Use a water flosser following the tooth brushing. The entire routine of oral care is normally "brushing first, then flossing."
Brushing: This is the first cleaning step, wherein the toothbrush scrapes away the majority of food particles, soft deposits, and plaque from the surfaces of teeth and between teeth by mechanical friction.
Water flossing: This is an adjunct deep-cleaning treatment. The wide, high-speed water jet reaches into locations inaccessible to a toothbrush, such as interdental areas, gum pockets, and interproximal space around orthodontic appliances, and dislodges residual debris and bacteria.
Post-meal quick cleaning: If you have to clean your teeth immediately after meals, you can start with the water flosser to remove the larger chunks of food and brush afterwards to prevent allowing the junk to sit stuck in between teeth for so long.
Orthodontic/Implant users: For those wearing braces or implants, it is recommended that a water flosser be used after meals before brushing. This will help prevent food particles from causing gum inflammation or infection around the restoration.
