Unfortunately this attitude

I then pretended I still believe in the Tooth Fairy until the rest of my teeth came out.

is how you get tenure.

But in humility I think my teeth started coming out a fair bit later than most children's do. And I don't know how conscious I was of what I was doing. I'm not sure the thought process was as complicated as "I know, I'll keep it a secret from my parents, who I suspect of being the tooth fairy, and if there is no money I'll see what happens if I do tell them." It may just have been hard to get excited about announcing I lost another tooth after already having done it 4 times before.
