Why do all the woman in the Tiscali ad's have such large mouths?

Question

Whenever I go to read my Email etc on a Tiscali site every image of any woman shown on there, or on any mail I receive, always shows a woman with a huge mouth always open. Why?
I could understand it if they advertised tooth paste or other dental products.

Answer 1

Lol...well spotted!

Answer 2

Personally, I haven't seen these women with 'large mouths' but it could be that they have the correct number of teeth!
To explain: the usual method of 'straightening' teeth in the UK is removal to alleviate overcrowding. Often, 2 teeth are extracted at the top and 2 on the lower arch (1 each side)
In the USA, for instance, and in some instances in the UK, teeth are not removed but 'functional appliances' are used. The theory is that this is a skeletal problem (small, narrow dental arch) and not a dental problem.
An appliance similar to a denture with a split down the midde, is used. In the centre of the appliance there is a gear which is periodically turned which widens the appliance.
Wearing this gradually widens the upper arch by a few millimetres at a time so that there is room for the teeth to come down into their natural position. Then a fixed appliance may be worn to align the teeth.
The effect of this makes the mouth/jaw wider with more teeth!
In boys particularly, the finished aesthetics/profile is much more pleasing that a small, narrow arch often with a receding chin.
