I hate these sores with a passion. You can fix them instantly with Oralmedic from the internet (possibly currently undergoing supply chain issues but that is temporary). It is agonizing— you are cauterizing the sore— but provides immediate and permanent relief. You can also get a laser for it, which does not hurt but is way higher effort and costs a ton more. I am passionate about my sore hatred so I have done this.
If you don’t want to do either, Canker Shield is available on Amazon and reduces sore lifespan to around 24-48hr. Also painful to use but nothing is as bad as Oralmedic or debacterol. Combine that with supplements (not one size fits all, lysine seems to have high success rate though) and you can deal with these while away from home.
Anyway this tip actually reminded me to check my travel toothpastes which naturally do have SLS. So thank you. I had noticed an uptick to a sore every couple months since Covid “ended” but that cause slipped my mind
I used to leave aspirin on the canker, that burned it away.
That lazer sounds really cool. What one did you get?
I had one custom made to avoid the cost of medical grade/dental lasers. You can make your own pretty easily with a diode and some other parts but I wanted a good shape for reaching the affected areas and my metalwork skills are nonexistent. I had it specced at 810nm, 600mW.
Be sure not to do this without knowledge of high powered lasers! At that wavelength and wattage it’s pretty weak for lasers, but still >100x the wattage of a typical laser pointer. It won’t burn through things like other similar lasers, but it will blind you with no warning and no room for error if you’re not careful and using the right glasses. Lasers are not actually very fun at all since you have to be very cautious.
Ahh so it is a DIY lazer. I was thinking it was a commercial product you would buy.
There are commercial medical/dental lasers but they’re decently more expensive. Still worth it but as a laser hobbyist I’m comfortable with the things. You can find them by searching for an 808nm dental laser.
Oh, they’re kind of big, which is the other downside. Make sure to still use the appropriate glasses
There’s also a device that uses red light instead, I think called luminance red. Not as effective but way cheaper than everything but a DIY with your own diode, and still reduces sore length for most people
