After losing a tooth, it is quite common to have doubts about what to do to replace it. Should you replace it straight away? Is a dental implant worth the investment? Would a conventional bridge be a simpler option?
These are some of the most common questions patients ask when considering tooth replacement. The good news is that both dental implants and dental bridges are well-established, effective treatments that can restore missing teeth, improving function and providing excellent aesthetic results.
Why Is Replacing Missing Teeth Essential?
Losing a tooth is more than a cosmetic issue, especially if it is towards the back of the mouth. A single missing tooth can have long-term consequences as neighbouring teeth can gradually shift and the opposing tooth may begin to over-erupt into the empty space. Additionally, the jawbone in the area can start to shrink due to the lack of stimulation.
Over time, all these changes can affect your bite, oral health, and overall dental stability, which can affect self-esteem and quality of life while also potentially requiring more complex and costly treatment.
What Is a Dental Bridge?
A dental bridge is a prosthetic device that replaces one or more missing teeth by attaching one or more artificial teeth to the neighbouring natural teeth. This bridge traditionally consists of a replacement tooth called a pontic and two supporting crowns that are placed above adjacent teeth.
In contrast to other types of prostheses, the bridge is permanently fixed in place and cannot be removed by the patient.
What Is a Dental Implant?
A dental implant is designed to replace the root of a missing tooth. It consists of a small titanium screw that is placed into the jawbone.
Once the implant has healed and integrated with the bone, a custom-made crown is attached to restore the visible part of the tooth. Unlike a bridge, an implant does not rely on neighbouring teeth for support.
Dental implants are highly successful treatments that typically require a complete consultation and assessment, implant placement surgery, and a healing period of several months before attaching the final crown.
Dental implants that have successfully integrated with the jawbone can also support an implant bridge rather than replacing every tooth individually.
Dental Implants vs Bridges: Key Differences
While both options restore missing teeth, their approach is fundamentally different.
Effects on Adjacent Teeth
One of the biggest advantages of dental implants is that neighbouring teeth remain untouched. With a conventional bridge, healthy adjacent teeth often need to be reduced to accommodate the new crowns. Therefore, if preserving natural structure is a priority for you, you should consider dental implants instead of a bridge.
Jawbone Preservation
Dental implants help stimulate the jawbone by transmitting chewing forces in a similar way to natural tooth roots, maintaining the bone volume and density.
On the other hand, a bridge sits above the gum line and does not replace the tooth root, allowing bone loss to continue beneath the missing tooth area.
Treatment Time
A conventional dental bridge can often be completed within a few weeks from the first appointment to the final crown. Dental implants, on the other hand, generally take longer due to the healing and integration required before the final restoration is placed. Thus, if speed is your main priority, a bridge may be a quicker option.
Longevity
Both treatments can last for many years when properly maintained.
However, dental implants are generally considered the longer-term solution. While implant crowns may eventually require replacement, the implant itself can remain functional for decades and, in many cases, may last a lifetime.
Although bridges have excellent success rates, they are still susceptible to damage and decay over time.
Replacing a Single Missing Tooth
When replacing one missing tooth, a single dental implant is often considered the most conservative and effective solution. Some crucial factors considered in this decision are:
Adjacent teeth remain untouched
Bone is better preserved
Cleaning is similar to a natural tooth
The restoration functions independently of adjacent teeth
However, a traditional bridge may still be a suitable option if neighbouring teeth already require crowns or if implant placement is not possible for medical or anatomical reasons.
Replacing Multiple Missing Teeth
When several teeth are missing together, patients often assume they need one implant for every tooth. Yet, this is not always necessary.
Implant-Supported Bridges
Two or more implants can often support multiple replacement teeth. For example, three missing teeth may sometimes be restored using two implants and a three-unit implant bridge, allowing you to reduce the number of implants required while still providing excellent stability and function.
Conventional Bridges
Conventional bridges may also replace multiple missing teeth, provided the supporting teeth are strong enough to withstand the additional forces.
The suitability of either option depends on factors such as bone levels, tooth conditions, bite forces, and overall oral health.
Key Points to Consider
Dental implants help preserve adjacent teeth, maintain jawbone health, function similarly to natural teeth, and provide excellent aesthetics. However, they also take more time to heal and usually come at a higher price.
Conventional bridges are often more cost-effective, can usually be completed more quickly, and are highly durable, but often require the reduction of healthy neighbouring teeth and depend on the health of the surrounding teeth for their long-term success.
