When do your teeth grow and fall out?

Updated: Dec 18, 2018

There are two types of teeth:  Milk Teeth (baby teeth) and Adult teeth.

Milk teeth:

Babies' teeth actually begin to develop in the womb, and there have been cases known where babies have been born with a tooth/teeth already erupted.  In most cases, however, their very first teeth don't come through until they're between 6 and 12 months old. Most children have a full set of 20 milk or baby teeth by the time they're three years old.

When they reach five or six, these teeth will start to fall out, making way for adult teeth.

Adult teeth

Between the ages of 5-7, children start to grow their first adult molars.  By the age of 12-14, most children have lost all their baby teeth and have their adult teeth. There are 32 adult teeth in total.  The last four of these, called wisdom teeth, usually appear much later than the others, generally between the ages of 17 and 25.  In some cases, people never get their wisdom teeth!

There are four different types of teeth:

Incisors. These are your four front teeth on the top and bottom jaw. They are used for cutting and chopping food.

Canine teeth. These are the sharp, pointy teeth.  Next to your incisors on the top and bottom They help to tear food.

Premolars. Next to your canine teeth are your premolars.  You have eight premolars in total, four on your top jaw and four on the bottom. They are bigger and wider than your incisors and canine teeth, and are used chewing food.

Molars. You have eight molars, four on top and four on the bottom. These are your strongest teeth and work with your tongue to help you swallow food.

As we have developed over the years, our life span has increased.  Today, the average life expectancy for a man in the UK is 79 and for a woman, 83.  Now more than ever, our teeth therefore need to last us longer.  With the right oral care techniques at home, combined with regular routine visits to your Dentist, your teeth can hopefully last your lifetime!
