Today's dental restorations are truly amazing. Not only are they life-like and functional, they can endure for many years a hostile environment of bacteria, acid and heavy biting forces.
Even so, you'll still need to take care of your restorations to help them last. Here's how to extend the life of 3 common forms of dental work.
Fillings. We use fillings, both metal amalgam and tooth-colored materials, to repair holes or cavities in teeth caused by tooth decay. Although strong, dental fillings can break if you subject them to abnormally high biting force (like chewing ice). There's also a chance that if a slight separation occurs between the filling and tooth, bacteria can take up residence and reignite the decay process. To prevent this, practice a daily regimen of oral hygiene to clean away bacterial plaque—and reduce sugar in your diet, a prime food source for bacteria.
Veneers. Usually made of thin porcelain, veneers are bonded to the front of teeth to mask chips, stains, gaps or other blemishes. But although they're strong, veneers aren't immune to damage. Habits like biting nails, the aforementioned ice chewing or unconsciously grinding your teeth could cause a chipped veneer. And if periodontal (gum) disease causes your gums to recede, the exposed part of the tooth may look noticeably darker than the veneer. To protect your veneers and their appearance, avoid habits like ice chewing, and seek treatment for teeth grinding and dental disease.
Bridgework. Bridges are used to replace one or more missing teeth. Traditional bridges use the natural teeth on either side of the gap to support the bridge; for a single missing tooth, implants are a preferable option because they don't require permanently altering the neighboring teeth to support it. With either option, though, you should brush and floss around the restoration to reduce the risk of dental disease. Infections like gum disease or tooth decay could eventually weaken the bridge's supporting teeth or gum disease can damage an implant's gum and bone support.
With any dental restoration, be sure to practice daily oral hygiene, eat a nutritious, low-sugar diet, and see your dentist regularly for cleanings and checkups. Taking care of your dental work will help it take care of you for a long time to come.
Most people associate bacteria with disease and ill health. But the real story about the trillions of microscopic organisms now living in and on your body is a bit more complicated. With recent advances in genetic code research scientists are learning that many of these microorganisms you’re hosting are actually beneficial for you — including your teeth and gums.
Beginning at birth and throughout your lifetime you are continually developing a distinct microbiome — actual communities of bacteria and other microorganisms that inhabit your body. As your microbiome develops it helps train your immune system to distinguish between “good” bacteria that help with digestion and other bodily processes and “bad” bacteria that cause disease.Â And it continually adapts to changes in what we eat, the pets we acquire or the drugs we take.
But lifestyle choices like diet can also have a detrimental effect, causing harmful bacteria to become dominant. This seems to be the case with Streptococcus mutans, the bacterial strain most associated with tooth decay. Scientists have analyzed biofilm (plaque deposits on teeth) from the pre-industrial era before 1900 and compared it with modern biofilm samples. They’ve found Streptococcus mutans levels to be much higher in modern biofilm, which they directly attribute to the modern Western diet.
As we gain a better understanding of these findings and of the role of bacteria in our lives, it could change many health recommendations not only about diet but about medications too. In the fight against disease, for example, we’ve used antibiotics to eradicate infection-causing microorganisms, but with a broad destructive ability that can also kill many beneficial strains of bacteria. It’s hoped as our knowledge grows we’ll be able to create newer drugs that more narrowly target harmful microorganisms while not affecting beneficial ones.
There’s a new appreciation emerging for bacteria’s role in our lives. As a result efforts to rebalance a person’s microbiome when they become sick may eventually become a critical element in healthcare treatment strategies. The benefits of this strategy for health, including for our teeth and gums, could be quite impressive.

