As tough as teeth are, life can take its toll on them and sometimes lead to parts of them chipping off. Although it might not affect a tooth's overall health, it can certainly downgrade its appearance.
But we can restore a chipped tooth like new, and it may not require extensive dental work. Thanks to a versatile dental material called composite resin, we can often bring back a tooth's natural appearance in just one visit.
Tooth-colored resins have been around for decades, but their application has been limited due to issues with durability. Recently developed bonding techniques, though, have made them a workable option for restoring mild to moderate tooth defects.
We do this by applying and bonding the composite resin to a tooth to “fill in” the missing portion. While it's often a short process, it does require a thorough understanding of tooth anatomy, function and aesthetics.
We begin with a comprehensive exam to assess the true condition of a chipped tooth. Some dental defects might be better served with a porcelain restoration like a veneer or crown for best results. Still, there are a wide range of defects for which composite resins is a solid repair choice.
Once we've determined bonding is appropriate, we prepare the tooth by first roughening its outer surface and then etching it with an acid solution to increase bonding strength. We then apply a luting agent, a kind of dental cement, also to aid with bonding.
We then begin applying the composite resin in liquid form, one layer at a time. This layering process helps simulate the color depth and shape of the tooth, and to further incorporate strength into the restoration. We're also careful at this point to match the variations of color with those of the surrounding teeth so that it looks as natural as possible.
As we finish each layer, we apply a curing light to harden the resin. We can then polish the finished product and make adjustments for the bite. The end result is a tooth that not only looks whole, but natural and blended with the rest of your teeth. Bonding could truly change your smile in just one visit.

Your gums play an important role in dental function and health. Not only do they help anchor teeth in the jaw, the gums also protect tooth roots from disease.
But you can lose that protective covering if your gums recede or shrink back from the teeth. An exposed tooth is more susceptible to decay, and more sensitive to temperature and pressure.
Here are 4 causes for gum recession and what you can do about them.
Gum disease. The most common cause for gum recession is a bacterial infection called periodontal (gum) disease that most often arises from plaque, a thin film of bacteria and food particles accumulating on teeth. Gum disease in turn weakens the gums causes them to recede. You can reduce your risk for a gum infection through daily brushing and flossing to remove disease-causing plaque.
Genetics. The thickness of your gum tissues is a genetic trait you inherit from your parents. People born with thinner gums tend to be more susceptible to recession through toothbrush abrasion, wear or injury. If you have thinner tissues, you’ll need to be diligent about oral hygiene and dental visits, and pay close attention to your gum health.
Tooth eruption. Teeth normally erupt from the center of a bony housing that protects the root. If a tooth erupts or moves outside of this housing, it can expose the root and cause little to no gum tissue around the tooth. Moving the tooth orthodontically to its proper position could help thicken gum tissue and make them more resistant to recession.
Aggressive hygiene. While hard scrubbing may work with other cleaning activities, it’s the wrong approach for cleaning teeth. Too much force applied while brushing can eventually result in gum damage that leads to recession and tooth wear. So, “Easy does it”: Let the gentle, mechanical action of the toothbrush bristles and toothpaste abrasives do the work of plaque removal.
While we can often repair gum recession through gum disease treatment or grafting surgery, it’s much better to prevent it from happening. So, be sure you practice daily brushing and flossing with the proper technique to remove disease-causing plaque. And see your dentist regularly for cleanings and checkups to make sure your gums stay healthy.

Keeping your child’s teeth and gums healthy may sometimes seem like “one step forward, two steps back.” You do all the right things like daily brushing and flossing, and keeping sugar consumption to a minimum. But they’re still getting too many cavities.
We can add something else to what you’re already doing to decrease their cavity rate: apply a concentrated fluoride mixture (stronger than what’s found in toothpaste or drinking water) directly to their teeth. Studies have shown that topical fluoride is effective at reducing the risk of new cavities in children at high risk for decay, and may even reverse early decay.
Topical fluoride can be applied as a gel, foam or varnish. The particular method used depends on factors like the child’s age or the preference of the dentist. But any of the three methods can deliver a short-term, high dose of fluoride to the teeth.
As a result, the burst of fluoride strengthens tooth enamel against decay, with plenty of evidence of its effectiveness. As such, the American Dental Association recommends periodic topical fluoride applications for children older than 6, and especially those that appear to be at higher risk for decay.
You might, however, be concerned about the long-term health effects of these stronger concentrations of fluoride. Again, research indicates that the only long-term hazard associated with too much fluoride is a condition called fluorosis, which produces heavy tooth staining. Fluorosis, though, is more of an appearance issue and doesn’t harm the tooth itself. And it can be avoided in the case of topical fluoride by performing the procedure correctly and conservatively.
There’s also a short-term risk of a reaction to the fluoride mixture if the child swallows too much during the procedure, which could cause stomach upset and pain, vomiting or headaches. We can avoid this by using precautions like dental dams and other isolation methods to prevent the child from ingesting it.
Using proper precautions and procedures, topical fluoride is a safe and effective way to give your child added protection against decay. Avoiding this destructive disease can help ensure they’ll enjoy good dental health for the rest of their lives.
