Oats are more tolerant to extreme conditions than some of their grassy relatives, like wheat, and it is probable that they began to be cultivated in Europe for that reason. This grain continues to be farmed all over the world in areas that are not suited to more finicky grains.
Dental chart (tooth numbering) Teeth are numbered in order to identify them with ease. However there are two common systems of numbering teeth that can confuse unless you know which one you are using. America uses the Universal numbering system and numbers teeth like this:
A normal adult mouth has 32 teeth, which (except for wisdom teeth) have erupted by about age 13: â¢ Incisors (8 total): The middlemost four teeth on the upper and lower jaws. â¢ Canines (4 total): The pointed teeth just outside the incisors. â¢ Premolars (8 total): Teeth between the canines and molars. â¢ Molars (8 total): Flat teeth in the rear of the mouth, best at grinding food. â¢ Wisdom teeth or third molars (4 total): These teeth erupt at around age 18, but are often surgically removed to prevent displacement of other teeth.
