Yes, some 1-year-olds have teeth, but it's not guaranteed.
Teething Timeline: A Variable Process
The appearance of baby teeth varies greatly among infants. While some babies may have several teeth by their first birthday, others might not have any yet. The first tooth typically erupts between 6 and 12 months, and by 1 year, a child will typically have between two and four teeth. This is supported by multiple sources, including Pampers, which states that all primary teeth typically erupt by 2 1/2 to 3 years of age. https://www.pampers.com/en-us/baby/teething/article/baby-teeth-chart Other sources, like What to Expect, corroborate this, indicating that a one-year-old will likely have 2-4 teeth. https://www.whattoexpect.com/first-year/teething/order-of-baby-teeth-tooth-chart/ Indeed, the first tooth can appear around one year. https://www.babytoothcenter.com/how-many-teeth-should-a-1-year-old-have/
Factors Affecting Tooth Eruption
Several factors influence the timing of tooth eruption:
- Genetics: Family history plays a significant role.
- Nutrition: Adequate nutrition is vital for healthy tooth development.
- Overall health: Illness can sometimes delay tooth eruption.
A delay in tooth eruption isn't automatically cause for concern, but if a 1-year-old has no teeth, consulting a pediatrician or dentist is recommended. https://www.colgate.com/en-us/oral-health/kids-oral-care/kids-with-no-teeth-what-causes-delays-in-tooth-eruption
In Summary
While the presence of teeth at one year old is common, it's also normal for some infants to not yet have any. A range of two to four teeth is typical for this age.
