The tiny cracks on your teeth are huge opportunities for bacteria to cause tooth decay.
These cracks, grooves, and pits are collectively known as dental fissures. These occur on the surfaces of your teeth naturally, especially on those at the back. Your molars and premolars are sure to have these fissures. Usually, these are very narrow. This makes them a bit too difficult to clean. And this is the reason why these dental fissures can become such a concern.
Food trapped in these crevices are difficult, if not impossible, to get rid of. As a consequence, they become great causes of tooth decay and other problems like gum disease. Teeth with dental fissures are actually more likely to develop tooth decay compared to other surfaces. As such, dental fissures should be dealt with accordingly.
