20 Effective Natural Treatments for Cavities and Tooth Decay

Submitted By Jenny Smith  

Dental cavities are basically small holes in the teeth that develop as a result of tooth decay. Tooth decay is typically caused by lack of dental hygiene or insufficient amount of minerals in the diet that lead to the accumulation of plaque and bacteria in the mouth, thus causing demineralization of the hard tissues of the teeth.

Cavities are also caused by a number of other reasons. These include food particles that remain in your mouth for a long time, improper oral hygiene, taking snacks frequently, dry mouth, eating disorders, and not getting enough amount of fluoride.

But the question is how can you know that tooth decay has set in? Elders can easily observe the changes occurring in their teeth, but it is difficult for children to understand these changes. If you have kids at home, then you should often keep a check on their teeth and make sure to regularly take them to the dentist. Apart from cavities getting prominent in the teeth, the onset of tooth decay is also identified by sticky deposits of dark color that can be found on the teeth, along with the presence of plaque that causes bad breath.

There are various signs and symptoms of cavities depending on the type and intensity of the problem. Some of the most common symptoms include a bad toothache, pain while drinking and eating, prominent holes in the affected tooth, and white, brown or black stains on the surface of the tooth. If not treated on time, cavities can lead to severe teeth problems like infections or tooth loss.

Despite regularly visiting the dentist and taking all precautions, you probably might suffer from tooth decay and cavities at some point or the other in your life. In such a case, you can try out some quick and effective, easy home remedies to prevent dental problems.
