13 Awful Things That Happen If You Don’t Brush And Floss Your Teeth

Dentist teeth


Can’t ever find the time to take care of your teeth? About half of Americans don’t floss daily, and one in five don’t brush twice daily — so you’re not alone.

But you may want to reconsider.

“Taking care of your teeth and gums isn’t just about preventing cavities or bad breath,” the American Dental Association warns. “The mouth is a gateway into your body’s overall health.”

It’s almost impossible to prove a cause-effect relationship between dental neglect and various conditions because researchers would have to create a control group that ignored their teeth completely for a long time — something that would likely be harmful enough to be considered unethical. But there’s mounting evidence that shows an association between poor dental hygiene and a wide variety of ills.

You should visit the dentist at least once a year, and the ADA recommends that you brush twice a day for two minutes and floss once a day. If you choose to ignore their advice, you’ll get cavities, sure — but here are 13 other things you’re at risk of, some more common than others.

You Asked: Why Are My Teeth So Senstitive?

You Asked: Why Are My Teeth So Sensitive? Illustration by Peter Oumanski for TIME

Sometimes teeth are just touchy. But certain sensitivities are signs of trouble.

You feel it when you sip a hot drink or bite into a cool dessert: an ache, an acute stab of pain. Even a sharp breath of cold air might trigger a twinge. “Any tooth sensitivity is trying to tell us something,” says Dr. Matt Messina, an Ohio-based dentist and spokesperson for the American Dental Association. “It may be easy to treat, but something is still causing it.”

For dentists, the most common (and least alarming) sensitivity is an all-over reaction to very cold stimuli, Messina says. Especially if that cold-induced pain is short-lived, you probably don’t have reason to worry. But if the pain is persistent and confined to a specific tooth or area of your mouth, that’s a problem. “That’s often the sign of a micro-crack, a degraded filling or a cavity,” Messina says.

Those conditions, all of which require a dentist’s attention, become more probable if the tooth or area is also sensitive to heat and biting pressure. “If you have reactions to all three—cold, hot, and biting pressure—we could also be talking about some sort of infection in the tooth,” Messina adds.

If you’re dealing with an all-over ache, your gums—not your teeth—may explain your pain. Exposing your gums to irritants or harsh treatment makes them recede. And when they do, they leave exposed the tender roots near the base of your teeth. “Your roots don’t have the same quality of protective enamel as your crowns, so they’re more sensitive,” says Dr. Eugene Ko of the University of Michigan’s department of oral pathology.

Brushing too forcefully, chewing tobacco or allowing the buildup of plaque can all cause your gums to “run away” from your teeth, resulting in temperature sensitivity, Messina says. If you think gum recession might be the cause of your sensitivity, Ko says you may be able to look in a mirror and spot the issue. “The margin where your teeth and gums meet: there may be a change in color, almost like water elevation marks during a drought.”

Some People Get Cavities More Than Others. Here’s Who (and Why)

Some People Get Cavities More Than Others. Here’s Who (and Why)

Sure, we care a lot about our bodily health and mental health — but how often do you prioritize your dental health? (Illustration: Erik Mace for Yahoo Health)

Unless you’re a dentist, chances are you don’t give that much thought to cavities. Along with chickenpox and ear infections, it’s a health issue we tend to associate with the Dora the Explorer set. So the results of a new report from the Centers for Disease Control and Prevention may leave you open-mouthed: One in four of us is walking around with an untreated cavity, and nearly all adults will suffer from tooth decay at some point in their lives.

“We tend to associate cavities with early childhood, but adults actually have the same rate of tooth decay as kids,” says Bruce Dye, DDS, dental epidemiology officer at the National Institute of Dental and Craniofacial Research, who helped to conduct the survey. “It can affect you at any time during your lifespan.”

Considering that tooth care has been programmed into our brains for practically forever — brush twice a day for two minutes, floss daily, and visit the dentist every six months — why are so many adults orally challenged? We get to the root of the problem and reveal surprising ways to keep your pearly whites in peak condition.

Why Do Endodontic Treatments Fail, and When is Non-surgical Retreatment Indicated?
(2 CE Credits)

By Dr. Nima Dayani01

Root canal treatments usually fail if the treatment is carried out inadequately. However, there are some cases in which the treatment has followed the highest standards yet still results in failure. In most of the cases, the endodontic failure results from persistent secondary intra-radicular infection. Extra-radicular infections may also be implicated in the failure of some cases. In addition, it has been claimed that a few cases can fail because of intrinsic or extrinsic non-microbial factors.

The purpose of this lecture is to discuss the etiological factors of failed root canal treatments using a series of clinical cases. It attempts to aid the clinicians choose between surgical and non-surgical management of a failed root canal in an evidence-based manner. In order to maximize success of endodontic retreatment, indications for the non-surgical vs. surgical retreatment of failed endodontic cases are discussed.

Surgical Extrusion For Fractured Teeth

As if falling, getting into a car accident, or being hit in the face by some unexpected, flying object weren’t upsetting enough, the experience could leave you with a broken tooth which may lead to problems in your mouth. There are two difficult to treat fractures that can result from such an occurrence: crown-root and cervical root fractures. Both fractures involve dentin, the bony material forming the tooth, and cementum, the bony material connecting the tooth to the jaw. Crown-root fractures also involve the enamel, which covers the surface of the tooth and is the part you can see. Cervical-root fractures also involve the dental pulp, which is the tissue inside the tooth. Both types of fractures extend below the gum line and can lead to inflammation, recession, or bleeding of the gum tissue, loss of the attachments between the tooth and jaw, or bone loss if the fracture is not treated. All this trouble for mere accidents!

Recurrent heartburn, GERD, and their dental manifestations

How does the acid reflux affect your teeth?

According to the article, “Extra-esophageal manifestations of gastroesophageal reflux,” published in the June 2007 issue of Oral Diseases, 35-40% of adults in the western world are affected by gastroesophageal reflux disease (GERD), and 10% of ear, nose, and throat doctor visits are GERD-related complaints. Symptoms such as sore throat, hoarseness, or coughing may be signs of GERD, but GERD does not only affect the throat. Patients affected by GERD are also at risk for dental erosions.
