I noticed what looks like decay on the front teeth of my 22-month-old little girl. A brown spot, right between the two front teeth. We have been brushing her teeth for a long time now, and are especially diligent about it now that I noticed the spot. I don't know what exactly to do about it now. My older daughter (3 1/2) just had her first dental appt. The dentist (who I didn't like at all, but thats another issue) said just to keep an eye on my younger daughter's teeth for now and watch to see if it gets any worse. I'm so worried that she's going to have a lot of decay, and a lot early on. Is it worthwhile to have her teeth looked at now, before the decay gets worse? I wouldn't worry so much except that I had a ton of dental work done as a small child and it was absolutely miserable.
