A dentist  helps treat and prevent diseases and conditions in the mouth.
i need to see a dentist. it's been a while. i'm just so afraid of dentists
There is nothing to be afraid of. A dentist has plenty of support staff such as dental hygienists and techs to help you feel better.
i know. Do you know what kind of equipment dentists use?
Sometimes it is necessary for them to use nitrous oxide to make a patient feel more comfortable. Maybe that would help you with your fear.
what is nitrous oxide?
It is a chemical gas that is useful as an anesthetic and for pain relief.
oh. Is that what people call "Laughing gas"?
Yes it is commonly referred to as laughing gas.
okay that makes sense
