Position the brush at the gumline

Stand in front of a well-lit mirror so you can clearly see what you are doing. Hold the handle of the brush gently, much like you would hold a traditional toothbrush or a pen. Guide the tip of the brush toward the gap between two teeth, holding it at a slight angle that matches the natural slope of your gums.

Avoid jamming the brush straight in at a harsh ninety-degree angle against the gum tissue, as this can cause discomfort. Instead, aim the bristles just beneath the contact point where your teeth touch.

Take your time during this positioning phase to ensure you do not slip and poke your gums.

Glide gently through the gap

Let the bristles do the work as they move horizontally through the gap. You should not twist, spin, or aggressively saw the brush back and forth, as this can bend the wire or damage the delicate gum tissue surrounding the teeth.

A single complete pass—moving the brush inward through the gap and then pulling it back out—is generally sufficient for each space during a daily cleaning session. If the gap is particularly wide, such as those sometimes found around dental bridges or orthodontic appliances, you might make a very slight lateral motion, but the core movement should remain smooth and controlled. Keep your hand steady and maintain a relaxed grip to avoid applying too much pressure against the teeth or gums.

Move systematically around your mouth

To ensure you do not miss any areas, establish a consistent path to follow every single day. Many people prefer to start on the upper arch, working from the back molar on the right side all the way around to the back molar on the left side, and then repeating the exact same sequence on the lower arch.

As you move from space to space, pay attention to how the brush feels. If you transition to a noticeably narrower or wider gap, pause and switch to a different size brush to maintain the proper fit. Rushing through this process often leads to missed spots or accidental trauma to the gums. By working methodically from tooth to tooth, you ensure that every accessible interdental space receives the same level of attention.
