Thousands of years ago, our ancestors could only expect to live between 30 and 40 years. But steady improvements in lifestyle and medical care have increased human life expectancy to almost 80 years.

Although a welcome development, it does raise a question: Are our teeth up to the added years? Even though quite resilient, it's natural for teeth to wear after years and tens of thousands of meals biting and chewing.

Fortunately, there have also been phenomenal advances in dental restorations that can effectively replace teeth we lose along the way. Even so, the most advanced artificial replacements can't restore the full benefit of natural teeth to oral and general health. The ideal goal is to preserve and protect our natural teeth for as long as possible.

Here are 4 areas worthy of your attention in protecting your teeth throughout your lifetime.

Dental disease. Tooth decay and periodontal (gum) disease are the top causes for poor dental health and tooth loss. They're caused by bacteria living and feeding primarily in dental plaque, a thin biofilm on tooth surfaces. Brushing and flossing daily, along with regular dental cleanings, removes this disease-causing plaque. You should also seek treatment as soon as possible at the first sign of dental disease.

Bite correction. A poor bite is more than a smile problem: Teeth out of alignment and not engaging normally with their counterparts on the other jaw may increase tooth wear and make hygiene more difficult to perform. Orthodontic treatment, even if undertaken later in life, can help maintain your teeth's long-term health and longevity.

Bad habits. Your teeth are tough, but not indestructible. Protect them by avoiding harmful habits or practices like crunching ice, gnawing on pencils, nails or other hard objects, cracking open nuts or using your teeth as tools. Not engaging in these kinds of habits will help reduce wear and help you also avoid chipping and fractures.

Teeth grinding. Involuntarily clenching or grinding your teeth, often while sleeping, can accelerate dental wear. If you suspect you have this habit, take steps first to deal with stress, the number one cause of adult teeth grinding. Your dentist can also fashion a mouth guard that prevents your teeth from making solid contact with each other and thus help reduce wearing to your teeth.

Heartburn is a big problem: Each year we Americans spend around $10 billion on antacid products, twice as much as for over-the-counter pain relievers. It's an even bigger problem because many indigestion sufferers actually have acid reflux or GERD (gastroesophageal reflux disease), a chronic disease that can cause physical harm—including to teeth.

That's why we've joined with other healthcare providers for GERD Awareness Week, November 17-23, to call attention to the causes and consequences of this disease. In addition to the harm it poses to the esophagus (the “tube” leading from the mouth to the stomach through which food passes), GERD could also damage your teeth to the point of losing them.

GERD is usually caused by the weakening of the lower esophageal sphincter, a ringed muscle located at the junction between the esophagus and the stomach. It acts as a “one-way valve” allowing food into the stomach, but not back into the esophagus. If it weakens, powerful stomach acid can come back into the esophagus and possibly even the mouth. The latter scenario poses a danger to teeth's protective layer of enamel.

Although tough and durable, enamel softens after prolonged contact with acid. Oral acid isn't all that unusual—acid levels typically rise right after eating, causing a temporary softening of enamel. Our saliva, however, goes to work to bring down those acid levels and stabilize enamel.

But if stomach acid enters the mouth because of GERD, the increased acidity can overwhelm saliva's ability to neutralize it. This can lead to enamel erosion, tooth decay and ultimately tooth loss. The enamel damage can be so pronounced that dentists are often the first to suspect GERD.

If you're diagnosed with GERD, here's what you can do to protect your teeth.

• Manage your GERD symptoms through medication, avoidance of spicy/acidic foods, alcohol, caffeine or tobacco products, and maintaining an optimum weight;
• Stimulate saliva by drinking more water, using saliva boosters, or (with your doctor's consent) changing from medications that may be restricting saliva flow;
• Speak with your dentist about strengthening your enamel with special toothpastes or mouthrinses containing extra fluoride or amorphous calcium phosphate (ACP).

You should also brush and floss daily to lower your risk of dental disease, but with one caveat: Don't brush your teeth during or immediately after a reflux episode, as you might remove microscopic bits of softened enamel. Instead, rinse your mouth with water mixed with a half-teaspoon of baking soda (an acid neutralizer) and wait about an hour to brush. The extra time also gives saliva time to further neutralize any remaining acid.

