The Science of Tooth Decay
If you’ve visited our blog before, you know that we love to talk about tooth decay. The chances are, everyone has had or will have tooth decay at one point. It is classified by the National Institutes of Health as the most prevalent disease in the world. Today we’re going to talk about a few of the factors involved in causing tooth decay and what you and Portland dentist Dr. David Case can do to protect your smile.
The Unique Makeup of Your Teeth
Even within your own mouth, teeth vary widely in shape, size, and enamel quality and consistency. Some teeth are harder than others, and some—especially molars—may have deep fissures that can trap bacteria, causing decay. Additional defects in enamel formation can cause yellow or brown areas on your teeth that are more susceptible to caries (tooth decay).
The pH Level in Your Mouth
Research indicates that acidity in your mouth plays an important role in developing tooth decay. A low pH (an acidic state) allows decay-causing bacteria to thrive. Acidity is affected by the quality and flow of saliva, diet, and a number of other factors. For example, after eating carbohydrates, people will experience a temporary drop in the pH of their saliva.
Diet
One of the biggest and most easily controlled risk factors for tooth decay is diet. An unhealthy diet rich in sugars and sticky foods will increase the amount of plaque formed and lower the acidity of your saliva.
