Ambiano Power Toothbrush (Dentiguard Power Toothbrush)
This post contains affiliate links.
EDITOR’S NOTE: We bought this toothbrush in 2024. Aldi sold power toothbrushes again in July of 2025 for $4.49 and in December of 2025 for $4.99. Aldi used to sell this under its Dentiguard house brand. As of December of 2025, it’s sold under the Aldi Ambiano house brand. See our update at the end of this post with info about how the toothbrush has held up during the past year.
There are many things in life that people just have to suck up and do. Taxes. Work. Bills. The basics. These things are necessary, if not always fun. Health care is also necessary, and it comes with its own set of headaches.
Going to the dentist, though, carries its own special mystique … and by mystique, I mean that people dislike it enough to use it as a figure of speech. “This is about as exciting as going to the dentist,” they might say. Or “this is as painful as a root canal.” It’s like dentistry is a line of torture that all other tortures are judged against.
Yet we know that good dental hygiene is crucial. Research has shown that poor oral care can create problems throughout the rest of the body. Taking care of your teeth and gums is an important part of overall health.
Aldi has been selling toothbrushes of various kinds for years, from standard brushes as Regular Buys to limited-time sonic models and even kids’ brushes. (No floss, though: don’t get me started on that.) We’ve test-driven many of those brushes over the years. In fact, one of our first posts in 2016 was about the Dentiguard Power Toothbrush, a battery-powered electric version.
Aldi has continued to sell that same toothbrush just about every year. That’s why, eight years later in 2024, we decided to pick up another one to see how the brushes have held up.
The Dentiguard Power Toothbrush is a longtime Aldi Find. Each time it shows up, it is only in stores for a short time, and once it’s sold out, it won’t be back again until Aldi brings it back. Over the last couple of years, it has shown up in stores roughly once every six months, typically in July and December. You can’t order it online from Aldi if it’s out of stock at your local store.
The brushes come in a mixed case with a choice, in 2024, of soft or medium bristles. As the American Dental Association has long recommended soft bristles, that’s the way I went. In 2025, these toothbrushes appear to only be available with medium bristles.
In June of 2025, this toothbrush cost $4.49, and as of December of 2025 it’s $4.99. When we bought this with our own funds in 2024, the toothbrush cost $4.99. With the exception of the summer of 2025, the brushes have been $4.99 since 2016, although years ago this Aldi toothbrush came with four brush heads, while today it comes with two. Because a typical brush head lasts three months, this is a toothbrush that will need replacing every six months, which, as we pointed out before, is how frequently Aldi now sells them.
Despite the reduction in replacement heads over the years, the price point of the Aldi brush is a fraction of what most electric toothbrushes run and is on the low end of battery-powered ones.
As advertised, it comes out of the box with the toothbrush (already loaded with two AA batteries) and one extra refill. The back packaging does not list a warranty but does offer after-sales information through Perrigo, a company specializing in private label pharmaceuticals. The back also notes that the toothbrush is made in China.
It’s … well, it’s an electric toothbrush. The head has a round component that oscillates like other electric brushes, and it also has a bottom bristle that moves back and forth.
It’s a serviceable enough toothbrush, if not spectacular. The bristles are soft and they do oscillate, which seems to help with getting in and working both the teeth and gums. It’s not maybe as vigorous as my Oral B Pro 1000 Rechargeable, but it does move.
At this price point, you don’t expect many frills and you won’t get any. More expensive electric toothbrushes will have timers and pressure warnings. This one doesn’t. It’s just a power toothbrush, plain and simple.
The Verdict:
At the end of the day, what toothbrush you use will depend on your needs and what your dentist says. Aldi does sell a budget electric toothbrush that oscillates and vibrates. It appears to be made by Perrigo, a well-known private label company in the pharmaceutical space. For about $5, this brush comes with two heads, making it good for about six months. What’s more, if the batteries die, they’re easily replaced with a pair of AA batteries. If you need a budget electric toothbrush, this is just that.
UPDATE (12/7/2025) — We still own this toothbrush after a year and it’s fine, but we rarely use it. Instead, we use an Oral-B due to personal dental considerations.
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?
I bought three
im 84 & still heve my teeth
gave two to friends.. bought at aldi $6.99 ea. / weekly sale over
id like to buy a few. how can I mnanage this purchace?
i have the question as jim did. where can i get more & more heads?
Regarding the toothbrush, you can only get them when Aldi runs them as a Special Buy. I don’t know of any way to get replacement heads other than what is in the package.
Thanks
wow I love these toothbrushes at 4.99 at Aldi’s! No problems! where can I find more?
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.
I clean my teeth manually with a toothbrush using toothpaste..
Swish Rinse with water and then polish my teeth with baking soda using the Dentiguard.. rise w a mouthwash!
