Alcohol containing mouthwash and risk of Oral Cancer and tooth enamel loss

Mouthwash

At Arrawatta Dental Centre we have never been big proponents of over the counter mouthwashes since they contain alcohol as their main ingredient. There is as much as 26% alcohol content which equates to a 52 proof alcoholic drink.  Most people drink wine and beer as their alcoholic drink of choice and they rarely reach alcohol content of 14% and no one keeps their drink in their mouth for 1 minute or more before swallowing it.  Herein lays the problem with mouthwashes with high alcohol content that are in contact with the mouth for long periods of time before spitting them out.  In a recent finding that was published in the Dental Journal of Australia they showed that these mouthwashes can be dangerous and poses a risk factor linked to the development of oral cancer. Long term use has shown microscopic and macroscopic changes to the tissues.  If you’re a smoker the effects are magnified because studies have shown that alcohol enhances the penetration of tobacco associated carcinogens.  Most people use these products to eliminate bad breath and with smokers this can be deadly.

In another study researchers found that these mouthwashes are quite acidic anywhere from 4.3 to 5.0 and cause erosion of dental enamel and can eventually cause sensitivity of the teeth.  Neutral ph is 7.0 similar to the ph of saliva.  This means these mouthrinses are quite acidic.  If your enamel is thin or thinning chance of getting tooth sensitivity increases with the use of these mouthwashes.

People tend to assume if a product appears in the supermarket shelves it must be safe. Time and again that assumption has proven incorrect.

Invisalign is really a program that’s getting used to exchange the actual aggravations of steel braces for your teeth with a plastic material that invisibly lines up one’s teeth. Which means that aside from doing all of the comprehensive straightening that regular braces for your teeth used to for any patient’s tooth, Invisalign braces braces additionally do it in a way that is in fact practically invisible towards the eye?

Interview: “A bite inflicted by a human can have serious health implications”

 

by Daniel Zimmermann, DTI

In Brazil, 32 football teams from around the globe are competing for the World Cup trophy this year. Dental Tribune ONLINE had the opportunity to speak with Dr Dietrich Fischer-Brooks from Germany, a former FIFA-appointed dentist who also provides dental care to the players in German Bundesliga club Eintracht Frankfurt, about the oral health of football players and why the bite inflicted by Uruguay superstar Luis Suárez during his team’s match against Italy could have rather serious implications for his opponent.

Dental Tribune ONLINE: Dr Fischer-Brooks, the biting incident involving Luis Suárez has made headlines during this year’s World Cup tournament. In addition to a long-term ban, could this incident have any implications for his oral health?
Dr Dieter Fischer-Brooks: Only for his Italian opponent, Giorgio Chiellini. A wide variety of harmful bacteria live in the oral cavity and a bite inflicted by a human can have serious health implications. I know of some severe infections that have resulted from such bites.

Suárez appeared to have suffered from pain directly after the incident. Was this real or just an act?
I believe that this was just an act. Upon realising that he had been bitten, the Italian would likely have struck out at Suárez, but whether he really hit Suárez is subject to speculation.

Would you have recommended that Suárez visit a dentist after the game?
Only if he had really been struck on the mouth. Shortly afterwards, I saw him giving an interview, however, which indicates that it could not have been that bad.

Are elbow impacts a frequent cause of dental injuries in football?
Definitely. Many of the players I treat here in Frankfurt on a regular basis have sustained injuries to their anterior teeth at some time in their career. Therefore, many players wear mouth guards while playing. One often sees them during post-match interviews.

Do players have to undergo dental check-ups during a tournament like the World Cup or is oral health considered their personal responsibility?
This really depends on the professionalism of the staff. As a principle, players should be checked in advance of the tournament for any signs of infections in the mouth, or in the jaw and face area.

Cases of players suffering sudden cardiac death on the pitch are not uncommon. In many of these cases, the cause was a serious infection, which may have resulted from dental problems, including infected third molars, severe periodontitis or infections in endodontically treated teeth, to name a few.

