As I age due to various causes, my teeth...
It seems like the color has changed, and I find it a bit unpleasant to look at.
But I heard that teeth can also be whitened.
It seems like you might use some medication for whitening, but is it safe?
Will it be okay? Does whitening last a long time?
If anyone has experience, I would appreciate it if you could let me know. Haha
