Decay occurs for several reasons:
- Decay occurs when a tooth becomes compromised as a result of contact with acids. Acids are the byproduct of bacteria in your mouth breaking down the sugar in your food. With this in mind, the more foods you eat containing high levels of sugar, the more prone you will be to acid attacks in your mouth and, consequently, decay.
- A poor oral hygiene routine can lead to and exacerbate tooth decay by weakening your tooth enamel.
- Overlapping fillings and other restorative work such as bridges, dentures and crowns can result in food particles lingering and blocking your toothbrush and floss’s route to the area.
