RDA Testing for Toothpaste

measuring toothpaste abrasive value with RDA Relative Dentine Abrasivity

I’ve recently been on a quest to find a laboratory that does RDA tests for toothpaste to find the Relative Dentin Abrasivity of different brands of toothpaste. This was my second port of call after writing emails to companies asking for their RDAs, but discovering they have not conducting this test for their product.

Searching the web has shown me that information about how to find a lab that has an RDA testing service is not at all easy to find, which is why I wanted to share my findings here.

I used Google to search for scientific papers that involved measuring toothpaste RDAs, and then I wrote to the researchers to ask them if they could help me with finding where I could get this test done.

So far I have had two helpful responses from labs who perform this test. Here is the information I have been provided with:

  • Places that do the tests: Some universities and some clinical labs
  • Cost: It depends on the lab:
    - One clinical research lab gave an informal quote for £1,600 (approx $2,100)
    - One university lab gave a quote of upwards of £4,000 (GBP) or $5,300 (USD) per toothpaste test.
    Because of the high cost, often legal contracts are required to be signed in order to do the test.
  • Timeframe:
    The timeframe of testing is lengthy:
    - Contracts need to be signed months before tests can be run;
    - Many labs run tests at a particular time of year, so only do tests in, say, September-to-December, so if you want a test done in May, you would have to wait to the next run of tests the following September.
    - Sending and preparing the samples for testing can also take a few months;
    - And then the results of the test will only be available several months after testing too.In all, between asking for the test and getting the results it can take many months and up to a year.

In case you’re curious, this is what the toothbrushing machine used for RDA tests looks like (seen from about 20 seconds into the video):

I will update you if I discover any labs that offer this service in a more layman-accessible way for citizens like me who are interested in dental health and want to confirm the abrasiveness abrasive level of their toothpastes for healthy, happy teeth. In the meantime, I would suggest: it is definitely easier to email the toothpaste company and ask for their RDA values rather than get the testing done yourself, and if the company does not have an RDA value, using a different brand that can provide you with this information would definitely be the easiest path to take.


Toothpaste RDA Testing lab test for dental healthJust to put it out there, brands who haven’t had their RDAs tested and who I’d really like to know their RDAs are:

  • YoungLiving toothpastes including Thieves AromaBright, Thieves Whitening & KidScents
  • Miessence toothpastes: Email correspondence said all their toothpastes have an RDA of “7″, but this seems too low to me especially considering their toothpastes have a whitening effect and are grainy in texture.
  • Kingfisher toothpastes: This British company has great ingredients in their tooth paste but since the UK does not require RDA testing they have not had it done.

If you have any information on the RDAs of the above brands, or any information on where you can get a toothpaste’s RDA measured at a more affordable price in a shorter timeframe, please do leave a comment below to let me know.

When you feel insulted when someone insults your hobby or interests…

Why we take it personally when someone doesn’t like something WE like and what we can do to not take it personally in the future


“It’s not stupid, YOU are!”
This is a classic schoolyard retort to someone insulting a “thing” you like, and this retort shows that people can get offended when you offend something they care about. They can take it so personally, that accordingly their retort is a personal insult too.

But why do we sometimes take it personally and other times we don’t care?
When we take it personally it’s because in our minds We fill in the gaps and identify who we are personally with the “thing” we like. We fail to see the separate distinction between “who we are”, and “the thing” in question. We think:
If they’re saying the thing I like is stupid, they are saying *I* am stupid for liking it.
If they say the thing I like is boring, they are saying *I* must be boring or stupid for liking a boring thing.

But sometimes someone just finds something boring, and they don’t think any less about you for liking that thing.

Like, one person may find biomedical science boring to learn about themselves, but you can still be a genius scientific researcher who find that stuff very interesting and they can admire you for liking the very thing that they find boring. If THEY find it boring, it does not necessarily reflect negatively on you that you are interested in it. If you have it in your head that it’s a personal insult that they find it boring, it is more revealing about how YOU feel about this “thing” – are you proud of liking this thing?

If you’re proud of your interest in biomedical science, and are secure in knowing that it’s a good thing to learn about it, and it’s a field that can be helpful to the world- then no matter whether someone else finds it boring or not, it probably won’t matter to you, because YOU are secure in knowing it’s of value, no matter how anyone else feels about it.

But, if you’re not proud or secure in your interest, it’s a different story.
For example:
If the thing that’s insulted is your boyfriend, husband, friend, or your job, or a hobby you spend a lot of time on…
Say, if you have a hobby like watching a certain youtuber and you are an ardent fan who’s spent hundreds of hours watching their videos, following them on social media etc, but part of you thinks:
“There may be better ways to spend my time than watching these entertaining videos all day… I mean, it’s entertaining and fun, but I dont think I’m adding anything positive to the world by watching these.. I could be using my time more wisely in a way that has more value to myself and to the world…”,
THEN when someone tells you your interests (in this case your interest in your beloved youtuber and their videos) are boring, it resonates with your own self-judgement and your own uncertainty about this hobby, and so it feels more like an insult and hurts your feelings. But it only feels like an insult because of your own insecurity.

So what can we do about it when someone insults a THING we like, and we get offended personally by it?

