Doing a 24-hour urine collection for proteinuria and creatinine clearance is unnecessary because a spot urine sample to measure urine albumin to creatinine ratio is quite sufficient for diagnosis and therapy. More importantly, exercise, dietary protein, and sustained upright posture tend to increase albumin excretion rates.
As an orthodontist i see many panoramic x-rays of children as young as 8 with the earliest signs of wisdom tooth formation. Teeth take a long time to develop and erupt. Your top front permanent tooth, for example, that came in when you were about 7, began to form before you were born.
The majority of us have most of our permanent (adult) teeth by age 13, followed by our wisdom teeth (third molars), which usually push their way through the gums or become impacted between ages 17-21. After age 21, wisdom tooth removal becomes more complicated. Not everyone's teeth develop on the same schedule.
