Toothpastes and mouthwashes: which kinds help, and which kinds harm?

You almost certainly brush your teeth. You might use mouthwash. A lot of people floss for three weeks at a time, often in January.

There are a lot of options for oral hygiene; variations of the above, and many alternatives too. This is a big topic, so rather than try to squeeze it all in one, this will be a several-part series.

For today, let’s look at toothpastes and mouthwashes, to start!

Toothpaste options

Toothpastes may contain one, some, or all of the following, so here are some notes on those:

Fluoride

Most toothpastes contain fluoride; this is generally recognized as safe though is not without its controversies. The fluoride content is the reason it’s recommended not to swallow toothpaste, though.

The fluoride in toothpaste can cause some small problems if overused; if you see unusually white patches on your teeth (your teeth are supposed to be ivory-colored, not truly white), that is probably a case of localized overcalcification because of the fluoride, and yes, you can have too much of a good thing.

Overall, the benefits are considered to far outweigh the risks, though.

Baking soda

Whether by itself or as part of a toothpaste, baking soda is a safe and effective choice, not just for cosmetic purposes, but for boosting genuine oral hygiene too:

• Enhanced plaque removal to improve gingival health: 3-month randomized clinical study of the effects of baking soda toothpaste on plaque and gingivitis
• The effects of two baking-soda toothpastes in enhancing mechanical plaque removal and improving gingival health: A 6-month randomized clinical study
• The efficacy of baking soda dentifrice in controlling plaque and gingivitis: A systematic review

Activated charcoal

Activated charcoal is great at removing many chemicals from things it touches. That includes the kind you might see on your teeth in the form of stains.

A topical aside on safety: activated charcoal is a common ingredient in a lot of black-colored Halloween-themed foods and drinks around this time of year. Beware, if you ingest these, there’s a good chance of it also cleaning out any meds you are taking. Ask your pharmacist about your own personal meds, but meds that (ingested) activated charcoal will usually remove include:

• Oral HRT / contraceptives
• Antidepressants (many kinds)
• Heart medications (at least several major kinds)

Toothpaste, assuming you are spitting-not-swallowing, won’t remove your medications though. Nor, in case you were worrying, will it strip tooth enamel, even if you have extant tooth enamel erosion:

However, it’s of no special extra help when it comes to oral hygiene itself, just removing stains.

So, if you’d like to use it for cosmetic reasons, go right ahead. If not, no need.

Hydrogen peroxide

This is generally not a good idea, speaking for the health. For whitening, yes, it works. But for health, not so much:

Hydrogen peroxide-based products alter inflammatory and tissue damage-related proteins in the gingival crevicular fluid of healthy volunteers: a randomized trial

To be clear, when they say “alter”, they mean “in a bad way”. It increases inflammation and tissue damage.

If buying commercially-available whitening toothpaste made with hydrogen peroxide, the academic answer is that it’s a lottery, because brands’ proprietorial compounding processes vary widely and constantly with little oversight and even less transparency:

Mouthwash options

In the case of fluoride and hydrogen peroxide, the same advice (for and against) goes as per toothpaste.

Alcohol

There has been some concern about the potential carcinogenic effect of alcohol-based mouthwashes. According to the best current science, this one’s not an easy yes-or-no, but rather:

• If there are no other cancer risk factors, it does not seem to increase cancer risk
• If there are other cancer risk factors, it does make the risk worse

Non-Alcohol

Non-alcoholic mouthwashes are not without their concerns either. In this case, the potential problem is changing the oral microbiome (we are supposed to have one!), and specifically, that the spread of what it kills and what it doesn’t may result in an imbalance that causes a lowering of the pH of the mouth.

Put differently: it makes your saliva more acidic.

Needless to say, that can cause its own problems for teeth. The research on this is still emerging, with regard to whether the benefits outweigh the problems, but the fact that it has this effect seems to be a consensus. Here’s an example paper; there are others:

Flossing, scraping, and alternatives

These are important (and varied, and interesting) enough to merit their own main feature, rather than squeezing them in at the end.

