However, it can be prevented. Tooth decay is caused by several reasons. So looking for signs and symptoms can help to treat the condition as early as possible.

What is tooth decay?

Tooth decay is caused when plaque, sticky, film-like bacteria, combines with starches and sugars of the food eat, it produces an acid that attacks tooth enamel. When the tooth enamel is eroded, the bacteria will seep through the teeth, infect the dentin, and finally affect the root. Plaque can eventually eat away the sensitive enamel, making it more vulnerable to tooth decay.

Common Signs and Symptoms

Dental decay can be detected through routine Blacktown dental exams. Only in a few cases, a dental x-ray is needed to spot the signs and detect the dental decay. Cavities can form on all sides and found at the back teeth as it can be challenging to keep them clean.

The following are the most common signs of dental decay, and if you experience any of the signs, visit the Blacktown dentists.

Dark spots

When dental decay begins to develop, you can notice dark spots on the tooth’s surface. Initially, these spots may look like a stain on your teeth, and you may assume that it’s tooth discolouration. Over time, the dark spots can get bigger that signify dental decay. In some cases, it can even look like light marks or white spots on the tooth.

Tooth sensitivity

When the decay continues to infiltrate the tooth, the dentin becomes exposed, which leads to tooth sensitivity. When you have something cold or hot, you may notice a surge of pain specific to one or more teeth. This is a tell-tale sign that indicates you have cavities.

Holes on teeth

The bacteria present in the tooth due to dental decay can eventually eat out the tooth completely and cause small holes in the enamel. If you see any holes or pits in your mouth, visit the dentist.


The cavity can cause severe pain, and you will find it difficult to bite down without sharp and shocking pain. This is caused when the dentin is exposed and affecting the nerve of a tooth.
