A composite filling is a tooth-coloured restoration used to repair a tooth affected by decay, minor damage, or wear.

Composite resin is carefully matched to the shade of your natural teeth. Once placed, it blends with the surrounding enamel, making it a discreet option for restoring both front and back teeth.

A filling does not make a tooth immune to future decay, but it can remove the damaged portion and seal the area to help restore the tooth’s strength and function.

Tooth decay begins when bacteria in plaque produce acids that gradually weaken the enamel. If the process continues, a cavity may form and extend deeper into the tooth.

Early decay may not cause noticeable symptoms. As the cavity becomes larger, you may experience:

• Tooth sensitivity to hot, cold, or sweet foods
• Pain when biting or chewing
• Food becoming trapped in a particular area
• A visible dark spot or hole in the tooth
• Roughness or a chipped area
• Persistent tooth discomfort

Regular dental examinations allow us to identify decay before it becomes more extensive. Treating a cavity early may help preserve more of the natural tooth structure and reduce the risk of needing more complex treatment.

Composite fillings offer several advantages:

• Natural appearance: The material can be matched to your tooth colour.
• Conservative treatment: Composite can often be bonded directly to the tooth, allowing us to preserve healthy tooth structure.
• Versatile use: Composite fillings may be used to repair cavities, small chips, worn areas, and minor cosmetic concerns.
• Comfortable function: A properly placed filling restores the tooth’s shape and helps you chew normally.
• Mercury-free material: Composite resin does not contain amalgam mercury.

The most appropriate filling material depends on the location and size of the cavity, the condition of the tooth, your bite, and your individual needs.

Before placing a filling, your AltaVia Dental team will examine the tooth and may take digital X-rays to assess the extent of the decay.

During treatment, the area is carefully numbed for your comfort. The decayed portion of the tooth is removed, and the remaining tooth is cleaned and prepared. Composite resin is then placed in layers, shaped to restore the tooth’s natural contours, and hardened with a curing light.

Finally, we check your bite and make any necessary adjustments so the filling feels comfortable when you chew.

Most composite fillings can be completed in a single appointment, although treatment time depends on the number and size of the fillings being placed.

Good oral hygiene helps protect both your filling and the surrounding tooth.

We recommend:

• Brushing twice daily with fluoride toothpaste
• Cleaning between your teeth every day
• Limiting frequent sugary snacks and drinks
• Wearing a mouthguard if you grind your teeth or participate in contact sports
• Attending regular dental examinations and professional cleanings

Composite fillings are durable, but like any dental restoration, they can wear, stain, chip, or require replacement over time. Regular visits allow us to monitor your fillings and identify concerns early.

Composite fillings are a common treatment for small to moderate areas of tooth decay. However, a larger cavity or a tooth that has been significantly weakened may require a different restoration, such as an inlay, onlay, or dental crown.

Your AltaVia Dental team will assess the tooth and explain the treatment options that are appropriate for your individual situation.