What impact can these problems have on the health or the performance of players?
Bacteria migration from anywhere in the human body can affect the heart valves. Moreover, it can lead to inflammation in joints like the knee. I remember a case here in Frankfurt in which a player, who also played for the Czech national team, was unable to wear football shoes for months owing to a fistula on his small toe. We were finally able to attribute this to an infected third molar. When we removed the molar, the fistula disappeared within days, allowing the player to resume training.

Team physicians often struggle with these symptoms because they are not able or trained to recognise such associations. This example demonstrates clearly that bacteria in the mouth can migrate to distant parts of the body. In most cases, the heart primarily is affected.

Football players have celebrity status and pay significant attention to their body image. How important are good teeth in this regard?
Straight and attractive teeth have become a symbol of success. I have to say, however, that some players have developed a downright tooth fetish, as they visit me every two or three months to have their teeth checked. In many foreign players, particularly those from Eastern Europe, it is evident that they did not receive adequate dental care while they were children. Consequently, I usually have to perform extensive dental treatment on such players.

During the 2006 tournament in Germany, you were responsible for dental treatment for the teams from England and Saudi Arabia. Did you observe any differences with regard to their oral health?
There are significant inequalities internationally. Dental care (similar to general health care) in England, for example, is not the best. This is evident in the poor state of dentition, including defective fillings and other signs of second-rate dentistry. High-quality oral health care as practised in Germany or Switzerland, for example, is not common.

Owing to your work, do you pay more attention to the teeth of footballers, and are there any players whose teeth have impressed you lately?
I am really fascinated by James Rodríguez from Columbia. This young player has very attractive teeth. At the moment, I have also been paying attention to the teeth clenching that one commonly sees in players during interviews. Aesthetics is one thing, but there are also medical aspects to this.

Increased incidence of decay among children

kidsPIC B

Many of us are used to routinely taking our children to the dentist and not being overly concerned about the dentist finding rampant cavities. The trend of decreasing tooth decay among children and young adults has been with us since the late 1960s.
Now, however, this trend seems to be coming to an end and is creating new cause for concern. According to the largest study on dental health in the last 25 years, tooth decay is on the increase in babies and children age 6 months to 5 years of age. The proportion of children with cavities has risen from 24 percent 20 years ago to 33 percent.
Rotten baby teeth cause the child discomfort and need to be filled. If the decay is extensive, a crown or extraction becomes necessary. Decayed primary teeth lead to higher rates of decay in permanent teeth. The early loss or destruction of baby teeth may lead to crowding of adult teeth.
Experts are concerned and agree that diet is a significant component of the marked increase. The same factors contributing to the obesity epidemic can also contribute to tooth decay.

Parents are giving their children more processed snack foods than in the past, as well as juice boxes and other sweetened drinks. Some health-conscious parents give their children bottled water, not realizing that tap water is fluoridated and serves to preserve the integrity of dental enamel.
Another reason for the increase in incidence of decay may be inadequate dental care. Young children cannot manage brushing their teeth properly, especially the back teeth.
What can you do? Good care begins in pregnancy. Your baby’s dentition starts developing in the 12th week of pregnancy. Observe the basic rules of healthy eating: fruits, vegetables, healthy oils, adequate fiber.
Once your baby is born, do not put your baby to sleep with a bottle in his or her mouth, as the sugars from the juice or milk remain on the teeth for hours and damage the enamel.
Running a damp washcloth over your baby’s gums following feedings can prevent build-up of damaging bacteria.
Young children need their teeth brushed, especially their back teeth, until they can tie their own shoes. Take your child to see the dentist at around age 3. The dentist can perform a modified exam while your child sits in your lap. Such visits can help in the early detection of decay and also help kids become accustomed to visiting the dentist and have no anxiety associated with these visits as they grow older.
At around this age, when all of your child’s teeth have come in, your dentist may start applying topical fluoride. Fluoride hardens the tooth enamel and helps in preventing the quickly progressing tooth decay.
Although dental research has resulted in increasingly sophisticated preventive techniques, a dentist’s care is only part of the equation. The other components of a healthy mouth are good oral health habits (brushing and flossing) and what goes on the teeth — also known as nutritional habits. Limit the number of times during the day that your child has juice or soda. It is the repeated “sugar bath” that attacks the enamel and makes the teeth prone to decay. Increase the proportion of tap water, which contains fluoride (in most communities), in your child’s diet.
Many parents give their children nutrition bars and “power” bars as a quick and convenient energy booster. Unfortunately, these contain high amounts of carbohydrates and sugar which stick to the teeth and help dissolve the protective enamel of the teeth. Instead, aim for natural snacks such as nuts, carrots, fresh fruit, popcorn, whole-grain pretzels, cheese and such.
You will find your child fit and healthy, and seeing your child smile showing his healthy pearly whites will sweeten your day.

