You may be among the one in three Americans who suffer from the pain of tooth sensitivity. Before attempting treatment, though, we must first identify the cause.
Your teeth are made of layers of different organic tissue. The pulp at the center of the tooth contains nerves that transmit pain or pressure sensation to the brain. The pulp is encased by dentin, a layer of tissue composed of tiny tubules that conduct temperature and pressure changes from outside the tooth to the pulp nerves. The hard outer enamel shell shields the dentin from over-stimulation from these sensations.
There are, however, some instances where the dentin may become exposed and cause sensitivity in the tooth. This can occur when the gum tissue recedes and the root of the tooth is exposed to the oral environment. If the root loses its surface coating (referred to as cementum, a cement-like outer layer around the root surfaces) because of over-aggressive brushing (too hard for too long) or advanced periodontal (gum) disease, sensitivity is often the result.
Another instance is enamel erosion. Although made of the hardest substance in the human body, enamel has one major enemy — acid. A high oral acid level brought on by over-consuming acidic foods and beverages or as a symptom of gastric reflux disease dissolves (de-mineralizes) the enamel’s mineral content. Brushing just after eating actually contributes to de-mineralization because the enamel is in a softer state. It requires forty-five minutes to an hour for your saliva to neutralize acid and restore minerals to the enamel — you may actually be brushing away enamel with this practice.
Once we know the underlying cause, we can use an appropriate method to reduce sensitivity. One way is to reduce nerve sensitivity in the dentin’s tubules or block them altogether. There are several chemical products for both home and dental office application that can reduce sensitivity and encourage enamel re-mineralization (as can the fluoride added to toothpaste). We can also strengthen enamel and provide a mechanical barrier to acid through concentrated fluoride in a varnish applied to tooth and root surfaces. And, life-like restorations like crowns or veneers not only improve the appearance of your teeth, they can also provide coverage for exposed dentin.

During his former career as a professional footballer (that's a soccer star to U.S. sports fans) David Beckham was known for his skill at “bending” a soccer ball. His ability to make the ball curve in mid-flight — to avoid a defender or score a goal — led scores of kids to try to “bend it like Beckham.” But just recently, while enjoying a vacation in Canada with his family, “Becks” tried snowboarding for the first time — and in the process, broke one of his front teeth.
Some fans worried that the missing tooth could be a “red card” for Beckham's current modeling career… but fortunately, he headed straight to the dental office as soon as he arrived back in England. Exactly what kind of treatment is needed for a broken tooth? It all depends where the break is and how badly the tooth is damaged.
For a minor crack or chip, cosmetic bonding may offer a quick and effective solution. In this procedure, a composite resin, in a color custom-made to match the tooth, is applied in liquid form and cured (hardened) with a special light. Several layers of bonding material can be applied to re-construct a larger area of missing tooth, and chips that have been saved can sometimes be reattached as well.
When more tooth structure is missing, dental veneers may be the preferred restorative option. Veneers are wafer-thin shells that are bonded to the front surface of the teeth. They can not only correct small chips or cracks, but can also improve the color, spacing, and shape of your teeth.
But if the damage exposes the soft inner pulp of the tooth, root canal treatment will be needed to save the tooth. In this procedure, the inflamed or infected pulp tissue is removed and the tooth sealed against re-infection; if a root canal is not done when needed, the tooth will have an increased risk for extraction in the future. Following a root canal, a tooth is often restored with a crown (cap), which can look good and function well for many years.
Sometimes, a tooth may be knocked completely out of its socket; or, a severely damaged tooth may need to be extracted (removed). In either situation, the best option for restoration is a dental implant. Here, a tiny screw-like device made of titanium metal is inserted into the jaw bone in a minor surgical procedure. Over time, it fuses with the living bone to form a solid anchorage. A lifelike crown is attached, which provides aesthetic appeal and full function for the replacement tooth.
So how's Beckham holding up? According to sources, “David is a trooper and didn't make a fuss. He took it all in his stride." Maybe next time he hits the slopes, he'll heed the advice of dental experts and wear a custom-made mouthguard…

Although tooth decay is a major problem to watch for in your child’s teeth, it isn’t the only one. As their teeth transition from primary (“baby”) to permanent, you should also be on the lookout for a developing poor bite or malocclusion.
Although the signs can be subtle, you may be able to detect an emerging malocclusion, starting usually around age 6, if you know what to look for. Here are 4 signs your child may be developing a poor bite.
Excessive spacing. This is something that might be noticeable while the child still has their primary teeth. If you notice an excessive amount of space around the front teeth, the sizes of the jaws and the teeth may be disproportional.
Abnormal overlapping. The upper teeth normally just cover the bottom teeth when the jaws are closed. But a malocclusion may be forming if the lower teeth cover the upper (underbite), the upper teeth extend too far over the lower (deep bite) or there’s space between the upper and lower front teeth (open bite).
Different overlapping patterns. Watch as well for some of the teeth overlapping normally while others don’t, a sign of a cross bite. For example, the back upper teeth may cover their counterparts in a normal fashion while the lower front teeth abnormally overlap the top front. The roles here between front and back teeth can also be reversed.
Abnormal eruptions. Permanent teeth normally follow a pattern when erupting, but certain factors could disrupt the process. For example, a jaw that’s developed too small can cause crowding as incoming teeth vie for space; as a result, some permanent teeth may erupt out of their proper position. Likewise, if a baby tooth is out of its normal position or prematurely lost, the permanent tooth may erupt out of position too.
The good news with each of these developing bite problems is that we can correct them or at least minimize their future effect if caught early. So if you notice any of these signs or anything else out of the ordinary, see an orthodontist as soon as possible. It’s also a good idea to have your child undergo a thorough orthodontic evaluation around age 6.
