The way you hold your head changes the look of your front teeth. Most of the time, the lips are covered with teeth. The upper teeth usually look longer when you look down. If your head is tilted backwards, your upper teeth will become shorter.
Do not ask if your dentist is completely straight upper teeth. They can look shabby and look older in the photos.
If you have a metal padding or crown, remind the photographer. They can photograph their teeth from different angles without revealing them. If this is not possible, the picture can often be trimmed so that the metal does not show up.
