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.

When Entertainment Tonight host Nancy O’Dell set out to teach her young daughter Ashby how to brush her teeth, she knew the surest path to success would be to make it fun for the toddler.
“The best thing with kids is you have to make everything a game,” Nancy recently said in an interview with Dear Doctor TV. She bought Ashby a timer in the shape of a tooth that ticks for two minutes — the recommended amount of time that should be spent on brushing — and the little girl loved it. “She thought that was super fun, that she would turn the timer on and she would brush her teeth for that long,” Nancy said.
Ashby was also treated to a shopping trip for oral-hygiene supplies with Mom. “She got to go with me and choose the toothpaste that she wanted,” Nancy recalled. “They had some SpongeBob toothpaste that she really liked, so we made it into a fun activity.”
Seems like this savvy mom is on to something! Just because good oral hygiene is a must for your child’s health and dental development, that doesn’t mean it has to feel like a chore. Equally important to making oral-hygiene instruction fun is that it start as early as possible. It’s best to begin cleaning your child’s teeth as soon as they start to appear in infancy. Use a small, soft-bristled, child-sized brush or a clean, damp washcloth and just a thin smear of fluoride toothpaste, about the size of a grain of rice.
Once your child is old enough to hold the toothbrush and understand what the goal is, you can let him or her have a turn at brushing; but make sure you also take your turn, so that every tooth gets brushed — front, back and all chewing surfaces. After your child turns 3 and is capable of spitting out the toothpaste, you can increase the toothpaste amount to the size of a pea. Kids can usually take over the task of brushing by themselves around age 6, but may still need help with flossing.
Another great way to teach your children the best oral-hygiene practices is to model them yourself. If you brush and floss every day, and have regular cleanings and exams at the dental office, your child will come to understand what a normal, healthy and important routine this is. Ashby will certainly get this message from her mom.
“I’m very adamant about seeing the dentist regularly,” Nancy O’Dell said in her Dear Doctor interview. “I make sure that I go when I’m supposed to go.”
It’s no wonder that Nancy has such a beautiful, healthy-looking smile. And from the looks of things, her daughter is on track to have one, too. We would like to see every child get off to an equally good start!

Accidents can happen to your mouth, especially if you have an active lifestyle. For example, a sudden blow to the jaw while playing sports or exercising could result in a chipped tooth. And, while the internal tooth structure may be fine, the effect on your appearance can be disheartening.
Fortunately, we have techniques and materials to restore your smile after an injury. Bonding with composite resin is one such procedure: it’s ideal for mild to moderate chipping, especially in highly visible front teeth.
Composite resin is a dental material made of various substances mixed to match the color and texture of natural teeth. The composite is usually made of inorganic glass filler blended with a plastic-based matrix and joined together with a chemical “coupling” agent. The ratio of filler to matrix will depend on the type of tooth and damage — for example, back teeth, which encounter higher biting forces, require a composite with more filler for added strength.
To begin the procedure, we first prepare the damaged tooth by applying microscopic etchings (often with a chemical solution) that create tiny depressions or “undercuts”: these help create a seamless bond between the composite and the natural tooth. We then apply the composite in layers with a bonding agent, building up layer upon layer until we’ve achieved the desired shape for the tooth involved.
Bonding with composite resins doesn’t require much tooth preparation, can be placed quickly and is relatively inexpensive. Because of the wide spectrum of color possibilities, composite resins are superior to traditional amalgam (metal) restorations in creating a more life-like appearance. Its application, however, can be limited by the amount of tooth structure needing to be replaced: because it isn’t as strong as the tooth structure it replaces, the more tooth structure the bonded composite resin attempts to replace the less likely it can stand up over time to normal bite forces.
Still, composite resins are ideal for mild to moderate damage or disfigurement. If you’ve suffered such an injury, be sure to visit us to see if bonding with life-like composites is the right solution for restoring your smile.
