Baby Teething Timeline

This baby teething timeline documents the average development of a baby’s teeth and may not be accurate to your own experience. Babies are not all alike; your child may be a late bloomer, or may not experience any teething symptoms. These signs are not necessarily a cause for alarm. To be absolutely certain your child’s teeth are developing properly, maintain routine check-ups with your dentist at Assiniboine Dental Group.

3 Months – Teething Begins

The first signs of teething start to reveal themselves pretty early on. Your baby’s gums may look red and swollen. She may drool more often, avoid eating and instead gnaw on furniture or clothing, and she may be a little fussier in reaction to her discomfort.

For a list of recommendations on easing your baby through the teething phase, we get more in-depth about it here.

6-12 Months – First Teeth

Due to their shape, the first teeth to erupt are the two bottom front teeth (lower central incisors) followed by the top four front teeth (upper central and lateral incisors). Sometimes the reverse is true, and the top four teeth erupt first.

Babies can sometimes begin developing teeth as early as three months and as late as one year.

15 months – Molars

Your child’s molars begin to erupt on both the top and bottom. This is a slower process than the first eight teeth and can be a more painful experience for your baby.

Sometimes a cyst can develop between the tooth and the gum, which can cause a lot of discomfort and pain. Eventually, this cyst will burst, which may look messy when it happens, but at that point, the pain is over for your child.

18-26 Months – Canines & Second Molars

The canines are the pointy teeth that emerge on either side of the front four teeth. These teeth help with tearing into tougher foods. The second molars slowly begin erupting when your child is around 2 years old. Typically, the top molars arrive before the bottom.

5 Years – Losing Baby Teeth

Children begin to lose their baby teeth between the ages of 5 and 12, and typically in the same order that they erupt. At this point, your child should be making regular visits to her dentist to determine how her adult teeth are forming and whether or not she’ll require braces.

25 Years

Yes, it’s quite a jump, but we’d be amiss if we didn’t mention the wisdom teeth.

These teeth are the third set of molars in the back of your mouth and they are very slow to erupt. Sometimes they don’t erupt at all, or they come in sideways and crowd the rest of your teeth, causing pain and problems with your bite. In situations like this, the teeth may need to be removed, but not always.

We can determine through X-ray whether these teeth are growing in properly or not. As always, maintain regular visits to your dentist at ADG.
