What Causes Teeth to Wear Out Early: Erosion
Posted: 12 Nov 2011 03:20 PM PST
There are four major ways that we wear down our teeth, but perhaps the most common cause is because of erosion. With abrasion and attrition, the depletion of enamel occurs through some sort of grinding and the difference between them is marked by what exactly is doing the grinding. Erosion works in an entirely different way. Erosion is caused by acids depleting the enamel, such as the acids in foods and beverages or the acids that plaque can leave behind. There are actually several different ways that acid can erode our teeth.
The first and most common cause of erosion is due to plaque. We have blogged here about plaque a lot before, but to give the basic overview plaque is caused by bacteria. Bacteria that occur naturally in our mouths feed on the foods we eat, mostly the sugars, and leave behind plaque. Plaque then erodes our teeth. The best way to prevent this type of erosion is to be careful about the different foods you eat. Eating less sugary foods is very important, as well as eating only certain kinds of sugar. Processed sugars leave behind more plaque than natural sugars. So eating a piece of candy is going to be worse for your teeth than eating a piece of fruit as far as plaque goes. Another very important step to reducing plaque is to always brush and floss your teeth. After the bacteria have left behind their plaque it is important to remove the plaque as quickly as possible, by brushing and flossing. And of course it is always import to see a dentist on a regular basis to professionally clean your teeth. It is generally recommended that everyone see a dentist at least once a year for a regular cleaning.
The second most common means of erosion also has to do with our choice of food, which is because some foods are more acidic than others. Regardless of the sugar content causing plaque, some foods have their own erosive factors that can cause wearing of enamel in addition to causing plaque. Drinks like sodas are high in acid content as we all know, and can often cause some very problematic erosion. Something that is not often known however is how foods like apples also contain a high acid content and will erode the enamel. Generally we think of apples as a very healthy food to eat, and they are, but you should be careful about eating them because of the high acid content. There are many different types of acids that can erode the teeth and they are found in most of the foods we eat. This doesn’t mean that we should avoid acidic foods altogether. Human saliva has a special agent in it that helps our teeth to re-mineralize after consuming acid. But we should always be careful to consume acidic foods in moderation.
The last and least common way that teeth get eroded happens when we get sick. Stomach acid is, of course, acidic. When vomiting, the stomach acid washes over our teeth and causes them to erode. This is usually the least common cause of erosion for people since most of us don’t get sick too often. However, patients who suffer from gastroesophageal reflux disease, or more often known as acid reflux, can easily have this cause of erosion skyrocket to the top spot. Those who suffer from acid reflux will have a very acidic oral environment, and should be careful about maintaining their oral health. When someone is often sick, their mouth becomes very acidic as well. Regular dental appointments with your dentist are the best way to keep the damaging effects of acid reflux on the teeth under control.
This is just one of the four major ways that teeth are eroded. The other three are abrasion, attrition, and abfraction. If you are concerned that you may be wearing down your teeth through any of these, you should see your dentist right away. Don’t wait to get your teeth checked out because the longer you wait the more severe the damage is likely to be.

Obesity Link To Periodontitis
Obesity Link To Periodontitis
02 Nov 2011In a study titled "MicroRNA Modulation in Obesity and Periodontitis," lead author Romina Perri, University of North Carolina School of Dentistry, Oral Health Institute, conducted a pilot investigation to determine whether obesity or periodontal disease modified microRNA expression and whether there was any potential interaction between obesity and periodontitis that could involve microRNA modulation. This study is published in the Journal of Dental Research, the official publication of the International and American Associations for Dental Research (IADR/AADR).
In this investigation, total RNA was extracted from gingival biopsy samples collected from 20 patients in 4 groups (5 non-obese [BMI < 30kg/m2] participants with a healthy periodontium, 5 non-obese participants with periodontitis, 5 obese [BMI > 30kg/m2] participants with a healthy periodontium and 5 obese participants with periodontitis).
Two microRNA species (miR-18a,miR-30e) were up-regulated among obese individuals with a healthy periodontium. Two microRNA species (miR-30e,miR-106b) were up-regulated in non-obese subjects with periodontal disease and in the presence of periodontal disease and obesity, nine microRNAs were significantly up-regulated (miR-15a,miR-18a,miR-22,miR-30d,miR-30e,miR-103,miR-106b, miR-130a,miR-142-3p,miR-185 and miR-210). The authors conclude that the data are consistent with the concept that miRNA that are induced by chronic nutritional stress leading to obesity may also non-parsimoniously modulate inflammatory pathways within periodontal tissues and affect disease expression.
"The expression of specific microRNA species in obesity provides new insight into possible mechanisms of how risk factors might modify periodontal inflammation and may represent novel therapeutic targets," said JDR Editor-in-Chief William Giannobile.
A perspective article titled "Obesity, Inflammation and Oral Infections: are microRNAs the Missing Link?" was co-authored by Francesco D'Aiuto and Jean Suvan, University College London Eastman Dental Institute. In it, the authors suggest that these data could represent a mechanistic breakthrough in our understanding of the modulatory effects of obesity on periodontal tissue destruction, but caution reproducibility of these findings is needed in larger and well-characterized cohorts.
