Baby Teeth Eruption Chart: Order and Timing

· Dr. Navreet Sidhu · Medically reviewed by Dr. Navreet Sidhu

Most babies get their first tooth near the middle of the first year, but healthy timing varies widely. The lower front teeth often appear first, followed by the upper front teeth, side incisors, first molars, canines, and second molars. Most children have all 20 baby teeth by about age three.

The usual baby-tooth eruption sequence

A chart is most useful as a sequence, not a deadline. The two lower central incisors commonly arrive first, followed by the upper central incisors. Lateral incisors usually fill in beside them. First molars often erupt before the pointed canine teeth, and second molars tend to complete the primary dentition. Teeth often emerge in pairs, but one side can lead the other by weeks or even months. A child's pattern should be interpreted alongside growth, family history, medical history, and what is visible in the mouth.

How much variation can still be normal?

Some healthy infants erupt teeth earlier than expected, while others remain toothless beyond the first birthday. Siblings may follow very different schedules. A small difference between the right and left sides is common, and the order can vary without signaling a problem. What matters more is the overall pattern: whether teeth continue to appear, whether the gums and jaw look healthy, and whether development is otherwise progressing. A chart cannot diagnose delayed eruption because it does not show where a tooth is positioned under the gum.

What a pediatric dentist checks

During an examination, the dentist looks at which teeth have erupted, whether there is enough space, whether the enamel formed normally, and whether any tooth appears blocked or unusually positioned. Imaging is not automatically needed simply because a child is later than a chart. It may be considered when the examination, age, asymmetry, medical history, or prolonged delay suggests that seeing the developing teeth would change the plan. The goal is to distinguish normal variation from a local or developmental reason for delay.

Caring for teeth as they appear

Begin cleaning a tooth as soon as it is visible. Use a small, soft brush and the amount of fluoride toothpaste recommended for your child's age and risk. Keep bedtime routines consistent, avoid putting a child to bed with sweetened liquids, and establish a dental home early so eruption, enamel, feeding habits, and cavity risk can be followed over time. The eruption chart belongs in that larger prevention plan; it should not create anxiety when a healthy child falls outside an average range.

When to contact the dental team sooner

Arrange an evaluation sooner when a tooth appears at birth, eruption is markedly one-sided for a prolonged period, a firm swelling or blue-purple cyst is present, your child has pain or drainage, or no teeth have appeared well beyond the expected range. A pediatric dentist can decide whether observation, imaging, or medical coordination is appropriate.

Questions parents often ask

What is usually the first baby tooth?

The lower central incisors—the two bottom front teeth—are often first. That is a common pattern rather than a rule, so a different first tooth can still be normal.

Do baby teeth always erupt in pairs?

They often arrive near one another, but one tooth may lead its partner. A short delay between sides is usually not concerning by itself.

How many baby teeth should a three-year-old have?

Most children have 20 primary teeth by roughly age three. A child who has fewer may simply be following an individual schedule, but the dentist can check the pattern during routine care.
