Are you cavity prone?

It’s common knowledge that brushing your teeth, flossing, and regular dental hygienist visits will help stop cavities. However, despite their best efforts, many people are just more prone to cavities.

The Cause of Cavities

In actuality, there is no scientific proof to support the claim that regular brushing and flossing will completely prevent cavities. But we can attribute tooth decay to two primary things: sugar and genetics.


The truth is that cavities can’t exist without sugar. Bacteria in the mouth survive on sucrose, which is the chief component of sugar. Bacteria multiplies and thrives between our teeth, causing decay in the process. If you have existing holes, cracks, or crevices in your teeth, you are more likely to experience decay as well. This brings us to our second cavity cause and the answer to our question: Are you prone to cavities?


Certain people have naturally deep crevices in their teeth, which creates a more comfortable space for bacteria to expand into the tooth and create a cavity. We can address deeper crevices by applying a sealant to the grooves of your teeth. 

You may also be more prone to cavities if you don’t produce as much saliva. Saliva contains, bicarbonate, and phosphate, which helps to repair early tooth decay and neutralize the acid that creates plaque. Certain medications can also cause your saliva production to decrease. Smoking, stress, ageing, autoimmune disorders, and chemotherapy can lead to dry mouth as well. Your doctor can advise ways to increase your production of saliva if drinking more water throughout the day does not help.

How Can I Prevent Cavities?

Although daily brushing and flossing are not proven to prevent cavities completely, using toothpaste that contains fluoride can decrease them by up to twenty per cent. Reducing your consumption of sugar and carbohydrates, which convert into sugar in the mouth, will also significantly reduce your chances of getting cavities. If you already have decay, Dr Serfontein can repair your cavities with dental bonding.
