Are Smart Electric Toothbrushes Worth the Extra Money in 2026?

A smart electric toothbrush is worth the extra money only if you will use its app or display features every day. Electric Teeth’s advice is that smart toothbrushes are not worth paying extra for unless you are certain you will use the features. The brushes that do the most for cleaning still come down to a pressure sensor, a two-minute timer and a pacer, and those three are found on cheaper models too.

What the table shows about smart models

Electric Teeth’s spec table includes one brush that is clearly a smart model: the Sonicare DiamondClean 9900 Prestige. It is listed with Bluetooth, five cleaning modes, a 28-day battery, 71 dB of noise and $8 replacement heads. Its three-year cost is $410, the highest in the table. The same page lists the Sonicare 4100 at $150 over three years, with one cleaning mode and no Bluetooth. Source: Electric Teeth’s pricing notes. Prices move, so match the figure against the brand’s store before you pay. The prices here were checked on 2026-10-14.

Electric Teeth also names the 9900 Prestige its best technology pick, which is a reviewer’s judgement about features rather than a measured cleaning result. The table does not give a cleaning score for Bluetooth itself.

What smart features actually add

On the brands’ own sites, the smart features are an app and a display. Oral-B’s website describes Bluetooth connectivity that links its brushes to the Oral-B app and Apple Health, and it shows a visible pressure sensor and a two-minute timer on its iO models (Oral-B’s pricing notes). Those are useful if you want coaching or a log of your brushing sessions.

Electric Teeth draws a line between features that matter to dentists and features that are convenience. Its key points say the pressure sensor, the timer and the pacer are the essential features dentists recommend. Its reviewer also notes that the iO range has a more advanced pressure sensor, and that this is something you could skip if you are on a tight budget.

Who a smart brush suits

• Buyers who will use the app. If you want a brushing log, a brushing guide or reminders, a smart model gives you those, and that use is the main reason to pay more.
• Buyers who want the most advanced pressure feedback. Electric Teeth rates the iO range’s sensor highest, so an iO model is the more likely choice for this need.
• Buyers who want a stronger reason to keep brushing. A display and timer can help some people keep a habit, but this site has no data on whether that helps your teeth.

Who should skip the smart upgrade

If you want the three essential features at the lowest price, a non-smart model covers that need. The Sonicare 4100 is the example in Electric Teeth’s table. Its three-year cost of $150 is far below the $410 for the Bluetooth 9900, and it still lists the pressure sensor, timer and pacer. If you have no plan to use an app, the extra money is hard to justify on the table’s own numbers.

Before you buy a smart model

Check whether the app is free, what it requires, and whether the brush works without it. Confirm the replacement head price, because the iO range’s heads cost more than other Oral-B heads according to Electric Teeth. Check that the model you want has a pressure sensor, a timer and a pacer, since those three are the core of the comparison.

Limits of the smart-feature claims

This article does not test any app or measure whether a smart display improves plaque removal. It does not claim that smart features lead to better brushing habits, and it does not give a clinical opinion. The figures come from Electric Teeth’s table and from the brands’ own sites. The rules behind the ranking are in the methodology, and the order itself is on the home page.
