My response would be to reevaluate soda and juices.

That would have a much more profound impact on your oral health. Probably your overall health too.

I just skip soda alltogether..or any sugary drinks 95% of the time

Edit: why i actually wanted to comment - my teeth stil suck

Genetics also play a lot when it's about dental health and longevity. Base-level dental health is negatively correlated to bone health for whatever reason, also if you have fragile nails you're more likely will experience bad teeth in your later life regardless of how much you brush, floss, etc.
