Quadrant is how a dental team names the four sections of your mouth.

In kid words

"Your mouth is split into four sections called quadrants, kind of like four neighborhoods, so the dentist can say exactly which part they're looking at." Your child does not need to memorize this. It is simply a word they might hear us use while we work, nothing to think about twice.

The parent version

Quadrant describes one of four sections a dental team uses to divide the mouth for reference: upper right, upper left, lower right and lower left. It is a way of organizing an exam or a chart note, not a diagnosis, and hearing it does not signal that anything is wrong in that particular section.

The word shows up constantly in professional conversation and rarely at home, since most families simply point to a tooth or describe it by name instead. If you would like to know exactly where in your child's mouth something was noted, ask your pediatric dentist to show you.

Where you might hear it at our office

During a comprehensive exam at a cleaning and exam visit, our team works through your child's whole mouth section by section, and quadrant is simply the word for each of those sections. You might hear it called out loud while a cleaning or exam is underway, purely as a way of narrating where attention is at that moment.

Any other word from a visit that did not quite stick is worth a look through the rest of the Kids' Dental Dictionary.
