What is the ruling on swallowing food remnants stuck between the teeth while fasting?

If food residue intentionally enters the throat of a fasting person, then their fast is broken, and they must make up for it. This is the view of Shafi'i, Ahmad, and Abu Yusuf, and it is attributed to Malik. However, Abu Hanifa said that it does not break the fast. But if it enters their stomach unintentionally, after taking all possible precautions, then there is no blame on them.
