I've got toothie issues and will need a root canal to be rid of this agonising sensitivity I have going on

After hearing how folk go through a root canal only to need it pulled out anyway I'm thinking I should save up a bit more and get the tooth pulled and get an implant instead. I'm vain about teeth and not keen on having a gap

Or is that just crazy thinking?

I have to add that going to the dentist makes me almost vomit with fear.
