Cavities: The Battle Inside Our Mouths

Every day, inside your mouth, there is an epic battle of good versus evil being waged over the ultimate prize: your teeth! And guess what… only YOU can protect them from the destructive forces that seek to harm them.

The Good Guys And The Bad Guys

As tooth enamel is the hardest substance in the human body (it is made up of mostly minerals), we automatically think of it as a tough shield that nothing can get through. In reality, tooth enamel is porous!

When tooth enamel loses minerals, teeth are weakened and more susceptible to decay–we call this demineralisation. If tooth enamel is demineralised enough, a cavity will form. But here’s the good news! The enamel can also be strengthened by receiving nutrients and minerals in a process we call remineralisation. This constant dynamic of tooth enamel losing and gaining minerals is the battle that goes on inside your mouth every day!

So, who are the bad guys? Although there are a lot of good bacteria in our mouths, there’s also the cavity-causing bacteria found in plaque. They feed on sugar and other carbohydrates and produce harmful acids in the process. These acid attacks demineralise or break down tooth enamel, and if left unchecked, can lead to tooth decay.

Check out the video below to learn a little more about plaque.

But all is not lost! You have a secret weapon in your ammunition… and that’s saliva! Not only does saliva wash out food debris and neutralise harmful acids, but minerals in saliva like fluoride, calcium and phosphate can be deposited back into tooth enamel, strengthening and defending it against bad bacteria. That’s why we call saliva the unsung hero of oral health–it works around the clock to protect our smiles and keep our teeth healthy and strong!

Whose Side Are You On?

This “battle” isn’t something that just goes on in your mouth without you having any say in it. You can promote tooth enamel remineralisation and help your saliva fight off harmful bacteria by practising mouth-healthy habits. In the end, you are the ultimate protector of your teeth!

The first thing you can do to defend your teeth from cavity-causing bacteria is to eat a nutritious diet. Sugary drinks and treats, crackers, bread and processed foods are just what these bad bacteria love and eating these types of foods can lead to tooth enamel demineralisation. On the other hand, foods

like cheese, eggs, apples, celery, carrots, dark leafy greens and wild-caught fish promote enamel remineralisation. So the next time you open up the fridge or pantry, make the mouth-healthy choice!

Another way to prevent demineralisation is to brush with fluoride toothpaste. Where plaque breaks down the tooth, fluoride builds it up. This cavity-fighting mineral protects teeth from bacteria by remineralising tooth enamel and reducing plaque bacteria’s ability to even produce acid in the first place.

The third one is to schedule dental check-ups with KIDS. We might run X-rays or tests to know and make sure whether or not there are holes or cavity build up in your mouth that needs to be remedied. Along with the check-up is also a dental cleaning to get rid of plaque formation.