Love it!!
How to change brushes
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
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.
extremely helpful, though still did not get itt to work…will try removing the brush!
Thank you!! I was having the same problem but I used tweezers to manually turn the spindle and it works again!
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.
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…)
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!
store the tip down or at least horizontal so water will not drain down into the motor. Shake it out after use.
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?!!!
Look down inside. There is a + and a – to tell which way to insert the batteries. You may have I settled them backwards. It won’t work if batteries aren’t in right.
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!
I purchased a dentgaurd power toothbrush a while back, i did not use it until this year. The first time i had to change the batteries ,it worked for two days . The casing became so hot , i turned off and was never able to use it again. my dentist gave me good reviews while was using it. PLEASE HELP|||||
Been using this toothbrush for several years….never had a problem and my dentist was so pleased with my 6 months checkup…..need to get extra brushes soon
I had the same problem when I changed the batteries on my Dentiguard electric toothbrush. I would not give up until I solved the problem.
It appears that both batteries should go in the same way, but they don’t.
Put one in with the positive facing up and the negative down.
Works fine now!

The Dentiguard looks a lot like the Arm & Hammer Sprinbrush. Are the brush heads the same? Anyone tried the Dentiguard brush headson a Spinbrush and vice versa?
I as well bought and tried the Dentiguard electric toothbrush. What a piece of junk. I purchased it from Aldi and didn’t keep the receipt or packaging. Now with the COVID 19, I doubt Aldi would have given my money back anyway. Don’t purchase this item unless you have money to throw away.
Aldi has lifted its pandemic return policy and should be taking returns like normal. https://www.aldireviewer.com/aldi-quietly-lifts-its-pandemic-return-policy/
I bought a Dentiguard toothbrush about two years ago and love it. To keep from having to constantly change batteries, I use rechargeable batteries. I recharge them about once a month at night after brushing my teeth and they are charged, ready to go the next morning. They are more expensive initially, but over time they are less than constantly buying new batteries.
I have been an Aldi shopper for 18 years. First in Malone, New York, and then in Toms River, New Jersey and now in Boynton Beach, Florida. When will Aldi’s have the Dentiguard power toothbrush again. I have looked all over, and cannot seem to purchase them.
Love my Dentiguard toothbrush. I had one for about 3 years before it crashed so bought another one. Make sure you keep it cleaned out under the detachable brush. Mine quit working at first after about a year because it was clogged up with hardened toothpaste sludge. Hey, for $5 it is a great brush. Beforehand I had an expensive toothbrush (about $70) that the replacement brushes were $9 ea. and it only lasted 5 years. My dentist is pleased with my oral hygiene.
My Dentiguard worked for 2 years. When it stopped (even after replacing the alkaline batteries) I took off the brush. Washed out some dried toothpaste, oiled the spindle, turned the body a couple of times using needle nose pliers. Now it again works well.
Hello –
I have a Aldi Dentiguard. I am looking for directions to swap brush head with new one.
I am looking through this feed because I too, am unable to swap the brush head. I read to twist the brush head counterclockwise while firmly holding the handle part. But my brush head will not budge.
Buy an “Equate” at Walmart. Functionally & mechanically identical.
2 soft toothbrush heads & the electric motor body for $5.
You get 2 new interchangeable brush heads & and a spare body.
brushes too hard batteries dont last a week vibrates hurts teeth do waste money
I have been using the Dentiguard Rechargeable Toothbrush since many years ago and am very satisfied with the performance and price of $19.99. Besides that they both look similar except for branding.
I got it to replace my previous Sonic Rechargeable gifted to me by my dentist and that was selling for $70.00 at the time but that conked out due to water leaking inside & rusting the motor.
My dentiguard is over 5 years old now & still working great with no signs of quitting any time soon.
I prefer my Dentiguard for the 5 modes that include “Deep Clean” mode which is the only mode I use.
I have not developed cavities ever and am complimented at each dentist visit for using an electric toothbrush.
The only drawback is knowing when it will appear on ALDI’S shelf.
So whenever I see it available I buy it for gifts to relatives.
I also order replacement brush heads from http://www.brushbuddies.com
They both worked great and suggest you give it a try instead oh spending on expensive battery replacements.
Thanks you to all that left messages and the original poster. The article and this feed was very helpful.
Here is a list of suggestions to help the Dentiguard last longer and work better:

I would like to know how to change batteries in the one I bought from Aldi. The base on the bottom looks like the place but it doesn’t want to move and I’m afraid I’m going to break it?
I have the dentiguard Power unit with batteries, bought from ALdi, works just fine. Where can I buy dual action/ double replacement brushes? Why does ALDi not sell them? Please let me know soon. Thanks
