DontPutOffGettingTreatmentforYourSensitiveTeeth

While out with friends one evening, you take a bite of ice cream. Suddenly, pain shoots through your teeth. It only lasts a second, but it's enough to ruin your good time.

This could be tooth sensitivity, a painful reaction to hot or cold foods. It often occurs when the enamel in prolonged contact with acid has eroded. Acid is a waste product of bacteria found in plaque, a thin film of food particles that builds up on tooth surfaces due to inadequate brushing and flossing. Enamel normally mutes temperature or pressure sensation to the underlying dentin layer and nerves. Loss of enamel exposes the dentin and nerves to the full brunt of these sensations.

Sensitivity can also happen if your gums have shrunk back (receded) and exposed dentin below the enamel. Although over-aggressive brushing can often cause it, gum recession also happens because of periodontal (gum) disease, a bacterial infection also arising from plaque.

The best way to avoid tooth sensitivity is to prevent enamel erosion or gum recession in the first place. Removing accumulated plaque through daily brushing and flossing is perhaps the most essential part of prevention, along with a nutritious diet low in sugar and regular dental cleanings and checkups.

It's also important to treat any dental disease that does occur despite your best hygiene efforts. Gum disease requires aggressive plaque removal, especially around the roots. While receded gum tissues often rebound after treatment, you may need gum grafting surgery to restore lost tissues if the gums have receded more deeply. For enamel erosion and any resulting decay you may need a filling, root canal treatment or a crown, depending on the depth and volume of structural damage.

While you're being treated you can also gain some relief from ongoing sensitivity by using a toothpaste with potassium nitrate or similar products designed to desensitize the dentin. Fluoride, a known enamel strengthener, has also been shown to reduce sensitivity. We can apply topical fluoride directly to tooth surfaces in the form of gels or varnishes.

Don't suffer through bouts of tooth sensitivity any more than you must. Visit us for a full exam and begin treatment to relieve you of the pain and stress.

TheSimpleBitewingX-RayisaGameChangerforMaintainingDentalHealth

X-rays are such a routine part of dental care that it's easy to overlook how much this technology has revolutionized detecting and treating tooth decay. It's safe to say x-rays have helped save hundreds of millions of teeth over the last hundred years.

Thanks to its unique properties these invisible electro-magnetic waves give us precise images of the interior structure of teeth and gums. It's so precise that we can clearly detect even a small spot of softened, decayed tooth structure on an exposed x-ray film, often before it becomes visible to the naked eye. As a result, we can begin treating the decay earlier, minimizing the damage and increasing the chances for preserving the tooth.

There are a variety of ways we can utilize x-ray technology in diagnosing dental problems. The one, though, that's used the most is called the bitewing. The name comes from wing-like tabs extending out from a thin frame holding a segment of unexposed film. A technician places the frame inside the patient's mouth with the film on the tongue side of the teeth, and has them bite down on the tabs to hold the frame still. They then aim a camera at the patient's outer cheek, which then emits a very short burst of x-ray energy to expose the film.

Bitewings are popular because they give a full view of the back and side teeth, where decay is often hard to detect, with very little radiation exposure to the patient. And as x-ray technology has progressed over the years with digital processing and more efficient equipment, we can acquire sharper images with even less exposure. We've also developed standard protocols for when and how often we perform x-rays, so that we're getting the most diagnostic benefit for the least amount of exposure time.

Those few minutes getting an x-ray may seem routine, but the benefits to your dental health are truly amazing. The bitewing and other forms of x-rays play a huge role in helping us keep your teeth as healthy as they possibly can.

YouMayNeedYourDentistsHelpEasingthePainofSevereCankerSores

Canker sores, known medically as aphthous ulcers, are fairly common among people. Lasting for about a week or so, these mouth sores are usually more irritating than painful. But about a quarter of the population, especially women, frequently suffer from an acute form that doesn't often respond well to over-the-counter remedies.

A typical canker sore is usually round with a yellow-gray center ringed by a reddened "halo." They can be preceded by tingling or painful sensations at the site a few hours or so before breaking out. Recurrent aphthous stomatitis (RAS) is the more severe form of canker sore, often with outbreaks of multiple painful sores. While the more common sore is usually less than a centimeter in diameter, RAS sores are often much larger.

Canker sores often arise during periods of stress or anxiety, and seem to be connected with eating certain acidic foods like tomato sauce, citrus fruits or spicy dishes. RAS also seems to be related to underlying systemic conditions like vitamin deficiencies, anemia or digestive disorders. Besides managing diet and stress, people with regular canker sores and milder cases of RAS can often find relief with non-prescription numbing agents often found in stores and pharmacies.

For more severe RAS, though, you may need the help of your dentist or physician with treatments like prescription steroids or other medications that come in gel or rinse form or through injections. The goal of any treatment approach is to decrease pain severity and shorten healing times after an outbreak.

While most mouth sores, including RAS, aren't dangerous to your health, you should still take any sore seriously. You should especially seek medical evaluation if a sore doesn't heal after a couple of weeks, if they seem to come more frequently and are more severe, or if you don't seem to ever be without a sore in your mouth. These could indicate a serious underlying problem that needs to be addressed.

One thing's for sure: there are ways to ease your suffering if you have frequent bouts with regular canker sores or even RAS. Talk to your dentist about ways to minimize your discomfort from these irritating mouth sores.

SingerDuaLipaSeestheWisdominPostponingTourDates

When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.

“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”

The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”

A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.

It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.

So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!

If you would like more information about wisdom tooth extraction, please call our office to arrange a consultation. You can learn more in the Dear Doctor magazine articles “Wisdom Teeth” and “Removing Wisdom Teeth.”

KeepingtheLidonAcidtoProtectYourToothEnamel

Enamel — that tough, outermost tooth layer — protects your teeth from all sorts of hazards, from bacterial attack to temperature extremes. But although the hardest substance in the human body, enamel has a mortal enemy — acid. High acid levels can cause the minerals in enamel to dissolve, a process called de-mineralization. And although saliva can neutralize these levels in approximately 45-60 minutes and restore some of the enamel’s lost minerals, a constant acidic environment can overwhelm this natural mechanism.

That’s why you should be careful with the amount and frequency of acidic foods and drinks like citrus fruits or coffee. You should be especially concerned about your intake of sodas, energy drinks or sports drinks. The latter in particular are designed to replace fluids and nutrients during intense exercise or sports events, but are often consumed as a regular beverage. And all these drinks mentioned are often sipped on throughout the day, resulting in a constant wash of acid in your mouth that can interrupt the protective response of saliva.

There’s one other source for high mouth acidity that comes not from outside the body but from within. GERD — Gastro Esophageal Reflux Disease — is a condition in which digestive acid refluxes (flows back) into the esophagus. While chronic acid reflux can damage the lining of the esophagus and lead to ulcers or even cancer, it may also pose a danger to teeth if the acid regularly rises into the mouth. Individuals encountering this will know it by the awful, acrid taste of vomit in their mouth.

To reduce the chances of high mouth acid due to food intake, limit the consumption of acidic foods and beverages to meal times and sports drink consumption to strenuous exercise or sporting events. Better yet, consider the greatest hydrator of all, water — with a neutral pH of 7.

If you’re experiencing chronic heartburn or other GERD symptoms, make an appointment to see your primary care doctor or a gastroenterologist as soon as possible. Many treatments are effective and will not only improve your general health but may also help preserve your tooth enamel.

If you would like more information on the effect of acid in the mouth and how to reduce it, please contact us or schedule an appointment for a consultation.
