How Long Do Electric Toothbrushes Last?
'How long does it last' can mean two things for an electric toothbrush: how long the battery runs between charges, and how many years the brush itself survives. Here's the answer to both.
Quick answer
A good electric toothbrush lasts around one to two weeks of normal use per charge, and the brush itself typically lasts three to five years before the battery starts to fade. Replace the brush head every three months regardless, as worn bristles clean poorly.
Battery life per charge
Most rechargeable electric toothbrushes give roughly one to two weeks of brushing (two minutes, twice a day) on a full charge, which is handy for travel. Premium models can last three to four weeks. A full charge takes several hours to overnight. Battery life shortens over the years as the internal cell ages.
How long the brush lasts
The toothbrush body usually lasts three to five years. The limiting factor is the built-in rechargeable battery, which slowly holds less charge over time until it needs charging every few days. Motors and electronics generally outlast the battery. Looking after it - keeping it dry, not leaving cheaper models permanently on charge - helps it last.
When to replace it
Replace the brush head every three months, or sooner if the bristles splay or the indicator bristles fade. Replace the whole toothbrush when the battery no longer holds a useful charge, the motor weakens, or it won't charge - typically after a few years. If only the head is worn, you just need a new head, not a new brush.

Frequently asked questions
How often should you charge an electric toothbrush?
When the battery runs low - usually every one to two weeks with normal use. Follow the manual; some models are happy left on the charger, others last longer if you charge only when needed.
How many years does an electric toothbrush last?
Typically three to five years. The rechargeable battery is usually what wears out first, holding less charge over time until it needs charging every few days.
How often should you change the brush head?
Every three months, or sooner if the bristles splay or the colour indicator fades. Worn bristles clean far less effectively.
