Dr Lewis Ehrlich is a highly sought after holistic dentist who graduated from James Cook University (JCU) with the Academic Medal. With a background in professional sport and his passion for holistic health, Lewis focuses on the link between oral health and general overall health in his practice - it’s why you’ll never hear a bandaid solution for an oral health concern in my interviews with him! 
Before studying dentistry, he completed a Bachelor of Science at Northeastern University in Boston, USA after receiving a soccer scholarship where he played for 2 years. He then moved to Reykjavik, Iceland where he played professional soccer before moving into dentistry and now practicing at Sydney Holistic Dental.  
This show, part 1 of two that I’m recording with Dr Lewis, is the result of my asking the Low tox club chat group and alumni course groups if they had any ongoing concerns and questions about oral health - from teeth (grinding / enamel / cavities) to gums to oral microbiome to jaws to treatments and appliances and preventative health. There I was thinking I was going to be doing a show on grinding and appliance options with ‘a few’ questions from you guys but when 100+ questions quickly presented themselves, I changed tack and turned it into a two part “All your holistic dentistry questions” answered. So in this show, part 1, we talk about tooth enamel - when it’s weakened / why / what to do as well as various apparatuses you might be thinking about using be it metal wires, myo brace, invisalign, silicon and plastic plates and spacers etc. The show notes have a tonne of resources with toothpaste recommendations that both do and don’t contain fluoride, as well as floss recommendations, useful extra-listening podcasts and Dr Lewis’s practice details, as well as our show supporter offer. Head over to lowtoxlife.com/podcast for all the details. 
Here are the questions answered in this first FAQ with Lewis and we twist and tangent on all things oral care in between:  
On the enamel... 
My daughter has crap enamel. Tips to improve? She was recommended tooth mousse but has casein ( to which she is allergic). We do do cod liver oil ( Nordic naturals). We were also recommended the clear protective coating that lasts a few years, I believe it’s made of plastic though! Would love to know more about that also.
Why do we see such an influx of kids with hypoplasia (enamel not formed properly) and what are the REAL causes?! I just can’t quite believe that it is something that happened in utero because the mother was ill or antibiotics may have played a part (neither applied to me and yet one of my kids has a severe case of hypoplasia). I know sooooo many kids with this problem, is there any new research that can pin point the cause of this yet? Maybe environmental causes (wouldn’t it be crazy if we all found out it was an everyday toxin that caused this in this generation of kids). This is a really heartbreaking story for us, my son is only 7 and so conscious of his teeth and we are constantly at the specialist dentists, feeding him the best food possible etc. 
I also really want to know about hypoplasia! Is there anything we can do to improve it and strengthen the teeth? Is there some kind if plan we can follow to avoid lots of decay in the future? My daughter had perfect baby teeth and her new teeth have all started coming out blotchy and with discoloured patches. Poor thing is so self conscious already. Thanks for giving us the chance to ask. 
wanting to know about crap enamel and fluoride - is tooth mousse and fluoride in water REALLY necessary?
We went and saw Lewis Ehrlich for my son and he recommended tooth mousse to help improve his enamel but then our current paediatric dentist (not a holistic one) said he doesn’t believe the product is necessary and strongly advised to use fluoride to help strengthen the enamel. I would like to know the best option to help strengthen enamel low tox or not.
