Milk Teeth .....!..What are they for ?
« on: 03/03/2007 02:02:06 »
Why on earth do we have milk teeth ?....why have toothys that we have to lose ?

Why not have proper grup (GRown UP) teeth from the start ?
I realise the mouth is smaller.......AH !!.......*penny dropping moment*..is that the reason why ?..........To accommodate our bigger gobs as we grow up ?

If not .........then  could we just not have adult teeth but less of them as kids....... and more grow as we do ?

whajafink ?

Hi friendo curiousissimus Neilepibus,
I found this commercial site, you may
appreciate it even if is not from your
favourite super PubMed database:

Milk teeth


Milk teeth play an important role in the alignment and spacing of permanent teeth.
They support the upper and lower jaws vis--vis each other. Constant chewing with deciduous dentition is an essential prerequisite for the correct development of the jaws. If milk teeth are lost too early on, the position of the other teeth may be affected, which is why it is important that milk teeth should remain intact until they are replaced by permanent teeth. 
  
Milk teeth are like babies - they need special care. And special protection, because the enamel of milk teeth and new permanent teeth is still soft and not yet fully mature.   
     
How do deciduous teeth develop?    
     
- The first tooth begins to mineralise in the 4th month of pregnancy    
- By the time baby is born, all the milk teeth have been "prepared" and the cusps of the sixth-year molars (1st permanent back tooth) are mineralised    
- They start to erupt into the oral cavity from around 4 months.     
- As a general rule, all 20 milk teeth will have arrived by the time the child is 3years old.     
- Each tooth that erupts into the oral cavity is healthy and free of caries.

Dearest Chumous Friendlithian Ikon,


THANK EWE for this ,

I wonder if certain animals have Milk Teeth too !...

Me also wonders that if we continue to evolve, if  the necessity for milk teeth will subside.

Well,
if deciduous teeth prepare the position for the permanent ones, and all this is precisely programmed in all the special tissues involved...I don't see how this is gonna change in the next few thousand years.
Me no see people with no teeth prevail or anything like mutation-selection-evolution!

Numbers of teeth

Many mammals, including dogs, cats, and ferrets are "diphyodont" meaning they have two sets of teeth, one set (called "deciduous") being shed and replaced by a permanent set. Although the exact number can vary, puppies have 28 deciduous (temporary) teeth, and adult dogs have 42 permanent teeth. Feline kittens have 26 deciduous teeth, and adult cats have 30 permanent teeth. Ferret kits have 30 deciduous teeth, with adults having 34.
