Refusing to eat

My daughter was ill a few weeks ago and off her food (understandable and normal), but she is still refusing most meals now she is better. The last few days she’s probably had a weetabix a day, maybe with a few breadsticks, and her usual favourites like bananas, salmon, curry are just a complete no. I don’t know if something like teeth are behind it or it’s just toddler fussiness, but obvs keen to get her eating again. Any advice?!
