Saving a Tooth or Extracting It
When a tooth is badly damaged there are usually two options: treat it and keep it, or remove it and decide how to fill the space. People often assume extraction is the cheaper and simpler route. Sometimes it is. Frequently it is the more expensive one once the consequences are counted.
What decides whether a tooth can be saved
How much sound tooth is left above the gum. This matters more than anything else. A crown needs something to grip. If the remaining structure is largely at or below gum level there may not be enough to hold a restoration, however healthy the root is.
Where the crack runs. A crack confined to the crown is usually restorable. One running vertically down the root generally is not, because it creates a permanent channel for bacteria that no filling material can seal.
The supporting bone. A structurally perfect tooth that has lost most of its bone support to gum disease is not a good candidate for expensive restoration. It will loosen regardless.
Whether the root can be sealed. Root canal treatment works by cleaning and sealing the canal system. Severely curved, calcified or previously treated canals reduce the odds.
Root canal treatment, and what it actually is
A root canal removes infected or dead pulp from inside the tooth, cleans and shapes the canal, and seals it. The tooth stays in place and continues to function. Its root remains in the bone, which means it goes on maintaining that bone in a way no replacement except an implant does.
The reputation the procedure has is largely out of date. Most of the pain people associate with root canals is the pain of the infection that made one necessary, and the treatment relieves it. A root treated tooth is more brittle afterwards because it has lost internal structure and its blood supply, so back teeth usually need a crown to stop them splitting. That crown is part of the cost and should be in the quote from the start.
When extraction is the better decision
Sometimes keeping a tooth means spending significantly on something with a poor prognosis. A tooth that is cracked below the gum, has lost most of its bone support, or would need root canal, post, core and crown while still being questionable, is often better removed. Wisdom teeth are their own category and frequently come out because they cannot be cleaned reliably rather than because they are damaged.
The important point is that an extraction is a decision about the whole mouth, not just that tooth.
What happens to the gap
This is the part that gets underestimated. A space is not stable. The teeth either side drift and tip into it, and the tooth in the opposing jaw over-erupts because nothing meets it. Tipped teeth are harder to clean and trap food, which invites decay and gum problems in teeth that were previously fine. The bone in the gap also resorbs over time, because nothing is transmitting chewing force into it.
That is why replacement gets discussed at the same time as extraction rather than afterwards. The realistic options are an implant, a bridge or a denture, and they differ in cost, in whether neighbouring teeth are involved, and in whether bone is preserved.
Not every gap needs filling. A missing wisdom tooth generally does not. A missing molar further forward usually does. That judgement is part of the conversation.
