How to Brush Your Teeth the Right Way (Technique Actually Matters)

By Dr. Boris Zusin · Published August 2, 2026

Almost everyone brushes their teeth twice a day. Far fewer people brush them well — and the difference between the two shows up clearly at your next cleaning. Good technique matters more than an expensive toothbrush or the "right" toothpaste.

Use the Right Angle

Hold your brush at a 45-degree angle to the gumline, not flat against the tooth surface. This angle lets the bristles reach just under the gumline, where plaque builds up first and where a flat brushing motion tends to miss entirely.

Use Short, Gentle Strokes — Not Big Scrubbing Motions

Brush in short, gentle back-and-forth or small circular motions, covering just a couple of teeth at a time before moving on. Aggressive, wide scrubbing motions don't clean better — they mostly just wear down enamel and irritate gums over years of repetition, which is a common cause of gum recession and tooth sensitivity later on.

Don't Forget the Back Sides and Chewing Surfaces

Most people brush the front, outer surfaces of their teeth well and shortchange three areas: the inner surfaces (facing the tongue), the chewing surfaces of the back molars, and the very back tooth on each side. Make a habit of covering all three every time, not just the "public-facing" surfaces you see in the mirror.

Brush for the Full Two Minutes

Most people brush for well under a minute without realizing it. Two full minutes — about 30 seconds per quadrant of the mouth — is what it actually takes to clean each surface properly. A timer, a phone app, or an electric brush with a built-in timer all help close this gap.

Brush Twice a Day, and Wait After Eating Acidic Food

Twice daily — morning and before bed — is the standard recommendation. If you've just eaten or had something acidic (citrus, soda, wine), wait about 30 minutes before brushing; acid temporarily softens enamel, and brushing too soon can wear it away faster than it would otherwise.

Replace Your Toothbrush Every 3 Months

Bristles splay and lose their effectiveness well before they look obviously worn out. Replace your brush (or electric brush head) every three months, or sooner if the bristles are visibly frayed or you've been sick.

Technique is something we're always happy to walk through chairside at your next cleaning — small adjustments here make a real difference in how your teeth hold up between visits.
