Thanks for this valuable information! I didn't know that if you put oil on your teeth, they get whiter.
And talking about the options when you have a missing tooth, I think it all depends on the condition of other teeth. Recently, I got an implant, and I'm happy with it. Before that, I ate a nut, and my tooth fell. It's good that I found an article about how to make a temporary tooth filling. It helped to caution against inflammation.
