Dentistry has come a long way, but there are still discoveries to be made in the field. Case in point, it was previously thought that the bacterial species Streptococcus mutans was the main culprit behind tooth decay – but recent research indicates that another kind of bacteria may also be a major contributor. Your preventive dentist wants you to be as informed as possible when it comes to your oral health, so here is a quick look at this bacteria and how it can be linked to cavities.
What Have Researchers Found?
A study published by the University of Pennsylvania took a look at the plaque samples from 300 children in the age range of 3 to 5 years old. Note that half of the children in this study had cavities. After examining these samples, researchers found that a kind of bacteria called Selenomonas sputigena is involved in the tooth decay process.
Previously, it was believed that S. sputigena only played a role in gum disease. However, while it can’t cause cavities on its own, it can potentially make tooth decay worse thanks to its interactions with S. mutans. Simply put, S. mutans can produce sticky glutans that S. sputigena can get trapped in. In response, S. sputigena can grow and create a superstructure that keeps S. mutans safe. The result of this relationship is that S. mutans ends up producing more acid, thus making tooth decay even worse.
It’s worth mentioning that it’s currently unclear how S. sputigena is transferred to the teeth to begin with. Further research is needed to investigate this point.
What Can You Do to Protect Your Smile from Tooth Decay?
If you want to keep your teeth safe from cavity-causing bacteria, you need to take the initiative in caring for your smile. Here are some tips for minimizing the risk of tooth decay:
- Stay away from sugary foods and beverages. The bacteria in your mouth can feed off of sugar and turn it into an acid that can gradually break down your enamel. Try swapping out sugary treats with fruits, vegetables, and other foods that are good for oral health.
- Brush your teeth at least twice a day to prevent the accumulation of plaque. Each brushing session should last at least two minutes. Make sure that you’re cleaning your entire smile as thoroughly as possible.
- Pay your dentist a visit at least twice a year. They can clean the parts of your smile that you’ve been having trouble reaching on your own.
Being aware of threats to your oral health and how you can protect yourself from them is essential. Be sure to consult your dentist if you have any questions about the harmful bacteria in your mouth.
