Girls, hello! Who had teeth treated during pregnancy? They offered me free treatment for my teeth at my clinic. I have cavities, already a dentist examined them. Next week we'll start treatment. The doctor said that "anesthesia can't be injected, and in the last two lower teeth, deep cavities, I'll have to endure". I had cavities treated when I was 5 years old, like a drill drilling something there, I remember... so I have a fear left and since then I'm afraid of dentists. And now I don't know how painful it will be either. If you're scared and don't treat, the cavity will go even deeper. And they say it's free,
