I lost my get-go tooth on Tuesday. I was fiddling with it while I was watching Television receiver. I had a mouthful of blood! It soon stopped bleeding. When I looked at the lesser of my tooth the edge was very spiky! Tin can y'all tell me why? – Nicholas, age 6, N Sydney.
Thanks for the great question, Nicholas.
At around 6 months of historic period, babies commonly kickoff getting teeth. The get-go to appear are the sparse front end teeth, called incisors. New teeth proceed erupting from the gums until around two or two-and-a-half years of age. The molars - the flat grinding teeth at the back of the oral cavity - come up up last. In total, you end up with xx baby teeth.
At around half-dozen years of historic period, the bottom incisors start to loosen. When adult teeth outset to grow, they cause the roots of the infant teeth (which are hidden under the gum and hold the teeth to the jaw) to be "eaten away" to make space for the adult teeth working their way upward into the rima oris.
Soon the roots of the babe teeth are eaten abroad until they showtime to get wobbly. Soon information technology gets so wobbly it gets knocked out when you lot swallow something or brush your teeth. Or you might twist it out while y'all're watching Tv, merely like yous did.
At that place often is some blood because the wobbly tooth is still attached to the gum, so that gets torn when the tooth is lost and it bleeds a fiddling. There ofttimes seems to be more blood than there really is because it mixes with your spit.
The edges of your molar were sharp because when the root of the baby tooth is beingness eaten away by the growing developed teeth, information technology tends to kickoff from the middle of the root. Something like a rough beat edge is left when most of the root has been captivated and the tooth is finally lost.
When you look at an 10-ray, you can see that the baby teeth withal take well-nigh of their roots, then they expect very unlike to your fallen tooth. You tin can besides meet that the growing adult teeth don't have complete roots - they however abound for a while after the tooth erupts into the mouth.
Some people lose teeth a bit earlier and some a bit later on than the normal time, but this is usually OK. However, if your first set of teeth start to fall out before you plough five, then it is worth seeing a dentist who is expert at treating kids.
Soon, Nicholas, you will first to get new teeth at the dorsum of your mouth. They're chosen the starting time permanent molars and there are 4 of them, one in each corner.
These teeth will erupt without a baby tooth falling out, equally they are actualization in spots that are currently empty. After that happens, you will take 24 teeth, until you start losing more than baby teeth when yous are nine or 10.
Then you lot'll get more molars at the back (these guys are chosen the 2nd permanent molars) when you are effectually 12, and and so third permanent molars when you are around 18 or so. These ones are often called wisdom teeth.
Infant teeth are actually important. They allow you lot to chew nutrient, have a nice smile, and assist go along space for developed teeth. And then it is skilful to avoid lots of saccharide and brush your teeth twice a day with fluoridated toothpaste.
