In brief: Two weeks.
Major depressive disorder usually is not formally diagnosed unless symptoms are experienced for the majority of a two-week period.
Plus the symptoms cannot be attributed to bereavement, drug use, etc. And must include depressed mood most of each day, wt loss, sleep changes, fatique, poor mental function, suicidal thoughts etc, and not attributable to other issues ie anxiety, adhd, etc...

In brief: Don't wait
If a teen is unhappy unless it is very transient, it is always important to understand the source and work on coping strategies.
A persistent pattern or several weeks is a mandate for professional evaluation. However yoiur showing interest in theri well being is essential regardless of time span.

In brief: Any extended period
Being a teenager is a difficult period in the best of times.
If there is any period of unhappiness continues, speak to your pediatrician to help whether this is time for a referral to a psychologist or psychiatrist.

In brief: Not long
Although the diagnostic manual says depression should be diagnosed after two weeks, if your teen's function is severely effected or if suicidal ideation develops quickly, get your teen psychiatric help as soon as possible.
