My premise [about community policing] is you have to start first by asking questions like: How does this impact patrol? Do I have enough people to do this? What do the officers think?
In humans, there are usually 20 primary (baby) teeth and 28 to 32 permanent teeth, the last four being third molars or  wisdom teeth , each of which may or may not grow in. Among primary teeth, 10 usually are found in the maxilla (upper jaw) and the other 10 in the mandible (lower jaw).
The standard number of primary teeth is 20 and the standard number of permanent teeth is 32. Primary teeth are the first set of teeth that erupt in a person's mouth, generally by the age of 36 months, and are shed by the time the person is about 12 years old. Permanent teeth then take the place of the primary teeth and are usually fully erupted by the time the person reaches 21 years of age.
