Nothing grabs your attention like a sharp tooth pain, seemingly hitting you out of nowhere while you’re eating or drinking. But there is a reason for your sudden agony and the sooner you find it out, the better the outcome for your oral health.
To understand tooth sensitivity, we need to first look at the three layers of tooth anatomy. In the center is the pulp filled with blood vessels and nerve bundles: it’s completely covered by the next layer dentin, a soft tissue filled with microscopic tubules that transmit sensations like pressure or temperature to the pulp nerves.
The third layer is enamel, which completely covers the crown, the visible part of a tooth. Enamel protects the two innermost tooth layers from disease and also helps muffle sensations so the tooth’s nerves aren’t overwhelmed. The enamel stops at about the gum line; below it the gums provide similar protection and sensation shielding to the dentin of the tooth roots.
Problems occur, though, when the dentin below the gums becomes exposed, most commonly because of periodontal (gum) disease. This bacterial infection caused by dental plaque triggers inflammation, which over time can weaken gum tissues and cause them to detach and shrink back (or recede) from the teeth. This can leave the root area vulnerable to disease and the full brunt of environmental sensations that then travel to the nerves in the pulp.
Tooth decay can also create conditions that cause sensitivity. Decay begins when certain oral bacteria multiply and produce higher than normal levels of acid. The acid in turn dissolves the enamel’s mineral content to create holes (cavities) that expose the dentin. Not treated, the infection can eventually invade the pulp, putting the tooth in danger of being lost unless a root canal treatment is performed to remove the infection and seal the tooth from further infection.
So, if you begin experiencing a jolt of pain while eating or drinking hot or cold foods or beverages, see your dentist as soon as possible to diagnose and treat the underlying cause. And protect your teeth from dental disease by practicing daily brushing and flossing, as well as seeing your dentist for regular dental cleanings and checkups. Don’t ignore those sharp pains—your teeth may be trying to tell you something.

Gastroesophageal reflux disease (GERD) is a digestive disorder that can lead to a number of serious health problems. One of them, tooth erosion, could ruin your dental health.
Your stomach uses strong acids to break down food during digestion. A ring of muscle just above the stomach called the esophageal sphincter works as a one-way valve to allow food contents into the stomach but prevent acid from traveling back up through the esophagus.
GERD occurs when the esophageal sphincter weakens and starts allowing acid into the esophagus and potentially the mouth. The acid wash can eventually damage the esophageal lining, causing pain, heartburn, ulcers or even pre-cancerous cells.
Acid coming up in the mouth can cause the mouth’s normally neutral pH to slide into the acidic range. Eventually, these high acid levels soften and erode tooth enamel, increasing the risk of decay and tooth loss.
Accelerated erosion is often a sign of GERD—in fact, dentists may sound the first warning that a patient has a gastrointestinal problem. Unfortunately, a lot of damage could have already occurred, so it’s important to take steps to protect your teeth.
If you’ve been diagnosed with GERD, be sure to maintain good oral hygiene practices like brushing or flossing, especially using fluoride toothpaste to strengthen enamel. But try not to brush right after you eat or during a GERD episode: your teeth can be in a softened condition and you may actually brush away tiny particles of mineral. Instead, wait about an hour after eating or after symptoms die down.
In the meantime, try to stimulate saliva production for better acid neutralization by chewing xylitol gum or using a saliva booster. You can also lower mouth acid by rinsing with a cup of water with a half teaspoon of baking soda dissolved in or chewing on an antacid tablet.
You can also minimize GERD symptoms with medication, as well as avoiding alcohol, caffeine or spicy and acidic foods. Try eating smaller meals, finishing at least three hours before bedtime, and avoid lying down immediately after eating. Quitting smoking and losing weight may also minimize GERD symptoms.
GERD definitely has the potential to harm your teeth. But keeping the condition under control will minimize that threat and benefit your health overall.

Some people are lucky — they never seem to have a mishap, dental or otherwise. But for the rest of us, accidents just happen sometimes. Take actor Jamie Foxx, for example. A few years ago, he actually had a dentist intentionally chip one of his teeth so he could portray a homeless man more realistically. But recently, he got a chipped tooth in the more conventional way… well, conventional in Hollywood, anyway. It happened while he was shooting the movie Sleepless with co-star Michelle Monaghan.
“Yeah, we were doing a scene and somehow the action cue got thrown off or I wasn't looking,” he told an interviewer. “But boom! She comes down the pike. And I could tell because all this right here [my teeth] are fake. So as soon as that hit, I could taste the little chalkiness, but we kept rolling.” Ouch! So what's the best way to repair a chipped tooth? The answer it: it all depends…
For natural teeth that have only a small chip or minor crack, cosmetic bonding is a quick and relatively easy solution. In this procedure, a tooth-colored composite resin, made of a plastic matrix with inorganic glass fillers, is applied directly to the tooth's surface and then hardened or “cured” by a special light. Bonding offers a good color match, but isn't recommended if a large portion of the tooth structure is missing. It's also less permanent than other types of restoration, but may last up to 10 years.
When more of the tooth is missing, a crown or dental veneer may be a better answer. Veneers are super strong, wafer-thin coverings that are placed over the entire front surface of the tooth. They are made in a lab from a model of your teeth, and applied in a separate procedure that may involve removal of some natural tooth material. They can cover moderate chips or cracks, and even correct problems with tooth color or spacing.
A crown is the next step up: It's a replacement for the entire visible portion of the tooth, and may be needed when there's extensive damage. Like veneers, crowns (or caps) are made from models of your bite, and require more than one office visit to place; sometimes a root canal may also be needed to save the natural tooth. However, crowns are strong, natural looking, and can last many years.
But what about teeth like Jamie's, which have already been restored? That's a little more complicated than repairing a natural tooth. If the chip is small, it may be possible to smooth it off with standard dental tools. Sometimes, bonding material can be applied, but it may not bond as well with a restoration as it will with a natural tooth; plus, the repaired restoration may not last as long as it should. That's why, in many cases, we will advise that the entire restoration be replaced — it's often the most predictable and long-lasting solution.
Oh, and one more piece of advice: Get a custom-made mouthguard — and use it! This relatively inexpensive device, made in our office from a model of your own teeth, can save you from a serious mishap… whether you're doing Hollywood action scenes, playing sports or just riding a bike. It's the best way to protect your smile from whatever's coming at it!
