Hyperdontia is a medical condition in which the patient has supernumerary teeth—additional teeth that can appear in any area of the dental arch. In mild cases, a patient may simply have an extra tooth or two, and in extreme cases, they may have upwards of one hundred or more additional small teeth found all along the gums and roof of the mouth.
You can tell how writers worked together on a film by looking at the way the writing credits are stylized. An “&” symbol means the writers worked directly together as a writing team and the word “and” means they worked on the script, but not together. The credits for the film The Last Time I Saw Paris, for example, shows both methods and lists the writers as “Julius J. & Philip G. Epstein and Richard Brooks”, which is meant to be read as “Julius and Philip worked together, and then Brooks worked independently on later drafts”.
