Protect your teeth with Dental crowns & Bridges

 

A dental crown protects and supports weakened tooth structure while dental bridges replace missing teeth.

Both treatments involve restoring your biting functions and are aesthetically similar to your natural teeth.

WHAT IS A DENTAL CROWN?

 

A dental crown is a tooth-shaped prosthesis that covers over and protects your entire tooth, restoring your tooth to its original shape.

WHEN DO YOU NEED DENTAL CROWNS?

Dental crowns may be recommend in the following scenarios when:

  • A weak tooth needs protection so it does not break apart
  • A broken or severely worn down tooth needs to be restored
  • A tooth with a large filling needs to be covered and supported
  • A dental bridge needs to be held in place
  • A severely discoloured or misshapen tooth needs to be covered
  • A dental implant needs to be covered

TYPES OF DENTAL CROWNS

At Dentists Co, we provide a variety of dental crowns that are made from a wide range of materials.

Zirconia Crowns

These crowns offer the best combination of strength, aesthetic appearance and durability, with the ability to withstand very heavy masticatory forces generated on the molar teeth. They are white-coloured, but also more opaque, making them slightly brighter in comparison to natural teeth.

Porcelain or Ceramic Crowns

The most natural-looking and visually aesthetic option, these crowns are a popular and common choice for patients. They also excel in terms of strength and durability. These crowns can be bonded onto the tooth enamel for extra strength and retention, thus requiring less tooth structure to be removed.

Resins Crowns

These crowns are made from tooth-coloured polymer resins with a similar appearance to natural teeth—however, they will lose their shine over time. The main advantage of resin crowns is that very little or no tooth structure needs to be removed. While the overall strength of the crown material is suitable for everyday life, it is less strong than that of other crowns.

Gold Crowns

Gold dental crowns have been used to restore damaged teeth for thousands of years. Gold crowns provide an excellent balance between strength, safety and durability. However, a potential drawback is their metallic golden appearance, which may not appeal to patients nowadays.

Porcelain Fused-to-Metal Crowns (PFM)

These crowns are typically made from a mixture of non-precious metal alloys consisting of nickel, cobalt or chromium, that is then covered with a layer of porcelain to achieve a white appearance. However, they require extensive removal of the healthy tooth structure as they need to be prepared in thick sections to allow space for both layers of metal and porcelain.

DENTAL CROWN TREATMENT & PROCEDURE

The placement of a dental crown will require at least 2 dental visits and involves several steps.

  • Your First Visit

    Your dentist prepares the tooth by trimming, shaping and removing any decay from it. Next, your dentist may build the core of the tooth to support the crown with additional tooth structure if needed. An impression will be taken from a mold or digital scan to provide an exact model for both your temporary and permanent custom-made crown. Your dentist will discuss with you the best natural colour for your crown, and a temporary crown will be fitted while the permanent crown is created and completed in 2 weeks' time.

  • Your Second Visit

    When your new permanent crown is ready, your dentist will replace your temporary crown with the permanent crown. Once you find the fitting satisfactory, the crown will be cemented and any excess cement will be removed.

WHAT IS A DENTAL BRIDGE?

A dental bridge typically consists of two or more specially fitted crowns that are placed on the abutment or anchoring teeth on either side of the space formed by your missing tooth or teeth.

WHEN DO YOU NEED DENTAL BRIDGES?

Dental bridges may be recommend in the following scenarios:

  • To replace several missing adjacent teeth
  • To distribute the forces in your bite properly by replacing missing teeth
  • To prevent remaining teeth from drifting out of position

TYPES OF DENTAL BRIDGES

Dentists Co provides different types of dental bridges that are made from a variety of materials.

traidtional-dental-bridge

Traditional Bridges

A traditional bridge is the most popular type of dental bridge for restoring lost teeth and can be used when you have natural teeth or implants adjacent to your missing tooth. They are usually small, lightweight and provide excellent chewing comfort by redistributing your normal bite force compromised by your missing teeth.

