You've heard it. Your parents heard it—maybe even your grandparents too. Dentists have been alerting people for more than half a century that high sugar consumption contributes to tooth decay.
That message hasn't changed because the facts behind it are the same in the 2020s as they were in the 1950s: The bacteria that cause tooth decay feast on sugar and other leftover carbohydrates in the mouth. This causes them to multiply and increase their production of acid, which softens and erodes tooth enamel.
What has changed though, especially over the last couple of decades, is a growing understanding of how sugar consumption may affect the rest of the body. Just like the evidence of sugar's relationship to tooth decay, current scientific studies are now showing there are strong links between sugar and diseases like diabetes, heart disease and liver disease.
What's startling about what researchers are finding is that cases of these diseases are growing, Especially in younger people. This is a parallel trend to our skyrocketing increases in per capita sugar consumption: the average American now eats the equivalent of 19.5 teaspoons of added sugar every day. Health experts generally agree we should consume no more than 6 teaspoons a day, and children 4.
This is vastly more than we consumed a generation ago. One reason is because processed food manufacturers have increased sugar in their products, hiding under technical, unfamiliar names in ingredient lists. But it's still sugar, and an estimated 74% of processed foods contain some form of it.
But the real surge in sugar has come from our increasing consumption of sodas, as well as energy and sports beverages. These beverages are high in sugar—you can meet your daily allowance with just one 12-oz can of soda. These beverages are now the leading source of sugar in our diets, and, according to experts, a highly dangerous way to consume it.
In effect, dentists of old were on to something: too much sugar is bad for your teeth. It now turns out that it may be bad for your overall health too. Strictly limiting it in your family's diet could help lower your risk of tooth decay and dangerous diseases like diabetes.
Protecting a child's primary (“baby”) teeth from tooth decay should be a top priority. If one is lost prematurely due to decay, it could cause the permanent tooth to misalign when it comes in.
The basic prevention strategy for every child is daily brushing and flossing and regular dental visits. But children at higher risk for decay may need more: Â additional fluoride applied to teeth enamel during office visits.
This natural mineral has been shown to strengthen enamel, teeth's protective layer against decay, especially during its early development. Enamel is composed of calcium and phosphate minerals interwoven to form a crystalline structure called hydroxyapatite. Fluoride joins with this structure and changes it to fluorapatite, which is more resistant to mouth acid than the original structure.
We mostly receive fluoride through fluoridated drinking water and dental care products like toothpaste. Topical fluoride takes it a step further with a stronger dose than found in either of these sources. It can be applied with a foam, varnish or gel using an isolation tray (foam or gel) or painted onto the enamel (varnish or gel).
But does topical fluoride effectively reduce the occurrence of decay? Research indicates yes: a recent review of 28 studies involving over 9,000 children found an average 28% reduction in decayed teeth in children who underwent topical fluoride treatments.
There is, though, one potential side effect: children who swallow the fluoride substance can become sick and experience headache, stomach pain or vomiting. This can be avoided with proper precautions when applying it; the American Dental Association also recommends using only varnish for children younger than 6 years. It's also recommended that children receiving gel or foam not eat or drink at least thirty minutes after the treatment (those who receive the varnish aren't restricted in this way).
Topical fluoride is most effective as part of an overall prevention strategy. Besides daily hygiene and regular dental visits, you can also help reduce your child's decay risk by limiting the amount of sugar in their diet. Sealants, which are applied to the nooks and grooves of teeth where plaque can build up, may also help.
Although techniques and materials have changed, dentists still follow basic principles for treating tooth decay that date from the late 19th Century. And for good reason: They work. These principles first developed by Dr. G.V. Black—the "father of modern dentistry"—are widely credited with saving millions of teeth over the last century.
One of the most important of these treatment protocols is something known as "extension for prevention." In basic terms, it means a dentist removes not only decayed tooth structure but also healthy structure vulnerable to decay. But although effective in saving teeth, practicing this principle can result in loss of otherwise healthy tissue, which can weaken the tooth.
But with new advances in dentistry, decay treatment is getting an overhaul. While Dr. Black's time-tested protocols remain foundational, dentists are finding new ways to preserve more of the tooth structure in a concept known as minimally invasive dentistry (MID).
Better diagnostic tools. Because tooth decay can ultimately infect and damage the tooth's interior, roots and supporting bone, the best way to preserve more of the tooth structure is to treat it as early as possible. Now, new diagnostic tools like digital x-rays, microscopic magnification and optical scanning are helping dentists detect and treat decay earlier, thus reducing how much tissue is removed.
