Lidl's electric toothbrush: €16.99 and a three-month lifespan

On 26 August 2013, Lidl put an electric toothbrush on sale for €16.99. The most frequently mentioned alternative was a Braun Oral-B Vitality Precision Clean for €19.75 on Amazon. Two euros of difference that, according to the accounts collected, separate a device that dies after three months from one that lasts for years. The discussion turned to a more uncomfortable question: do you really need a motor to brush your teeth?

The Lidl brush and the replacement problem

The pattern repeats with an insistence that no longer seems like coincidence. One buyer says his Lidl brush stopped working after three months, that he had accumulated two packs of replacement heads, and that when the offer returned six months later, the model had changed and the heads no longer fit. Another confirms he threw his away "after a couple of months of use" because toothpaste got into the gears and jammed them. A third adds that his cracked "after a year and a half or less".

The German brand does not come out well on every front. Some acknowledge that, while under warranty, they were sent a new brush free of charge. The problem comes later: once the warranty expires, no repair is possible. And the replacements, which are the real business of this market, become money thrown away if the model disappears from the catalogue.

Oral-B, Philips and the Mercadona brush: how long each one lasts

Against the Lidl brush, the dominant benchmark is Oral-B. One user reports eight years of use; another, between ten and twelve years with the same device, always on its charging base and compatible with the new heads. The battery, they admit, eventually gives out, but the brush keeps working. That longevity explains why "original and knock-off" replacement heads circulate so easily.

Philips comes up as the alternative recommended by dentists. There is also someone who bought a Mercadona brush for €5.50 with replacement heads at €3.50, and someone who found a USB-charging model on AliExpress for around 10 euros which, he maintains, "beats the Mercadona one by a mile". The price range is enormous and, according to the cases described, the correlation with durability does not always hold.

Does an electric brush clean better than a manual one?

Here the consensus is striking. Those who have tried the electric version agree that the feeling of cleanliness is superior: whiter teeth, healthier gums, less effort for the lazy. One user sums it up with an image: "I was reluctant, and now that I've tried it, I'd never go back to a manual brush. And I say that as someone who cuts the hay with a scythe".

The objections are not about performance, but about risk. One dentist warned a patient that this type of brush "does a lot of damage to the enamel". Another professional recommended the electric brush precisely because the rotating motion avoids the wear caused by manual brushing with straight strokes. The contradiction between specialists remains unresolved in the discussion.

The technical nuance comes from whoever points out that the brush oscillates more than 120 times per second, compared with the two strokes a human hand manages. Leaving the head still on a tooth for five seconds equals 600 strokes. Force is not the problem; technique is.

Water flossers, dental floss and the business of accessories

The conversation drifts towards the oral irrigator, that device that fires a pressurised jet of water. An Oral-B Oxyjet Professional Care model was listed at €57.99, with air microbubbles for "deep cleaning". A Panasonic DentaCare EW1211 appeared as an alternative. The most repeated recommendation: the irrigator complements the brush, it does not replace it, and it can substitute for dental floss in hard-to-reach areas without damaging the gums.

The dissenting note comes from whoever argues that all of this is "nonsense" and that nature did not give us electric brushes. The reply: evolution did not prepare us for streptococcus mutans either, the bacterium that mutated a few thousand years ago and began producing acids that destroy enamel. The naturist argument dismantles itself.

With brushes that last three months and replacement heads that vanish from the catalogue, the question is not whether the electric brush cleans better. It is how long it takes for the initial saving to turn into a recurring expense. Is it worth paying 17 euros every quarter?
