Tooth Decay -Genetic or Environmental?

September 4th, 2019

It’s easy to blame somethings on our parents, but recent research shows that you shouldn’t blame tooth decay on genetics. In the past it has been thought that our risk of developing cavities is similar to our family members. However, more research is showing that tooth decay boils down mainly to environmental factors rather than genetics. Although we can’t just easily point to our parents when we develop a cavity, this can be a good thing because tooth decay is largely preventable! Take a look at what influences your risk of tooth decay and how you can prevent it:

Interestingly enough, we are made up of good bacteria that help us survive. However, some of the bacteria found within the mouth can feed on sugars within the foods we eat and lead to tooth decay. These bacteria produce acids that wear down our tooth enamel and create what we all dread and know to be cavities. These bacteria often come after birth, and with more research specific bacteria are being found to play a role in creating cavities. While some bacteria we do inherit from our parents, others that have been linked to causing dental cavities are not found to be associated with genetics, including Streptococcus mutants, and Porphyromonas gingivalis. The study conducted by the J. Craig Venter Institute in Maryland evaluated 485 pairs of identical and fraternal twins within the age range of 5 to 11 years old. When analyzing the study participants’ dental plaque and bacteria present within the mouth, they found that environmental factors played a significant role in the type of bacteria present that were associated with causing tooth decay. The bacteria responsible for causing tooth decay were mainly due to factors including diet and home care dental habits such as brushing and flossing. However, family history is important when looking at risks of tooth decay, for instance similar food diets shared between family members could increase or lower the risk of tooth decay.

What you may be able to blame genes for is the development of teeth. Such as the relationship between your teeth when biting together, the timing in which your teeth first appear, or even the size of teeth (macrodontia or microdontia).

So, while somethings you may get away with being able to blame your parents for, tooth decay is largely in part influenced by environmental factors. This is why it’s extremely important to get regular dental check-ups, and practice good oral hygiene care to ensure that your teeth are healthy and lasting lifetime!

Abnormal Tooth Enamel: Amelogenesis Imperfecta

March 17th, 2016

 enamelAmelogenesis imperfecta is an inherited disorder in which tooth enamel forms abnormally. As a result, individuals with this condition are at a higher risk of developing cavities. It typically causes teeth to be smaller than usual, discolored, grooved, easily damaged, among other dental problems that can vary by the individual. Secondary effects could be early tooth loss, periodontal disease, tooth sensitivity, and jaw problems.

Unfortunately, Amelogenesis imperfecta can negatively impact both primary teeth and permanent teeth. Around 14 forms of this condition have been determined by researchers. It has also been found to affect approximately 1 in 700 people in northern Sweden to 1 in 14,000 people in the United States.

Many cases of Amelogenesis imperfecta are a result of mutations in the AMELX, ENAM, MMP20, and FAM83H genes, which are normally responsible for making proteins essential for normal tooth and enamel development (ameloblastin, enamelin, tuftelin and amelogenin). Tooth enamel is a hard outer layer rich in calcium that functions to protect the tooth. As a result of a mutation, tooth enamel becomes thin and weaker than normal, and may even appear yellow or brown in color. The genetic causes of other cases have not yet been identified.

This condition can be inherited in both an autosomal dominant pattern and autosomal recessive pattern. In an autosomal dominant pattern, once copy of the mutated gene in each cell can cause Amelogenesis imperfecta. An autosomal recessive pattern involves two mutated copies of the gene in each cell. Researchers found that around 5 percent of amelogenesis imperfecta cases are due to mutations in the AMELX gene and are inherited in an X-linked pattern. They also found that males with X-linked amelogenesis imperfecta have more severe dental problems than females with this form of the condition.

Preventive and restorative dental treatments can help make teeth impacted by this condition look normal and remain healthy. Full crown restorations are often used to treat this disorder. For severe cases, teeth may have to be extracted and implants or dentures may be required. If you feel like you have Amelogenesis imperfecta or any other enamel conditions, our very Dr. Ejaz Ali is an expert at fixing the issue, bringing the teeth back to ideal form, function, and esthetic. Dr. Ali was trained at Tufts School of Dental Medicine, and also did additional training at New York University’s in “Full Mouth Reconstruction: Advanced Principles and Practice for the GP” with special focus on Implants, Aesthetics, and Occlusion.
