There are times when it makes sense to extract a tooth and replace it with a dental implant.
If a natural tooth is failing or about to fail.
If a tooth has severe periodontal disease (gum disease) that has eroded the bone that supports the teeth. Sometimes in these cases, it is preferable to extract the teeth, eliminate the disease and infection, and replace the teeth with a dental implant.
When a tooth has had a root canal (nerves have been removed from the tooth) leaving the tooth brittle and susceptible to fracture. Teeth with severe fractures are usually extracted and are ideal candidates for replacement with dental implant treatment.
