We’ve been treating one of your decay-prone teeth for some time with one filling after another. Each incident required a little more removal of decayed tooth material until now there isn’t enough structure to support another filling.
We could remove the tooth and replace it with a bridge or a dental implant, both viable restoration options. But keeping the tooth if possible would be more beneficial in the long-run for your gums, bone and remaining teeth. If it still has a healthy and stable root, it’s possible to permanently cover or “cap” the tooth with a life-like crown.
Crowns have been used for decades: the first were mainly composed of metal like gold or silver and later dental porcelain, a ceramic material that could be molded, shaped and oven-fired to resemble a real tooth. The earliest porcelains, though, were brittle, so a hybrid with a metal interior for strength and a fused exterior porcelain layer for appearance came into prominence.
Today, advances in materials have led to all-porcelain crowns strong enough to withstand biting forces. While the metal-porcelain hybrid still account for about 40% of crowns installed annually, the all-porcelain types are steadily growing in popularity.
Regardless of the type, though, the process for fitting any crown is relatively the same. The first step is to reshape the affected tooth so that the future crown will fit over it, followed by an impression mold of the tooth a dental technician will use to form a custom crown. Once the new crown has been prepared, we then permanently bond it to the tooth.
With a crown, you’ll be able to enjoy normal function and have a tooth that looks as healthy and normal as its neighbors. Be aware, though, that your underlying tooth is still subject to decay — so diligent, daily hygiene and regular dental visits are a must. With proper care your newly crowned tooth can continue to serve you and your smile for many years to come.

If you’ve noticed redness or small skin cracks at the corners of your mouth, you may have a common infection known as perleche or angular cheilitis. Depending on its cause, there are ways to treat the redness and skin cracking to lessen your discomfort.
The term perleche comes from the French word “lecher,” meaning to lick. This is derived from the tendency of perleche patients to constantly lick the area to ease irritation; unfortunately, this also helps perpetuate the inflammation. Once the skin is broken the area is commonly infected by yeast called candida albicans.
Initially, perleche may arise from a variety of sources, most of them locally from either inside or around the mouth, although it can be triggered by a general body infection or disease like diabetes or cancer, or vitamin or iron deficiencies. Inside the mouth reduced saliva flow, tissue inflammation under a rarely cleaned denture (denture stomatitis), pressure on the mouth corners caused by a collapsed bite due to missing teeth and similar conditions can elevate the risks for infection. Around the mouth wrinkling or “marionette lines,” deep lines that extend from the mouth to the chin due to aging or environmental exposure, can contribute to crack formation. Drooling during sleep or as a result of orthodontic treatment is also a contributing cause.
The main focus of treatment for perleche is to bring any infection under control. This can be accomplished with a course of oral or topical antifungal (yeast-attacking) medication. If the infection has spread into the mouth or throat we might then prescribe a troche, a small lozenge designed to dissolve, which you would rinse with and then swallow to affect other portions of the mouth. Steroid or zinc oxide ointments applied directly to the skin can control inflammation and serve as a barrier agent with antifungal properties to promote healing.
If the cause is more related to dental problems (ill-fitting dentures or missing teeth), then it’s important to have these addressed and treated. You may also consult a dermatologist for treatments to lessen wrinkling around the mouth that might also contribute to chronic cases of perleche.

