Dental decay is one of the most common dental problems that affect millions of Australians. However, dental decay is a preventable dental disease. Yes, in most cases, poor dental hygiene and unhealthy eating habits are the significant reasons for tooth decay. If left untreated, tooth decay has an impact on the overall health and structure of the teeth. Dental decay is caused by various reasons. So, looking for signs and symptoms can help you prevent the infection from spreading further, damaging the nerves and leading to tooth loss.

What Is Tooth Decay?

Tooth decay, also called dental decay, occurs when the enamel, outer layer of a tooth, is eroded by bacteria that has infected the inner dentin. Plaque, a thin film-like bacteria, is the major reason for enamel erosion and formation of cavities. Plaque is formed from the food particles stuck between teeth. The sugary and starchy substance present in the mouth combines with the plaque and produces acid that attacks and eat away the tooth’s enamel. When the tooth’s enamel is eroded, it exposes the tooth root and becomes more prone to decay. When caught early, the dentist Epping will remove the decayed part and fill the tooth.

Common Signs and Symptoms of Dental Decay

Discolouration and Dark Spots

When a cavity begins to develop, dark spots tend to appear on tooth’s surface and it’s visibly noticeable. This is one of the significant signs that you need to look for if you suspect that your teeth are decaying. Initially, it might seem like spots that have mild tooth discolouration. Over time, the dark spots can become bright, signalling tooth decay.

Sensitivity to Cold and Hot

When the decay continues to damage the tooth, the dentin will be exposed. At this stage, dentin becomes more porous and can cause sensitivity. If you notice a sharp pain when taking a hot or cold drink or food, it’s a sign indicating cavities.


Holes in your tooth is an obvious sign indicating tooth decay. It’s more of an advanced stage as the bacteria have eaten away most of the tooth, exposing dentin and root of a tooth. In such condition, the tooth might need filling. The decay will be removed, and a new filling will fill in the hole that’s currently visible. The best dentist in Epping will remove the decay and fill the tooth to prevent further infection from spreading to surrounding teeth.


A decayed tooth can cause pain, and you might find it difficult to bite down without sharp, shocking pain. This is caused because the dentin and inner nerve of a tooth are exposed. If you experience unbearable pain, please call the dental clinic Epping and fix an appointment with the dentist. The dentist will suggest you the right treatment plan to treat your cavities.

If you notice any of these signs, please visit your dentist as early as possible so that you can avoid tooth loss and root canal procedures.