Cantilever-dental-bridge

Cantilever Bridges

A cantilever bridge is supported by a single abutment tooth and spans the gap left by a missing tooth. This bridge is not as strong as a traditional bridge and cannot bear the full force of a bite; therefore, they are not usually recommended for back teeth. Typically, dentists only use this bridge to replace single missing teeth.

Maryland Bridges

Often referred to as resin-bonded bridges, a maryland bridge has a wing-like structure and is made from plastic teeth and gums supported by a metal framework. Metal attachments located on opposing sides are bonded to existing anchor teeth. This bridge is mainly used on front teeth, in cases where the adjoining teeth are in stable condition.

implant-support-bridge

Implant Supported Bridges

As its name suggests, an implant supported bridge is supported exclusively by dental implants, with no need for support by dental crowns or bulky substances. Since there is typically no damage to adjoining natural teeth, these bridges have gained popularity over the years. This bridge also allows for adequate spacing between the dental implants for easy cleaning and maintenance and, if integrated well, are incredibly stable.

Composite-Bridges

Composite Bridges

A composite bridge is a suitable option for those looking for a simple and affordable solution to replace one or two missing teeth. This bridge can usually be made and installed in a single dental visit, where a composite bonding material (plastic tooth filling) is placed directly into the missing space.

DENTAL BRIDGE TREATMENT & PROCEDURE

The process of placing a dental bridge is similar to that of a dental crown.
The placement of a dental bridge will require at least 2 dental visits.

  • Your First Visit

    Your dentist will prepare your teeth by trimming and reshaping them. The impression of your abutment tooth or teeth will then be used to create a customised model for your dental bridge. The abutments will be fitted with a temporary prosthesis, and your dentist will discuss which tooth colour is best suited for your dental bridge.

  • Your Second Visit

    Your dentist will replace the temporary prosthesis with your final cutomised dental bridge and adjust your bite and fit. When you are satisfied with the fitting, the dental bridge will be cemented permanently in place, and any excess cement will be removed.

POST-TREATMENT CARE FOR CROWNS AND BRIDGES

Dental crowns and bridges are designed to beautify your smile without hindering your lifestyle. Here are some tips for maintaining your dental crowns or bridges after your treatment.

dental-crown-bridge-malaysia-dentistsco

Maintaining Oral Care

Just like with your natural teeth, it is important to keep the gums around the crown or bridge healthy, so regular and proper brushing and flossing is essential.

Be careful when biting on extremely hard items like bones or crabs with your crown or bridge as there is a risk of chipping any porcelain portions.

It is advisable to go for regular checkups every 6 months for your dentist to monitor the crown or bridge condition.

Observe Signs to Replace Dental Crowns or Bridges

Schedule an appointment with your dentist to check or replace your dental crown or bridge if you experience any signs below:

  • Your bite feels 'off' or uneven.
  • You experience pain and discomfort where your dental crown or bridge is placed.
  • You notice wear and tear on your crown.
  • Your crown is ten years old, or older.
  • Your crown looks old and worn out.

FAQS

Make sure to consult your dentist for a comprehensive examination of your oral condition before determining if you should undergo treatment to get dental crowns or bridges.

As a rough guide, dental crowns may be recommend in the following scenarios when:

  • A weak tooth needs protection so it does not break apart
  • A broken or severely worn down tooth needs to be restored
  • A tooth with a large filling needs to be covered and supported
  • A dental bridge needs to be held in place
  • A severely discoloured or misshapen tooth needs to be covered
  • A dental implant needs to be covered
On average, dental crowns can last between 5 to 15 years depending on your personal lifestyle, physical habits, oral hygiene practices and the durability of the dental crown.

Getting a dental crown or bridge is not known to be a painful experience at all. However, if you are afraid of any pain, you may request for local anaesthetic from your dentist when placing the crown.

As with your natural teeth, the covered area of the tooth under the dental crown is still vulnerable to cavities. 

If a cavity forms under your dental crown or bridge, your dentist will remove the placement so that the cavity can be treated.
