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.

As a regular part of your daily hygiene you may be using a mouthrinse — or “mouthwash” — mainly to keep your mouth feeling fresh and clean. Some mouthrinses, though, do more than give you fresher breath.
While there are countless mouthrinses available, we can place all of them into two broad categories: cosmetic and therapeutic. The first refresh your mouth and breath, usually with a mentholated or minty taste and smell that masks unpleasant odors. How well they work is mainly subjective: if you feel better after using them, they’ve done their job.
Therapeutic rinses have a different role, intended to improve oral health in some way. We can divide these into anti-cariogenic (decay prevention) or anti-bacterial rinses. You can find fluoride-based anti-cariogenic rinses over-the-counter in retail or drug stores, usually containing about .05% sodium fluoride per volume. Numerous studies have shown these rinses highly effective in preventing tooth decay when used with daily brushing and flossing.
Likewise, over-the-counter antibacterial rinses have proven somewhat effective in reducing bacteria that leads to dental disease. Formulated usually with triclosan, sanguinaria extract, zinc or essential oils, they can also help reduce the incidence of gingivitis (inflammation of the gums), but only if used in conjunction with brushing and flossing.
Perhaps, though, the most widely studied and substantiated therapeutic mouthrinse is chlorhexidine, a prescription-only rinse. Chlorhexidine inhibits the formation of bacterial plaque on tooth surfaces, the main trigger for both tooth decay and periodontal (gum) disease. It’s often used as a post-surgery rinse when brushing and flossing may not be possible, but dentists will often prescribe it for patients who have a high propensity for dental disease.
Using a mouthrinse depends on your current oral health and personal preferences. Therapeutically, most people gain some added tooth strength protection from using a fluoride rinse in their daily hygiene. If fresh breath and the way your mouth feels are important to you, you should consider such a rinse that also has a pleasant taste and effect for you. We can further discuss with you whether a different type of rinse, or a prescription-strength formula, might be best for your particular needs.

Is a chipped tooth big news? It is if you’re Justin Bieber. When the pop singer recently posted a picture from the dental office to his instagram account, it got over 2.6 million “likes.” The snapshot shows him reclining in the chair, making peace signs with his hands as he opens wide; meanwhile, his dentist is busy working on his smile. The caption reads: “I chipped my tooth.”
Bieber may have a few more social media followers than the average person, but his dental problem is not unique. Sports injuries, mishaps at home, playground accidents and auto collisions are among the more common causes of dental trauma.
Some dental problems need to be treated as soon as possible, while others can wait a few days. Do you know which is which? Here are some basic guidelines:
A tooth that’s knocked out needs attention right away. First, try and locate the missing tooth and gently clean it with water — but avoid holding the tooth’s roots. Next, grasp the crown of the tooth and place it back in the socket facing the correct way. If that isn’t possible, place it between the cheek and gum, in a plastic bag with the patient’s saliva or a special tooth preservative, or in a glass of cold milk. Then rush to the dental office or emergency room right away. For the best chance of saving the tooth, it should be treated within five minutes.
If a tooth is loosened or displaced (pushed sideways, deeper into or out of its socket), it’s best to seek dental treatment within 6 hours. A complete examination will be needed to find out exactly what’s wrong and how best to treat it. Loosened or displaced teeth may be splinted to give them stability while they heal. In some situations, a root canal may be necessary to save the tooth.
Broken or fractured (cracked) teeth should receive treatment within 12 hours. If the injury extends into the tooth’s inner pulp tissue, root canal treatment will be needed. Depending on the severity of the injury, the tooth may need a crown (cap) to restore its function and appearance. If pieces of the tooth have been recovered, bring them with you to the office.
Chipped teeth are among the most common dental injuries, and can generally be restored successfully. Minor chips or rough edges can be polished off with a dental instrument. Teeth with slightly larger chips can often be restored via cosmetic bonding with tooth-colored resins. When more of the tooth structure is missing, the best solution may be porcelain veneers or crowns. These procedures can generally be accomplished at a scheduled office visit. However, if the tooth is painful, sensitive to heat or cold or producing other symptoms, don’t wait for an appointment — seek help right away.