METAL AMALGAM RESTORATIONS: A DANGER?

One of the most frequently asked question in our practice relates to the question of silver amalgam as a restorative material. Should it still be used? Should all my existing amalgam restorations be replaced? Are my existing filling safe and is it affecting my general health?

Personally, Silver Amalgam restorations have very limited use in our practice.  Not only do traditional silver amalgam restorations appear unaesthetic, they also eventually damage teeth that they are supposed to protect. Metal fillings expands and contracts with temperature changes. These movements, combined with the wedging action of the unbonded metal restoration places internal pressure to the remaining tooth structure eventually resulting in cracks and breakages.

I believe it is simply an inferior material to a well-placed bonded tooth coloured restorations in the form of direct composite or indirect ceramic restorations. Not only are these modern materials as durable (if not more durable) than the traditional metal amalgam fillings, but they are also more natural in appearance.

Silver amalgam starts off as a fine metal powder composed of silver, copper, and other metals which is mixed with a droplet of mercury. This forms a sort of paste which quickly hardens into a solid amalgam. Once hardened, the components are chemically locked together.

The concern is about the possibility of mercury release from those fillings in your mouth over time. There has been a LOT of controversy about this over literally 150 years. To date, no recognized scientific entity has determined that there are any negative health issues with amalgam fillings. And, I am inclined (so far) to believe that there are no real health issues with the mercury that is locked up in amalgam fillings. However, I am open to REAL scientific evidence to the contrary.

A far bigger source of mercury in our environment is from coal-burning electric plants that put tons of mercury in the atmosphere. That mercury ends up in the ground and water. You’ve probably heard about mercury concerns when it comes to eating fish.

Oddly enough, the government or regulatory bodies have deemed scrap amalgam as a hazardous waste. Meanwhile, some other government entities assure us it is safe for use in dentistry. So, it’s against the law to put it in the garbage or landfills in some places. But, it’s safe to put in your mouth?

Another thing that will make you go, “Hmmmm” is that the goverment in the U.S. is banning incandescent (traditional) light bulbs in favor of the so-called “green” compact fluorescent bulbs. Those are the “curly-cue” bulbs. And, they contain mercury. The EPA protocol, should one of these bulbs break, is extensive due to the mercury content within the bulb.This is a clear illustration of the contradictory agendas we see, and it should definitely make one question the “lines” presented by differing bodies.

Some countries around the world have restricted the use of amalgam. And, every so often, the notion of banning it in comes up. And, so here we are again. I believe it will be banned eventually – possibly for the wrong reasons – But, it will be banned some day.

Although there are biomechanics advantages in electively replacing metal amalgam restorations to prevent fractures of the supporting tooth structure, I do not advocate the wholesale replacement of amalgams in order to prevent or treat any medical condition. And, I won’t until credible scientific evidence supports the notion. However, I do understand that some patients do not want them in their mouths for a variety of reasons, including cosmetic concerns. “Silver” fillings are really BLACK fillings.  And, who wants that?
