Dental cavities, also referred to as tooth decay, result from plaque buildup. Plaque is a sticky biofilm that feeds on sugary food particles and releases decay-causing acids that break down tooth enamel. Eroded enamel allows bacteria to enter the tooth and infect dentin and pulp. Review the signs of a potential cavity to help determine if anyone in your family requires timely dental care. 

What Are the Signs of a Potential Cavity? 

1. Tooth Discoloration

Tooth staining can occur for numerous reasons, including drinking beverages with high tannin content like tea and consuming highly pigmented foods, such as beets and berries. However, tooth discoloration can also occur because of cavities. Tooth decay-related stains typically appear as white spots first, then transition into brown, gray, or black spots as the decay worsens. These spots also become larger over time as the bacteria spreads. 

2. Hot and Cold Sensitivities

Enamel not only gives teeth their white color, but it also protects the tooth from hot and cold foods and beverages. Extreme heat and cold irritates tooth nerves, resulting in sensitivity issues that can last seconds to minutes, depending on the severity of the tooth decay. Acidic and sticky foods can also stimulate the nerves, resulting in discomfort. 

3. Bad Breath 

Excess bacteria in the mouth causes bad breath, especially when it accumulates in cavities or gum recession-related pockets. Lingering bad breath that brushing, flossing, and rinsing with mouthwash does not solve can indicate one or multiple cavities. It can also signal a tooth infection that may include an abscess, or pocket of pus. If the abscess drains, it causes both bad breath and a foul taste in the mouth. 

4. Toothache 

As decay worsens and bacteria travels deeper into the tooth, dentin and pulp become inflamed and sensitive. Toothache pain can happen after biting down on food or occur for no apparent reason. It can cause sporadic or continual discomfort until the tooth is professionally cleaned and sealed. Depending on the affected tooth’s location, it is possible to see the hole that plaque has created.
