There are a great number of people that do not undergo regular dental check ups. These people do not recognize the importance of keeping a healthy mouth. This is because diseases of the mouth, such as gum diseases have been researched thoroughly and shown correlation with an increase in developing heart diseases and high blood sugar. Keep in mind that even the smallest of cavity can lead to dental caries which could hurt when infected.
Unfortunately, a large portion of the population still suffers from untreated and undetected infections in the mouth, unaware that this overlooked oral condition can be a red flag for other serious diseases. No need to fret, however, so long as you have a trusted dentist beside you.