Justin Bieber earned lots of “likes” by sharing a picture from the dental office. But maybe the take-home from his post is this: If you have a dental injury, be sure to get treatment when it’s needed. The ability to restore a damaged smile is one of the best things about modern dentistry.
If you have questions about dental injury, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Repairing Chipped Teeth” and “Porcelain Crowns & Veneers.”
They seemingly pop up out of the blue inside your mouth: tiny sores that are sometimes painful — and always annoying. Then, in about a week to ten days these small, irritating lesions are gone.
They're known as canker sores: the most common break out in the linings of the mouth, including the cheeks, lips, under the tongue or even the back of the throat. Medically known as aphthous ulcers, you'll recognize these round lesions by their yellow-gray center surrounded by a red “halo.”
You might feel a tingling sensation a couple of days before an outbreak. Once they appear they usually last a week to ten days; during that time they can cause discomfort especially while eating or drinking.
We don't know fully what causes canker sores, but it's believed they're related to abnormalities in the immune system, the processes in the body that fight infection and disease. High stress or anxiety and certain acidic or spicy foods like citrus fruit or tomato sauce also seem to trigger them.
Most people experience canker sores that range in intensity from slight discomfort to sometimes severe pain. But about 20-25% of people, mostly women, have an acute form known as recurrent aphthous stomatitis (RAS). Thought to be hereditary, RAS produces clusters of ulcers that are almost always painful, and which come and go on a regular basis.
Our main treatment goal with canker sores is to decrease discomfort while the outbreak runs its course and promote rapid healing. There are over-the-counter ointments that often prove effective. For more resistant symptoms we can also prescribe topical or injectable steroids or other medications.
Canker sores are rarely concerning as a significant health issue. You should, however, take an outbreak seriously if it hasn't healed within two weeks, if the outbreaks seem to be increasing in frequency or severity, or you're never without a sore in your mouth. In these cases, we may need to take a tissue sample of the lesion to biopsy for signs of cancer, pre-cancer or some other skin disease.
More than likely, though, the canker sore will be benign albeit annoying. With effective treatment, though, you can get through the outbreak with only a minimal amount of discomfort.
If you would like more information on treating canker sores, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Mouth Sores.”
Although normally benign, a cold sore outbreak can be irritating and embarrassing. Understanding why they occur is the first step to minimizing outbreaks.
The typical cold sore (also known as a fever blister) is caused by the Herpes Simplex Virus (HSV) Type I, medically known as “Herpes Labialis” because it occurs on or around the lips. This virus is not to be confused with HSV Type II, which causes a genital infection. Unlike most viruses, HSV Type I can cause a recurring sore outbreak in certain people. Most viruses tend to occur only once because the body produces anti-bodies to prevent further attack; it’s believed HSV Type I, however, can shield itself from these defenses by hiding in the body’s nerve roots.
These cold sore outbreaks often occur during periods of high stress, overexposure to sunlight or injuries to the lip. Initially you may have an itch or slight burning around the mouth that escalates into more severe itching, redness, swelling and blistering. The sores will break out for about a week to ten days and then scab over and eventually heal (unless they become infected, in which case the healing process may go longer). You’re contagious between the first symptoms and healing, and so can spread the virus to other people.
In recent years, anti-viral prescription medications have been developed that can effectively prevent HSV outbreaks, or at least reduce the healing time after an occurrence. The most common of these are acyclovir and valcyclovir, proven effective with only a few possible mild side effects. They can be taken routinely by people with recurring cold sores to suppress regular outbreaks.
While HSV Type I cold sores are more an aggravation than a health danger, it’s still important for you to see us initially for an examination if you encounter an outbreak. It’s possible for a more serious condition to masquerade as a cold sore or blister. A visit to us may also get you on the right track to reducing the frequency of outbreaks, as well as minimizing discomfort when they do occur.
