White Fillings
What Is a White Filling?
Dental fillings treat cavities by filling the damaged area once the decay has been removed, restoring both appearance and function. Initially, white fillings were only suitable for front teeth due to durability concerns. However, advancements in dental technology have led to stronger fillings that can now support back teeth as well. Beyond aesthetics, fillings repair tooth damage.
White fillings are modern alternatives to amalgam fillings, which are made from a mixture of metals, resulting in a silver, metallic appearance. In contrast, white fillings are made from porcelain or composite resin, which matches the natural colour of your teeth.
Patients often choose white fillings over amalgams for cosmetic reasons, aiming for a natural-looking smile. Porcelain white fillings are stronger than amalgams, while composite materials, especially when reinforced with glass ceramics, provide stability and comfort.
What Happens During a White Filling Procedure?
During a white filling procedure, your dentist will first conduct assessments, which may include X-rays. This is to ensure you receive the best care and appropriate treatment. The procedure involves the following steps:
- Local Anaesthetic: This numbs the area around the affected tooth, ensuring a comfortable, pain-free experience during the procedure.
- Removing Decayed Material: The dentist will use a drill, laser, or air abrasion instrument to remove decayed material from your tooth. This is crucial for properly placing the filling and preventing infection spread.
- Final Clean-Up and Preparation: The dentist will check that the area is free of excess material and bacteria. If decay is near the root, a protective liner made from composite resin or glass ionomer may be applied.
- Placing the Filling and Polishing: The filling is placed in layers, with each layer bonded and cured using a special light. Resin is then applied to strengthen the bond, and the tooth is polished to achieve the desired shape and natural look.
How to Care for Your Teeth and Fillings After the Procedure
While the white filling procedure is safe and pain-free, you might experience some discomfort once the anaesthetic wears off. Over-the-counter painkillers can help, but consult your dentist if you have concerns.
If you notice any issues with your teeth post-procedure, make an appointment with your dentist for further evaluation and treatment.
Proper oral hygiene is essential to maintaining your fillings. Brush and floss daily, use mouthwash to eliminate bacteria, and visit your dentist every six months to keep your fillings strong and effective.e.
