What is a Tooth Cavity? | Dental Clinic in Canberra

What is a Tooth Cavity?

A cavity is an opening or hole in a tooth where it has begun to decay, and which allows infection-causing bacteria to enter the tooth. Tooth decay is usually caused by a combination of factors including poor oral hygiene, snacking frequently, or consuming too many sugary or acidic drinks. Tooth decay is unfortunately very common and can affect young children, teenagers and adults. Unless a cavity is treated promptly, it will continue to become larger, eventually infecting the tooth nerve and can even result in tooth loss.

What are the Symptoms of Tooth Decay?

Initially, you may not have any symptoms until the cavity becomes larger. Possible symptoms include:

  • Toothache or pain after consuming hot, cold, sweet or sour foods
  • Visible holes in a tooth
  • White, brown or black stains on a tooth surface
  • Tooth sensitivity
  • Pain when biting or chewing food

Avoiding Tooth Decay Problems

Regular toothbrushing and flossing, combined with dental checkups and hygiene treatments, are an effective way to maintain strong and healthy teeth. When you visit Oasis Dental for your dental examination, we carefully assess every tooth for tiny lesions or cavities. Early treatment is more effective at saving and preserving the tooth and prevents unwanted symptoms. We can also assess your risk of tooth decay and will devise a suitable preventative plan if needed. For example, in some cases we might recommend fissure seals to seal off tiny hard-to-clean areas of the tooth to prevent bacterial infection and thus tooth decay.
