Laminate flooring recommendation?

I have a gap in my teeth.

My in-laws told me to get laminate flooring... They said if my teeth open up, it will cost money...

I was so stressed out that I went to the dentist for a consultation, and I heard that many people come because the elderly talk about it that wayㅠ

They say it's just to make it look nice..

They say I have to do it including root canal treatment.

Dentistry is really scary, you knowㅠ

Do many people do it?
