Infant Formulas Have Fluoride; Avoid Mixing with Fluoridated Water

All infant formulas, either concentrated or ready-to-feed, already contain some fluoride and, when routinely mixed with fluoridated water, increase the risk of dental fluorosis (discolored teeth), according to Dr. Howard Koh, Assistant Secretary for Health, U.S. Department
of Health and Human Services (HHS) in a video commentary published on medscape.com. (1)

Fluoride, added to water supplies ostensibly to reduce tooth decay, is also in food, beverages, dental products, medicines, and anesthesia and inhaled from ocean mist and air pollution. As a result, more than 41% of adolescents are fluoride-overdosed and afflicted with dental fluorosis—more than 3% of it is moderate to severe (brown stains and pitting), according to the Centers for Disease Control.

Second-hand Smoke Could be Related to Cavities

A new study indicates that second-hand smoke may have an effect on cavities.

People who inhale second-hand smoke may be at a higher risk for cavities, according to the study, which was led by Dr. Taru Kinnunen, the director of the Tobacco Dependence Treatment and Research Program at the Harvard School of Dental Medicine.

Dr. Kinnunen mentioned this study when speaking at the University of Manitoba’s dental faculty annual research day. He said that second-hand smoke caused the risk of cavities to rise because smoke still entered the naval cavities and the mouth. As a result, the saliva was impacted.

Hygienists Open Business, Save Canadians Money

Dental hygienists in Alberta are trying to make the best of a bad economy.

Hygienists in the Canadian province have opened up their own businesses, enabling patients to get dental services for a fraction of the cost of a visit to the dentist. These hygienists are legally able to do this because of a law that passed in Alberta in 2006. The Alberta Health Professions Act makes it possible for hygienists to open a business and provide basic treatments and services at lower costs than dentists.

Tracey Cote, the president of the Association of Private Practice Dental Hygienists of Alberta, claims that the hygienist offices are ideal for families looking to save money. These hygienists offer cleaning treatments and dental x-rays.

Researchers Unveil Protein that Could Increase Implant Success

Georgia Health Sciences University researchers have come up with a bone-creating protein that could be revolutionary for implants. The protein could increase the rate of success for implants because it would make thin bones stronger.

Dental implants can’t function properly if the bone the implants are attached to is too thin.

The problem for dentists and implant specialists is that bone thinning is generally associated with tooth loss. Bone grafts are then needed in order for implants to be placed successfully into one’s mouth. But the problem is that more surgery is then needed.

Zinc May be Hazardous to Dental Patients

A study done by Amar Patel, DDS, and his colleagues at the University of Maryland Dental school claim that zinc, which is an ingredient in many dental products, may be hazardous. The study appears in the March/April issue of the journal of General Dentistry.

Zinc is good for the body when the body is exposed to it in small doses, however, too much is potentially toxic. Some patients could have neurological problems from zinc exposure, and others could experience nausea, a stomachache or mouth irritation.
