Waiting for Tooth Fairy!!

Most of my friends have lost their milk teeth when they were 5 but I am already 6 years now and am still waiting .All my teeth seems to be strong as bull,no signs of loose tooth yet.It has been more than a year since I made the tooth cast with plaster of paris .I colored them with vibrant colors and took a lot of effort to impress the Tooth fairy .Not sure how long I need to wait .Mera Number kab ayyaga??
