What causes stains on teeth?

Staining can occur on the outside surfaces of teeth and is caused by foods such as red wine, coffee, and tea, as well as by tobacco use. They can also be developmental, affecting the structure of the teeth due to excessive fluoride levels or from tetracycline antibiotics given during childhood to name a few. Changes in a tooth's enamel or dentin during tooth formation, or as teeth age, can also cause discoloration.

What is going on inside a tooth's structure that makes it look stained?

Most of a tooth's covering (95 percent) is composed of highly mineralized enamel. The crystals of enamel are contained in a framework, or matrix, of organic matter. Dentists believe that various organic compounds that get into this matrix can cause staining.

How do whiteners work?

Tooth whiteners or bleaches expose the teeth to a peroxide compound. This creates reactive oxygen that breaks down highly colored organic compounds within the tooth's sub-surface matrix, making the tooth look whiter, but without changing its internal structure.

What professional in-office whitening techniques are available?

During treatment, a high concentration of peroxide solution in the form of a gel is applied directly on the teeth, often with activation by a heat or light source. These systems use custom tailored trays fitted to an individual's mouth. Silicone barriers or protective gels are used to keep the peroxide gel away from the gums or sensitive membranes in the mouth.

How are professional home whiteners different?

Home whiteners involve a less concentrated solution of peroxide in a gel form. It is delivered to the tooth surface by a bleaching tray that is custom-made in your dentist's office. Over-the-counter whiteners such as whitening strips or paint-on formulas can also be used, but they take longer and they're not as effective — the more diluted solutions are used for safety.

Can toothpastes really whiten teeth?

Mild abrasives in toothpastes clean surface stains but cannot change the underlying tooth color or remove significant staining.

How long do the results last?

Usually, the results last from six months to two years, but effects will diminish over time. You can make them last longer by avoiding the foods and habits that cause staining.

Are teeth whiteners safe to use?

Teeth whitening products are safe if used according to our recommendations or the product manufacturer's directions. Peroxide products may be toxic if used in excess of recommended intervals and amounts.

Grinding, clenching, and gritting your teeth are common reactions to stress — but their results can be quite complex. Here are some questions and answers that will fill you in on what you may not know about this widespread problem.

My dentist said I was bruxing. What does that mean?
Bruxing means that your teeth are grinding upon each other. Many people carry out this habit subconsciously and are not even aware that they are doing it.

Is bruxing or gritting harmful?
Such habits are called “parafunctional” (from para, meaning outside, and function, meaning purpose). This is because these stress habits exert much larger biting forces — as much as ten times more — than in normal biting and chewing activities. This excess pressure can cause damage to jaw joints and muscles, resulting in muscle spasm and pain; and to the teeth, resulting in wear, fractures or looseness. They can also cause headaches, earaches, and even neck and backaches because of the pressures on various structures in the face and mouth.

What is the usual treatment for problems arising from these stress habits?
The first thing we want to do is relieve your pain and discomfort. Second, we want to stop future damage. Application of heat or cold is helpful, and mild anti-inflammatory and muscle relaxant drugs are prescribed for pain and muscle spasm. To prevent future occurrences, we may treat you with biofeedback or refer you to someone who can offer psychotherapy.

What is a night guard and how can it help?
A night guard is an unobtrusive thin plastic appliance that is made to fit over the biting surfaces of your upper teeth. These guards are so unobtrusive that they can even be worn during the day if your stress level is so high that you grind your teeth during the day. The guard is adjusted to leave the lower teeth free to move against the surface of the guard, but they cannot bite into the upper teeth. This prevents wear on the teeth and lets the jaw muscles relax, preventing the pain of muscle spasm.

Christie Brinkley's world-famous smile has graced the covers of countless magazines for over 30 years. In fact, in her own words from an interview with Dear Doctor magazine, the supermodel said, “I think my smile was really my passport to success in the modeling industry.” And while most of her smile's appeal comes naturally, Christie does give it a boost with good oral hygiene, regular dental checkups and tooth whitening. As Christie says, “When it comes to teeth, keep it as natural as possible. Do not go overboard on whitening. You want your teeth to compliment your face…your friends should not be required to wear sunglasses when you smile!”

