What is Tooth Filling: Overview, Benefits,‌ and ‍Expected Results

A tooth filling is a⁣ common⁣ dental procedure used to restore a decayed or damaged tooth back to ‌its original shape ‍and appearance, improve the strength of the tooth ‌and ‍prevent further damage. Dental fillings, also known as dental restorations, are commonly used to treat cavities and other oral issues.



Overview



Tooth fillings are ⁤made from different types of materials such ⁤as metal, plastic, porcelain, and composite resin. The most popular types​ of materials​ used for tooth fillings⁤ are amalgam and‌ composite resin. Amalgam fillings, also known as silver fillings, are made of a‌ mixture of metals including silver, zinc, copper,⁢ and tin. These​ fillings are fairly strong and durable but have the ⁤potential to cause discoloration of the teeth. Composite resin fillings, also known as white fillings, are⁤ made of ⁤a ‌mixture of plastic and glass particles and are a more aesthetically pleasing option as‌ they match the natural color of the ‍tooth.



Benefits



The most ⁢apparent ​benefit of tooth‍ fillings is preventing further decay and related problems. By filling a cavity, the decayed portion of the tooth is removed and the risk of further damage and decay is reduced. Other benefits⁢ of a tooth filling include:

• Restoring ⁤the shape and appearance ​of a tooth



• Improving‍ the strength of a tooth



• Relieving pain and‌ sensitivity



• Preventing tooth loss



• Improving ‌speech and the ability to chew



• Protecting surrounding tissues and teeth

Expected Results



The expected results of a tooth filling ⁢depend on the material used. All fillings can‌ last for ‌several years before⁢ needing to be replaced. Teeth with composite fillings can last up to 10 years,⁣ while amalgam fillings can last up to 15 years. The longevity of the tooth filling also ⁣depends on the⁤ patient’s oral health habits and lifestyle.



Regular checkups are crucial ⁣to maintaining the health of⁤ a filled tooth. Regular​ checkups are important because they allow the dentist to make sure the filling is still properly sealed and functioning. Regular checkups also allow the dentist⁤ to catch any potential problems before they become serious. ⁣



Tools Required



The tools and materials required for a tooth filling procedure vary depending on the type of ⁤material used.‌ Most materials⁢ used for⁤ tooth fillings require some form ​of special equipment such as ‌a high-speed drill or an acid etch to prepare the tooth for the filling. Other ⁤materials ⁣may require special ⁣tools ⁣such as a‌ curette or ⁣an ultrasonic scaler to smoothen the filling’s surface. In addition to the tools and ‍materials, dentists also use an anesthetic to lessen‌ any potential discomfort during the procedure.



Steps of the Procedure



The steps of the tooth filling procedure vary depending⁢ on the type of material used.‌ Most materials used for‌ dental fillings follow a similar procedure:

• The dentist will begin by numbing the ‌affected area with a‌ local⁢ anesthetic.



• The cavity or damaged tooth will be cleaned ‌and rinsed of any debris ⁤or bacteria.



• The dentist will drill out the damaged or decayed tooth to deepen the cavity and prepare it for filling.



• The filling material will be ⁣prepared and shaped to ensure it adequately fills the cavity.



• The ⁤dentist will place and ​secure​ the filling material.



• The dentist will harden and shape the filling material ‍to ensure it blends in with⁣ the rest of the tooth.



• Lastly, the dentist will check the bite and make any necessary⁤ adjustments.

Risks and Complications



Most tooth filling procedures are relatively safe and uncomplicated, however there​ are a few potential risks and complications that should be taken into consideration ⁣such as allergies to the ‍filling material, nerve damage, bacterial infections, and⁢ an inability to properly​ fill the cavity. Allergic reactions are rare but can ⁤be quite serious. Nerve damage is possible but highly unlikely. Bacterial infections are ⁤also uncommon but possible ⁤and can ⁢lead⁣ to further complications. An inability to properly ⁢fill ⁢the ⁢cavity can lead to further decay of⁤ the tooth if ‍not addressed.



Conclusion

Definition & Overview

A tooth filling is a procedure wherein the damaged and decayed part of a tooth is removed and the area is filled with a replacement material to protect against further damage and to restore the tooth’s appearance and function. The replacement material, which is called the filling, can be made out of gold, silver amalgam, composite resin, glass ionomer, or porcelain. Each type of material has its own set of advantages and disadvantages, which have to be weighed along with the patient’s specific considerations, to determine the most appropriate material to be used.

