Floss or interdental brush — which is better with veneers?
Both work — the choice depends on your gap width, and the technique matters more than the tool.
Q. Since getting veneers I am nervous about snapping floss down between my front teeth. Should I switch to interdental brushes? A. Keep cleaning between the teeth either way — just adapt the tool to the space and the motion to the restoration.
Match the tool to the gap
For tight contacts, floss remains the practical choice: ease it past the contact point with a gentle sawing motion instead of snapping it down, hug the tooth in a C-shape, and slide it out sideways if the contact feels sticky rather than yanking upward against the veneer edge. Interdental brushes suit wider spaces and gum-line concavities, where their bristles clean walls that floss barely touches. Many people with veneers end up using both, in different parts of the mouth.
Gap widths differ tooth by tooth and person by person, so sizing an interdental brush by guesswork often means it is too small to clean or too large for comfort. Ask at your next dental visit for a quick sizing — most clinics will map which spaces take which size in a couple of minutes, and check that your floss technique is not stressing a veneer margin.
