That first tiny tooth appearing in your child’s smile is more than a cute milestone. It is the beginning of a carefully timed and fascinating process known as the stages of tooth eruption in children. Understanding how and when baby teeth and permanent teeth emerge helps parents identify normal development, plan timely dental checkups and address any early concerns.  

If you want clarity on the full eruption timeline and what each stage means for your child’s oral health, this guide will walk you through every essential detail. Dive into the sections below to explore the complete eruption journey and learn how the Radiant dental care can support your child at every stage.

Understanding Tooth Eruption in Children and Why It Matters

Tooth​‍​‌‍​‍‌​‍​‌‍​‍‌ eruption actually refers to the process whereby teeth make their way out of the gums and into the mouth and become visible. Besides, it helps the child to chew, develop speech, grow the jaw and eventually, it makes the way for the permanent teeth. In general, the order of eruption is quite predictable even though each child has different timing.

It is important to monitor the stages of tooth eruption in children as it helps to recognize early or delayed teething, deal with teething pain, follow the spacing and crowding, schedule dental appointments and start oral hygiene practices at the right time. For this reason, some parents take the best dental hospital in Chennai and the best dentist in Chennai as their guides during these years of growth. 

The dentition of children is divided into two sets. Primary or baby teeth are 20 deciduous teeth appearing between 6 months and 3 years and serving as holders for permanent teeth. The permanent set has 32 teeth that start to come out at around 6 years and go on to the teenage years, thus, supporting the long-term chewing function and jaw ​‍​‌‍​‍‌​‍​‌‍​‍‌alignment.

Care Tips:

Complete Primary Teeth Set: Around Age 3

By age 3, most children have all 20 baby teeth.

  • Regular dental checkups become essential
  • Alignment and spacing should be monitored
  • Eating and speech gradually improve

If you’re looking for reliable pediatric consultations, visiting the best dentist in Chennai can help ensure your child’s oral growth is monitored professionally.

Shedding of Baby Teeth: 6–12 Years

This is the transition from baby teeth to permanent teeth.

What Happens: 

  • Baby teeth loosen and fall out
  • Permanent teeth erupt in a similar sequence to baby teeth

Common Signs:

  • Mild gum discomfort
  • Wiggly or shifting teeth
  • Temporary gaps

Care Tips: 

  • Encourage gentle wiggling
  • Avoid pulling teeth early
  • Maintain brushing and flossing habits

Common Concerns During Tooth Eruption

Parents may notice challenges during different stages. Here are the most frequent ones:

  • Delayed Tooth Eruption: If no teeth appear by 15 months, consult a pediatric dentist.
  • Early Eruption: Usually harmless but should be monitored if feeding becomes difficult.
  • Teething Fever Myth: Teething does not cause high fever. Persistent fever requires medical attention.
  • Crooked or Overlapping Teeth: Common during transitions. Teeth often self-correct as more erupt.
  • Cavities in Baby Teeth: Baby teeth are prone to decay, which may impact permanent teeth.

Regular visits to a trusted pediatric dental clinic such as Radiant Dental Care can help detect and prevent early issues.

Importance of Regular and Immediate Dental Visits

Routine dental checkups play a key role in spotting bite problems, early tooth decay, eruption delays, and spacing or alignment issues. Many parents choose the best dental hospital in Chennai for reliable monitoring and a comfortable, child-friendly experience. However, immediate dental care is necessary if you notice persistent tooth pain, gum swelling, mouth or jaw injury, unusual tooth discoloration, or a baby tooth not falling out while the permanent tooth begins to erupt. Early attention to these concerns helps prevent long-term dental complications.

Frequently Asked Questions: 

1.​‍​‌‍​‍‌​‍​‌‍​‍‌ When does the first tooth usually appear in children?

2. How long do baby teeth come in?

Ans. The primary (baby) dentition of 20 teeth usually will have the complete eruption of the teeth by the age of 2.5 to 3 years. Parents during this time are supposed to monitor the pattern of teething, the condition of the gums and the spaces that ​‍​‌‍​‍‌​‍​‌‍​‍‌occur.

3. What signs indicate that my child is teething?

Ans. The most typical symptoms are drooling, gum swelling, irritability, chewing on something and a little change in eating or sleeping. The signs are quite usual and most of the time they are of a short duration.

4. When do permanent teeth start replacing baby teeth?

Ans. After 6 years of age, the first permanent molars and front incisors are the ones that are followed by the rest of the permanent teeth to replace the baby teeth. This change stays until early teens.
