Do You Need a Post Crown?
If you have a root-filled tooth, a post might be needed for support before placing the crown. Posts can be prefabricated from stainless steel or custom-made to fit your tooth precisely. Once in place, the crown is securely attached.
How Long Will a Crown Last?
A crown’s lifespan depends on how well you care for it. While the crown itself won’t decay, decay can occur where the crown meets the tooth. With good oral hygiene, crowns can last 10-20 years.
Bridges

Dental bridges replace missing teeth, offering an alternative to dentures and implants. A bridge fuses crowns or partial crowns with an artificial tooth, restoring both function and appearance. Longer bridges may have a shorter lifespan due to the risk of fracture.
The Benefits of Dental Bridges
Choosing a dental bridge offers many benefits:
- Restores the look of a complete, healthy smile.
- Supports your bite, making it easier to eat and speak.
- Helps maintain the shape of your face.
- Prevents surrounding teeth from shifting into the empty space.
- Reduces the risk of decay and gum disease in remaining teeth.
- Offers a cost-effective alternative to dental implants.
By filling the gap, a dental bridge strengthens your smile and supports your long-term oral health.
Can a Bridge Always Replace Missing Teeth?
Not everyone is a candidate for a bridge. We’ll assess your teeth and bone structure to ensure a bridge is the best option for you.
Materials Used for Crowns and Bridges
Crowns and bridges are made from resin, ceramic (Including Zirconia & Emax materials), metal alloy, or a combination of ceramic bonded to metal. This mix offers both strength and an attractive appearance.
Onlays

An onlay is a type of indirect dental restoration that repairs a tooth with extensive decay or damage, particularly when the damage is too significant for a filling but not severe enough to require a full crown. Sometimes referred to as “partial crowns” because they cover one or more cusps (the raised points) of the tooth.
Unlike traditional fillings, which are applied directly to the tooth, onlays are fabricated outside the mouth—typically from materials such as porcelain, composite resin, or gold—before being bonded onto the affected tooth.

How Are Crowns , Onlays and Bridges Made?
Traditionally, crowns, bridges & onlays take two weeks to make, with tooth preparation and impressions sent to a lab. However, at Larkham House, we can use digital dentistry to create and fit your crown or bridge on the same day, eliminating the need for temporary solutions.
Caring for Your Crowns, Onlays and Bridges
Daily cleaning under your crown and bridge is essential to prevent issues like bad breath and gum disease. We’ll show you how to use special tools like bridge needles or super floss. Regular check-ups will help catch and address any potential problems early.