Better prevention methods. Oral hygiene and regular dental care are our basic weapons in the war with tooth decay. In addition, utilizing topical fluoride in combination with a milk-derived product called CPP-ACP dentists can get more of the cavity-fighting organic compound into the tooth enamel to strengthen it against acid attack.
Better treatment techniques. Using air abrasion (a fine particle spray that works like a miniature sandblaster) and lasers, dentists can now remove decayed structure with less harm to healthy tissue than with a traditional dental drill. And new, stronger dental fillings like those made with composite resins require less structural removal to accommodate them.
With these innovative approaches, dentists aren't just saving teeth, they're preserving more of their structure. And that can improve your overall dental health for the long-term.

Tooth decay is a destructive oral disease, which along with periodontal (gum) disease is most responsible for tooth loss. And as you age, your disease risk goes up.
One form of decay older people often experience is root cavities. Unlike those occurring in the visible crown, root cavities often occur below the gum line and are especially destructive to tooth structure.
That's because, unlike the crown protected by ultra-hard enamel, the roots are covered by a thin, mineralized material called cementum. Although cementum offers some protection, it can't compare with the decay-resistant capacity of enamel.
The roots also depend on gum coverage for protection. But unfortunately, the gums can shrink back or recede, usually due to gum disease or over-aggressive brushing, and expose some of the root surface. With only the cementum to protect them, the roots can become highly susceptible to decay. If a cavity forms here, it can rapidly advance into the tooth's interior, the pulp, weakening the tooth and increasing its risk of loss.
To stop the decay, we must treat root cavities much like we do with crown cavities: by removing any decayed structure and then filling the cavity. But root cavities are often more difficult to access depending on how far below the gum line they extend. We may need to perform minor gum surgery to expose the cavity to treat it.
But as with any form of tooth decay, the best strategy is to prevent root cavities in the first place. Your first line of defense is a daily hygiene habit of brushing and flossing to remove dental plaque, the main cause for tooth decay. You should also visit your dentist at least twice a year (or more, if recommended) for more thorough cleanings and checkups. Your dentist can also recommend or prescribe preventive rinses, or apply fluoride to at-risk tooth surfaces to strengthen them.
You should also be on the lookout for any signs of gum disease. If you see swollen, reddened or bleeding gums, see your dentist as soon as possible. Stopping possible gum recession will further reduce your risk of root cavities.

Watching your kids dress up in cute, spooky costumes and go out trick-or-treating can be a real thrill. But thinking about the dental damage caused by eating all those sweets might just give you the chills. So is it best to act like a witch and take away all the candy from those adorable little ghosts and goblins?
Relax! According to experts like the American Dental Association, it’s OK to let kids enjoy some sweet treats on special occasions like Halloween—especially if they have been taking good care of their oral hygiene all year long, by brushing twice each day and flossing once every day. But to help keep cavities away from those young smiles, there are some things parents (and everyone else) should understand.
Cavities—small holes in the tooth’s outer surface that result from the decay process—get started when bacteria in the mouth feed on sugar and produce acids. The acids eat away at the hard enamel coating of teeth. If left untreated, decay will eventually reach the soft inner core of the tooth, causing even more serious damage.
There are several ways to stop the process of tooth decay. One is to take away the sugar that decay bacteria feed on. Because this ingredient is common in so many foods, it’s hard to completely eliminate sugar from the diet. Instead, it may be more practical to limit the consumption of sweets. For example, if kids are only allowed to eat sugary treats around mealtimes, it gives the mouth plenty of “downtime,” in which healthful saliva can neutralize the bacterial acids. It also helps to avoid sweets that stick to teeth (like taffy or gummy bears) and those that stay in the mouth for a long time (like hard candy).
Another way to help stop tooth decay is by maintaining top-notch oral hygiene. Decay bacteria thrive in the sticky film called plaque that clings stubbornly to the surfaces of teeth. Plaque can be removed by—you guessed it—effective brushing and flossing techniques. While it’s a good start, brushing alone won’t remove plaque from the spaces between teeth and under the gums: That’s why flossing is an essential part of the daily oral hygiene routine. Helping your kids develop good oral hygiene habits is among the best things you can do to fight cavities.
And speaking of habits, there are a few others that can help—or hurt—your oral health. For example, drinking plenty of water keeps the body hydrated and benefits oral health; but regularly drinking soda and other sweetened or acidic beverages greatly increases the risk of tooth decay. And seeing your dentist on a regular basis for professional cleanings and routine checkups is one of the most beneficial habits of all. Working together, we can help keep tooth decay from turning into a scary situation for kids—and adults too.
