Teeth can take a lot of force over a lifetime of biting and chewing, thanks to enamel, their outer layer made of the strongest substance in the human body. Unfortunately, they’re not invincible: it’s even possible for you to break or “fracture” a tooth while biting or chewing normally.
Although such a fracture might seem to occur out of the blue, it’s usually related to a condition known as cracked tooth syndrome. It usually occurs in three stages: in the first, miniscule cracks in the outer enamel known as craze lines develop. They’re not immediately dangerous since they only involve the enamel surface; but left untreated they could deepen and progress to the next stage, a larger crack that penetrates the tooth’s underlying dentin.
If allowed to grow, this crack in turn can lead to the third stage, a full fracture that could extend down to the root. A fracture can put the tooth in danger of loss, especially if its inner pulp becomes exposed. To avoid this worst case, it’s best to treat the tooth at the earliest stage possible when craze lines are just developing.
There is a difficulty, though, with detecting craze lines — they’re small, too small to detect normally with x-rays. We, therefore, rely on other methods such as using an instrument called an explorer to feel for cracks, having the patient bite on a stick or rubber pad to replicate pain symptoms or using fiber-optic lighting with special dye stains to highlight possible cracks. Endodontists, specialists in root canals, can use microscopic equipment that’s quite adept at detecting craze lines.
There are also some signs you can be on alert for that might indicate a craze line or crack. If you feel a short, sharp pain — a “wince” — when chewing and releasing food, you could have a crack that hasn’t yet affected the nerves. If a true fracture occurs, the pain will intensify and you may notice pieces of the tooth coming off. If the crack extends to the root, the pain will become greater and more chronic.
It’s important then that you see us for any recurring pain symptoms as soon as possible. If it’s a crack, the sooner it’s treated the better your tooth’s chances for survival.

It would seem the best time to turn your attention to orthodontic problems with your child is when their permanent teeth have come in around early puberty. In fact, you should be attentive much earlier at around 6 years of age.
Here are 3 reasons why an early orthodontic evaluation could be beneficial to your child’s dental health.
We may be able to detect the first signs of a malocclusion. Also known as a poor bite, it’s possible for an experienced dentist or orthodontist to notice the beginning of a malocclusion as the permanent teeth start coming in between ages 6 and 12. Crowding of teeth, abnormal space between teeth, crooked, protruding or missing teeth are all signs that the teeth are not or will not be coming in properly and some type of treatment will eventually be necessary to correct it.
We might spot problems with jaw or facial development. Not all malocclusions arise from faulty erupting teeth position: sometimes they’re caused by abnormal development of the jaw and facial structure. For example, an orthodontist can detect if the upper jaw is developing too narrowly, which can create a malocclusion known as a cross bite. The difference in the source of a malocclusion will determine what present or future treatment will be needed.
We can perform “interceptive” treatment. While braces won’t typically be undertaken until the permanent teeth have come in, there are other treatments that can “intercept” a growing problem to eliminate or lessen future treatment needs. Orthodontists may recommend appliances that help guide incoming teeth, coax impacted teeth to come in fully or expand portions of the upper jaw to normal dimensions.
As with other areas of health, the earlier orthodontic problems are found the better the chances of a successful and less interventional outcome. By having your child examined orthodontically you may be saving money and future difficulties.

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

There are a lot of ways to improve the appearance of your teeth. Some methods can be quite involved like crowns or bridgework, which require extensive alteration of teeth to accommodate them.
Other methods, though, can achieve stunning results with less tooth reduction or alteration to your teeth. Porcelain veneers are one such alternative that literally puts a new face on your teeth. A dental veneer is a thin layer of restorative material (usually porcelain) that is bonded to the outside of a tooth to cover blemishes. They’re an excellent choice for dealing with otherwise healthy teeth with mild to moderate chipping, wearing, staining or slight misalignment.
Veneers can be fashioned to match the shape and texture of the prepared tooth, as well as coloring that blends with neighboring teeth. They’re created by skilled dental lab technicians who use porcelain powder mixed with water to create layers of pliable porcelain laminated together to achieve the appropriate thickness and shape. The veneer is then oven-fired to produce a strong, durable product.
Their use in various dental situations does require some tooth preparation, though normally not as much as other restorative measures — usually no more than 0.5 mm of surface enamel. Removing this small amount will ensure the veneer doesn’t look too thick and bulky once bonded to the tooth.
There are some situations, though, where veneers aren’t the best choice: because they’re mainly a cosmetic solution, they can’t remedy problems like poor tooth position and bite or large discrepancies in root position. And teeth that are heavily decayed may require more extensive dental work to repair and preserve them.
In the right situation, though, veneers can make a huge difference to your smile and last for years, as long as you practice effective oral hygiene and don’t subject them to abnormal biting force (no cracking hard shell nuts with them — they can shatter). In skilled hands, veneers can transform your teeth from embarrassing to dazzling.

If you ever get out of the habit of daily brushing and flossing, you’re setting yourself up for dental disease. Neglecting oral hygiene allows bacterial plaque to build up on tooth surfaces, which can give rise to aggressive gum infections known collectively as periodontal (gum) disease.
Gum disease may first manifest itself as gingivitis, an inflammation of the outer gum tissues around teeth. Resuming hygiene habits could help reduce the infection if it’s detected early enough. If the infection has spread deeper below the gum line, though, brushing and flossing won’t be able to reach and remove the offending plaque — you’ll need our help with that.
The objective of any such treatment is the same as your daily brushing and flossing — remove plaque as well as hardened deposits (calculus) that cause disease. The most basic technique is called scaling in which we use specialized hand instruments (scalers) or ultrasonic equipment to loosen and remove the plaque and calculus from all tooth and gum surfaces.
For deeper plaque, we may need to use a technique called root planing. As its name implies, we use equipment similar to scalers to shave or “plane” plaque, calculus, bacteria or other toxins from the roots that have become ingrained in their surfaces.
These procedures are often carried out with local anesthesia to ensure patient comfort and allow us to be as meticulous as possible with plaque and calculus removal. It’s imperative that we remove as much plaque and calculus as possible, and which often involves more than one session. This is because as the gum tissues become less inflamed it allows us to access more plaque-infested areas during subsequent sessions.
Hopefully, these techniques will arrest the infection and restore good health to gum tissues. It’s then important for you to recommit and follow through on a renewed daily hygiene regimen to reduce the chances of re-infection that could lead to more serious problems and potential tooth loss.
