Is it worth getting a crown on my dead tooth?

About 6 years ago I had a root canal done to my tooth. I think it’s called the lateral incisor (the tooth next to the two front teeth). Over the years I noticed it has started to darken and be weaker.

I went to the dentist the other day and they said to put a cap on it. They would have to literally shave my tooth and make it smaller and really skinny.

I’m really worried about them altering my tooth. They said that my cap will look real and that it should last 10 years and shouldn’t come off unless I got hit with a bat really hard lol. Only 5% of people had issues with their cap and my mom was one of them a few days ago :(.

I am worried I’ll look stupid with this cap and it won’t look real and I’m afraid that someone will see my skinny tooth. I don’t want to ever see that or have anyone see it.
