Tooth Decay (Dental Caries) - Causes, Stages and Treatment
Cavities start small but can lead to sensitivity, pain and infection if ignored. This guide explains how decay develops, what symptoms to watch for, and how we provide gentle cavity treatment for patients near Kangaroo Point and East Brisbane.
What is tooth decay
Tooth decay - also called dental caries - happens when bacteria in plaque turn sugars into acids that dissolve tooth minerals. Early decay can often be reversed with fluoride and diet changes. Deeper decay usually needs treatment to stop sensitivity, pain and infection.
Early stage - white spots
Minerals leach from enamel leaving matte white patches. Often no pain. This stage can be remineralised with fluoride and diet changes.
Cavity in enamel or dentine
When acid breaks through enamel into dentine, food traps and sensitivity can appear. We restore comfortably with tooth-coloured dental fillings.
Pulp involvement
Deep decay can inflame the nerve, causing lingering pain. Treatment may involve root canal treatment or a protective dental crown.
Common signs
- Sensitivity to cold, heat or sweets
- Food catching between teeth
- Visible brown or black spots
- Bad breath or an unpleasant taste
Who is at higher risk
- Frequent snacking on sugary or acidic foods or drinks
- Not brushing and flossing daily
- Dry mouth - medications or mouth-breathing
- Braces, dentures or deep grooves that trap plaque
- Children and teens with erupting molars
How to prevent cavities - and stop early ones
Daily home care
Brush twice daily with fluoride toothpaste and floss once a day. Spit - do not rinse - so fluoride stays on your teeth.
Smart diet
Keep sugary foods to mealtimes and swap sticky snacks for cheese, nuts or vegetables. Limit acidic drinks between meals.
In-clinic prevention
Topical fluoride and tailored advice. Deep grooves can be protected with fissure sealants - ideal for kids and teens. Learn more via kids dental care.
Gentle, modern cavity treatment options
Tooth-coloured fillings
Tooth-coloured fillings blend with your natural teeth and seal out bacteria. We remove only the softened tooth and keep as much healthy enamel as possible.
Root canal treatment
If decay reaches the nerve, root canal treatment can relieve pain and help save the tooth. A crown may be recommended for strength on back teeth.
Same-day emergency care
Severe toothache, swelling, or a broken tooth can escalate quickly. Same-day help is available when needed.

Tooth Decay (Dental Caries) - Treatment and Prevention in Brisbane
If you are searching for tooth decay treatment in Brisbane or want to understand dental caries, the most important step is to treat cavities early - before they reach the nerve. At EasyCare Family Dental, a trusted dentist in East Brisbane, we assess the stage of decay and explain the most conservative way to stop it.
In the early stages, prevention and stabilisation usually start with a thorough exam and professional dental cleaning as part of general dentistry. When a cavity has formed, treatment often involves dental fillings. If a tooth is heavily weakened, a dental crown may be needed to protect it from cracking. If decay reaches the nerve and you develop lingering pain or swelling, a root canal treatment may be required to save the tooth. If symptoms flare up suddenly, see our emergency dental page for urgent care guidance.
For children and families, early prevention matters - especially if you are noticing frequent cavities or high sugar exposure.
