| Maybe the product is for dentists. It's a big lucrative market
| with products you literally can't buy over the counter.

| too).

|
| Do NOT try using eugenol for tooth sensitivity.

|
| There's some ways to build up enamel as long as you've not
| eaten away at the dentin (aka cavity). There's tooth paste
| and mouth wash that has small particles that get stuck in
| groves in your teeth and helps enamel grow. It also reduces
| sensitivity. My dentist recommended something for me so I'm
| assuming it's not one-size-fits-all.

|
| There are independent studies confirming the efficacy. The

|
| It's OTC in Europe but afaik on prescription in the US.
| Maybe buy it from an EU web shop, it's no more expensive

|
| I don't think that's a long-term solution for everyone, though.
| I have had painful sensations when drinking ice water or eating
| ice cream my whole life. My dentist sees no apparent reason for

| a cavity so I would imagine my enamel has been in good shape.
| If there's something else specific my dentist can look for to

| then it's new to me and my dentist.

|

|

| Yes, popsicles are pretty much a chore for me.
