Bootstrap 4 Issue - Font Awesome icons not displaying

I can’t seem to get my Font Awesome icons to display on my page! I am making a dental website and want to use . I would like to place the icon at the top of each card in a three column layout (above “Cleanings” , “Fillings”, and “Whitening”)

My other Font Awesome icons for twitter and facebook are working on the page!

Here is a screenshot of my code in HTML. I have tried to put the icon in a div above the card div.

Any help is greatly appreciated!

You are using the correct CSS class names of “fas fa-tooth” to display a tooth icon.
Might want to ensure you have the correct link for the Font Awesome library.

Hey. Can you show the link
You inserted into the html head to connect to the font awesome library?
