Surprisingly, the timing of when your baby's first tooth comes in can vary quite a bit.
Although the average age for getting a first baby tooth is 6 months, some infants don't get their first tooth until they are 14 or 15 months old. Others can begin teething and get an early baby tooth at 3 months.
The lower, middle two teeth (central incisors) usually come in first, followed by the upper, middle two teeth. The lateral incisors, canine teeth, first, and then second molars all follow, until all 20 baby teeth are in by the time your child is about 2 to 3 years old.
Keep in mind that many children don't follow this typical pattern and their teeth may come in randomly.
Parents often think that their babies are teething when they begin drooling and putting their fingers in their mouth, when they are around 3 or 4 months old.
However, this is often simply a normal developmental milestone and has nothing to do with actual teething. Often, even when infants have these classic 'teething symptoms,' they will not get their first tooth for a few more months or sometimes not until they are more than a year old. So until you see swollen gums or that first tooth coming in, any other symptoms may just be a coincidence.