You probably know practicing healthy dietary and lifestyle habits can help prevent tooth decay and periodontal (gum) disease. But good habits could also lower your risk for a more dangerous type of disease — oral cancer.
There are several risk factors for oral cancer, including those you can't do much about like your genetic makeup or unknown elements in the environment. But there are factors you can influence with your actions.
You're probably familiar with the links between tobacco use (both smoked and smokeless) and oral cancer. But excessive alcohol use could also increase your risk, as can risky sexual behavior that could expose you to human papilloma virus (HPV) 16.
And what you eat — or don't eat — could also influence your cancer risk. Research over the last half century has uncovered a link between diet and cancer. Cancer development seems to begin with damage to DNA, the genetic material that “tells” each of our cells what it is and what it does in the body. Substances called carcinogens found in the environment — including the foods we eat — can damage our DNA and open the door for cancer to development.
But some foods also contain elements that protect our DNA from carcinogenic damage. Some of these are known as antioxidants, which protect cells from unstable molecules called free radicals. You'll find antioxidants, as well as other protective substances like fiber, vitamins and lycopene in plant-based foods, particularly fruits and vegetables.
Eating a plant-based diet also means you'll eat fewer foods that contribute to the rise of free radicals like saturated fat, animal protein and nitrates (a chemical that occurs in some food processing). A healthy diet, along with quitting tobacco use and moderating alcohol consumption, will help not only preventing decay or gum disease, it will also drastically lower your risk for oral cancer.

Preventing tooth decay is mostly about the basics: daily brushing and flossing followed by regular dental cleanings and checkups. But there’s also a bigger picture: your own personal risk profile for decay based on factors you can modify directly — and those you can’t.
The first type of factor usually involves habits and behavior that either work with your mouth’s natural defenses to fight decay or against it. Besides regular hygiene, your diet is probably the most important of these you can modify for better dental health.
A diet rich in fresh vegetables, protein and dairy products boosts strong, healthy teeth resistant to decay. Conversely, bacteria thrive on the sugar in many snack foods, while sodas, sports or energy drinks elevate acid levels that soften and erode the minerals in your teeth’s enamel.
Lifestyle habits like tobacco use or excessive alcohol consumption also increase your decay risk. Not only do they promote plaque buildup (the thin film of bacteria and food particles that feeds the decay process), but tobacco especially can impede the body’s natural prevention and healing properties.
Conscientious hygiene practices, a dental-friendly diet and modified lifestyle habits all can help you prevent decay. But diligence may not be enough — there are other possible factors you can’t control or may find difficult to change. For example, you may have a genetic propensity toward certain bacteria that cause decay. You may have a condition like gastric reflux that increases the mouth’s acid level. You may also be taking medications that reduce saliva flow, the mouth’s natural acid neutralizer.
But if we know which of these indirect risk factors affect you, we can compensate with extra measures. If enamel strength is a problem we can topically apply fluoride; we can also reduce chronic bacterial levels with prescription rinses. If you have restricted saliva flow, we can attempt to modify your prescriptions through your doctor or prescribe aids that increase saliva.
The key is to investigate your complete risk factor profile through a thorough dental examination. Once we know everything about your mouth, life and health that increases your decay risk, we can put in place a balanced strategy of prevention and treatment just for you. Doing so will greatly increase your chances for keeping your teeth decay-free and healthy.

Brushing and flossing your teeth provides a lot of benefits, including a brighter smile and fresher breath. But the primary benefit—and ultimate goal—is removing dental plaque. This biofilm of bacteria and food remnants on tooth and gum surfaces is the number one cause for dental disease.
Brushing and flossing can effectively keep plaque under control. Unfortunately, plaque can be a stubborn foe, hiding in areas easily missed if you're not thorough enough.
So how do you know you're doing a good job brushing and flossing? One quick way is to use your tongue or dental floss to feel for any grittiness, a possible sign of remaining plaque. Ultimately, your dentist or hygienist can give you the best evaluation of your hygiene efforts during your three or six-month checkup.
But there's another way to find out more definitively how well you're removing plaque in between dental visits: a plaque disclosing agent. These over-the-counter products contain a dye solution that stains plaque so it stands out from clean tooth surfaces.
A disclosing agent, which can come in the form of tablets, swabs or a liquid, is easy to use. After brushing and flossing, you apply the agent according to the product's directions. The dye reacts with plaque to stain it a distinct color. You may also find products with two-tone dyes that stain older and newer plaque different colors to better gauge your overall effectiveness.
You then examine your teeth in the bathroom mirror, looking especially for patterns of missed plaque. For example, if you see dyed plaque running along the gum line, you'll know you need to concentrate your hygiene there.
After observing what you can do to improve your future efforts, you can then brush and floss your teeth to remove as much of the dyed plaque as you can. The staining from the dye is temporary and any remaining will fade over a few hours.
Using a disclosing agent regularly could help you improve your overall hygiene technique and reduce your risk of disease. Ask your dentist for recommendations on products.
