Tooth Filling treatment

What is Tooth Filling?

To treat a cavity, your dentist will remove the decayed part of the tooth, then “fill” the area of ​​the tooth where the decayed material has lived.

Fillings are also used to repair cracked or broken teeth and teeth that have been worn down due to improper use (such as nail bites or gnashing of teeth).

What Steps are Involved in Filling a Tooth?

First, the dentist numbs the area around the tooth with a local anesthetic. Then a drill, an air abrasion instrument or a laser will be used to remove the rotten area. The choice of instrument depends on the comfort level of the individual dentist, the training and investment in the particular equipment as well as the location and the extent of the cavity.

Then your dentist will probe or test the area during the decay elimination process to determine if all of the decay has been removed. Once the cavities are eliminated, your dentist will prepare the space for filling by cleaning the cavity of bacteria and debris. If the cavity is near the root, your dentist can first put on a glass ionomer, composite resin, or other lining to protect the nerve. Generally, once the filling is complete, your dentist will finish it and polish it.

Several additional steps are required for tooth-colored fillings and are as follows. After your dentist has removed the cavity and cleaned the area, the tooth-colored material is applied in layers. Then a special light which “hardens” or hardens each layer is applied. When the multilayer process is complete, your dentist will shape the composite material to the desired result, cut off any excess material, and polish the final restoration.

What Types of Tooth Filling Materials Are Available?

Today, several dental filling materials are available. The teeth can be filled with gold; porcelain; silver amalgam (which consists of mercury mixed with silver, tin, zinc, and copper); or dental, plastic, and glass materials called composite resin fillings. The location and extent of decay, the cost of the filling material,
patient insurance coverage and your dentist’s recommendations help determine the type of filling that will best suit your needs.

Cast Gold
Durability – lasts at least 10 to 15 years, usually longer; does not corrode.

Strength – can withstand chewing forces.

Aesthetics – some patients find gold more attractive than silver, amalgam fillings.

Expenses – more than other materials; up to 10 times higher than the cost of amalgam deposits

Additional office visits – Requires at least two office visits to place.

Galvanic shock – a gold filling placed right next to a silver amalgam filling can cause acute pain (galvanic shock). The interaction between metals and saliva causes an electric current, it is rare, however

Aesthetic – most patients find no “colored” fillings as an “eye-pleasing” benefit.

Silver-fillings (Amalgams)
Durability – lasts at least 10 to 15 years and generally survives composite fillings

Strength – can withstand chewing forces

Expense- is cheaper than composite fillings

Silver-fillings (Amalgams)Disadvantages:
Poor aesthetics – fillings do not match the color of your natural teeth

Destruction of more tooth structure – healthy parts of the tooth often need to be removed to create a space large enough to hold the amalgam

Discoloration – amalgam fillings can create a grayish tint to the surrounding tooth structure

Cracks and fractures – although all teeth expand and contract in the presence of hot and cold fluids, which can ultimately cause cracking or fracture of the tooth,
amalgam the material compared to other fillers may experience a greater degree of expansion and contraction and lead to a higher incidence of cracks and fractures

Allergic Reactions – a small percentage of people, approximately 1%, are allergic to mercury in amalgam restorations

Tooth-Colored Composite fillings
Aesthetics – the shade/color of the composites can be closely matched to the color of existing teeth; is particularly well suited for use in front teeth or visible parts of teeth

Adherence to the dental structure – composite fillings chemically bond to the dental structure, providing additional support to the tooth

Versatility of use – in addition to being used as a filling material for cavities, composite fillings can also be used to repair chipped, broken or worn teeth

Preparation for sparing teeth – sometimes less tooth structure needs to be removed compared to amalgams when cavities are removed and the filling is prepared

Lack of durability – composite fillings wear out earlier than amalgams (lasting at least 5 years compared to at least 10 to 15 for amalgams); moreover,
they may not last as long as amalgams under the pressure of chewing and in particular if they are used as filling material for large cavities

Increased time spent on the chair – due to the process of applying the composite material, these fillings can take up to 20 minutes longer than the amalgams to
be placed

Additional visits – if composites are used for inlays or inlays, several office visits may be required

Flaking – depending on location, composite materials may flake off the tooth

Expenses – composite fillings can cost up to twice the cost of amalgam fillings

In addition to the colored resin composite fillings on the teeth, there are two other colored fillings on the teeth, ceramic and glass ionomer.
