The word filling is a general term used to restore a tooth using a chair side filling material. These days amalgam has been phased out because of its unfavourable effects on tooth enamel and we tend to use a resin based material called composite.
Composite can be used to repair cavities caused either by tooth decay, or holes or fractures caused by other reasons such as toothwear from clenching, grinding, erosion from the diet or reflux, or because of abrasion from heavy toothbrushing.
Depending on the depth of the problem, a local anaesthetic may or may not be applied.
Usually a rubber dam is first applied.Not every dentist uses a rubber dam when performing restorative treatments. Not all patients understand what rubber dams are or why they are used, however this is the gold standard way of filling application and is crucial in ensuring long term success of your restoration.Â
If I am placing a small filling towards the front of the mouth or close to the gum, a rubber dam may not be needed or possible to use. However, for most posterior teeth, it can be extremely advantageous. The pros of using a rubber dam are (see photo):
Rubber dams do require some additional time to place, however the benefits of using rubber dams far outweigh any disadvantages.
The procedure
The dentist removes the decayed portion of the tooth (if present), cleans the cavity, and sandblasts it with a power called Aluminium Oxide which greatly aids the retention of the filling. If the hole is between 2 teeth and the wall of a tooth needs tore repaired, a special matrix will be used to give the correct contour of the tooth so that it is built back to its natural tooth anatomy and this allows for it to be flossed and not food or plaque retentive. Â If the contact point between 2 teeth is not properly recreated, then secondary decay can persist at this site.
The aim is to restore the tooth’s function, prevent further decay, and help maintain oral health.
Different types of fillings include amalgam, composite resin, ceramic, and glass ionomer, each offering unique advantages in terms of durability, aesthetics, and cost. The choice of filling material depends on factors such as the location of the cavity, the extent of decay, and patient preference.
After receiving a filling, patients should practice good oral hygiene habits and attend regular dental check-ups to ensure the filling remains intact and the tooth remains healthy.
Dental fillings work by restoring teeth that have been damaged by decay back to their normal function and appearance. The procedure typically begins with the dentist numbing the area around the affected tooth with local anesthesia to ensure patient comfort. Next, the decayed portion of the tooth is removed using a dental drill or laser, leaving behind a clean cavity. The cavity is then prepared to receive the filling material, which can be made of various types such as amalgam, composite resin, ceramic, or glass ionomer. The chosen filling material is placed into the prepared cavity and shaped to match the contours of the tooth. For composite resin fillings, a special light is used to harden (cure) the material. Finally, the filling is polished to smooth out any rough edges and ensure a natural-looking appearance. This restores the tooth’s structure, prevents further decay, and allows the patient to resume normal dental function.
Dental fillings are materials used to fill cavities caused by tooth decay and restore the function and structure of damaged teeth. They can also be used to repair cracked or broken teeth and replace old or damaged fillings.
Common signs that you may need a filling include tooth sensitivity, pain when biting or chewing, visible holes or pits in your teeth, or dark spots on the surface of the tooth. However, only a dentist can accurately diagnose the need for a filling through a comprehensive dental exam.
There are several types of fillings, including amalgam (metal), composite resin (tooth-colored), ceramic, and glass ionomer. Each type has its own advantages in terms of durability, aesthetics, and cost. Your dentist can recommend the best option based on your individual needs and preferences.
The process of getting a filling is typically not painful, as the dentist will numb the area around the affected tooth with local anesthesia before beginning the procedure. You may feel some pressure or vibration during the drilling process, but you should not experience any pain.
The lifespan of a filling depends on factors such as the type of filling material used, the location and size of the filling, and your oral hygiene habits. With proper care and maintenance, fillings can last for many years before needing to be replaced.
Yes, you can usually eat and drink normally after getting a filling. However, it’s a good idea to wait until the anesthesia wears off completely to avoid accidentally biting or burning your mouth. Avoiding extremely hot or cold foods and beverages immediately after the procedure can also help prevent discomfort.
Tooth decay, also known as caries, is the primary condition that necessitates dental fillings. When bacteria in the mouth produce acids that erode the enamel, cavities form. Dental fillings are used to restore the damaged tooth structure and prevent further decay.
Some individuals may experience tooth sensitivity after getting a filling, especially with certain types of filling materials. This sensitivity typically resolves on its own within a few days to a week but can be managed with desensitizing toothpaste or fluoride treatments.
Fractured or cracked teeth may require fillings to repair the damage and restore the tooth’s strength and function. Fillings help prevent further fracturing of the tooth and protect the inner pulp from infection or damage.
