Heart Disease

Poor dental hygiene can cause a host of problems outside your mouth-including your heart. Medical research has uncovered a definitive link between heart disease and certain kinds of oral infections such as periodontal disease. Some have even suggested that gum disease may be as dangerous as or more dangerous than other factors such as tobacco use. A condition called chronic periodontitis, or persistent gum disease, has been linked to cardiovascular problems by medical researchers.

In short, infections and harmful bacteria in your mouth can spread through the bloodstream to your liver, which produces harmful proteins that can lead to systemic cardiac problems. That's why it is critical to practice good oral hygiene to keep infections at bay-this includes a daily regimen of brushing, flossing and rinsing.


Antibiotic Prophylaxis

In some cases, patients with compromised immune systems or who fear an infection from a dental procedure may take antibiotics before visiting the dentist.

It is possible for bacteria from your mouth to enter your bloodstream during a dental procedure in which tissues are cut or bleeding occurs. A healthy immune system will normally fight such bacteria before they result in an infection. However, certain cardiovascular conditions in patients with weakened hearts could be at risk for an infection or heart muscle inflammation (bacterial endocarditis) resulting from a dental procedure.

Patients with heart conditions (including weakened heart valves) are strongly advised to inform our office before undergoing any dental procedure. The proper antibiotic will prevent any unnecessary complications.


Dentistry Health Care That Works: Tobacco

The American Dental Association has long been a leader in the battle against tobacco-related disease, working to educate the public about the dangers inherent in tobacco use and encouraging dentists to help their patients break the cycle of addiction. The Association has continually strengthened and updated its tobacco policies as new scientific information has become available.

Smoking and Implants

Recent studies have shown that there is a direct link between oral tissue and bones loss and smoking. Tooth loss and edentulism are more common in smokers than in non-smokers. In addition, people who smoke are more likely to develop severe periodontal disease.

The formation of deep mucosal pockets with inflammation of the peri-implant mucosa around dental implants is called peri-implantitis. Smokers treated with dental implants have a greater risk of developing peri-implantitis. This condition can lead to increased resorption of peri-implant bone. If left untreated, peri-implantitis can lead to implant failure. In a recent international study, smokers showed a higher score in bleeding index with greater peri-implant pocket depth and radiographically discernible bone resorption around the implant, particularly in the maxilla.

Many studies have shown that smoking can lead to higher rates of dental implant failure. In general, smoking cessation usually leads to improved periodontal health and a patient’s chance for successful implant acceptance.

In the future, could small cavities be detected early and filled without anesthesia, and with only the minimum removal of tooth material? Will routine dental procedures be performed with patients noticing no vibration or pressure? Will the piercing whine of a dental drill be a sound that's heard in dental offices no more? The answer may well be yes — in fact, it's happening right now with air abrasion technology.

The air abrasion instrument is a hand-held tool that dentists use for a variety of purposes. A bit like a mini-sandblaster, it uses compressed air (or another gas) to produce a fine stream of abrasive particles that can be precisely aimed. The small, high-speed particles (often silica or aluminum oxide) remove tiny bits of material in the decayed portion of the tooth; the debris is then whisked away through a suction tube.

Sound futuristic? It is, but it's not exactly new: Air abrasion instruments were first developed in the 1940's, but recent advances in high-volume suction and improved dental restoration materials have given the process a renewed appeal. Some of the uses for air abrasion tools include: removing dental caries (cavities) and filling them with composite (tooth-colored) material; preparing teeth for bonding, veneering or other procedures; and removing stains or even repairing small defects in teeth.

How It Works

The tiny abrasive particles (.002” or less in diameter) remove only minute amounts of tooth structure, making a drill seem coarse by comparison. The air pressure, flow rate, nozzle diameter, and other settings on the instrument can be accurately controlled to produce the precise amount of abrasion needed. The result is a minimally-invasive method of removing decayed or unwanted tooth material.

Even though powerful suction is used to remove spent abrasive and debris, it's still necessary for everyone to wear protective eyewear as a precaution. A rubber dam (shield) is also generally used to keep abrasive particles from affecting other teeth or getting into areas of the mouth where they don't belong. Nearby teeth and gums can also be coated with a protective resin if needed.

Advantages of Air Abrasion

Because it doesn't require a whirring drill, air abrasion generates no pressure or vibration, and makes very little noise. It can eliminate the need for anesthesia, especially if the cavity isn't deep. It reduces the chance of damaging the tooth during a procedure, and it leaves more healthy tooth material behind. This makes it ideal for children, or others who are sensitive to dental discomfort. In fact, it's perfect for treating tiny cavities that have been detected by laser diagnosis (cavities that aren't big enough to be seen on an X-ray), and sealing them up before they become bigger problems.

Minimally-invasive procedures are where air abrasion truly shines. Because it's a relatively fine-scale instrument, it isn't suitable for treating deep cavities or removing old metal fillings. However, as a high-tech tool for performing many preventive and restorative dental procedures, it offers some unique benefits to both dentist and patient. And some day, it just might make the dental drill obsolete.
