Hi dot1 :
I have no advice about the allergy free products but wanted to add my child dealt with similar issues until he was older like yours. He had a big problem with solid introduction and we thought he had reflux, but looking back we see where it was actually an immature gut which lead to a leaky gut because we kept doing solids when he wasn't ready. We stopped with solids and started again when he was 10 months old. He was fine on breastmilk. The big foods causing issue in him were grains, next vegetables, then some specific fruit. Always good on eggs, and meat. He also ended up with Early Childhood Decay. We started solids on the recommendation of our pediatrician because it was supposed to help with reflux and it only made it worse.
Birch Xylitol is best. It's made in America. You can dilute with water and make a spray to spray her mouth after she nurses. Colloidal Silver is also good. No need for the high PPM either. 7 PPM should be just fine, the higher ones are like using a sledgehammer for a nail.
Have you also considered Pacalite Clay? Do you have dental issues too? The bacteria spreads from person to person. If it came in with a cavity, that is a concern. Makes me wonder about celiac disease or a vitamin deficiency. With things like reflux ( which can oftentimes me leaky gut ) there is a vitamin deficiency going on because the stomach problems mean improper digestion. Lastly, does your daughter have a lip or tongue tie? There's a holistic lactation specialist around here who's practically written the book about this issue, but she's linked lip/tongue tie, reflux, allergies, leaky gut all together. Pull up her lip and see if she has a membrane of skin that goes between or just above her two front teeth. Make sure her tongue has full movement. My son's almost 2 and we just found out about his ties 3 months ago.
Have grains ( wheat, corn, etc ) been absolutely ruled out yet? These are very difficult to digest for little ones and so are some veggies and fruits. Are you familiar with the Weston A Price Foundation? They've got good insight on this.
My son's first contact with food was rice cereal, it was organic brown rice cereal. We had vomit, screaming, arching back for days. Then we tried banana, sweet potato, and carrot later on. Same deal.
Have you considered a probiotic? Our son was on Zantac and it helped some, but a probiotic worked much better for him. When you introduce solids again, you may want to try some homemade stock and/or cooked egg yolk. Yolks aren't an allergen, but the whites can be as they have so many different proteins in them. Keep an eye out for frequent illness, like viral infections. This is also a sign of an intolerance or growing allergy. It's kind of like an auto-immune response to something the body can't digest. Sorry, I know your post is about dental issues, but I remember feeling at a loss when he was that young. Wish I knew then what I knew now. We learned the hard way to introduce solids very slowly in small amounts, at least a week apart. Also watch for things like runny nose, stuffiness, skin rash. The hardest part for me personally was eliminating things from my diet.
There's something called a posterior tongue tie. The tongue is tied near the back and it's very difficult to see. It looks nothing like the classic heart shaped tongue you'll find online. It's most often missed. The child needs to be laying down and you'll need to push on either side under the tongue to expose the frenum. My son just had his revised 12 days ago. There's a tongue tie support group on facebook with over 850 members and there's tons of information and photos and you can post photos there too. Lip Tie and Tongue Tie almost always come together. Yes, it can cause a poor latch and lots of additional air.
Since his revision his speech has improved, he's trying different foods, and he's been able to eat corn, oatmeal, rice, and cantaloupe without any issues. All these foods caused big problems before. I now firmly believe there's a big connection between tongue tie and gut health.
If you're concerned about a tongue or lip tie, you can find more information at www.kiddsteeth.com, under articles. Babies that have tongue and lip tie often have one, some, or all of the following issues : slow weight gain, breastfeeding issues, space between the two front teeth, high/narrow palate, digestion issues, colic/reflux as a baby and beyond, food issues ( intolerance,aversion, etc ), tooth decay.
I'm glad I helped ! You're on the right path.
