can take a few weeks to months.
  • If a primary tooth does not loosen on its own even after your child has crossed the age of 13, take your child to a dentist for tooth extraction.

Dentists can apply sealants on your child’s molar teethiFlat, grinding teeth at the back of the mouth. since their grooved structure makes them more prone to cavities. The sealant prevents plaqueiA coating that develops on teeth’s surface over time that contains bacteria. from accumulating in the teeth (9).

What To Do After A Child Loses A Tooth?

Here are a few things you could do after your child loses a baby tooth.

  • It is always a good idea to have a chat with your child about teeth and oral hygiene. It soothes the nerves and helps keep them calm in case of slight bleeding, tingling sensation, or pain.
  • Inform them beforehand that the sensation and bleeding would be minor and end after some time.
  • After the tooth falls, make the child rinse the mouth and hold a damp towel over it for a few minutes to stop the bleeding.
  • In case of pain, use a doctor-recommended oral analgesiciA medicine used to relieve pain. and watch for an hour. If the pain and bleeding persist, take the child to the dentist.

Remember that a dental appointment is not an indication of a problem.

The American Academy of Pediatrics (AAP) and the American Academy of Pediatric Dentistry (AAPD) recommend that all children by the age of one see a pediatric dentist and have a “dental home” (4). After the eruption of the first primary tooth, and by their first birthday, take the child to a pediatric dentist. The dentist will check for any dental issues and offer you oral hygiene tips.

Why Do We Have Two Sets Of Teeth?

We have two sets of teeth in our lifetime — 20 baby teeth and 32 permanent teeth. Baby teeth not only help children eat but also act as placeholders and create appropriate space for the eruption of permanent teeth.

When a permanent tooth erupts, the root of the baby tooth is dissolved. This causes the tooth to become wiggly, and it is only held by the surrounding gum tissue. When the baby tooth is shed, the adult tooth takes its place.

All baby teeth are not shed at once but gradually. This process is essential to maintain the jaw shape and facilitate chewing, biting, and speaking.

Frequently Asked Questions

1. Is it normal for a four-year-old to lose teeth?

Children may start to lose their teeth around the age of six years. As per a case study published in the National Library of Medicine, early teeth loss in children could indicate hypophosphatasia, an inherited disorder that disrupts the mineralization of bones and teeth (5). The signs of hypophosphatasia may differ in each child. Bowed legs, short stature, frequent mild diseases, and rickets are some other symptoms of hypophosphatasia. If you notice any signs of hypophosphatasia, consult a doctor for diagnosis (6).

2. What happens if the baby’s teeth don’t fall out?

Late falling of early teeth may hinder the growth space of the adjacent permanent teeth. These baby teeth may also hinder the growth of the permanent teeth beneath them, thus causing the permanent ones to grow crooked.

3. What can children eat after losing a tooth?

Give your child plenty of fruits and vegetables after a tooth loss. The fiber in fruits and vegetables helps clean the gums and teeth. Also, include milk and milk products in their diet as calcium and phosphorus promote healthy teeth growth (6). Make sure they don’t chew from the side where the tooth was extracted.

Children losing their milk teeth is an important milestone for every child and parent. You may wonder when do kids start losing teeth if their bunny-like tiny teeth start appearing. Baby teeth, also known as milk teeth, begin to fall out around the age of six and continue until they are replaced by a permanent set of teeth by 12. Because the baby teeth help to create space and adequate conditions for the permanent teeth, it is essential that you take proper care of your child’s oral health from the beginning. Therefore consult your child’s dentist and take the necessary measures to maintain proper oral hygiene and prevent early teeth loss or eruption and tooth decay.
