Can a first kiss be a decisive factor in determining whether a flirtatious connection progresses or fades away?

Well I have been seeing a very nice girl for a while. Recently, after we had a nice dinner, I dropped her off at her house and I wanted to end the night with a nice kiss, but she ended the kiss suddenly and told me that I tasted blood in my mouth. I had completely forgotten that I had my tooth extracted the day before and didn't realize that it was bleeding. Do you think this failed first kiss could mean the end of a relationship that never started? We talked a few times after that day but I couldn't really understand what she was thinking.
