Pam:
I use Crest reg paste once a day, as that's all my stomach can handle then use Walgeen's mouth wash without alcohol, the other couple times a day. A little messy but haven't had any teeth issues since I started this. Orginally tried Crest 3 times a day but my stomach just couldn't take it & with my skin sensitivity, it also made my mouth burn too much. One thing I don't do is get the flouride treatment from the
dentist. After masto, the first time I went outside & threw up from it.
They also use the non-flavored paste to clean my teeth, then I've had no problems at dentist. I've got a very nice dentist & staff who although I'm weird don't make a big deal of my issues.

There are many homemade toothpaste recipes on the internet.  (Google:  homemade toothpaste)  You can flavor them with any oil flavoring you like and can tolerate.

My brother in law is a dentist and said you can use baking soda as a rinse mixed with water to deodorize. You can also use peroxide. If you can't tolerate tooth paste you just need to brush longer 5 min. with a wet tooth brush. Have you used a tongue scraper? They work really well for removing bacteria.

Having refined my diet and managed to bring my symptoms down it  has become clear toothpaste is a massive trigger for me.

the chemical products and even the natural ones. It is almost definitely the calcium in them. I can't even brush my teeth ffs.

I tried bicarb on it's own, but even that isn't too great.

Any suggestions?

Nick, what symptoms do you get after using toothpaste? It sounds as if there are a few alternatives that are posted in this thread. You should give them a try.

For anyone with toothpaste issues: although you are for obvious reasons focused on your mast cell symptoms, you must not forget the importance of taking care of your body in regard to non mast cell issues. Our teeth are very important and it is imperative to take care of them. If your symptoms are mild from brushing, perhaps you need to increase your meds so that you can still take care of your teeth and use toothpaste. Also, be absolutely sure that it is the toothpaste and not something else that is bothering you. Mast cells are very tricky and certainly not like allergies in that an ingredient can bother you one day, but not the next. Now, if you are a shocker, you need to be more careful. So, for example, if shellfish were in toothpaste and I know that I go into anaphylaxis from shellfish all the time, then obviously I wouldn't use the toothpaste and would just keep googling alternatives until I found something that worked. If apples were in the toothpaste, and I generally mildly trigger from apples but don't shock from them, then I would use the toothpaste and be careful not to swallow any of it. Now, obviously my examples are ridiculous, but that is to get my point across. Although I am a shocker, I will still eat something that I know affects me mildly because I know that it won't be a big deal and the symptom will fade soon enough (or I could take an extra med if it didn't). So, if it were me, I would keep experimenting and trying toothpastes. (Now I will admit that I am obsessed with teeth brushing and brush my teeth multiple times during the day. Happily, I have terrific teeth and even at my age have only had 3 cavities ever. I know that is a result of the tooth brushing.)

Another thing to remember is that if you expect yourself to trigger from trying a toothpaste, you can think yourself into triggering. So, be careful with your assumptions to get a true evaluation. Just as we can talk our symptoms into calming down, we can talk them into acting up as well.

I found another toothpaste that does not contain calcium or bicarb. But I actually think the effects of toothpaste were being exacerbated by something else....

I use a neilmed sinus rinse kit which clears up my brain fog a bit and helps me to think more clearly. However, I fear I pay the long-term price....

Since not taking the sinus rinse for a few days, my symptoms are calming down. Phew - I can brush my teeth  

Hello Pam! I don't know what exactly was in my toothpaste but the skin on the entire inside of my lips and cheeks would peel after brushing my teeth. I finally switched my toothpaste a couple months ago to Tom's of Maine. No more skin peeling:)  I buy it from Kroger. Here is the list of ingrediants on it:

glycerin, water, calcium carbonate, hydrated silica, xylitol, Chondrus crispus (carrageenan), Gaultheria procumbens (wintergreen), leaf oil and other natural flavors, sodium lauryl sulfate, sodium bicarbonate, zinc citrate.