So, watch this space for a main feature on these soon!

Realistic chronic pain management

We’ve had a number of requests to do a main feature on managing chronic pain, so here it is!

A quick (but important) note before we begin:

Obviously, not all chronic pain is created equal. Furthermore, we know that you, dear reader with chronic pain, have been managing yours for however long you have, learning as you go. You also doubtlessly know your individual condition inside out.

We also know that people with chronic health conditions in general are constantly beset by well-meaning unsolicited advice from friends and family, asking if you’ve heard about [thing you heard about 20 years ago] that will surely change your life and cure you overnight.

It’s frustrating, and we’re going to try to avoid doing that here, while still offering the advice that was asked for. We ask you, therefore, to kindly overlook whatever you already knew, and if you already knew it all, well, we salute you and will not be surprised if that’s the case for at least some readers. Chronic pain’s a… Well, it’s a chronic pain.

All that said, let’s dive in…

How are you treating your body right now?

Are you hydrated; have you eaten; are you standing/sitting/lying in a position that at least should be comfortable for you in principle?

The first two things affect pain perception; the latter can throw a spanner in the works if something’s not quite right.

Move your body (gently!)

You know your abilities, so think about the range of motion that you have, especially in the parts of your body that hurt (if that’s “everywhere”, then, our sympathies, and we hope you find the same advice applies). Think about your specific muscles and joints as applicable, and what the range of motion is “supposed” to be for each. Exercise your range of motion as best you can (gently!) to the point of its limit(s) and/or pain.

• If you take it past that limit, there is a good chance you will make it worse. You don’t want that.
• If you don’t take it to the limit, there is a good chance your range of movement will deteriorate, and your “safe zone” (i.e., body positions that are relatively free from pain) will diminish. You definitely don’t want that, either.

Again, moderation is key. Yes, annoying as the suggestion may be, such things as yoga etc can help, if done carefully and gently. You know your limits; work with those, get rest between, and do what you can.

For most people this will at least help keep the pain from getting worse.

Hot & Cold

Both of these things could ease your pain… Or make it worse. There is an element of “try it and see”, but here’s a good general guide:

Here’s How to Choose Between Using Ice or Heat for Pain

Meditation… Or Distraction

Meditating really does help a lot of people. In the case of pain, it can be counterintuitively helpful to focus for a while on the sensation of the pain… But in a calm, detached fashion. Without judgement.

“Yes, I am experiencing pain. Yes, it feels like I’m being stabbed with hot knives. Yes, this is tortuous; wow, I feel miserable. This truly sucks.”

…it doesn’t sound like a good experience, does it? And it’s not, but paying it attention this way can paradoxically help ease things. Pain is, after all, a messenger. And in the case of chronic pain, it’s in some ways a broken messenger, but what a messenger most needs is to be heard.

The above approach a) is good b) may have a limit in how long you can sustain it at a time, though. So…

The opposite is a can be a good (again, short-term) approach too. Call a friend, watch your favorite movie, play a video game if that’s your thing. It won’t cure anything, but it can give you a little respite.

Massage

Unless you already know this makes your pain worse, this is a good thing to try. It doesn’t have to be a fancy spa; if the nature of your pain and condition permits, you can do self-massage. If you have a partner or close friend who can commit to helping, it can be very worth them learning to give a good massage. There are often local courses available, and failing that, there is also YouTube.

Here’s an example of a good video for myofascial release massage, which can ease a lot of common kinds of chronic pain:

Some quick final things to remember:

• If you find something helps, then it helps, do that.
• That goes for mobility aids and other disability aids too, even if it was designed for a different disability. If it helps, it helps. You’re not stealing anyone’s thunder (or resources) by using something that makes your life easier. We’re not in this life to suffer!
• There is no such thing as “this pain is not too much”. The correct amount of pain is zero. Maybe your body won’t let you reach zero, but more than that is “too much” already.
• You don’t have to be suffering off the scale to deserve relief from pain
