Dental fillings.

When do you need a filling?

Dental fillings can restore the form and function of a tooth that has suffered decay or minor structural damage, by rebuilding the lost tooth material.

If your existing filling has broken or fallen out, it will need to be replaced to protect the structural integrity of the tooth.

Tooth decay

Tooth decay is the most common reason that both adults and children need a dental filling.

When plaque is not removed from our teeth through daily brushing and flossing, it hardens into tartar and becomes a breeding ground for bacteria. Acid released by the bacteria destroys our teeth's protective enamel layer, leading to a cavity that can cause pain, sensitivity and severe infections.

Before placing a filling, our dentists in West End and Ascot will remove the decayed part of the tooth and clear away the bacteria. The filling then plugs and seals the cavity from further bacterial attack.

Common signs of tooth decay include:

• tooth sensitivity to hot or cold temperatures
• pain when chewing or biting
• visible holes in the tooth surface
• persistent bad breath, caused by the bacteria
• red, swollen gums, caused by gum disease near the affected tooth

And remember, the tartar that harbours the decay-causing bacteria can only be removed professionally by a dentist. The longer tartar stays on teeth, the more decay it can cause. This is why getting regular dental cleans from our Brisbane dentists are so important for preventing tooth decay.

Minor structural damage

Minor structural damage to teeth, including chips, cracks and worn bite surfaces, can also be restored with dental fillings.

In these situations, fillings help stop the damaged teeth from fracturing beyond repair, and also prevent tooth pain and sensitivity by protecting the nerves inside.
