Composite fillings

Composite fillings are strong, but may not be as hard wearing as amalgam fillings. Composite fillings are tooth colored and are made from powdered glass quartz, silica or other ceramic particles added to a resin base. After the tooth is prepared, the filling is bonded onto the area and a light shone onto it to set it. The dentist will choose a shade to match your existing teeth, although over time staining can occur.

Procedure

Your dentist will give you a local anesthetic to numb the area. The dentist then prepares an access to the decayed area of the tooth and removes the decay and previously placed filling material.  With a composite filling, your dentist will preserve more of the natural tooth as the composite resin can be bonded to the tooth in thin layers. If your tooth's decayed area is close to a nerve, a special liner will be used to protect the nerve.
A special dental material is then used to open up the pores of your tooth's dentin and roughens up the surface of the exposed enamel. This achieves better and stronger bond. The bond resin is applied to stick the composite to your tooth. This material is made of the same dental resin as the composite however it is much more fluid. This layer is then hardened and cured with a very bright light.
Composite resin fillings are applied in thin layers, and slowly built up to form the complete filling. A bright dental light will harden each layer before the next is applied.
Once your filling is placed, your dentist will use a special paper to mark where the new filling is hitting too much. This is called being "high".  The dentist then adjusts the new filling so all your teeth come together properly. Your new composite filling is then polished.

Durability

Composite, resin or white fillings have been around for about two decades. Composite fillings have the advantage of requiring a more “conservative” tooth preparation (e.g., less drilling required); can have a strengthening effect on the tooth; are very aesthetic; and virtually blend in with the tooth. Composite fillings are the material of choice for repairing the front teeth. On the down side, they are more technique sensitive for the dentist to place and require more time resulting in more expense.
These resins typically last from 5-12 years before they begin to chip and wear away. When this happens, the restoration will need to be replaced.

sealants

A sealant is a protective, plastic material that is placed directly on the chewing surfaces of molars and premolars. Sealants protect tooth enamel from erosion and drastically reduce the occurrence of tooth decay.  
Teeth are prepared for sealants with a thorough cleaning, followed by the application of a specialized dental solution. This solution roughens the chewing surfaces, making it easier for the sealants to adhere to the teeth. The sealants are then painted on the chewing surfaces of the teeth and a curing light is used to harden the sealants.
As long as the teeth receive regular care, sealants can last several years before requiring a reapplication.

dental bridge

A dental bridge is one method used to replace one or more missing teeth in the patient’s mouth.  The teeth on either side of where a tooth is missing are prepared so there is room for the bridge to be placed and permanently cemented to them.  The bridge may be made of semiprecious metals with porcelain baked to it to match the remaining teeth. Or it may be constructed entirely of porcelain for a very esthetic result!

How is dental bridge accomplished?

Your dentist will prepare your teeth on either side of the space for placement of the bridge.  You will be given a mild anesthetic to numb the area, and the dentist will remove tooth structure from each abutment (teeth on either side of the space) to accommodate for the thickness of the bridge. When these teeth already have fillings, part of the filling may be left in place to help as a foundation for the bridge.The dentist will then make an impression, which will serve as the model from which the bridge will be made by a dental laboratory. A temporary bridge will be placed for you to wear while your bridge is being made until your next visit. This temporary bridge will serve to protect your teeth and gums and prevent the teeth that support the bridge from moving.
On your second appointment, the temporary bridge will be removed. Your new permanent bridge will be fitted and checked and adjusted for any bite discrepancies. Your new bridge will then be cemented to your teeth.
