Quietest Electric Toothbrush in 2026? Noise Levels Compared

The quietest electric toothbrush in Electric Teeth’s 2026 spec table is the SURI 2.0, at 54 dB. The Sonicare 4100 is next at 60 dB, and the loudest brush with a listed noise figure is the Oral-B Pro 1000 at 73 dB. Noise is one of the few things you can compare across brands from one table, but a lower number does not tell you how well a brush cleans. Source: Oral-B’s tier list.

Noise levels in the table

Source for every noise and price figure in this table: Electric Teeth’s review summary. The page also lists a separate quietest-brushes guide, which this article does not reproduce. Prices change, so confirm the current listing on the official product page before you buy. The prices here were checked on 2026-10-14.

What the numbers mean

Decibels are measured on a logarithmic scale, so a gap of a few decibels is easier to hear than to read off a chart. The table gives one figure per brush, with no range and no description of how the reading was taken, so the figures are best used to rank brushes against each other rather than to predict the sound in your bathroom.

Electric Teeth reports that the iO3 peaked at 64 dB during its own testing. The review describes the Pro 1000 as noisier than the other top picks. Those descriptions match the figures in the table. Source: Electric Teeth’s rate sheet.

Who should care about noise

• Light sleepers and shared bathrooms. If the brush runs near a bedroom wall, the SURI 2.0 and the Sonicare 4100 are the two quietest options in this table.
• Households with children. A quieter brush can make brushing time easier for a young child who dislikes the sound, but the table does not test that effect.
• Buyers who only care about price. The Oral-B Pro 1000 and the Philips One have the same three-year cost on the table, about $95 each, so a noise-first buyer can pick the quieter Philips One’s 71 dB over the 73 dB Pro 1000 without paying more. Source: Oral-B’s cost roundup.

What noise does not tell you

A quieter motor is not the same thing as a better brush. Electric Teeth ranks the SURI 2.0 as its Editor’s Choice for reasons that include its environmental pledges, its travel case and its handle, and noise is not the main reason. The review also says the Sonicare 4100 offers low and high power settings that feel gentler on the teeth and gums. Those points sit outside the noise column.

The table also does not show whether the brush head is quieter or louder when pressed against the teeth, and it does not record the sound of a particular brush in a particular room. Treat the figures as a way to narrow your list, not as a final answer.

Before you buy

Check the noise figure against the model number, since some brands sell several versions with different motors. Confirm the price and the head cost on the official product page. If noise is your top concern, give the SURI 2.0 and the Sonicare 4100 first look, then compare their price and battery life.

Where the noise data stops

This article runs no sound measurements of its own, and it does not claim that any brush is quieter in every room or at every power setting. It does not say which brush cleans better, and it does not treat noise as a health feature. For the full ranking and how the brushes are scored, see the 2026 ranking and the methodology page.
