Worse, such black lines are rather resistant to daily brushing practice and even professional dental cleaning. If so, the black lines are probably signs of dental caries. That means, you have to seek timely treatment instead of leaving it alone. Otherwise, the caries will continue to progress and get deeper.

Moreover, on molars there are originally fits and fissures which are prone to trap food debris and harbor bacteria. As a consequence, molars are more susceptible to tooth cavities.

Following a confirmed diagnosis as cavities, it’s timely filling procedure that should be conducted. It refers to removing the eroding tooth tissues and replacing them with artificial filling material. With extensive clinical applications, filling materials used are proved to be harmless to human body. However, some may start to worry that a filled tooth will be fragile and the fillings may be liable to fall out. Is it true? 

    Indeed, a restorative tooth will perform slightly poorer than a healthy natural one. So it’s not advisable to use it for biting food that are too hard or sticky. If left untreated, however, the cavities will only get larger and make you suffer more. In worst cases you may even require an extraction ultimately.
