Fluoride varnish
A thin, sticky coating that helps make the outside of teeth stronger. It helps prevent cavities and can help very early decay.
During the visit
The dentist paints it on with a tiny brush. It is quick and does not need a shot. Teeth may feel sticky or look a little dull until the coating is brushed off.
After the visit
Ask when your child can brush and what they can eat. These rules depend on the varnish used. Soft foods are often allowed, but hot or hard foods may need to wait.
Good to know
Varnish does not replace daily brushing with fluoride toothpaste. Tell the dentist about allergies before it is used.
