Babies usually start to get their first teeth around 6 months of age. However, the timing can vary widely—some babies begin teething as early as 3 or 4 months, while others may not have their first tooth until after their first birthday. The earliest teeth to appear are typically the two bottom front teeth (lower central incisors), followed by the upper front teeth (upper central incisors). Most children will have all 20 of their primary (baby) teeth by the time they are between 2 and 3 years old. The sequence usually begins with the lower central incisors, then upper central incisors, lateral incisors, first molars, canines, and finally second molars. The entire process of baby teeth emergence is called teething. In summary:

• First teeth usually appear around 6 months (range 3 to 12 months)
• First teeth to appear: lower central incisors (bottom front teeth)
• Full set of 20 baby teeth usually by age 2 to 3 years

If there is unusual delay or concern, consulting a healthcare provider or pediatric dentist is recommended.
