Read this blog to Understand Dental Cavities & Its Causes, Have you ever wondered how a dentist can tell that you have dental cavities? The best way is to look at an x-ray, which clearly shows how tooth decay is impacting the enamel of the tooth. The dentist also uses an instrument if a spot feels soft instead of solid, that’s a good indication of tooth decay.
And sometimes, the dental decay is so severe; you can see it with the naked eye. It may begin as a white spot, and then darken into a brown-colored stain. As the decay worsens, it creates a hole in the tooth.
What Causes Dental Cavities?
Millions of bacteria live in your mouth. Most of these are beneficial; they produce acids that help break down food. Other types of bacteria produce acids that break down the enamel of your teeth. These bacteria attach to your teeth to form a sticky layer called plaque. If the plaque is not removed by brushing and flossing, the acid from the bacteria starts to wear away the enamel.
While proper brushing removes cavity-causing plaque from the tops and sides of your teeth, it does not remove the plaque from between your teeth. Only flossing can remove the particles of food and bacteria caught between teeth. That’s why it’s so important to floss at least once a day.
Fluoride is another important tool in the fight against tooth decay. Ask your dentist about fluoride therapy. And last but not least, make sure you’re keeping up with your professional teeth cleanings. Only a dental professional can remove the plaque and tartar build-up from all those hard-to-reach places in your mouth.
Dental filling procedure
When filling a tooth, the dentist begins by administering a local anesthetic to numb the area around the tooth to reduce any pain. The dentist will isolate the tooth to prevent contamination and keep it dry by using some kind of guard and then remove the decayed area of the tooth with a tool designed specifically for both the severity of the cavity and its location in your mouth.
Once the decay has been removed, the dentist will prepare the tooth for the filling by thoroughly cleaning it so you won’t have any bacteria, decay, or debris causing future problems. The dentist will apply the filling material, which may require a special light to cure or harden the product. In the final step of the dental fillings procedure, the dentist will test your bite to ensure proper alignment and then polish so the filling is as smooth as your other teeth.
