Primary (baby) teeth:
A. the 2 lower central incisors +4 upper incisors
B. upper and lower first molars (bicuspids)
C. upper and lower cuspids (canine)
D. upper and lower second molars
Secondary (adult) teeth:
A. upper and lower central incisors and first molars
B. upper and lower lateral incisors
C. upper and lower molars (bicuspids)
D. upper and lower second molars
E. upper and lower third molars (about 18 years old)
Why?
The theory is that the periodontal ligament provides the main way with the shrinking and cross-linking of collagen fibers.
teeth erupt in wrong place
Yes, deciduous teeth are very important. They "provide the eruption path" for the permanant teeth to follow. They also act as space maintainers as teeth naturally move forward in the absence of an adjacent tooth. Also the eruption of permanent may be delayed if deciduous teeth are extracted much early than their shedding time.

Delayed Dentition refers to a delay in the eruption in the first or second sets of teeth
yep! it does hurt....so let your dentist check it and give you antibiotics to lessen the pain, they will also recommend that you get your teeth a panaromic xray.
Teeth can determine a person's age by the sequence that the teeth appear at particular ages. Lines that grow on the enamel of teeth, helps to show the age.

The process of a horses teeth constantly 'growing' is commonly called eruption. A horses teeth don't really 'grow' once they become adults, it just seems like they do. As a horse wears down its teeth more of the tooth erupts over the gum line to replace what has been worn down. Typically once a horse reaches it's twenties or thirties it will have worn down all of it's teeth and the eruption process stops.
Yes, some dentist might suggest that extracting primary teeth when they are almost out can help the eruption of adult teeth, but there is no proof that this prossess really helps. Put in mind that extracting primary teeth too early can move teeth, making less space for adult teeth.
impacted teeth is prevented from eruption in the oral cavity because of some physical barrier whereas submerged tooth is not prevented by any physical barrier
