https://neurogal.com/neuro-blog/is-fluoride-toxic-to-the-bra... . HOW DO I AVOID FLUORIDE TOXICITY? 1. AVOID FLUORIDATED WATER 2. AVOID NON-STICK COOKWARE 3. CHOOSE YOUR TEA WISELY 4. USE FLUORIDE-FREE TOOTHPASTE I hate to be a contrarian, but the latest intelligence says fluoride is a neurotoxin.

I looked into one of the references...they put 120mg/L in mice and found it to be bad. Drinking water has about 0.7 mg/L. This is a factor of nearly 200x on concentration and another lot on body mass. Shoot, if I drink 200x more water that will cause problems too! Concentrations matter.

Appears as though my original comment was flagged. That's OK if the article wasn't well cited.

If you do a Fluoride search here on ycombinator you will find many article that point to fluoride as a nuerotoxin.

Cheers.

I can very much recommend an electric toothbrush against brushing too hard. Depending on the model it lets you know when you push too hard. It has helped me a lot. Also, according to my dentist the receded gums don't grow back which is quite scary.

Oh, but you can grow it back through a gun graft, and I had it done successfully. Healthy gum tissue is removed from the roof of the mouth and uses to build the gum back up where it has receded.

And it is an extremely invasive and painful procedure that should be avoided at all costs if you can. And if you don’t change your habits, you’ll have to have it multiple times.

I think we all use excessive amount of toothpaste. That makes us get a mouth full of foam, that subsequently forces us to rinse instead of just spit.

Great marketing by Colgate. They just show the toothpaste covering the entire length of the brush and we all follow along.

I just got a very short brush.
