Question Help buttons in unity 3d

Hello guys,
I'm sorry for interrupting , I need some advice&help as soon as possible with my app, so basically I have a educational game where I model some teeth, and when i press on a teeth, my recorded voice will say some info about that particular teeth. I made this 2 scenes now, one is for a menu and the other is for the teeth. I need some advice, I want to make when I press play to get into the second scene and there I don't know how I can implement when i press a teeth, the voice and the teeth to show up .
Please -> Any help would be great!

You could make the teeth all separate game objects, and use the OnMouseDown() magic method to listen to a click on each one: https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnMouseDown.html

Your custom component can then play the correct audio clip.
