How to Brush Your Teeth Properly: Technique, Timing and Tools

Brush your teeth twice a day for at least two minutes, using a fluoride toothpaste and a soft-bristled brush angled at 45 degrees towards the gumline, with small, gentle circular movements. The aim is to be thorough and systematic, giving every surface equal attention, rather than scrubbing hard.

Many patients brush every day and still develop decay, bleeding gums or tartar. The cause is usually not how often they brush but how they brush. Below is the method dentists recommend, along with the mistakes we see most often.

Step-by-step brushing technique

A widely recommended approach is the modified Bass technique, which focuses on the area where the tooth meets the gum, as this is where plaque collects most.

• Apply a pea-sized amount of fluoride toothpaste.
• Place the bristles against the gumline at a 45-degree angle.
• Use small vibrating or circular strokes, covering two or three teeth at a time.
• Clean the outer, inner and biting surfaces in a set order so nothing is missed.
• For the inner surfaces of the front teeth, hold the brush upright and use up-and-down strokes.
• Finish by gently brushing your tongue from back to front.
• Spit out the excess toothpaste but do not rinse with water, so the fluoride stays on your teeth for longer.

How long and when should you brush?

Aim for at least two minutes, which works out at roughly thirty seconds for each quarter of the mouth. A timer, or an electric toothbrush with a built-in timer, makes this much easier.

Brushing last thing at night matters most, because saliva flow drops during sleep and bacteria multiply more freely. After acidic food or drinks such as fruit juice or fizzy drinks, wait around 30 to 60 minutes before brushing, as enamel is temporarily softened and more prone to wear.

Manual or electric toothbrush?

Both can clean teeth well when used correctly. Research suggests that oscillating-rotating electric toothbrushes may reduce plaque and gum inflammation slightly more than manual brushes.

Electric brushes are particularly helpful for people with limited dexterity, those wearing braces, children and anyone who struggles to brush for the full two minutes. Models with a pressure sensor also warn you when you press too hard. If you prefer a manual brush, choose one with soft or medium-soft bristles and a small head.

When should you replace your toothbrush?

Replace your toothbrush, or your electric brush head, roughly every three months. Do it sooner if the bristles are frayed, splayed or faded, because worn bristles remove plaque far less effectively.

It is also sensible to change your brush after a cold or throat infection. After use, rinse it, store it upright and let it air-dry rather than keeping it in a closed case.

Common brushing mistakes

Using a hard brush or pressing too firmly can, over time, contribute to gum recession and wear at the necks of the teeth. Concentrating on the front teeth and neglecting the back molars is another frequent problem.

Brushing alone does not clean between the teeth, so floss or interdental brushes should be part of your routine. If your gums bleed, your teeth feel sensitive or bad breath persists despite regular brushing, see a dentist. You can book an examination with Dr. Merve Hakan, who can also check your brushing technique.
