Why do we have ridges in our teeth when we just get them in?

I remember losing teeth, and the new ones that came in having ridges on them. Over the years, they kind of just disappeared. But why do we have the ridges on them? Does anyone know?





Thanks! I'm just curious...Why do we have ridges in our teeth when we just get them in?
yes

Why do I have ridges on the tip of my teeth?

Im 14 And I Have Ridges On Most Of My Teeth..Why do I have ridges on the tip of my teeth?
Ok yeah they are just ridges that come in with your permanent teeth, and I think they are there to help the teeth cut through the gums while they are erupting. If that's not the reason they are there, I don't know.





I do know: I had them. Mine were really ugly. I hated them. And then I just forgot about them, and the next time I thought of them they were gone!! Yup, they wear away because they arn't as strong as your actual tooth material. So yup, they will go away, just forget about them and they will eventually happen.





good luck!Why do I have ridges on the tip of my teeth?
Same here!!! I have braces and I am going to ask the ortho if he can ';file'; or if there is another method! I hate it! It lookes weird especiallty when all of my friends teeth don't look like that either! If there is no way to fix, guess we'll just have to endure it and look at it in a positive way- like its a special characteristic!! :)
This is normal all permenant teth when they come out (Erupt ) they have these ridges.


Don't worry about them this is perfictly normal
Because those are your permanent teeth. You baby teeth did not have ridges..they were smooth. That just means that your teeth tougher when used for eating.
Everyone does.


Your teeth have been through a lot in 14 years. Give them a break.


Ridges are nothing!
me too

Why do oceanic ridges segmented?

when i look at geologic map, i always see the oceanic ridges segmented, why are they not straight? what is the mechanism behind this segmentation? and why are they segmented to small segments on the both sides?Why do oceanic ridges segmented?
The upwelling and extrusion of magma and magma bodies is not homogeneous across the length of the ridge. In a simple view, the magma rises in bubbles, so the ridge consists of a series of spreading centers with variable rates of opening (and these rates are not constant through time at a given location). The different segments are connected by perpendicular transform faults that accomodate these variations.

PLEASE ANSWER! An area contains numerous winding ridges, coneshaped hills and small lakes. The area was formed

the area was formed by


1. an arid climate


2. folding of rock layers


3. continental glaciation


4. marine flooding.PLEASE ANSWER! An area contains numerous winding ridges, coneshaped hills and small lakes. The area was formed
Ew, ew, me me me. Pick me. It's number 3. I live in Minnesota and that type of terrain is quite evident here.PLEASE ANSWER! An area contains numerous winding ridges, coneshaped hills and small lakes. The area was formed

Why are there so many ridges and cracks along the San Andreas Fault?

Because there is a shortage of Elmer's Glue in the West.Why are there so many ridges and cracks along the San Andreas Fault?

    The rate and direction of continental drift.What do the patterns of rock ages on the mid ocean ridges tell geologist?
    By examining the patters of ridges, it can be found that new ocean bottom is being created as lava comes up out of the cracks.





    Other information can be discovered about the chemical make up of the Earth's mantle.





    ;-D That is also both a very hot and a very cold place.What do the patterns of rock ages on the mid ocean ridges tell geologist?
    it tells them how many years ago there was a water formation suchas a lake or ocean. the different colors is what helps them make their hypothesis.





    hope I helped u!

    Horst and graben exist along mid-ocean ridges, where new crust is being made. Explain why.?

    A horst is a block of rock which has risen between two faults. A graben is a block of rock that has sunk between two faults. So i need to know why they are found in mid-ocean ridges. This question is from Science Focus 3 by Kerry Whalley, Peter Roberson, Greg Rickard and Isabella Brown.Horst and graben exist along mid-ocean ridges, where new crust is being made. Explain why.?
    A horst is not exactly a block that has risen between two faults. Actually, it is just a block that has not sunk, between two other blocks that have sunk (grabens). This kind of formation is typical of a spreading crust, where the tectonic plates are moving away from each other. That's exactly what happens in mid-ocean ridges. The spreading movement generates faults and makes some blocks to sink into mantle.
