Dentiguard Power Toothbrush

Last Updated:

Dentiguard Powered ToothbrushIn recent years, Aldi has added an electric toothbrush to its Special Buy rotation. (This is not to be confused with the more deluxe Dentiguard Rechargeable Sonic Toothbrush.) I remember being intrigued the first time I saw these on the shelves, but also a little concerned. At my last cleaning, my dentist had suggested an electric toothbrush, but the ones he tossed out were expensive, some more than $100. The Aldi electric toothbrush, meanwhile, was less than $5. The price was so low that I immediately wondered what the catch was. If I use this, am I somehow more likely to get cavities? I figured it was going to be inferior to the expensive ones in some way — it had to be — but how, exactly?

Eventually, I gave in and took the plunge. In fact, I ended up buying two of them across two years. Here is what I learned.

The Dentiguard Power Toothbrush comes with the toothbrush and four brush heads. The brush heads are very easy to swap out. The bristles, according to the package, are made by DuPont. (You can get soft or medium bristles. I went soft.) The brush heads are meant to last three months, so with what’s in the package you’re good for a year. It’s supposedly possible to order replacement heads, but I would guess it’s probably cheaper just to get a new toothbrush every year, which is what I did.

The toothbrush is powered by AA batteries. I went through the original batteries pretty quickly, as well as a second pair of batteries. For the third battery set, I used a pair of Energizer Ultimate Lithium Batteries, which are designed for higher power devices like digital cameras and other electronic devices. The Ultimate batteries lasted a lot longer than the others, and that would be what I would suggest if you don’t want to mess with replacing the batteries every few weeks. No matter how you slice it, though, you’ll probably pay more for batteries than you do for the toothbrush.

So … does it clean? I thought so. Between the design of the bristles and the movement of the brush head, I felt like it did a pretty thorough cleaning. You pretty much just hold the brush over your teeth and gums and let it do the work.

The true test came with my dentist. Good news there: I had no cavities or other dental problems in the time I used it, so the toothbrush appears to do what it’s supposed to do. (I could never own up to the dentist that I had entrusted my teeth to a $5 powered toothbrush, though.)

After the first year using up the heads on my first toothbrush, I liked it enough that I bought a second. However, a little over halfway into the second brush’s life, it stopped working. To be fair, the brush comes with a one-year warranty, but I didn’t go that route so I can’t speak to whether the warranty process is worth it.

The Verdict:

For an absurdly cheap price, we found the Dentiguard Power Toothbrush to be effective at keeping the cavities away, although it can drain conventional batteries quickly. We also had mixed results with reliability, although the toothbrush does come with a warranty.

  1. My dentiguard worked until I had to change the batteries!!! Anything I can do to make it work again or please just replace it. Didn’t save receipt. Worked fine on my teeth.

    • I feel your pain. If you have the packaging you can try calling the support number, but you might have to replace it.

    • This happened to me twice. Both toothbrushes worked fine until it was time to replace the batteries. First I thought it was a fluke with the first toothbrush, but when I encountered the same issue with the second battery I got really annoyed. Is this a predetermined end-of-life product cycle? And, of course, the price of the product is such that it isn’t worth the time to pursue remediation. Frustrating!

    • I have a dentigaurd that just died. Dead. I have changed batteries twice, that ok. And new heads are inevitable. But the whole thing dead??!!
      I purchased in an effort to avoid plastic toothbrushes, one item that tons of the plastic washes on our beaches. Now I have to start over?
      What?

  6. I have purchased this every time they had it for the last several years. It is worth the price for the replacement heads alone. I have only had one toothbrush to stop working. It is a great buy and good toothbrush.

  7. How to change brushes

  8. I just bought two and in a months time one stopped working, I changed the batteries and it still doesn’t work. I don’t have the receipt and am very disappointed. I thought this was a good buy because it came with 2 replacement heads

  9. I’ve been using my original handle for at least 4 years. I swap heads very rarely because I don’t push too hard to wear it out. My better half has hers stop working once in a while but I’m able to get it to work again by using a tweezers to manually turn the spindle with the brush head removed. I once put a tiny drop of 3 in 1 oil on the spindle and that helped a lot. (I had to remove the motor from the inside which is very simple to do with a needle nose pliers.) Mine has never seized up but I am very thorough when cleaning it. Hers has finally bit the dust and we are waiting for Aldi to get them in again since they are not always on the shelf.

  10. I have a dentiguard advanced dual motion model1714. I don’t remember when I bought. But, a couple of weeks back I found from my lost treasure. It didn’t work. I replaced with new batteries and still don’t work. Any suggestions, please.

  11. Guess I should be thrilled that my dentiguard toothbrush worked for about three years, maybe a bit more! It plugs in, though, no batteries to replace which I like. Wish I would have bought another one when they were available a few months ago. I think the price was around $25.00, not $5.00. Silly me thought that was expensive until I checked out the others (kept under lock and key @ the Ingles grocery store!).i didn’t change the brush heads as frequently as recommended and still have three left. I think six were included. Maybe I’ll try the repair method mentioned earlier. In the meantime I brush my teeth with the dentiguard and a bit of old fashioned elbow grease. Works better than a manual brush because it’s easier for my crippled hand to grasp. Perhaps I should have unplugged it while I was away for just under 14 days because it had died during that time (due to loneliness, neglect, boredom?….it won’t say…)

    Hello, I have a dentiguard toothbrush which i purchased about 6 months ago. Now, it doesn’t work. I have changed the batteries and it still doesn’t work. I would like a replacement please.

  13. Well my toothbrush did not even make it through the first battery change. Used it two weeks and thought the batteries were dead, but tested the batteries and they were fine. I now have a slightly used brush and two new ones with now way to use them. It worked fine when it was working, but it is no good to me now. Can you send me another one to try?

  14. These toothbrushes are nearly junk. They work great at first but seize after about three months. I managed to open them up and free up the motor in two of them, but they don’t work as well. One of them seized up again. I did not save the receipt. I did contact the manufacturer and never received a response. I will never buy Dentiguard again!

  15. So I read many comments about the dentiguard power toothbrush I purchased at Aldi… Love 😍 it till I had to change battery & now it’s not working… I DON’T understand why we have to wait till Aldi runs special again, why can’t we get a replacement if there r many that have same issue?!!!

  16. I have the rechargeable one that you plug into a wall outlet. I had one before which died before I ran out of brushes. Of course I didn’t have the receipt. You’d think the brushes would fit this model, but noo… that would make too much sense. Anyway, they’re cheap enough so that I bought two of them this time.

    • PS: I think I paid around $25.for the first one several years ago (more than 5, for sure) and then kept waiting and looking and looking and waiting for them to appear again. This time I think I paid less than $20 for one. Certainly II never saw one for $5.00!