Some people are lucky — they never seem to have a mishap, dental or otherwise. But for the rest of us, accidents just happen sometimes. Take actor Jamie Foxx, for example. A few years ago, he actually had a dentist intentionally chip one of his teeth so he could portray a homeless man more realistically. But recently, he got a chipped tooth in the more conventional way… well, conventional in Hollywood, anyway. It happened while he was shooting the movie Sleepless with co-star Michelle Monaghan.
“Yeah, we were doing a scene and somehow the action cue got thrown off or I wasn't looking,” he told an interviewer. “But boom! She comes down the pike. And I could tell because all this right here [my teeth] are fake. So as soon as that hit, I could taste the little chalkiness, but we kept rolling.” Ouch! So what's the best way to repair a chipped tooth? The answer it: it all depends…
For natural teeth that have only a small chip or minor crack, cosmetic bonding is a quick and relatively easy solution. In this procedure, a tooth-colored composite resin, made of a plastic matrix with inorganic glass fillers, is applied directly to the tooth's surface and then hardened or “cured” by a special light. Bonding offers a good color match, but isn't recommended if a large portion of the tooth structure is missing. It's also less permanent than other types of restoration, but may last up to 10 years.
When more of the tooth is missing, a crown or dental veneer may be a better answer. Veneers are super strong, wafer-thin coverings that are placed over the entire front surface of the tooth. They are made in a lab from a model of your teeth, and applied in a separate procedure that may involve removal of some natural tooth material. They can cover moderate chips or cracks, and even correct problems with tooth color or spacing.
A crown is the next step up: It's a replacement for the entire visible portion of the tooth, and may be needed when there's extensive damage. Like veneers, crowns (or caps) are made from models of your bite, and require more than one office visit to place; sometimes a root canal may also be needed to save the natural tooth. However, crowns are strong, natural looking, and can last many years.
But what about teeth like Jamie's, which have already been restored? That's a little more complicated than repairing a natural tooth. If the chip is small, it may be possible to smooth it off with standard dental tools. Sometimes, bonding material can be applied, but it may not bond as well with a restoration as it will with a natural tooth; plus, the repaired restoration may not last as long as it should. That's why, in many cases, we will advise that the entire restoration be replaced — it's often the most predictable and long-lasting solution.
Oh, and one more piece of advice: Get a custom-made mouthguard — and use it! This relatively inexpensive device, made in our office from a model of your own teeth, can save you from a serious mishap… whether you're doing Hollywood action scenes, playing sports or just riding a bike. It's the best way to protect your smile from whatever's coming at it!

There's no doubt about it — dentures have changed your life. Now you can eat and speak normally, and smile again with confidence. But if you're going to continue to benefit from your dentures, you'll need to take care of them. One of the best things you can do is not sleep with them in.
There are a couple of important reasons why you should take your dentures out when you go to bed. First, dentures tend to compress the bony ridges of the gums that support them. This contributes to the loss of the underlying bone, an occurrence common with missing teeth. Wearing dentures around the clock can accelerate this bone loss, which eventually loosens your denture fit.
Constant denture wearing also contributes to mouth conditions conducive to dental disease. You're more likely to develop tongue and denture plaque (a thin film of bacteria and food particles) that can cause gum inflammation or yeast development. The presence of the latter could also trigger a chronic response from your immune system that might make you more susceptible to other diseases.
Good oral hygiene is just as important with dentures as with natural teeth. Besides removing them at night, you should also take them out and rinse them after eating and brush them at least once a day with a soft tooth brush. And be sure to use regular dish or hand soap (especially antibacterial) or denture cleanser — toothpaste is too abrasive for denture surfaces.
It's also a good habit to store your dentures in water or, better, an alkaline peroxide solution. This will help deter plaque and yeast development. And don't forget the rest of your mouth: brush your tongue and gums with a very soft toothbrush (different from your denture brush) or clean them off with a damp cloth.
Taking care of your dentures will ensure two things. You'll lower your risk for disease — and you'll also help extend your dentures' life and fit.
Enamel — that tough, outermost tooth layer — protects your teeth from all sorts of hazards, from bacterial attack to temperature extremes. But although the hardest substance in the human body, enamel has a mortal enemy — acid. High acid levels can cause the minerals in enamel to dissolve, a process called de-mineralization. And although saliva can neutralize these levels in approximately 45-60 minutes and restore some of the enamel’s lost minerals, a constant acidic environment can overwhelm this natural mechanism.
That’s why you should be careful with the amount and frequency of acidic foods and drinks like citrus fruits or coffee. You should be especially concerned about your intake of sodas, energy drinks or sports drinks. The latter in particular are designed to replace fluids and nutrients during intense exercise or sports events, but are often consumed as a regular beverage. And all these drinks mentioned are often sipped on throughout the day, resulting in a constant wash of acid in your mouth that can interrupt the protective response of saliva.
There’s one other source for high mouth acidity that comes not from outside the body but from within. GERD — Gastro Esophageal Reflux Disease — is a condition in which digestive acid refluxes (flows back) into the esophagus. While chronic acid reflux can damage the lining of the esophagus and lead to ulcers or even cancer, it may also pose a danger to teeth if the acid regularly rises into the mouth. Individuals encountering this will know it by the awful, acrid taste of vomit in their mouth.
To reduce the chances of high mouth acid due to food intake, limit the consumption of acidic foods and beverages to meal times and sports drink consumption to strenuous exercise or sporting events. Better yet, consider the greatest hydrator of all, water — with a neutral pH of 7.
If you’re experiencing chronic heartburn or other GERD symptoms, make an appointment to see your primary care doctor or a gastroenterologist as soon as possible. Many treatments are effective and will not only improve your general health but may also help preserve your tooth enamel.
