Is Salt Bad For Your Teeth?

Salt is the main ingredient in many foods that are considered bad for your teeth, but the different kinds of manifestations of sodium are also the main ingredient in most toothpaste so it is very hard to discern if salt is bad for your teeth. The relationship between sodium and your oral fauna is a complex one.

Possible benefits of salt

The fauna and flora of your mouth and intestines both like and dislike salt. As a substance, salt is antibacterial, and as a substance it does not damage your tooth enamel at all. In fact, using a salt water rinse can help kill bacteria in hard to reach places. But the gums and soft tissues do not like salt at all.

Problems from sodium

The main problem with just salt, and not with salty foods, is that it creates a hostile oral environment. It dries out the mucous membranes, which play an important part in lubricating the soft tissues and gingiva, and keep teeth healthy by maintaining a healthy oral environment. With salt, the liquid is taken out of the soft tissues, and this creates a dried out oral environment. This is no problem if you drink plenty of water, as this will re-lubricate the area, and the immediate effects of slat will be neutralised. But hypertension will have an effect on teeth as well, as this condition affects the entire immune system. Some problems that may be caused by a diet that is too high in sodium:

-    Gum recession can be caused by the eating too much salt, and the gums, a part of the immune system, may pull back to reveal the cementum of the teeth, making them more vulnerable and less resistant to tooth decay.

-    Xerostomia, or chronic dryness of the mouth, can also be caused by eating too much salt. This is a problem, as xerostomia can lead to gum disease, a heightened risk of tooth decay, halitosis and problems of the tongue.

-    More frequent bleeding of the gums can occur when the oral environment is dry. This kind of bleeding usually occurs when eating food or brushing teeth, as the dried out gums are frailer, and will induce more frequent extra capillary action.
