Human beings have known for millennia the importance of keeping teeth clean. Although we've only come to more fully understand dental plaque's role in dental disease in the last century, our ancestors seemed to know instinctively this gritty biofilm on teeth had to go.
People from the past once used a variety of substances like ground oyster shells or leftover fire ashes to remove plaque from their teeth. Today, most of the world has replaced these substances with toothpaste, a mainstay of daily oral hygiene.
So, why is toothpaste better than other substances used in the ancient past? Besides the many other ingredients found in the typical tube of toothpaste, here are the top 3 that make it the ultimate tooth cleaner.
Abrasives. While your toothbrush does most of the mechanical work loosening plaque, toothpaste has ingredients called abrasives that give an added boost to your brushing action. The ideal abrasive is strong enough to remove plaque, but not enough to damage tooth enamel. If you look at your toothpaste's ingredient list, you'll probably see an abrasive like hydrated silica (made from sand), hydrated alumina, calcium carbonate or dicalcium phosphates.
Detergents. Your toothpaste's foaming action is a sign of a detergent, which helps loosen and break down non-soluble (not dissolvable with plain water) food substances. While similar to what you may use to wash your clothes or dishes, toothpaste detergents are much milder, the most common being sodium lauryl sulfate found in many cosmetic items. If you have frequent canker sores, though, sodium lauryl sulfate can cause irritation, so look for a toothpaste with a different detergent.
Fluoride. The enamel strengthening power of fluoride was one of the greatest discoveries in dental care history. Although not all toothpastes contain it, choosing one with fluoride can improve your enamel health and help protect you from tooth decay.
These and other ingredients like binders, preservatives and flavorings, all go in to make toothpaste the teeth-cleaning, disease-fighting product we've all come to depend upon. Used as part of daily oral hygiene, toothpaste can help brighten and freshen your smile, and keep your teeth and gums healthy.

Radiographic (x-ray) images are an indispensible diagnostic tool in dentistry. One of the most routine and useful types of x-rays dentists take is the so-called bitewing. Here are some things you may want to know about this common diagnostic procedure.
What are bitewing x-rays?
Bitewings reveal the presence and extent of decay in the back teeth, specifically in areas where adjacent teeth touch each other. Unlike other areas of the teeth, these contacting surfaces between adjacent teeth can’t be examined visually. Bitewings can also show areas of bone loss around teeth — a sign of periodontal disease; however, they are not taken for that purpose because bitewings will not show the complete root surface that is surrounded by bone.
Why are they called that?
The name “bitewing” refers to how the film — or sensor, in the case of a digital x-ray — is positioned in the mouth: The patient bites down on a little tab or wing that holds the apparatus in place.
How often do I need them?
This is determined on a case-by-case basis, with the goal of not exposing you to any more radiation than necessary — even the minimal amount found in a series of bitewing x-rays. Your individual susceptibility to caries (tooth decay) and personal dental history will play a major role in determining how frequently you need radiographic examination — and, for that matter, how often you need to come in for routine cleanings and exams.
Are they safe?
The safety of bitewing x-rays is best illustrated with a comparison to the regular daily radiation exposure we get every day from environmental sources, which is about 0.01 millisieverts — the unit of measure we use for radiation. A series of 4 bitewing x-rays exposes you to 0.004 millisieverts of radiation — less than half of the daily exposure. Undetected tooth decay, which can spread quickly through the softer inner layers of teeth, is considered much more dangerous!
If a bitewing x-ray shows that there is tooth decay, what happens next?
If the cavity is very small, we may be able to treat it during the same appointment. If not, we will make a separate appointment to make sure it is taken care of promptly. The sooner tooth decay is treated, the better!
Periodontal (gum) disease is mainly caused by bacterial plaque built up on tooth surfaces due to ineffective oral hygiene. For most cases, treatment that includes plaque and calculus (tartar or calcified plaque) removal and renewed daily hygiene is highly effective in stopping the disease and restoring health to affected gum tissues.
However, you might have additional health factors that may make it more difficult to bring the disease under control. If your case is extreme, even the most in-depth treatment may only buy time before some or all of your teeth are eventually lost.
Genetics. Because of your genetic makeup, you could have a low resistance to gum disease and are more susceptible to it than other people. Additionally, if you have thin gum tissues, also an inherited trait, you could be more prone to receding gums as a result of gum disease.
Certain bacteria. Our mouths are home to millions of bacteria derived from hundreds of strains, of which only a few are responsible for gum disease. It’s possible your body’s immune system may find it difficult to control a particular disease-causing strain, regardless of your diligence in oral care.
Stress. Chronic stress, brought on by difficult life situations or experiences, can have a harmful effect on your body’s immune system and cause you to be more susceptible to gum disease. Studies have shown that as stress levels increase the breakdown of gum tissues (along with their detachment from teeth) may also increase.
Disease advancement. Gum disease can be an aggressive infection that can gain a foothold well before diagnosis. It’s possible, then, that by the time we begin intervention the disease has already caused a great deal of damage. While we may be able to repair much of it, it’s possible some teeth may not be salvageable.
While you can’t change genetic makeup or bacterial sensitivity, you can slow the disease progression and extend the life of your teeth with consistent daily hygiene, regular cleanings and checkups, and watching for bleeding, swollen gums and other signs of disease. Although these additional risk factors may make it difficult to save your teeth in the long-run, you may be able to gain enough time to prepare emotionally and financially for dental implants or a similar restoration.

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.

Tooth sensitivity can be disheartening: you’re always on your guard with what you eat or drink, and perhaps you’ve even given up on favorite foods or beverages.
The most common cause for this painful sensitivity is dentin exposure caused by receding gums. Dentin contains tiny open structures called tubules that transmit changes in temperature or pressure to the nerves in the pulp, which in turn signal pain to the brain. The enamel that covers the dentin, along with the gum tissues, creates a barrier between the environment and dentin to prevent it from becoming over-stimulated.
Due to such causes as aggressive over-brushing or periodontal (gum) disease, the gum tissues can recede from the teeth. This exposes portions of the dentin not covered by enamel to the effects of hot or cold. The result is an over-stimulation of the dentin when encountering normal environmental conditions.
So, what can be done to relieve painful tooth sensitivity? Here are 3 ways to stop or minimize the symptoms.
Change your brushing habits. As mentioned, brushing too hard and/or too often can contribute to gum recession. The whole purpose of brushing (and flossing) is to remove bacterial plaque that’s built up on tooth surfaces; a gentle action with a soft brush is sufficient. Anything more than two brushings a day is usually too much — you should also avoid brushing just after consuming acidic foods or liquids to give saliva time to neutralize acid and restore minerals to the enamel.
Include fluoride in your dental care. Fluoride has been proven to strengthen enamel. Be sure, then, to use toothpastes and other hygiene products that contain fluoride. With severe sensitivity you may also benefit from a fluoride varnish applied by a dentist to your teeth that not only strengthens enamel but also provides a barrier to exposed dentin.
Seek treatment for dental disease. Tooth sensitivity is often linked to tooth decay or periodontal (gum) disease. Treating dental disease may include plaque removal, gum surgery to restore receded gums, a filling to remove decay or root canal therapy when the decay gets to the tooth pulp. These treatments could all have an effect on reducing or ending your tooth sensitivity.
