Before You Buy Another Gum Toothpaste or Water Flosser, Read This

A brush, floss, a water flosser, a rinse, a special toothpaste. Every one of them does the same kind of job. A look at the job none of them does.

By the Health Desk

Open the cabinet of anyone who has fought bleeding gums for a while and you'll find a small collection. A spare toothbrush, maybe an electric one. Floss, floss picks, possibly a water flosser. A mouthwash. A toothpaste that promises something about gums.

One person on a forum listed what they had been through: three water picks, special toothpaste for sensitive teeth and gums, and every kind of brush they could find. Their mouth still bled.

Here is what's interesting about that collection. Every item in it does the same kind of job. It cleans. It takes something away from your teeth and gums.

That job matters, and nobody should stop doing it. But if you have done it well for years and still bleed, it may be worth asking a different question: what about the part of oral care that doesn't involve removing anything?

So here is the short version, before anything else goes in your cart. If you already brush and floss every day, another cleaning product may just give you more of the same job. Get your technique checked first, because that doesn't require buying anything. And if you still bleed after that, look at the one kind of step your cabinet doesn't have.

The rest of this article explains why.

Who this is for

This isn't for someone who skips flossing. It's for the people who don't.

You'll find them in forum threads about bleeding gums. Here is one, posting a question to a dental forum on Reddit:

"I brush and floss religiously and my gums still bleed when I floss. Especially any place I've had previous work/fillings. I don't know what I'm doing wrong. Even my hygienist just told me she can tell I take good care of my teeth."

Here is another, after half a year of doing exactly what they were told:

"Six months of flossing twice a day, yep gums still bleed."

And on Ask MetaFilter, a question-and-answer site, in a 2025 thread about whether other people's gums bleed at the dentist, one person with a careful routine wrote:

"my gums bleed despite brushing 2x daily and flossing 1x daily. My dentist just shrugs and goes on with the cleaning."

To be fair to that thread, many of the answers said flossing more often had helped them. But several came from people who were already doing it. One described brushing three to four times a day, flossing two to three times a day, using a special gum toothpaste and getting cleanings twice a year:

"My gums don't bleed or hurt when I floss at home, but they sure do at the cleaning."

If that is you, you are not imagining it, and you are not alone. Even people with a very good routine can still bleed.

Why people keep buying

There is a reason the cabinet fills up. For some careful brushers, the bleeding comes with a conversation they are tired of having.

One person asked, in a thread about exactly this:

"I'm wondering why, even when I floss after every meal and brush twice a day, the dentist says I'm not because my gums are bleeding when she's poking them with that god forsaken probe."

Another remembered it from childhood:

"It was so frustrating as a kid to have the dentist always telling me I don't brush and floss when I knew I did and then my parents would yell at me."

When the advice you hear is to clean more, and you already clean a lot, the natural response is to clean harder or clean with something new. So people buy. A softer brush. An electric one. A water flosser. A toothpaste with "gums" on the label.

What some of those cabinets look like

Here is how some of those people describe what they have tried.

The person with three water picks put it bluntly:

"Use a water pick! Have been through 3, use regular floss in the morning and the water pick at night, still gush out blood."

They had also tried toothpaste for sensitive teeth and gums, and every kind of brush they could find: manual, electric, and one shaped like a mouth guard.

Someone else did everything gently, the way you are supposed to:

"I use a soft bristled electric toothbrush on soft setting and am gentle but still, blood blood blood."

And one person turned it into a year-long experiment:

"I brushed, flossed and used scope, for an entire year as a challenge, my gums still bled at the dentist."

None of those products is the problem. A good brush, floss, a water flosser and a sensible toothpaste all do real work, and you should keep using them. The point is narrower than that. Every one of them does the same kind of work. Buying one more of them is buying one more way to remove.

Check this before you buy anything

Here is the warning that matters most, and it doesn't involve buying anything. Before you spend money on another product, make sure the tools you already own are being used well.

