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.

Although primary (“baby”) teeth have a lifespan of only a few years, they’re still important to a child’s current and future dental health. In the present, they help a child eat, speak and smile properly. They also help create a healthy future as placeholders for developing permanent teeth yet to come in.
If, however, a child loses a primary tooth prematurely due to decay, the corresponding permanent tooth could come in misaligned. That’s why we do what we can to help a decayed primary tooth reach its full lifespan. And there are different ways to do this depending on the type of tooth.
With front teeth, which don’t encounter the same chewing forces as those in the back, we may use a tooth-colored filling. This approach is also preferable for appearance’s sake since front teeth are highly visible when a child speaks or smiles.
Primary molars, on the other hand, need a more robust solution. A filling may not be able to withstand the level of long-term chewing forces that these back teeth normally encounter. And because they’re less visible than front teeth, there’s less concern about aesthetics.
That’s why many pediatric dentists prefer stainless steel crowns for molars. Just like their permanent teeth counterparts, a primary crown fits over and completely covers a tooth. They’re typically pre-formed, coming in different shapes and sizes that can then be customized for the tooth in question. After preparing and removing any decayed material from the tooth, we can usually install the crown in one visit with local anesthesia and a sedative (if the child needs it for anxiety).
While a steel crown isn’t the most attractive restoration, it typically handles the higher chewing forces in the back of the mouth better and longer than a filling. That’s especially critical for primary molars, which are some of the last teeth to fall out (as late as ages 10-12). And besides preserving it as a permanent tooth placeholder, a crown also helps the tooth function effectively in the present.
Regardless of what method we use, though, preserving primary teeth is a primary goal of pediatric dentistry. And with a stainless steel crown, we can keep those important back molars functioning for as long as they’re intended.

It might seem that supermodels have a fairly easy life — except for the fact that they are expected to look perfect whenever they’re in front of a camera. Sometimes that’s easy — but other times, it can be pretty difficult. Just ask Chrissy Teigen: Recently, she was in Bangkok, Thailand, filming a restaurant scene for the TV travel series The Getaway, when some temporary restorations (bonding) on her teeth ended up in her food.
As she recounted in an interview, “I was… like, ‘Oh my god, is my tooth going to fall out on camera?’ This is going to be horrible.” Yet despite the mishap, Teigen managed to finish the scene — and to keep looking flawless. What caused her dental dilemma? “I had chipped my front tooth so I had temporaries in,” she explained. “I’m a grinder. I grind like crazy at night time. I had temporary teeth in that I actually ground off on the flight to Thailand.”
Like stress, teeth grinding is a problem that can affect anyone, supermodel or not. In fact, the two conditions are often related. Sometimes, the habit of bruxism (teeth clenching and grinding) occurs during the day, when you’re trying to cope with a stressful situation. Other times, it can occur at night — even while you’re asleep, so you retain no memory of it in the morning. Either way, it’s a behavior that can seriously damage your teeth.
When teeth are constantly subjected to the extreme forces produced by clenching and grinding, their hard outer covering (enamel) can quickly start to wear away. In time, teeth can become chipped, worn down — even loose! Any dental work on those teeth, such as fillings, bonded areas and crowns, may also be damaged, start to crumble or fall out. Your teeth may become extremely sensitive to hot and cold because of the lack of sufficient enamel. Bruxism can also result in headaches and jaw pain, due in part to the stress placed on muscles of the jaw and face.
You may not be aware of your own teeth-grinding behavior — but if you notice these symptoms, you might have a grinding problem. Likewise, after your routine dental exam, we may alert you to the possibility that you’re a “bruxer.” So what can you do about teeth clenching and grinding?
We can suggest a number of treatments, ranging from lifestyle changes to dental appliances or procedures. Becoming aware of the behavior is a good first step; in some cases, that may be all that’s needed to start controlling the habit. Finding healthy ways to relieve stress — meditation, relaxation, a warm bath and a soothing environment — may also help. If nighttime grinding keeps occurring, an “occlusal guard” (nightguard) may be recommended. This comfortable device is worn in the mouth at night, to protect teeth from damage. If a minor bite problem exists, it can sometimes be remedied with a simple procedure; in more complex situations, orthodontic work might be recommended.
Teeth grinding at night can damage your smile — but you don’t have to take it lying down! If you have questions about bruxism, please contact us or schedule an appointment for a consultation.
