Losing a tooth — whether through decay, injury, or gum disease — can affect far more than your appearance. It changes the way you chew, can alter your speech, causes neighbouring teeth to shift, and over time leads to bone loss in the jaw. Dental implants offer a solution that addresses all of these concerns, providing a result that looks, feels, and functions like a natural tooth.
Despite being increasingly common, implants are still surrounded by questions and misconceptions. This guide explains clearly what they are, how they work, who they suit, and what the experience of getting one actually involves.
What exactly is a dental implant?
A dental implant is a small titanium post — roughly the size and shape of a tooth root — that is surgically placed into the jawbone. Titanium is used because it is biocompatible, meaning the body accepts it and bone tissue naturally fuses to it through a process called osseointegration.
Once the implant has integrated with the bone (typically over three to six months), a connector piece called an abutment is attached to the top of the post. A custom-made crown, bridge, or denture is then secured to the abutment, completing the restoration. The result is a tooth that is indistinguishable from its neighbours in both appearance and function.
How do implants compare to other options?
Dental bridge: A bridge fills the gap by crowning the teeth on either side and suspending a false tooth between them. It does not require surgery, but it permanently alters healthy adjacent teeth and does not prevent bone loss in the jaw.
Partial denture: A removable appliance that clips onto remaining teeth. More affordable upfront, but many patients find them uncomfortable, unstable, and inconvenient to remove for cleaning.
Dental implant: Standalone, permanent, and self-supporting. It preserves bone, requires no modification of adjacent teeth, and is cared for exactly like a natural tooth.
Who is a good candidate?
Most healthy adults with a missing tooth or teeth are potential implant candidates. The key requirements are:
Adequate jawbone volume: The bone needs to be thick and dense enough to support the implant. If bone loss has occurred, a bone graft may be carried out first.
Healthy gums: Active gum disease must be treated before implant placement.
Good general health: Uncontrolled diabetes, certain blood disorders, and some medications can affect healing. Your dentist will review your medical history carefully.
Non-smoker or willing to quit: Smoking significantly reduces implant success rates by impairing healing and increasing infection risk.
The treatment timeline step by step
Understanding what to expect makes the process far less daunting:
Consultation and planning: 3D scans and X-rays are taken to map the bone, nerves, and anatomy of the jaw. A detailed treatment plan is created.
Implant placement: Under local anaesthetic (and sedation if preferred), the titanium post is placed into the bone. The procedure is typically completed in under an hour per implant.
Healing and osseointegration: Over the next three to six months, the bone grows around and bonds to the implant. A temporary restoration may be worn during this time.
Abutment placement: Once integration is confirmed, the abutment is attached. Minor gum healing follows over one to two weeks.
Final restoration: An impression is taken and your custom crown is fabricated and fitted. The result is checked for fit, bite, and aesthetics.
How long do implants last?
With proper care, dental implants can last decades — many patients keep them for life. The crown on top may eventually need replacement after 15 to 20 years due to normal wear, but the implant itself is designed to be permanent. Brushing, flossing, and regular dental visits are all that is needed to maintain them.