In the same threads, many people describe bleeding that eased once their cleaning changed. One wrote:

"After I formed the habit and brushed and flossed every day for a little while the bleeding stopped. It also helped that I had a dental hygienist show me how to properly floss. Technique is apparently really important so if someone is flossing but still bleeding it's possible their technique needs looked at."

Another flossed in front of the dentist after years of being told to floss more, and found the gap:

"Im 23 and just found out i never learned how to floss "properly" had no clue you had to dig up in the gums."

A MetaFilter commenter who flosses twice a day, and gets compliments on their home care, still bleeds in two spots and knows why:

"I just don't reach them as well when I'm flossing even as regularly as I do."

And someone who said they work as a lab tech at a dental office offered this on Reddit:

"A lot of times stubborn gum bleeding with normal brushing comes from tartar/calculus buildup under your gums."

So, before anything new goes in the cart:

• Ask your hygienist to watch you floss and brush. It can feel awkward. It is also one of the most useful things anyone in these threads reported doing.
• Ask about buildup under the gumline. The same person said hygienists scrape that buildup off during a cleaning.
• See your dentist about bleeding that continues. Bleeding gums can signal something only a dentist can assess, and that is worth ruling out.

Some people do all of that and still see pink when they rinse. If that is you, the next question is the one to ask about anything you buy.

The question to ask about your next purchase

Does it remove, or does it add?

Go back to the cabinet. Brush, floss, water flosser, mouthwash, special toothpaste. Every one of them works by removing: food, plaque, buildup. That job is essential.

But everything in that cabinet takes something away. Nothing in it adds anything.

Here is one way to look at it. Your routine is the part of oral care that removes. A probiotic is a different kind of step: it adds bacterial strains to the mouth. The two don't compete. One doesn't replace the other. They are simply different jobs.

That idea doesn't mean your routine has been failing you, and it isn't a promise about your gums. It is simply a way of seeing why one more cleaning product can feel like going in circles. If you have already done the removing part as well as you can, the adding part is the side of the picture you may never have tried.

If you decide to add something, check these five things

If you do look at an oral probiotic, here is what we'd check, using one product as the example: ProDentim, a chewable probiotic tablet made for the mouth.

1. What is actually in it? ProDentim's label lists three probiotics: Lactobacillus paracasei, B. lactis BL-04 and Lactobacillus reuteri, along with inulin, malic acid, tricalcium phosphate and peppermint.

2. Does it fit next to your routine, or ask you to change it? You chew one tablet slowly each morning. It doesn't ask you to brush longer, floss differently or buy another gadget.

3. Is it a subscription? We found no subscription, autoship or repeat billing on the ProDentim sales page. It is a one-time purchase.

4. What happens if it isn't for you? ProDentim comes with a 60-day money-back guarantee. In the maker's words, if you aren't fully satisfied you "can just return what you haven't used for a full, no question asked refund."

5. Does it claim to replace your dentist or your floss? It shouldn't, and you shouldn't treat it that way. Keep brushing, keep flossing, keep your check-ups. If you take medication or have a medical condition, the maker advises showing a bottle to your doctor before you start, and so do we.

Common questions

Should I throw out the water flosser or the gum toothpaste? No. They do real cleaning work. The point of this article is only that they all do the same kind of work.

Should I stop flossing if it makes my gums bleed? No. Several people in these threads found that bleeding eased once flossing became consistent and their technique improved. If it keeps bleeding, that is a question for your dentist.

Will a probiotic stop my gums from bleeding? Nobody can honestly promise that, and we won't. What it does is a different job from cleaning. The 60-day refund on what you haven't used is there so you can judge it for yourself.

Which pack would you look at? At one tablet a day, the six-bottle pack is listed as a 180-day supply, and the page lists free US shipping on the larger packs. For a daily habit, that is the one we'd look at first.

The bottom line

Before you buy another gum toothpaste or water flosser, ask what it adds that you don't already have. If the answer is "more cleaning", and you already clean well, get your technique checked instead.

Keep your routine. Add the step it can't do. See the current ProDentim offer and the 60-day refund terms.
