At Mums NI, we believe that education starts at home. We, as parents, are our children's Primary Educators. Together, we can inspire young minds and make learning fun!
In this Fun Facts Friday, we are checking out teeth! Everyone has them, so get your little ones and snuggle down for this fun fact mission to find out more about them.
What are they made of? When do they grow? How many do we have?
Lets find out . . .
The tooth is made up of 3 main components:
Enamel is the outer part of the tooth that we can see. It's extremely hard and tougher than bone. Enamel can vary in colour from light yellow to bluish white.
Dentine is a hard protective layer underneath the enamel. It is yellow in colour. Over years, enamel wears away and the dentine shows through - which is why older people seem to have yellowish teeth.
Pulp lies at the centre of the tooth and is made up of nerves and blood vessels that supply the tooth with more dentine. Pulp is what gives your teeth their sensitivity to hot/cold liquids and foods.
What are teeth actually for? Well, our teeth are there to break down food by cutting, chewing and crushing before we swallow it. We produce salivia when chewing food which makes it wet and easier to grind down.
Humans grow two sets of teeth during their life time.
The first set, often called baby teeth or milk teeth, start to grow when a baby is around 6 months old. By the time a child is 3 years old, they will have a complete set of baby teeth - 20 in total.
Usually when children reach 6 years old, their baby teeth start to fall out. It's not sore but there can sometimes be a little bit of blood. This is making room for the second set of teeth.
The second set of teeth, often called adult teeth or big teeth, start to push out the first set of teeth. By the time a child is 12/13 years old, they will have a full set of adult teeth - 32 in total.
Sometimes teeth need a little bit of help to sit straight in the gum, so an orthodentist will apply braces to the teeth. These can be worn for 1.5 years up to 3 years depending on what help the teeth need. Braces are quite common and come in a variety of colours.
Teeth come in groups that have their own set of jobs to perform.
Incisors are the teeth at the front that help to bite pieces from food.
Canines are the sharp teeth beside the incisors that hold and tear food apart.
Molars are the bigger chunkier teeth at the back and they grind the food down, making it easier to swallow.
In order to keep your teeth heathly, you will need to brush your teeth twice a day. Once in the morning and again just before you go to bed. This will remove the build up of bateria called plaque. You will need to brush all the surfaces of the teeth to make sure they are sparkling.
Have your child draw their very own toothy picture/self portrait and share it with us. They might just win a little prize.
