IV. Does this mean you can't brush horizontally at all?

In fact, many people unconsciously use a combination of methods when brushing their teeth. The key is not to completely prohibit horizontal brushing, but rather—don't make horizontal brushing your primary method, and definitely don't brush horizontally with force.

For example, when cleaning the chewing surfaces (the sides used for biting), gently brushing horizontally is fine, as these surfaces are relatively flat.

However, on the outer sides of the teeth and near the gums, it's best to brush vertically or at an angle.

V. Many people's brushing problems aren't just about direction.

At this point, you might think: "Oh, it's because I'm brushing in the wrong direction!"

But actually, direction is only one factor. Several other equally important points are:

1. Too much force

Some people brush their teeth like they're "brushing shoes," feeling more secure the harder they brush. But teeth aren't cleaner the harder they are; in fact, they're more prone to injury.

2. Too little time

Many people finish brushing in less than a minute, which is far from enough. It's generally recommended to brush for at least two minutes, and to brush different areas slowly.

3. Neglecting the gaps between teeth

No matter how diligently you brush, if you don't clean the gaps between your teeth (e.g., with dental floss), there will still be many hard-to-reach areas.

4. Inappropriate Toothbrush Selection

Toothbrush bristles that are too stiff or a brush head that is too large will affect brushing effectiveness and are more likely to damage gums.

VI. How to Adjust Your Brushing Technique?

If you've always brushed horizontally, you don't need to change it completely all at once; you can adjust it gradually.

Try this:

Start with one side of your teeth. Use the Bass brushing technique, a modification of vertical brushing. Simply put, it's a 45-degree angle + small vibrations + brushing in the direction of the teeth, combining the advantages of horizontal and vertical brushing while avoiding their disadvantages.

Use small up-and-down or circular motions instead of large horizontal brushing motions.

Pause briefly on each tooth; don't just glide over it.

Finally, gently brush the chewing surfaces. The specific method is simple: Use a soft-bristled toothbrush, aiming the bristles at the junction of the teeth and gums at a 45-degree angle. Gently press the bristles into the gum line, then make small horizontal vibrations 4-5 times, and then brush downwards (upper teeth) or upwards (lower teeth). Brush the chewing surfaces horizontally and the inside of the front teeth vertically. Apply pressure until the bristles are slightly bent, causing no pain or bleeding. Brush for at least two minutes each time, ensuring all surfaces are clean.

You might feel a little uncomfortable at first, but it will become much easier after a few days.

VII. The Core Difference Between Horizontal and Vertical Brushing

In the long run, vertical brushing (or the scientific brushing method) is more beneficial for protecting teeth and gums, reducing sensitivity and bleeding.

Many oral health problems don't occur suddenly, but are gradually caused by accumulated small habits. Brushing your teeth seems ordinary, but if done incorrectly, even twice a day for several years, the effects will be noticeable.

Instead of waiting until your teeth start to feel uncomfortable to remedy the situation, start now and brush your teeth correctly.

After all, teeth, if used well, can last a lifetime; if used poorly, they can cause serious problems.
