Dental Fillings for Kids

The Filling Process

At Richmond Hill Kids Dentistry and Orthodontics, we typically use tooth-coloured composite fillings  to repair a cavity. These fillings are durable, can withstand moderate pressure of chewing, and blend in with the natural tooth. 

When a filling is required, we will begin by placing a local anaesthetic to the area so your child won't feel any pain. Once it has taken effect, we will thoroughly remove all decay from the tooth, using precise instruments.

After the decay has been completely removed from the tooth, we will prepare the tooth by etching its surface. Next, we will bond the filling to the tooth, and polish the surface so that the texture is similar to the surface of your natural tooth.

Causes of Decay

Cavities are caused by bacteria in the mouth that consume simple sugars and convert them into acid plaque. The acid plaque builds up on the teeth, and eats away at the enamel and dentin, resulting in cavities.

Plaque can build up on the teeth due to:

• Poor oral hygiene
• A diet high in sugar and acidic foods
• Misaligned teeth

A dental filling will help prevent bacteria from entering the crack or damaged area of the tooth, preventing further infection or decay.
