While some people blame their teeth for being more prone to cavities on genes, there usually remain other reasons for this tooth problem. Following are some of the factors that make you more likely to get cavities:
If you have had cavities in the past, it makes sense why you are more likely to keep getting cavities until you make some changes for good.
FREQUENT SUGAR CONSUMPTION:
Sugar provides a great source of fermented carbohydrates to the bacteria, something they love and live for. Frequent sugar consumption results in these bacteria producing surplus of cavity-causing acid that will eventually erode away the teeth.
BAD FILLINGS AND/OR CROWNS:
Poorly crowned or filled teeth facilitate the buildup of plaque and bacteria where you cannot reach during the brushing and flossing routine.
Lack of saliva production in the mouth leads to it becoming dry, and this condition is medically known as xerostomia. A dry mouth encourages the buildup of bacteria and plaque, since food debris and acid are not properly washed away due to less saliva. These bacteria then feed on the food bits and sugars, converting them into acid plaque that leads to cavities.
RADIATION TREATMENT AND CHEMOTHERAPY:
Radiation treatment or chemotherapy in the neck or head area can decrease the salivary flow, leading to oral problems that amplify the risk of getting cavities.
Although braces play a major role in straightening and beautifying your teeth, they can also simultaneously make them more prone to cavities. This is because braces make brushing harder and flossing nearly impossible. This improper oral hygiene routine eventually gives way to cavities.
EXPOSED ROOT SURFACES:
The root of the teeth gets exposed in case of receding gums, where the protective enamel coverage is absent. This leads to the dentin (which makes up the roots) dissolving at a higher PH in contrast to the enamel, which means that weak acids will eat away the roots and make the teeth more vulnerable to cavities.
These are some of the reasons why you may have a higher risk of cavities.
