A missing tooth can be replaced in three main ways — an implant, a bridge or a denture. They differ in one important respect: what they do to the bone and to the teeth beside the gap.
Why replacing it matters
A gap is not only cosmetic. Neighbouring teeth drift into the space, the opposing tooth can over-erupt, chewing becomes uneven, and the jawbone in that area gradually shrinks because nothing is stimulating it.
Dental implant
An implant replaces the root itself with a titanium post in the jawbone, topped with a crown.
- Works like a natural tooth and preserves bone by stimulating it.
- Does not involve cutting down the healthy teeth beside the gap.
- Takes longer: about 10 to 14 weeks for a single tooth, because the bone must heal around the implant.
- Needs enough bone, which a 3D scan confirms.
Bridge
A bridge fills the gap using the teeth on either side as supports.
- Faster than an implant, with no surgery.
- The supporting teeth must be prepared, which means removing healthy tooth structure.
- It does not stop the bone beneath the gap from shrinking.
Denture
A removable replacement for one, several or all teeth.
- The least invasive and usually the quickest option.
- Removable, and it rests on the gums, so it can move while eating or speaking.
- Bone underneath continues to shrink over time, so dentures need adjusting or remaking.
How the choice is made
It depends on how many teeth are missing, the condition of the neighbouring teeth, the amount of bone, your general health and how long you can allow for treatment. For a full arch, implant-supported fixed teeth are an alternative to a conventional denture.
Common questions
Is an implant worth the longer wait? For many people yes, because it protects bone and leaves the neighbouring teeth untouched.
Can I have an implant years after losing the tooth? Often, though bone loss may mean grafting is recommended first.
What if I am nervous about surgery? The procedure is done under local anaesthesia and is painless; soreness for two to three days afterwards is normal.
