Primary teeth are smaller and look whiter than permanent teeth because they have thinner enamel. Their roots are also shorter and thinner. Primary teeth are usually just 20, while there are 32 permanent adult teeth. Permanent teeth will start to appear when a child is around six years old, and the jaw is large enough.
The difference between primary or deciduous and permanent teeth is 1. Size:: primary teeth are small compare to permanet teeth 2. Number:: primary number of teeth :20 permanent number of teeth:32 3. Colour:: primary teeth are white colour because of less mineralized enamel permanent teeth are yellowish because of more mineralizes enamel 4. Mamelons:: mamelons means three bulges on the incisal edges of the newly erupted central incisors. no mamelons for primary teeth and have mamelons for permanent teeth. 5. Enamel:: thinner for primary teeth thicker for permanent teeth 6. Cervical ridge:: cervical ridge means ridge at cervix reagion. cervix means where crown meet root. cervical edge is more prominent for primary teeth compare to permanent teeth. 7. Size of the molar:: second molar larger than first molar in primary teeth second molar smaller than first molar

The deciduous (also called primary or milk) teeth are the first ones to appear and they are fully formed by age of 3. The complete deciduous teeth is 20. At age of 6 the first permanent teeth appear by displacing their predecessors. The complete number of permanent teeth is 32. Permanent teeth are stronger than the milk teeth. The word deciduous means to fall off or out. A tree that loses its' leaves in the Fall is called a deciduous tree. Ones that do not are called evergreens.
baby teeth (deciduous teeth) are generally whiter than permanent teeth. i.e. milk teeth are white, permanent ones are creamy yellow. of course this is different for everyone
Yes.
Infant teeth, also known as primary teeth or baby teeth, start developing in the womb and usually begin to erupt around 6 months of age. These teeth are smaller and whiter than adult teeth and are eventually replaced by permanent teeth. Adult teeth, on the other hand, start developing around age 6 and continue to erupt until early adulthood. They are larger and stronger than baby teeth and are meant to last a lifetime.
humans have a little bit more than 30 teeth.
Adults have 32 teeth differentiated in 16-16 between the two jaws and are categorized in to 4 types i.e, incisors,canines,molar,premolar..This includes the wisdom teeth which are simply a third set of molars. It is possible to be born with less than 32 teeth or more than 32 teeth. If a person has had all four of their wisdom teeth removed, they will have 28 teeth. If they have also had braces, which oftentimes requires the removal of the four first bicuspid teeth, they will function in life with 24 teeth. Children have 20 teeth, once they all come in of course. By the age of 2 years most children have all of their primary (baby) teeth.20http://en.wikipedia.org/wiki/Teeth#Anatomy Humans usually have 32 permanent teeth (and 20 primary teeth (also called deciduous, baby, or milk teeth))
1-The primary dentition is smaller in size than secondary dentition,except mesiodistal length of molar about 1/3 bigger than premolars. 2-Primary dentition is bluish,white and more opaque than secondary. 3-Primary dentition have more pronounced cervical margin. 4-Crowns of the anterior primary dentition are more bulbous,pronounced labial cingulum. Dr. Abdulwahab Al-kandari
There is no difference.They are smaller than permenant teeth.There are only 20.Pre molars are absent.
