ROSELAND, NJ — According to Roseland-based dentist Dr. RoseAnn Giannella, a common question she receives from parents is whether DNA can predetermine dental health.

In response, Giannella recently shared which oral issues parents could be passing down and what they can do about them.

“It’s the classic nature vs. nurture question that dentists get asked often, but the answer doesn't simply boil down to one or the other,” she said. “The scary truth is that many dental problems are indeed ‘inherited,’ but not from genetics alone. Harmful habits that run in the family can also play a huge role in the health of your child's smile.”

Even before birth, Giannella said the stage has already been set for certain aspects of a child's oral health. She said that ultimately, the child's genes dictate the likelihood for common issues such as:

Jaw-related Disorders: The size and position of one's jaws, as well as overall facial structure, are hereditary traits that can cause a number of bite complications (or "malocclusions"). Overbites or underbites caused by uneven jaws can lead to chewing and speech difficulties, and result in chronic pain and/or Temporomandibular Jaw Disorder ("TMJ") if left untreated.

Tooth Misalignments: Spacing problems, either due to missing or overcrowded teeth, are oral issues that have been hardwired in a person even before the emergence of teeth. Cases where people lack some ("Anodontia") or all ("Hypodontia") permanent teeth can threaten gum and jaw health, as can instances of "supernumerary" teeth, in which extra teeth erupt.

Weak Tooth Enamel: Though rare, it is possible for tooth enamel to be defective, or develop abnormally. Dentin, which makes up the protective enamel covering of teeth, may not be produced or mineralize at normal levels, leaving teeth vulnerable to decay, sensitivity and damage.

Predisposition To Oral Cancer: Genetic mutations and the presence of oncogenes, a type of gene that transforms healthy cells into cancerous ones, can increase the risk for cancer by interfering with the body's ability to metabolize certain carcinogens.

“From serious conditions such as a cleft palate, to occasional aggravations like canker sores, many other oral issues may be linked to genetics,” said Giannella. “Keeping track and sharing the family's health history with your child's dentist can help detect and treat inherited conditions as early as possible.”

Behavioral Risks

According to Giannella, DNA may deal a child some unavoidable complications. However, when it comes to tooth decay and gum disease, Giannella said learned habits and tendencies shoulder much more of the blame, including:

"Oversharing": Harmful oral bacteria from a loved one can easily colonize and overtake your little one's mouth from something as simple as sharing food, utensils, or kissing. The inadvertent swapping of saliva can put your child at increased risk for cavities and gingivitis.

Diet Choices: Satisfying that sweet tooth with sugary, refined treats, or turning to soda and juice for refreshment can create an unhealthy addiction that's as dangerous to the mouth as it is to the waist. Sugar and acid can eat away at the tooth enamel, causing cavities and tooth sensitivity. Exposure to certain chemicals and ingredients can also cause discoloration.

Bad Hygiene: Last, but certainly not least, lacking a good dental routine can wreak havoc on teeth and gums. Failing to follow through on brushing and flossing twice a day (or as recommended by the dentist) can create a haven for cavities and periodontitis, not to mention halitosis.

“Leading by example is an easy, effective way to teach your child the importance of oral health while benefitting the whole family,” said Giannella. Every parent wants the best for his or her child–including a healthy smile. With so many potential problems that can be passed down, protecting your child's oral health is not easy, but you don't have to do it alone.”

Giannella encouraged parents to seek the help of their child's dentist for optimal professional and at-home dental care. She said treating existing issues early on and teaching children to make dental-friendly decisions can provide lifelong benefits to their health.
