Now that teething pains have been overcome the economy is on the mend.

Most cats have serrations on their penises and apparently it's a painful ordeal for the female.

Once the first permanent tooth erupts into the mouth, the teeth are in the mixed (or transitional) dentition.

During primary dentition, the tooth buds of permanent teeth develop below the primary teeth, close to the palate or tongue.

Mixed dentition starts when the first permanent molar appears in the mouth, usually at six years, and lasts until the last primary tooth is lost, usually at eleven or twelve years.
