Implant, Bridge, or Denture: An Honest Comparison

A worked example is in Implant or bridge for one missing tooth.

The effect on bone is a separate question from longevity, and it starts the day the tooth comes out. In a systematic review by Tan and colleagues, an extraction socket left to heal on its own lost roughly 29 to 63 percent of ridge width and 11 to 22 percent of ridge height in the first six months. That shrinkage continues under a bridge and is what an implant is placed to interrupt.

Side by Side

The longevity figures below come from long-running reviews rather than from any one office. A systematic review by Pjetursson and colleagues found conventional tooth-supported bridges surviving at 93.8 percent over five years and 89.2 percent over ten, with decay and loss of pulp vitality in the supporting teeth the most frequent complications. A review by Jung and colleagues of single crowns on implants reported implant survival of 97.2 percent at five years and 95.2 percent at ten.

	Dental implant	Fixed bridge	Removable partial denture
What holds it	A titanium post in the jaw	Crowns on the two neighboring teeth	Clasps on remaining teeth and the gums
Effect on neighbors	None	The neighbors are ground down for crowns and carry extra load	Clasps can stress and loosen the teeth they hold
Effect on bone	Largely preserves it; some remodeling still occurs	Bone under the missing tooth continues to shrink	Bone shrinks, and pressure from the denture can speed it up
Cleaning	Brush and floss like a tooth	Floss threaders under the false tooth	Remove and clean daily
Feel	Like a tooth	Like teeth, once adjusted	A foreign object, especially at first
Time to complete	3–6 months	2–4 weeks	2–6 weeks
Typical lifespan	Decades, with maintenance	10–15 years	5–7 years

When a Bridge Is the Better Choice

• The neighboring teeth already need crowns, so nothing healthy is sacrificed.
• There is not enough bone for an implant and you do not want grafting.
• A medical condition makes surgery inadvisable.
• Time matters more than longevity.

When a Removable Partial Makes Sense

• Several teeth are missing across the arch and implants are not affordable now.
• As a transition while implants heal.
• When remaining teeth have a limited prognosis and a larger plan is coming.

When an Implant Is the Clear Choice

• One tooth is missing and the neighbors are healthy.
• You want to preserve bone in a visible area.
• A bridge has already failed once.
• You want the option that needs the least attention over a lifetime.

How We Decide with You

The consult looks at all of it: the bone, the neighboring teeth, your bite, your health, your budget, and what you are willing to maintain.
