More than likely your great-grandparents, grandparents and even your parents had a common dental experience: when one of their teeth developed a cavity, their dentist removed the decayed portion (and maybe a little more) through drilling and then filled the cavity. In other words, treatment was mainly reactive—fix the problem when it occurred, then fix it again if it reoccurred.
You may have had similar experiences—but the chances are good your dentist’s approach is now quite different. Today’s tooth decay treatment is much more proactive: address first the issues that cause tooth decay, and if it does occur treat it with an eye on preventing it in the future.
This approach depends on maintaining equilibrium between two sets of competing factors that influence how your teeth may encounter tooth decay. This is known as the caries balance (caries being another name for tooth decay). On one side are factors that increase the risk of decay, known by the acronym BAD: Bad Bacteria that produce acid that dissolves the minerals in tooth enamel; Absence of Saliva, the body’s natural acid neutralizer; and Dietary Habits, especially foods with added sugars that feed bacteria, and acid that further weakens enamel.
There are also factors that decrease the risk of tooth decay, known by the acronym SAFE: Saliva and Sealants, which focuses on methods to boost low salivary flow and cover chewing surfaces prone to decay with sealant materials; Antimicrobials, rinses or other substances that reduce bad bacteria populations and encourage the growth of beneficial strains; Fluoride, increased intake or topical applications of this known enamel-strengthening chemical; and Effective Diet, reducing the amount and frequency of sugary or acidic foods and replacing them with more dental-friendly choices.
In effect, we employ a variety of techniques and materials that inhibit BAD factors and support SAFE ones. The foundation for prevention, though, remains the same as it was for past family generations—practice effective oral hygiene by brushing and flossing daily and regular dental cleanings and checkups to keep bacterial plaque from accumulating and growing. Your own diligent daily care rounds out this more effective way that could change your family history of tooth decay for you and future generations.
Over the last century and a half millions of people have had a tooth cavity filled with “silver” amalgam. Perhaps you’re one of them. The use of this effective and durable filling has declined in recent years, but only because of the development of more attractive tooth-colored materials.
At the same time there’s another issue that’s been brewing in recent years about this otherwise dependable metal alloy: the inclusion of mercury in amalgam, about half of its starting mixture. Various studies have shown mercury exposure can have a cumulative toxic effect on humans. As a result, you may already be heeding warnings to limit certain seafood in your diet.
So, should you be equally concerned about amalgam fillings — even going so far as to have any existing ones removed?
Before taking such a drastic step, let’s look at the facts. To begin with, not all forms of mercury are equally toxic. The form causing the most concern is called methylmercury, a compound formed when mercury released in the environment combines with organic molecules. This is the form certain large fish like salmon and tuna ingest, which we then ingest when we eat them. Methylmercury can accumulate in the body’s tissues where at high levels it can damage various organ systems.
Dental amalgam, on the other hand, uses elemental mercury. Dentists take it in liquid form and mix it with a powder of other metals like silver, tin and copper to create a pliable paste. After it’s placed in a prepared cavity, the amalgam hardens into a compound in which the mercury interlaces with the other metals and becomes “trapped.”
Although over time the filling may emit trace amounts of mercury vapor, it’s well below harmful levels. You’re more likely to encounter “un-trapped” mercury in your diet than from a dental filling. And scores of studies over amalgam’s 150-year history have produced no demonstrable ill effects due to mercury.
Although it now competes with more attractive materials, amalgam still fills (no pun intended) a necessary role. Dentists frequently use amalgam in less visible back teeth, which encounter higher chewing pressures than front teeth. So, if you already have an amalgam filling or we recommend one to you, relax — you’re really in no danger of mercury poisoning.
For years preparing teeth for fillings or other restorations has required the use of a drill. Although quite effective in removing decayed structure and preparing the tooth for bonding, it usually requires a local anesthetic. That and the noise it generates can be unsettling for many patients.
In recent years, a different type of technique known as “air abrasion” has increased in popularity among dentists. Known also as “particle abrasion,” the technique uses a stream of fine particles to remove decayed tooth structure and is less invasive than the traditional drill. Although the technology has been around since the mid-20th Century, recent developments in suction pumps that remove much of the dust created have made it more practical. It also works well with new natural-looking bonding materials used for tooth structure replacement.
