What Causes Tooth Decay?

Tooth decay develops when plaque builds up on the teeth and bacteria produce acids that gradually weaken the tooth structure.

Several factors can increase the risk of tooth decay, including:

  • Inadequate brushing and flossing
  • Frequent sugary foods and drinks
  • Dry mouth
  • Existing dental restorations
  • Irregular dental check-ups

If left untreated, decay can progress deeper into the tooth and eventually affect the nerve, potentially leading to pain, infection and more complex treatment.

The good news is that tooth decay is usually highly treatable, particularly when detected early.

Signs of Tooth Decay

Tooth decay does not always cause symptoms in its early stages.

However, as it progresses, you may notice:

  • Tooth sensitivity to hot, cold or sweet foods and drinks
  • Toothache or discomfort when eating
  • A visible hole or dark spot on a tooth
  • Food becoming trapped between teeth
  • Persistent bad breath
  • Pain when biting or chewing

If you experience any of these symptoms, a dental examination can help identify the cause.

How Is Tooth Decay Treated?

Treatment depends on the extent of the decay.

Options may include:

Tooth Fillings

Small areas of decay can often be treated with a tooth-coloured filling, which restores the damaged part of the tooth.

Crowns

If your tooth is significantly weakened, a dental crown may provide additional strength and protection.

Root Canal Treatment

If decay reaches the nerve inside your tooth, root canal treatment may be needed to save your tooth and eliminate infection.

Preventing Tooth Decay

While tooth decay is common, it is often preventable.

Simple measures such as brushing twice daily, flossing regularly, limiting sugary foods and attending routine dental check-ups can significantly reduce your risk.

Early detection is also important, as small problems are generally easier to treat than advanced decay.
