When Sabrina Grant read the email from a teacher's aide at Woodrow Wilson Elementary School in Framingham, Massachusetts, she was furious. The aide said Grant's 10-year-old autistic son kept playing with one of his loose baby teeth. The aide added it was very distracting, so they yanked the tooth out. Grant got even even angrier when her son got home. She found the loose tooth was still in his mouth, but a molar next to it was missing.