Aside from some potential minor side effects such as tooth sensitivity, whitening teeth through bleaching is a relatively inexpensive way to brighten your smile conservatively and successfully. There are three common methods, as described below:

• An external or vital approach where “vital” (living) teeth are bleached through direct contact to the tooth's surface.
• An internal or non-vital approach where the tooth is whitened from the inside during a root canal treatment.
• A combination approach in which both internal and external bleaching techniques are used.

But what causes teeth to become discolored?

Tooth discoloration can be caused by a traumatic blow to your teeth resulting in nerve tissue (pulp) death. However, there can be many other causes: consuming or using products that stain the teeth such as coffee, tea, cola, tobacco products and red wine, to name just a few. Aging is another factor, as it results in changes in the mineral structure of the tooth as the enamel, the outermost layer, loses its beautiful and youthful translucency. Other causes include exposure to high levels of fluoride; tetracycline, an antibiotic, administered during childhood; inherited developmental disorders and jaundice in childhood; and tooth decay.

The good news is that we routinely brighten smiles through tooth whitening.

Model Christie Brinkley's smile has been a symbol of America's optimism since the seventies. Particularly well known for being the cover model for three consecutive Sports Illustrated Swimsuit editions, Brinkley still has a fresh-faced American girl-next-door beauty that starts with her cheerful smile, which transmits the message that all is well.

Brinkley's modeling career began when she was “discovered” in Paris in the seventies, at the age of 18. As she explained in an interview with Dear Doctor magazine, it was like a fairy tale. She had gone to study art in Paris, where a fashion designer spotted her walking down the street. “He told me later he immediately thought, ‘That's the girl!’” she said.

Brinkley attributes her famous smile to a combination of good genetics (she inherited her mother's “beautiful straight teeth”), combined with the intelligence to practice good oral hygiene and have regular dental appointments. She never needed to have work done to prepare her for the modeling life; but as a teenager, she said, she wished she could wear braces because she thought the “coolest kids had them.”

Although dental restorations were not needed to enhance her beautiful natural smile, she did have two dental implants after she fractured two rear molars in a bad helicopter crash while back-country skiing, and she says she is thankful for dental implant technology because it looks and feels so natural.

Brinkley said that her smile led directly to her assignment as spokesperson for a brand of oral rinse and mouthwash products. She is also concerned about the environment. Her company Christie, Inc. is designing environmentally friendly products.

Her advice to everyone is to smile more. “I think a smile makes EVERYONE beautiful! It's the greatest gift we give each other... It's an expression of friendship, love and peace!”

Protecting one's smile is important at any age. This is especially true for people who participate in contact sports or other activities where a trauma to the mouth can occur. While we all tend to believe that we are safe and that injuries “only happen to other people,” we could not be further from the truth. Take, for example, Jillian Michaels, an accomplished author, business mogul, wellness expert, trainer and star of The Biggest Loser. She learned this invaluable lesson after breaking her two front teeth as a child and having them repaired with crowns. As Jillian stated in her interview with Dear Doctor magazine, “Now, I generally wear a mouthguard if I am doing anything where my teeth have any chance of being knocked out.”

We feel obligated to educate our patients so that you can make informed decisions about your oral health. This is why we put together the following brief list of research findings.

Did you know?

• According to the American Dental Association, an athlete is 60 times more likely to suffer harm to the teeth when not wearing a mouthguard.
• The US Centers for Disease Control reports that sports-related dental injuries account for more than 600,000 visits to the emergency room each year.
• People who do not have a knocked-out tooth properly reserved or replanted may face a lifetime cost of $10,000 to $20,000 per tooth, according to the National Youth Sports Foundation for Safety.
• The Academy of General Dentistry estimates that mouthguards prevent more than 200,000 injuries each year.

If feel you and/or your children need a custom-fitted, professionally made mouthguard, contact us today to schedule an appointment. During your private consultation, we will conduct a thorough examination, listen to your concerns, and answer all of your questions as we discuss the best methods for protecting your investment — your own, or your children's, teeth.
