Why people who don’t take care of their teeth, don't get cavities?

Some people who don't brush and floss don't get cavities because they are lucky enough not to have the bacteria that cause cavities such as streptococcus mutans. They may also have cavity inhibiting bacteria and have positive factors such as strong enamel and lack deep pits and grooves in their teeth. Their diet may be low in carbohydrates and sugars that are needed for cavity formation. Why flossing is important, why brushing is important, importance of brushing and flossing, cavities despite brushing and flossing, cavities and plaque, cavities from not flossing.

Have you ever wondered why some people who don’t take care of their teeth don’t get cavities? Sometimes I have a patient and when I tell them they have a cavity they point to their brother or sister sitting in the chair next to them and exclaim “He or She doesn’t ever brush their teeth but I get the cavities, Life is not fair.!” Well, there are reasons for this. One of them is that the plaque that is being brushed off partially consists of little microscopic bugs called bacteria. Some bacteria cause cavities, but many others do not. Interestingly enough there is at least one type of bacteria they may help prevent cavities . It gets tricky because it is probably not known what all of the bacteria that cause cavities are. This is because there are at least hundreds of different bacteria and other micro-organisms that inhabit the oral cavity. Unfortunately, most of these are difficult to grow outside the mouth on let’s say a petri dish. This means that scientist can’t study them and figure out what they eat, what they produce or what they do. How do we know there are a lot of bacteria that live in the mouth? It’s from something called PCR or polymerase chain reaction. PCR is basically a laboratory procedure that isolates small mounts of different DNA. It’s from their DNA that we know there are so many. If you going to get cavities, you have to have the bacteria in the mouth that causes them. What are some of the bacteria that a known to promote cavities? The main one is called streptococcus mutans , yep, the same family of bacteria that causes strep throat along with a lot of other infections. Another one is Lactobacilli. Let’s focus on S. mutans, an abbreviation for streptococcus mutans. How does S. mutans cause cavities? This is the simplified explanation. They eat the sugars that you eat. From those sugars they produce acid, the acid dissolves the first layer of the tooth called enamel, once it has dissolved the tooth through the first layer and get to the second layer, a hole is created that’s technically called a cavitated lesion or commonly referred to as a cavity. By brushing and flossing you are mechanically removing both the bacteria and the food they eat from the tooth surface. The less bacteria and the less food for them to eat equals less cavities overall. Why do people who take really good care of their teeth still get cavities? There are other factors, such as the strength of the enamel, amount of pits grooves in the teeth and the micro structure of the enamel, along with amount of saliva and other factors. You can’t remove all of the bacteria and for those who still get cavities, there is enough left to cause problems is the short answer. Why do some people who don’t brush and floss but yet don’t seem to get cavities? They may just not have enough s. mutans and other cavity promoting bacteria in their mouth to make a difference. Or maybe they have enough cavity inhibiting bacteria to counteract the S. mutans. Should they continue to ignore oral hygiene? Probably not. As mentioned, there are lot of bacteria in the mouth that don’t cause cavities and some of these do cause inflammation of the gums called gingivitis, inflammation of the bone called periodontitis. Periodontitis can lead to periodontal disease, bone loss around your teeth and eventual tooth loosening or loss. (show photo of dirty teeth with gingivitis). One can see the inflamed gum tissue in this photo again Consider yourself lucky if you don’t have cavities, but still take good care of your teeth. You will likely be glad you did, besides that, who wants dirty teeth or bad breath? You want to look like this
