Tooth Decalcification: What are my options?

Hey there

I see this term popping up all over the place in other threads, but I can’t find a single decent explanation anywhere.

So, here’s the deal: my teeth are perfectly straight and white, but over the last year, I’ve had more fillings done than in my entire 24 years of life. Since I spend most of my day glued to my computer, I picked up this subconscious habit of chugging soda constantly. Even worse, lately, I’ve become totally addicted to swishing drinks around my mouth before actually swallowing—now I can barely take a sip of anything without swirling it first. 🙂
Naturally, the end result was tooth decalcification from my front teeth back to my premolars, which my dentist confirmed during a checkup the other day.

It feels like she’s totally brushing it off, though. Maybe it’s because she’s older and just counting down the days until retirement, who knows? Honestly, I’m freaking out about my teeth.

Has anyone else dealt with this? How did you fix it, if you even could? Also, if there are any pros in here who can weigh in, please help. The only advice I got from my dentist was "just drink water," so I've been on nothing but plain water for two days now.

If anyone can help, I’m all ears. Thanks!

Cut back on the soda and acidic drinks—or at least don't let them sit in your mouth for long. Also, skip brushing immediately after drinking them. Instead, pick up some GC Tooth Mousse and use it to coat your teeth...

You totally forgot to mention he can't touch citrus

It’s fine to eat, you just shouldn't overdo it, suck on things constantly, or let food sit in your mouth too long—the same rule applies to drinks.
