There’s a wide variation of when your child will get their first tooth, but on average they’ll cut their first tooth between 6 months and 1 year of age.
However, it’s not abnormal or unheard of for babies to remain toothless until 18 months or even cut teeth at the newborn stage. As soon as that first tooth erupts, you can start taking care of their tooth or teeth using toothpaste using a rice size amount until age 3.
As for dental visits, it’s important to establish a dental home by the age of 1. After that point, regular visits every 6 months are crucial to monitor their progression.
