Whether or not dental cleaning can remove bad breath depends largely on the cause of the bad breath. If the bad breath is caused by an oral disease, it can be removed. If the bad breath is caused by gastric diseases, it is difficult to remove the bad breath by simply cleaning the teeth.
1. Oral disease: If the bad breath is caused by gingivitis, periodontitis and other oral diseases, it can usually be removed by scaling. This is because dental scaling can remove the plaque and calculus attached to the teeth, which can prevent the occurrence of oral diseases such as gingivitis and periodontitis, and ultimately achieve the purpose of removing bad breath.
2. Stomach diseases: If you suffer from chronic gastritis, gastric ulcer and other stomach diseases, infected with Helicobacter pylori, then Helicobacter pylori secretes urease enzyme decomposition into carbon dioxide and ammonia, which will cause bad breath, which can not be removed by simply scaling the teeth and need active treatment to kill Helicobacter pylori, which may improve or alleviate the symptoms of bad breath.
Therefore, teeth cleaning does not necessarily remove bad breath. If you have a problem with bad breath, it is recommended that you go to a regular hospital as soon as possible for a consultation and examination to clarify the cause before considering whether to have your teeth cleaned.