Who Should Undergo & Expected Results

Tooth fillings are used to fill the space in a tooth once the decayed or damaged part has been removed. This treatment is most commonly used to treat cavities, but it is sometimes used to repair cracked and broken teeth. Patients have various options when it comes to materials to be used, which include the following:

• Cast gold fillings are known for their durability and strength. These can last up to 15 years or even longer due to their natural resistance to corrosion. On the other hand, they are very expensive, needs a minimum of two dental visits to be completely placed, and sometimes causes galvanic shock during the treatment procedure.

• Silver amalgams are preferred for their durability and affordability, however, due to their colour, they do not blend well with the natural teeth.

• Composites are the better options for those who want more realistic-looking fillings. However, they only last up to 5 years and takes a long time and several office visits to be placed.

• Porcelain fillings are the material of choice for many patients. Although just as expensive as gold fillings, these combine the benefits of durability and aesthetics, offering patients very natural-looking fillings that can last up to 15 years or more.

• Glass ionomer fillings are made of acrylic, which is a glass type material most commonly used for paediatric patients and for fillings that need to be placed below the gum line. These fillings are designed to release fluoride as a way to protect the tooth from getting damaged and decayed again. However, it is not as durable as other materials used for fillings and is prone to wear and tear. Generally, glass ionomer fillings last for only five years or even less.

Aside from traditional fillings, there are also indirect and temporary fillings.

• Indirect fillings are composite fillings that are fabricated in a dental laboratory and thus need at least two dental visits to be placed. Indirect fillings are used in cases where the remaining tooth structure is insufficient to support a filling but the damage is not significant enough to require a crown. Indirect fillings come in two types, namely inlays and onlays, both of which are far longer lasting than traditional fillings with a lifespan of up to 30 years.

• Temporary fillings are used in cases that require several visits, such as a root canal or when the tooth’s pulp becomes irritated. Temporary fillings are placed to give the tooth and gums enough time to heal or the nerves to settle down before the permanent filling is placed. If a temporary filling is not used, there is a risk that the exposed tooth will become infected during the waiting period.

How Does the Procedure Work?

If you are going to get a tooth filling, it helps to know what you should expect during the procedure. The treatment begins with the administration of a local anesthetic, which effectively numbs the area around the affected tooth. The dentist will then use a drill, laser, or air abrasion instrument, depending on equipment availability and location of the decay, to gradually and carefully remove the decayed part of the tooth. After ensuring that all decayed parts have been removed, the dentist will start preparing the space so the filling can be placed. This entails removing all debris and bacteria from the area.

In some cases, the decayed part may reach near the root of the tooth, which can cause some sensitivity due to the close proximity to the nerves. If this is the case, the dentist may put a glass ionomer or composite resin liner, which purpose is to keep the nerve protected throughout the procedure. Once this is done, the filling can finally be placed and the tooth will then be polished.

However, some specific materials used for fillings may require additional work. For example, fillings that are tooth-coloured, such as porcelain ones, have to be applied in layers, with every layer ‘cured’ or hardened by a special light beam. Once the material is in place, the dentist will proceed to shaping it to achieve the desired result.

Possible Complications and Risks

There is a very small risk of complications in the placement of tooth fillings, except for silver amalgam fillings. Silver amalgam fillings have long been the subject of concern due to the risk of allergic reactions to the mercury content of the amalgam material. Mercury has been linked to a number of diseases such as Alzheimer’s and multiple sclerosis. However, dental professionals state that once the amalgam is mixed with silver, copper, tin, or zinc, the result is a stable alloy that have been in use to make fillings for over a hundred years. Although the risks are not scientifically proven, the FDA has warned against the potential dangers of mercury particularly to pregnant women, persons with existing health conditions, and individuals with naturally higher levels of mercury in their systems. These risks, however, can easily be avoided by discussing other options with dental care providers and by opting to use other tooth filling materials.

There are also some warning signs to watch out for after getting a tooth filling placed. Although it is normal to feel some pain and sensitivity after the procedure, if these symptoms persist longer than two to four weeks, it would be best to consult your dentist.
