Dental Fillings 
If part of a tooth has been lost through decay or damaged due to an accident, your dentist may put in a dental filling. Dental fillings are used to fill a portion of tooth or plug the hole and stop any future pain or discomfort.
Types of Dental Fillings
There are two basic types of dental fillings:
Procedure for Composite Resin Dental Fillings Treatment
The course of treatment described here is one of several options available at our dental clinic.
- First evaluation and fillings tooth preparation
- decay in tooth is removed and clean cavity of bacteria and debris
- prepare space for the filling
- Application of dental fillings
- tooth-colored material is placed in layers
- a special light that "cures" or hardens each layer is applied
- shape composite material to the desired result, trim off any excess material
- polish final restoration
Recovery Expectations
Having dental fillings and fillings replacement done is a quick and relatively simple process. There should be little or no sensitivity in teeth.
Dental fillings treatment can usually be completed within one visit if warranted. If however, there are a large number of fillings, the visits may be separated for better patient comfort.
Care for Dental Fillings
To maintain your fillings, you should follow good oral hygiene practices:
- Brush at least twice a day. It is good practice to brush after eating and before bedtime.
- Floss at least once to twice a day.
- See your dentist for regular professional check-ups and cleanings. If your dentist suspects that a filling might be cracked or is "leaking", further assessment of the situation should be done
- If your tooth is extremely sensitive, if you feel a sharp edge, if you notice a crack in the filling, or if a piece of the filling is missing, call your dentist

Traditional Amalgam Fillings
Most of us have had amalgam fillings (silver) . Amalgam fillings are sometimes called mercury fillings as some amalgam fillings contained minute amounts of mercury.
|
Advantages
- Strength – can withstand chewing forces
- Expense – is less expensive than composite fillings
|
|
Disadvantages
- Poor aesthetics – does not match the color of your natural teeth
- Destruction of more tooth structure – healthy parts of the tooth may need to be removed to make a space large enough to hold the amalgam filling
- Discoloration – amalgam fillings can create a grayish hue to the surrounding tooth structure and tend to blacken over time
- Rare Allergic reactions – a small percentage of people, approximately 1%, are allergic to the mercury present in amalgam restorations

Composite Resin Tooth-Colored Fillings
Composite resin dental fillings or white fillings are tooth fillings colored to look like a natural tooth.
|
|
Advantages
- Aesthetics – shade/color can be matched to existing teeth? well suited for front teeth use
- Versatility in uses – in addition to use as a filling material for decay, composite fillings can also be used to repair chipped, broken or worn teeth
- Tooth-sparing preparation – less tooth structure may need to be removed compared with amalgams
|
|
Disadvantages
- Increased treatment time – because of the process to apply the composite material
- Chipping – depending on location, composite materials can chip off the tooth
- Expense – composite fillings cost up to 150 % the cost of amalgams