The fine particles — usually an abrasive substance like aluminum oxide — are rapidly discharged through a hand-held instrument using pressurized air aimed at affected tooth areas. Decayed teeth structure is softer than healthier tissue, which allows air abrasion to precisely remove decay while not damaging the other.
Besides removing decay or abrading the tooth for bonding, air abrasion can also be used to minimize stained areas on surface enamel and to clean blood, saliva or temporary cements from tooth surfaces during dental procedures. It’s also useful for smoothing out small defects in enamel or aiding in sealant applications.
It does, however, have a few limitations. It’s not as efficient as the traditional drill with larger cavities or for re-treating sites with metal (amalgam) fillings. Because of the fine texture of the abrasive particles, affected teeth need to be isolated within the mouth using a rubber dam or a silicone sheet. High-volume suction must be continually applied to capture the fine particles before the patient swallows them or it fills the procedure room with a fine cloud of material.
Still, while air abrasion technology is relatively new, it has clear advantages over the traditional drill in many procedures. As advances in the technology continue, air abrasion promises to offer a more comfortable and less invasive experience in dental treatment.
If you suffer from jaw pain, you may know how frustrating this condition can be and how quickly it can affect tasks like simply chewing your food. Luckily, your dentist can help you get to the root of your problem and effectively treat your condition. Find out more about jaw pain and its causes with Dr. Michael Amir and Dr. Talia Amir at Dental Planet in North Hollywood and Valley Glen, CA.
What causes jaw pain?
One of the most common causes of jaw pain is temporomandibular joint (TMJ) disorder. This condition affects the temporomandibular joints, located on either side of the jaw, and causes pain, irritation, and decreased mobility of the jaw. Other causes of jaw pain may include bruxism (teeth grinding), sinus issues, or tooth pain. Malocclusion, or bad bite, may also contribute to jaw pain.
Diagnosing Jaw Pain
When diagnosing jaw pain, your doctor will take several factors into account. It is important to have a physical examination so your doctor can determine if there are any deformities or abnormalities in your jaw causing the issues. This visit will also serve to gather your family and medical history and lifestyle choices.
Jaw Pain Treatments in North Hollywood and Valley Glen
Treating jaw pain may begin conservatively, with simple stretches and exercises and lifestyle changes such as avoiding chewing gum or decreasing stress. Hot and cold therapy, massage, or over-the-counter painkillers may also help relieve pain and irritation. Your doctor may also suggest other treatments like a mouthguard. In some cases relating to a bad bite, orthodontic care may best treat your jaw pain.

Learning you’re pregnant can be a joyous moment. But it also means life is about to change as you focus on protecting you and your child from anything that endangers your health.
Because of these new concerns you might even hesitate about receiving dental care, especially involving anesthesia. But several medical organizations representing doctors, OB-GYN physicians and dentists wholeheartedly recommend continuing regular dental visits during pregnancy.
In fact, you should continue them because you’re pregnant: physical and hormonal changes during pregnancy could increase your risk of dental disease.
For, example, your consumption of carbohydrates (like sugar) could increase, which in turn increases your risk of tooth decay. You’ll also need to be more concerned about dental plaque, a thin bacterial film on your teeth that can cause disease. Hormonal changes during pregnancy may make you more sensitive to plaque, and thus more susceptible to disease — especially periodontal (gum) disease.
In fact, a specific form of gum disease called pregnancy gingivitis affects around 40% of expectant women at some point in their pregnancy. And if you already have gum disease, pregnancy could worsen it. Left untreated the disease could develop into more severe periodontitis, which may significantly damage your teeth’s support structures far below the gum line, leading to bone loss, which could result in the eventual loss of your teeth. Daily brushing and flossing, regular cleanings and checkups and, if your dentist prescribes it, antibacterial mouth rinses can help you stay ahead of it.
But what about other procedures while you’re pregnant? It may be best to wait on elective treatments for cosmetic purposes until after the baby is born. But some situations like deep tooth decay that could require a root canal treatment may become too serious to postpone.
Fortunately, several studies have shown it’s safe for pregnant women to undergo many dental procedures including tooth fillings or extractions. And receiving local anesthesia doesn’t appear to pose a danger either.
The important thing is to remain diligent with your own personal hygiene — brushing and flossing — and making other healthy choices like eating a nutritious diet. And be sure to let your dentist know about your pregnancy to help guide your dental treatment over the next few months.
