My oldest got his first molars around 1 yo. He started getting teeth at 6 months! Then he got his second set of molars (the very back ones) just before he turned two. With him cutting teeth never really bothered him. He just drooled a lot constantly...still does at 3.5 years old. But I think his "2 yo Molars" as they are called, gave him a slight fever and that's it.
I wouldn't worry. It probably looks like that because your daughter is chewing on the already swollen gums to get relief from the pain. In a few days it should look better.
Just keep an eye for signs of infection....fever over 100 degrees, pulling on ears (sign of ear infection), lethargy, etc.
If they bother her, try Hyland's natural teething tablets. They are really helping my 17 month old, she is cutting 4 top teeth all at once right now :(!
