Dent 
To dream of a dent in your car or in a treasured object implies a small and short-lived disappointment may have just occurred. Alternatively, someone may have made a comment about your looks or age, pushing a 'vanity button' and resulting in a 'dent' to the ego.
Dentist
To dream about being at a dentist's office suggests that there is occasional concern about the honesty of someone close to you. You may sense that something's not quite right with them, but in the long term, this concern will benefit you.
To dream that someone else is being worked on by a dentist indicates that impropriety will surprise you, especially when it strikes close to home.
Dentures
To dream of dentures in your mouth suggests a family reunion that may hold unexpected news. It may feel as though it is your responsibility to provide for your family at all times but a dream of dentures is a message to take a break as it is acceptable to allow your loved ones to fend for themselves.
Dental Floss
To dream of dental floss indicates that the time is right to address some responsibility issues in your waking life. People may be surprised and defensive by overly expressing for themselves instead of remaining quiet. Stick with it, as you will emerge true to yourself.
False Teeth
To dream of false teeth indicates that you may be assuming responsibility for somebody else's actions in order to distract from your own short comings. False teeth in a glass of water suggest it may be time to strip away the unnecessary in your life and focus on important aspects only. To dream of false teeth falling out in public shows a high level of confusion, anxiety and the need to breathe more deeply in your day to day living.
Orthodontist
An orthodontist in a dream represents worry about your control over others' perceptions of you. To have an adjustment at the orthodontist in a dream indicates your need to reevaluate the signals you give to others.
