how often do you have to replace the brush ?

The suggested replacement rate is every six months, but I replace it every three. Using the special covers that supposedly clean the brush while not in use, I find that black spots appear in the brush head if I don't switch it out after about 3 months.

It can last up to almost 2 weeks if you brush 2 times a day for the 2 minutes you need to

I replace my brush head about every 4 to 6 months depending on wear. The only bummer is each head costs like $10.00 to $12.00 (retail) but that won't stop me from using my Sonicare. I think the 4 pack at Costco is like $29.90something or other. That's a heck a lot more than I ever spent on regular toothbrushes but man these puppies do their job! I get the 4 pack replacement heads at Costco when available. The only other maintenance you need is that you need to clean the head completely by taking it off an cleaning the head (screw on base) inside and out (from leftover dried toothpaste foam) usually where the head screws on, inside the head, and on the outside where the brush attaches to the screw on head regularly. You should also wash the electric handle. It can be immersed with no problems. The old style toothbrush is perfect for cleaning the inside of the head and the thread. It uses induction to transfer electricity so nothing to short circuit washing the handle. That's about it for maintenance. EDITED for better coherence.

No. I personally have been using this brush for 4 years and it has held up surprisingly well. Thank you for your inquiry.

I've used about ten times, & after the third time, it started loosing hairs, I haven't seen it loose anymore hairs as of lately, I like the brush.

You should replace the brush head every three months or sooner if the bristles look worn down.

I would say they last a couple of years at least. The only issue over time is that the little balls on the end of each bristle eventually come off and then the bristles are very scratchy! Otherwise I LOVE these brushes!

If you have tried the suggestions from others who responded to your question, I would contact the manufacturer. Be sure the brushhandle is fully charged and the brush is attached fully to the handle. They only last about 3 or 4 months before being replaced if you use the brush even once a day then gradually slow up in rotation. This is the signal to replace the brush.

Mine lasts for about 2 months easy. My setting is "Clean" so it runs for 2 minutes each time I brush.

If you don't mind softer brush you may use one head for 2-3 months. Dentists recommend 1 month

I have yet to find replacement brushes--but I have had mine for 6 months--still good--doesn't smell--still works great

I've had it for a while now and I use it about 2 to 3 times per day. So far no bristles have fallen off and from the way my brush looks I doubt the bristles would ever really "fall off". If anything I think the bristles would only come out if you purposely violently smashed the brush around till the surrounding area breaks or literally yank out one of the bristles with a tool of some kind.

A LONG time. It was years before I had to replace mine, but I don't use it every day. Maybe a couple times a week is all.

They're great brushes, but two years is as good as it gets. Time to buy a new one I'm afraid!

Sonicare says replace every 6 months maximum. Depending how often you brush, the force you use against your teeth, and the number of people using the brush (for those who like to share), it varies. I've been replacing mine every six months or so. A two pack lasts a year and is generally cheaper to buy than a single brush head. Don't be afraid to rinse the brush head under water to clean it. Let it dry before you use again. Never immerse the handle/body in water, however.

Brushes have a life span. If you overuse them they do wear out. I have had this equipment for years and have had no issues with the brushes or pads.

A few weeks, I think they suggest replacing it every two weeks, but I've used it for six weeks with no complaints from my pup. Depends on weather and usage I would guess also.
