Dental bridges advantages
Restoring missing teeth with dental bridges has many advantages. Well-executed and properly maintained, bridges ensure high comfort and aesthetics and patients get accustomed to them in a short time.
Bridges are fixed prosthetic restorations that do not require periodic removal for cleaning
Because of this advantage, many patients prefer them against removable dentures. Bridges are permanently fixed by cementing the anchor crowns to the abutment teeth and there is no need for periodic removal.
Many patients are more comfortable with the idea of a fixed restoration rather than a removable one.
Patients get used to dental bridges in a short time
Bridges are small and lightweight dental restorations. After the definitive cementation, getting used to dental bridges takes less time than in case of removable dentures (or other more complex restorations) which are larger and heavier.

Dental bridges provide excellent chewing comfort
This is because all chewing forces are passed to the abutment teeth and not to the gums underneath. Therefore, teeth perform the mastication, which is the natural way. By contrast, removable dentures rest exclusively on the gums so the chewing process (or part of it) is performed on the gums.
Aesthetics are very good
When aesthetic demands are high, it is advisable to opt for porcelain or zirconium-based bridges, which are aesthetically superior.
Few appointments are needed
Bridges can be completed in two sessions, while removable dentures need at least 4 appointments to be completed. Dental implants need 3 to 6 months after the surgical insertion to fuse with the bone through a biologic process called osseointegration.
Lifespan and prognosis are good
To ensure this goal, dental bridges need to be properly maintained.
Dental bridge disadvantages
Bridges require the preparation of the abutment teeth
To ensure the bridge support and insertion, the abutment teeth need to be properly prepared. This operation involves permanently removing much of the tooth's original structure, including portions that might still be healthy and structurally sound.
It's the biggest disadvantage as it leads to the loss of large amounts of healthy tooth tissue and sometimes even tooth devitalization and endodontic treatment. Therefore, restorations supported exclusively by dental implants have the big advantage that teeth adjacent to the gap remain untouched.
This disadvantage stands out especially when abutment teeth are perfectly healthy without any fillings or cavities.
The abutment teeth may show increased sensitivity to external stimuli
Usually, after the preparation, one or more temporary crowns are constructed. These devices will protect the abutment teeth until the definitive restoration is completed.
If no temporary restoration was designed, abutment teeth may show an increased sensitivity to hot or cold stimuli until the bridge is definitively cemented.