1.) In the moment, if you feel hurt, recognise that there is a belief or thought within youself that maybe is insecure about the “thing” in question. Are you proud of this interest you have? This is an opportunity for self-reflection. The judgemental person can be a catalyst to helping you realise something important about yourself and about how you spend your time.

2.) If you know you’re insecure about the “thing” in question – you can work on improving how you feel.

You can either:

(a.) Pivot your thoughts to show yourself why the thing you like is a good thing to like. Build up your own feelings of security and certainty and sureness about it so that you get to a mental head-space of believing that it IS absolutely the right thing for you. List all the good you get out of it – show yourself why it IS valuable, why it IS a good use of your time. And practice these kinds of thoughts until you feel more secure about it. Sometimes it can take some practice to nurture this positive-feeling belief and can take repeated self-reminders over some time (especially if you’ve been getting a feeling of doubt and uncertainty about it building momentum for a long while). Nurturing a new belief & sense of security in something is often not an instant thing so be patient with yourself as you build your sense of security.

For example, in the case of someone who spends a lot of time watching a youtuber: if their videos bring you joy, that’s a good use of your time, because being happy and feeling good is super valuable! And sometimes you learn about new interesting stuff from their videos, or get inspiration maybe to do fun things – that’s valuable too.

(b.) Let this be a chance to re-examine: maybe this “thing” really isn’t the best for you? Is there something else you’d rather be doing with yoru time? What’s stopping you from doing that other thing that you want to do?

Rampage of Appreciation for Sport

When you use your body physically in sport, there are so many good things you can gain from sports:

You feel the aliveness in your body as the fresh air rushes through your body and fills your body with aliveness!

For many sports you get to interact with the fresh air – to be outside, maybe appreciating the feeling of the grass beneath your feet, or the feeling of the sunshine shining down on you, lighting up the world around you with its golden beams.

How great it feels to USE your body!

How great it feels to acomplish results with your physical body and with your physical strength!

How much appreciation it gives you for your body and strength!

You learn to go beyond what you thought your limits were.
You see yourself improving and getting better with practice which is so satisfying!

You learn that practice, and patience to allow yourself the time and space to get better and better – gets results.

You learn what it feels like to use your body in a way which feels like you’re using all your muscles to the max; using your body to the max – utilising your full potenetial – which is a wonderful feeling to know that you’re using your talent and potential to the fullest that you can!

You learn to look after your body and respect it so that it will help you to function optimally – to achieve that satisfying fullest potential.

You learn teamwork; because for many sports in order to win, you need the team to win.

You learn the satisfaction of how great it feels when you are able to succeed even when conditions are challenging.

You learn to keep going and not to give up.

And sport can even be a kind of meditation. When you play, you’re not thinking about taxes and politics – no! you’re focused! you’re focused on the sport! And for that time that your focus is on the sport, your thoughts are free of the normal baggage – and you are lighter; freer.. no wonder engaging in sport feels good!

What Feelings are made of according to Abraham Hicks

I just read a great quote by Abraham here about “the composition of feelings” and what are feelings made of when you break them down and examine their smaller components. The gist of it was as follows:

Most feelings are made up of 2 factors:
1.) Desire
2.) Resistance to that desire

For example:
- Passion = Strong desire + No Resistance
- Contentment / Peacefulness = Not much desire + No Resistance
- Boredom = not much desire + a little resistance
- Frustration / Anger / Guilt / Depression = Strong Desire + Strong Resistance
- Clarity = desire (to know) + no resistance

Isn’t that interesting and fun to know? ^_^

What is Nervousness according to Abraham Hicks

What is Nervousness?

Nevousness is a manifestation and an emotional indicator.

When you’re in the place of nervousness, it is an emotional indicator that vibrationally you are not expectant of the thing you want.

Nervousness is when there is doubt as to whether the thing you want will come or not. There isn’t certainty that the good thing is coming.

Nervousness is an active vibration that is to the contrary of what is wanted ie it means you have activated some focus of “what you do not want” along with “what you do want”. You have split focus. The ratio of focus may differ but if you’re mostly feeling nervousness, perhaps the ratio is skewed in the direction of “doubt and fear that it’s not coming” than in that “it’s coming”.

Nervousness means you are not entirely ready for what you want.

- – -

How do you come to be in a place of nervousness?

It is when you observe in your life experience that things don’t go your way, and then form a belief that “things don’t always go my way”.

This old beliefs could have been formed yesterday, last year, in your childhood etc… but that you are keeping active now.

How to overcome habits of nervousness

If you’ve trained yourself into reacting nervously to situations, and it’s become a habit, how do you get out of this habit?

By deliberately practising new vibrational patterns and then watching the outcome of it until you show yourself that you have vibrational control.

Think about what you want more.
Appreciate the idea of what you want more – allow yourself to feel good about it.
Imagine what you want; what it would look like; what it would feel like. Prepave it.
Prepare yourself for what you want (eg if you want to be called to the Abraham Hot Seat, prepare yourself by dressing for the part etc coz you know if you’re picked people will see you more in the spotlight).
The more you pre-pave what you want, the less hindering the old negative beliefs will be.
