Short answer
Where enough healthy tooth structure remains and the root is sound, keeping the tooth with root canal treatment is usually preferred because a natural root preserves the bone and the bite. Removal makes more sense when the tooth is fractured below the gum, severely decayed, or has lost too much support.

Why keeping a tooth matters
A natural tooth root keeps the surrounding bone stimulated and holds its neighbours in position. When a tooth is removed, the bone in that spot gradually shrinks and the teeth either side can drift, which changes the bite over time.
That is why dentists start from the question 'can this tooth be saved?' rather than 'should it come out?'
When removal is the better call
A tooth cracked vertically down into the root, one that has lost most of its structure to decay, or one with advanced gum disease and little bone support may not be restorable. Treating it would mean spending time and money on a tooth that is unlikely to last.
In those cases, planned removal followed by a considered replacement is often the more durable path.
What happens to the gap
If a tooth is removed, the conversation immediately moves to what replaces it: an implant, a bridge, or a denture, depending on the site, the bone and your preferences. Leaving a gap has consequences for chewing and for the teeth around it.
Ask for the replacement to be planned at the same time as the extraction, so you know the full path and the full cost before anything starts.
Questions to ask your dentist
Is this tooth restorable, and what makes you say so? What would the tooth need afterwards — a crown? What is the realistic outlook for each option? And if it comes out, what replaces it and when?
A good answer covers both routes honestly rather than pushing one.
