Does this look like a tooth?

Faith

My LO is only 6 and a half months. He already has his 2 bottom teeth that came in just a month ago. Could he already be getting a top tooth on the left in this pic? He’s been acting off , not sleeping well, not taking as much milk and just seems upset. I didn’t think babies got their top teeth until closer to 9 months . 🤷🏻‍♀️
