DontIgnoreToothPain-YouMayNeedaRootCanal

Tooth decay is one of the most common diseases in the world, nearly as prevalent as the common cold. It’s also one of the two major dental diseases—the other being periodontal (gum) disease—most responsible for tooth and bone loss.

Tooth decay begins with high levels of acid, the byproduct of oral bacteria feeding on food remnants like sugar. Acid can erode tooth enamel, leading to a cavity that will require removal of decayed material around it and then a filling.

Sometimes, though, decay can spread deeper into the tooth reaching all the way to its core: the pulp with its bundle of nerves and blood vessels. From there it can travel through the root canals to the bone. The continuing damage could eventually lead to the loss of the infected tooth.

If decay reaches the tooth interior, the best course of action is usually a root canal treatment. In this procedure we access the pulp through the crown, the visible part of the tooth, to remove all of the diseased and dead tissue in the pulp chamber.

We then reshape it and the root canals to receive a filling. The filling is normally a substance called gutta percha that’s easily manipulated to conform to the shape of the root canals and pulp chamber. After filling we seal the access hole and later cap the tooth with a crown to protect it from re-infection.

Root canal treatments have literally saved millions of teeth. Unfortunately, they’ve gained an undeserved reputation for pain. But root canals don’t cause pain—they relieve the pain caused by tooth decay. More importantly, your tooth can gain a new lease on life.

But we’ll need to act promptly. If you experience any kind of tooth pain (even if it goes away) you should see us as soon as possible for an examination. Depending on the level of decay and the type of tooth involved, we may be able to perform the procedure in our office. Some cases, though, may have complications that require the skills, procedures and equipment of an endodontist, a specialist in root canal treatment.

So, don’t delay and allow tooth decay to go too far. Your tooth’s survival could hang in the balance.

CouldYourMetalAllergyKeepYouFromObtainingDentalImplants

Dental implants are today’s closest restorative facsimile to natural teeth. And they’re versatile: not only can they replace single teeth but they can also support bridges or dentures.

But since one of their crucial components is made of metal, are you out of luck obtaining this state-of-the-art dental restoration if you have a metal allergy?

The answer is: probably not—it’s rare for implants to cause an allergic reaction. Still, metal allergies can be a potential problem within your mouth as with other areas of health.

An allergy originates from the body’s necessary response to potentially harmful microorganisms or substances. Sometimes, however, this response becomes chronic and exaggerated, creating an allergy. People can have allergies to nearly anything with responses ranging from a minor rash to a potentially life-threatening multi-organ system shutdown (anaphylactic shock).

A small number of people have allergies to particular metals. One of the most common is nickel, which affects an estimated 17% of women and 3% of men; cobalt and chromium are also known to cause allergies. Consumer exposure, particularly metal contact with the skin through jewelry or clothing, is the most prevalent, but not the most concerning. That’s reserved for metal allergies related to medical devices like coronary stents or hip and knee prostheses. And in dentistry, there are rare occasions of inflammation or rashes from metal amalgam fillings.

Which brings us to dental implants: the main metal post that’s inserted into the jawbone is usually made of titanium. It’s the metal of choice for two reasons: it’s bio-compatible, meaning the body normally accepts its presence; and it’s osteophilic, which means bone cells readily grow and adhere to it, a major reason for implant durability.

While it’s possible for someone to have an allergy and subsequent reaction to implants with titanium, the occurrences appear to be extremely low. In one study of 1,500 patients, titanium allergies were estimated to be a factor in implant failures in less than 1% of those studied.

Even so, if you have known metal allergies you should make sure your dentist knows. Being aware of all the facts will help them recommend the best tooth replacement choice for you—and hopefully it will be dental implants.

PromptTreatmentforGumDiseaseCouldUltimatelySaveYourTeeth

Your smile isn’t the same without healthy gums—neither are your teeth, for that matter. So, maintaining your gums by protecting them from periodontal (gum) disease is a top priority.

Gum disease is caused by bacterial plaque, a thin biofilm that collects on teeth and is not removed due to poor oral hygiene practices. Infected gums become chronically inflamed and begin to weaken, ultimately losing their firm attachment to the teeth. This can result in increasing voids called periodontal pockets that fill with infection. The gums can also shrink back (recede), exposing the tooth roots to further infection.

Although gum disease treatment techniques vary, the overall goal is the same: remove the bacterial plaque fueling the infection. This most often involves a procedure called scaling with special hand instruments to manually remove plaque and calculus (tartar). If the infection has spread below the gum line we may need to use a procedure called root planing in which we scrape or “plane” plaque and calculus from the root surfaces.

As we remove plaque, the gums become less inflamed. As the inflammation subsides we often discover more plaque and calculus, requiring more treatment sessions. Hopefully, our efforts bring the disease under control and restorative healing to the gums.

But while gum tissue can regenerate on its own, it may need some assistance if the recession was severe. This assistance can be provided through surgical procedures that graft donor tissues to the recession site. There are a number of microsurgical approaches that are all quite intricate to perform, and will usually require a periodontist (a specialist in gum structures) to achieve the most functional and attractive result.

While we have the advanced techniques and equipment to treat and repair gum disease damage, the best approach is to try to prevent the disease from occurring at all. Prevention begins with daily brushing and flossing, and continues with regular dental cleanings and checkups.

And if you do notice potential signs of gum disease like swollen, reddened or bleeding gums, call us promptly for an examination. The sooner we diagnose and begin treatment the less damage this progressive disease can do to your gums—and your smile.
