a) True

Crowns are typically made from gold, silver or other metal alloys, PFM, and ceramic compounds such as zirconia and porcelain for restoring teeth.

Permanent crowns can be made from all metal....

b) False

Tooth enamel is the hardest substance in the body. The shiny, white enamel that covers your teeth is even stronger than bone....

c) False

Generally, the average adult will have a total of 32 permanent teeth. The "wisdom teeth", or third molars, are the last of the permanent teeth to erupt into the mouth. This tends to occur at the age of 18-25 years.Age may vary....

we should have approximately 20 primary teeth. As we get older, these teeth shed and an adult human should have 32 teeth.
