Does anyone know if NOVAMIN based toothpastes (e.g. Sensodyne) have been tested?
- sct202 1y agoThe non-novamin Sensodyne was tested at 116ppb for lead and the tester listed the concerning ingredients: hydrated silica and titanium dioxide, which both are in the Sensodyne with Novamin tube I have from the UK.
- SV_BubbleTime 1y agoIt says Sensodybe right in the article. However, typical Guardian, it is an article telling you what to think and not giving you all the information. The question is, is there a safe level of lead, and are these tooth pastes under it?
- pogue 1y agoThey only tested US toothpastes
- more_corn 1y agoPretty sure the scientific consensus is there’s no safe level of lead exposure.
- SV_BubbleTime 1y agoThat is incorrect. The ideal amount is zero. But 1 part per 10 trillion is safe. So… we have an estimated upper limit. Could we lower it without being able to detect a change in health effects? Likely.
- pogue 1y agoNovamin toothpaste is only sold & mfg in the UK. There are some conspiracy theories going around that the ingredient is so good they won't sell it to us in the US! [1] I actually buy it off Amazon and use it myself because I have teeth sensitivity and it contains no SLS, which causes some irritation for me. It is quite interesting stuff. I doubt it would have lead since a synthetic compound.
