The Stages of Tooth Eruption: From Milk Teeth to Permanent Teeth


Last Modified: August 7, 2023


As parents, it’s essential to be aware of the various stages of tooth eruption in our children. Understanding this natural process will help us monitor our child’s dental health and ensure they maintain a beautiful, healthy smile throughout their lives.

In this blog post, we’ll explore the tooth eruption cycle, from the appearance of milk teeth to the emergence of permanent teeth, and provide some essential tips for dental care during this critical period.

Stage 1: The Arrival of Milk Teeth (Primary Teeth)

The tooth eruption journey begins during infancy when your baby starts to develop their first set of teeth, commonly known as milk teeth or primary teeth. This process usually starts around six months of age, but it can vary from child to child.

The first teeth to emerge are usually the lower front teeth, followed by the upper front teeth, and then the lateral incisors, canines, and molars. By the age of three, most children have all 20 primary teeth.

Stage 2: Mixed Dentition Phase

Around the age of six, your child enters the mixed dentition phase. During this time, they will begin to lose their milk teeth as the permanent teeth start to emerge. The first molars and lower central incisors are typically the first permanent teeth to come in.

This stage can be somewhat challenging for children as they may experience some discomfort and anxiety due to loose teeth.

Stage 3: The Transition to Permanent Teeth

Between the ages of six to twelve, your child will continue to lose their remaining milk teeth and replace them with permanent ones. The order of tooth eruption can vary, but generally, the incisors and canines come in first, followed by the premolars, and finally, the second molars. By the end of this stage, most children will have a full set of 28 permanent teeth.

Stage 4: Wisdom Teeth (Third Molars)

During the late teen years or early adulthood, typically between the ages of 17 to 25, the third molars, commonly known as wisdom teeth, may start to emerge.

However, not everyone develops wisdom teeth, and in some cases, they may need to be extracted if they cause crowding or other dental issues.

Tips for Dental Care

  • Start Early: Even before your baby’s first tooth appears, gently clean their gums with a soft, damp cloth after feedings to keep their mouth clean.
  • Begin Brushing: Once the first tooth emerges, start using an infant toothbrush and a tiny amount of fluoride toothpaste to brush your child’s teeth twice a day.
  • Monitor Development: Regularly check your child’s teeth for any signs of decay or abnormalities. If you notice anything unusual, consult a dentist promptly.
  • Teach Proper Oral Hygiene: As your child grows, teach them the importance of brushing and flossing regularly to maintain good oral hygiene habits.
  • Schedule Dental Check-ups: Regular visits to the dentist are crucial to monitor tooth development and address any dental issues promptly.

Understanding the stages of tooth eruption from milk teeth to permanent teeth is vital for every parent. By staying informed and following proper dental care practices, we can ensure our children’s teeth grow healthily and lay the foundation for a lifetime of beautiful smiles.

Remember, regular dental check-ups and a positive approach to oral hygiene will contribute to excellent dental health throughout their lives. By: Dr. Nayanika Batra
