Can people with dental phobia get teeth whitening?

hello.

I am a non-smoker and I am worried about the yellow color of my teeth, even though there is no specific reason.
I've been thinking more and more these days about getting my teeth whitened, even if it's just for the sake of a good first impression or a clean image.
But I've had a severe fear of dentists since I was little, so I don't have the courage to go.

What worries me most is the pain.

Will my teeth feel sensitive or painful when I get teeth whitening treatment?
Just hearing the machine noise is scary, and I'm worried that it might hurt.
And I'm also worried that teeth whitening might wear away the outer surface of my teeth or have a negative impact on my dental health.

Is there a teeth whitening treatment that even a timid person like me can comfortably receive?
Would it be too much to ask for a safe way to get it done without side effects or this tingling sensation?
I'm really curious to hear real reviews from people who have had teeth whitening treatment.

I would like to ask for valuable information on how painful it is and whether post-procedure care is difficult.
