Update: This post was originally published in 2016. Now it’s 2021, and in the interest of providing helpful information, I want to share what I’m doing now to reduce sensitivity.

I brush with a toothpaste from the company Boka that contains nano-hydroxyapatite, “a fortifying, 100% non-toxic version of hydroxyapatite, a mineral that makes up the primary foundation of teeth and bones.” It remineralizes teeth, reduces plaque, and reduces sensitivity.

I got a two-pack, a mint-cardamom-green tea flavor as well as their coconut-ginger flavor with chamomile, so I could try each flavor. So far, the coconut-ginger is the more refreshing flavor. If you want to try it, here’s my affiliate link.

My tooth sensitivity has diminished quite a bit, and cold water no longer makes me cringe!

Read on to learn about my path to get here.

I wanted to remineralize my tooth enamel after drinking water with lemon and noticing my teeth had become so sensitive it was scary. Drinking it first thing in the morning had softened my enamel, and by brushing my teeth right after drinking it, I was literally brushing my protective enamel away. Yikes.

My previous post from a couple of years ago contains many suggestions on how to drink water with lemon safely, preventing a loss of enamel.

After writing that post, I started researching how I could rebuild my tooth enamel. Now this is not something most dentists will tell you is even possible.

There is no hard scientific evidence about how to do this (so far, except for some data on fasting, which spurs the body to generate stem cells that repair tissues). Fortunately, one dentist did extensive research. More on him below.
