The boy was in gym class Monday when the incident happened, WKMG-TV, Orlando, Fla., reported.
"He went in to have a drink and when he went to pull it away from his mouth, it just sucked his tongue in," said his mother, Ebony Gibson. "My heart just dropped. It just dropped."
Doctors had to surgically remove the aluminum bottle from the 11-year-old's tongue.
"His airways had swollen up so badly and his tongue swollen up so badly, he couldn't breathe on his own," Ebony Gibson said. "He's very scared."
Doctors said it's likely that Demetrice will make a fully recovery.
Gibson said she plans on removing all of the aluminum water bottles from her home.
"If you have them in your home, please throw them away, get rid of them," she said.