GERD can be unpleasant at best and highly destructive at worst. Don't let it ruin your teeth or your smile.

Love at first sight—it's an endearing notion found in movies and novels, but perhaps we're a little skeptical about it happening in real life. Then again, maybe it does once in a blue moon.  According to supermodel Gisele Bündchen, something definitely happened the first time she met pro quarterback Tom Brady in 2006. And it all began when he smiled.

“The moment I saw him, he smiled and I was like, 'That is the most beautiful, charismatic smile I've ever seen!'” Bündchen said in an article for Vogue magazine. That was all it took. After a three-year romance, they married in 2009 and have been happily so ever since.

Both Brady and Bündchen have great smiles. But they also know even the most naturally attractive smile occasionally needs a little help. Here are three things our happy couple have done to keep their smiles beautiful—and you could do the same.

Teeth whitening. Bündchen is a big proponent of brightening your smile, even endorsing a line of whitening products at one point. And for good reason: This relatively inexpensive and non-invasive procedure can turn a dull, lackluster smile into a dazzling head-turner. A professional whitening can give you the safest, longest-lasting results. We can also fine-tune the whitening solution to give you just the level of brightness you want.

Teeth straightening. When Bündchen noticed one of her teeth out of normal alignment, she underwent orthodontic treatment to straighten her smile. Rather than traditional braces, she opted for clear aligners, removable trays made of translucent plastic. Effective on many types of orthodontic problems, clear aligners can straighten teeth while hardly being noticed by anyone else.

Smile repair. Brady is a frequent client of cosmetic dentistry, sometimes due to his day job. During 2015's Super Bowl XLIX against the Seattle Seahawks, Brady chipped a tooth, ironically from “head-butting” his Patriots teammate Brandon LaFell after the latter caught a touchdown pass. Fortunately, he's had this and other defects repaired—and so can you. We can restore teeth as good as new with composite resin bonding, veneers or crowns.

This superstar couple, known for their advocacy of all things healthy, would also tell you a beautiful smile is a healthy one. You can help maintain your smile's attractiveness with daily brushing and flossing to lower the risk of staining and dental disease, regular dental visits, and “tooth-friendly” eating habits.

And when your teeth need a little extra TLC, see us for a full evaluation. You may not be in the spotlight like this celebrity couple, but you can still have a beautiful smile just like theirs.

One of the major signs that a young person's dental development is nearing completion is the eruption of the last four permanent teeth: the third molars, located rear-most on either side of both the upper and lower jaws. But the advent of these molars, also called wisdom teeth, isn't always a cause for celebration: They can give rise to serious dental problems.

Wisdom teeth often arrive on an already crowded jaw, making them subject to erupting out of position or becoming impacted, totally or partially submerged in the gums. This can cause harm not only to themselves, but also to other teeth: They can impinge on and damage the roots of their neighbors; impede brushing and flossing and increase the risk of disease; and skew the alignment of other teeth to create poor bites that affect dental health and function.

Wisdom teeth are considered so prone to these problems (an estimated 70% between ages 20 and 30 have at least one impacted molar) that it's been a common practice to remove them before they show signs of disease or poor bite development. As a result, third molar extractions are the most common surgical procedure performed by oral surgeons.

But the dental profession is now reevaluating this practice of early removal. On the whole, it's difficult to predict if the eruption of wisdom teeth in a particular person will actually lead to problems. It may be premature, then, to remove wisdom teeth before there's sufficient evidence of its necessity.

As a result, many dentists now follow a more nuanced approach to wisdom teeth management. An impacted wisdom tooth that's diseased or contributing to disease is an obvious candidate for removal. But if the eruption is proceeding without signs of impaction, disease or poor bite development, many providers recommend not removing them early. Instead, their development is allowed to continue, although monitored closely.

If signs of problems do begin to emerge, then removal may again be an option. Until then, a more long-term watchful approach toward wisdom teeth may be the best strategy for helping a young person achieve optimal dental health.
