As annoying and preventable as they are, cavity treatments are one of the most common dental procedures. In fact, according to the Scientific American, around 97 percent of people will run into at least one cavity in their lifetimes. However, some people may be more prone to needing cavity treatments for dental caries than others - even those that are from the same family.
Cavities need four items in a nasty equation in order to thrive: a tooth, bacteria (which will later become plaque), conditions that will let the bacteria thrive and grow and time. However, if you have a few children, you may notice that although they follow the same good hygiene habits, eat the same foods, drink the same liquids and visit the dentist for oral health treatments for kids, one them may need fillings more than the others. Why is this?
Like any other organism, the human body is a complex being, and one of the more multi-diverse parts has to be in your mouth. There has to be a delicate balance of acid demineralization and regular developmental success for the right environment for healthy teeth to grow, as well as proper nutrition. According to the source, a lot of this has to do with pH, which is what causes remineralization to occur. Since everyone's body chemistry is different, some people may have a lack of fluoride ions in their mouths to repair and restore tooth enamel.
There are also several different strains of bacteria that can be more troublesome for some than other. People with deep grooves in their teeth can also create a more significant hotbed for anaerobic bacteria that causes cavities. Salivary flow and diet are also very important factors that you can control, so sticking to a healthy diet and drinking plenty of water can go a long way in the health of your mouth, no matter who you are.
