Operative dentistry, commonly known as fillings, it’s a branch of dental and oral treatment to keep the teeth in working condition with the same shape as or close to the original tooth. Sometimes fillings are used to correct the original teeth for a better or more beautiful appearance. After filling the teeth, you can chew food as well. The nature of the filling depends on the condition of the tooth decay. The dentist will diagnose and fill the teeth to prevent the spread of symptoms that may extend to the root canal. If it is not corrected promptly, it will eventually be necessary to extract the tooth.
