Some people worry that regular flossing can push teeth apart. Correctly used floss is a thin cleaning tool, not an appliance that applies continuous orthodontic force.
Why might a gap appear larger?
More thorough cleaning can remove trapped debris or deposits. Reduced gum swelling can also change how a space looks. A genuinely new gap, tooth mobility or receding gums should be assessed by a dentist.
Do not use excessive force
Floss should not be forced aggressively. Its purpose is to clean the side surfaces of the teeth gently.
When is a check-up needed?
Changes in tooth position, exposed tooth necks, pain or persistent bleeding require professional assessment and should not automatically be blamed on flossing.
