Why is a sonic toothbrush better than an electric one?

Since sonic toothbrushes entered the market, an ongoing debate has emerged between them and traditional electric toothbrushes with round brush heads. Both types have their loyal users, but experts clearly point out that sonic toothbrushes outperform their older counterparts in many key areas. What are these areas? Why are sonic devices gradually replacing classic electric toothbrushes? Let’s take a closer look at how both tools work. If you’re still asking yourself which is better—a sonic or electric toothbrush—this article is for you.

Sonic vs. electric toothbrush – what do they have in common?

Before diving into the differences, it’s worth noting what sonic and classic electric toothbrushes have in common. First, the appearance—both types usually feature similar handles with removable brush heads. They’re lightweight, ergonomic, and powered by internal electric motors that generate movement. Both sonic and electric toothbrushes can be powered by batteries or rechargeable systems, with the latter being far more common. They also offer a similar number of brushing modes, functions, and user-friendly features.

How is a sonic toothbrush different from an electric one?

This is where the similarities end. The first major difference lies in the brush head design. Sonic toothbrushes use elongated brush heads, similar in shape to those found on manual toothbrushes. Traditional electric toothbrushes, on the other hand, feature round heads because they work using rotating movements. Another significant distinction is in how they clean. A sonic toothbrush uses sweeping motions and sound waves to remove bacteria, while an electric toothbrush relies on mechanical abrasion by rotating around its axis repeatedly.

Why do specialists recommend sonic toothbrushes?

For several years now, sonic toothbrushes have been the most recommended devices by dental professionals for everyday oral hygiene. But why is the sonic toothbrush better? There are several factors behind this recommendation.

Superior cleaning effectiveness

This is the most important advantage sonic toothbrushes have over electric ones. First, sonic devices operate at much higher frequencies. For instance, Smilesonic toothbrushes generate up to 96,000 vibrations per minute, compared to a maximum of 10,000 rotations and 40,000 pulsations from traditional electric toothbrushes. This directly leads to a more thorough removal of bacteria from the oral cavity. Second, thanks to sound wave technology, a sonic toothbrush can also clean the spaces between teeth, unlike standard electric brushes.

Larger cleaning surface

Due to their oval shape, sonic toothbrush heads can cover a larger area of the tooth during brushing. This means each motion removes more bacteria from the enamel. A larger cleaning surface is especially beneficial when brushing molars, which can be harder to reach with a traditional electric toothbrush.

Greater safety

Mechanical abrasion used by electric brushes with round heads can sometimes be harsh, potentially damaging the teeth. Sonic technology is much gentler. The bristles barely touch the enamel, while harmful microorganisms are flushed away without direct scraping. For this reason, sonic brushes are ideal for people with sensitive teeth or gum conditions.

Easier and more comfortable brushing

Experts confirm that brushing with electric toothbrushes takes more effort and focus. With a round-headed electric brush, you must carefully clean each tooth individually, gently pressing the bristles against the surface. In contrast, a sonic toothbrush simply needs to be glided along the dental arch—the brush does the work for you.

Quieter operation

Sonic toothbrushes are much quieter than traditional electric brushes, despite being more powerful and efficient.

Are sonic toothbrushes worth it?

Absolutely. Sonic toothbrushes are growing in popularity worldwide. According to dental professionals, the future of oral care belongs to these devices. You can purchase advanced sonic toothbrushes directly from the official Smilesonic website.
