Utensils and Misaligned Teeth: Are they Connected?

Crooked teeth are a considerable concern for many people. Otherwise, providers People with Crooked Teethof Invisalign in Solihull and elsewhere would likely close shop. The value of Invisalign (not to mention the overall importance of orthodontics), however, is more than just aesthetics. Crooked teeth are vulnerable to decay because they’re tough to clean, for one.

While orthodontics can certainly remedy the situation, it’s still a curious thought why humans tend to have misaligned teeth, to begin with. Many experts believe it might be due to the use of eating utensils, specifically the fork. The oral problem in question is the overbite.

Historical Bits

Bee Wilson, author of the book Consider the Fork, writes about the evolution of cooking and eating technology. She cites several bits of evidence which may explain why many people have an overbite. Archaeological evidence suggests that until roughly 250 years ago, humans had an edge-to-edge bite. This means that human teeth are almost perfectly aligned. The top layer touches the bottom layer almost completely, without deviation.

Wilson also notes that there are instances of a sudden change in the alignment of the jaw—an overbite. This describes when the top layer of the teeth overlaps the bottom layer, in various degrees of severity. Wilson notes the research by American anthropologist C. Loring Brace, which states that cutlery is the main culprit of overbites.

This is probably evolution at work, and in plain sight. It’s been discussed many times how the human body differs, compared to days of yore. Various changes in diet, lifestyle, personal hygiene, and other factors involving modern human living have caused physical changes. Perhaps the development of the overbite is an evolutionary adaptation mechanic. Constant use of solid tools probably ‘forced’ the human jaw and mouth to evolve and work with the tool, in order to maintain efficiency and comfort.

It makes sense to assume as much. Furthermore, if the overbite is a problem, it is something that can be corrected. Orthodontic appliances are only getting better, with Invisalign being a great example. Still, it’s an interesting thought to see the physical changes the human body has experienced, and the ones that are to come in several hundred years’ time.

How to Protect your MIG Welders from Risks

MIG WeldersWhether you are a manufacturer of heavy equipment employing several welders or a startup automotive shop, chances are you use the MIG or metal inert gas welder. This specific kind of welder is among the most versatile welder types since they could work with various materials and applications.

However, you should bear in mind the risks your welders expose themselves to while at work. You can employ safety mechanisms, like the use of downdraft tables or aluminum dust collectors, and do extensive orientation in your workplace on the importance of safety.

Here are some of the potential hazards of MIG welding.

Respiratory Health Dangers

MIG welding contributes to various respiratory illnesses. The metal welded, the filler utilized, and anything on the object’s surface worked on, including paint, undergo a vaporization process. This, in turn, produces toxic fumes and smoke your welders can inhale.

Likewise, inert gases utilized for shielding the electric arc light generated by the welding equipment could build up in the workspace and displace oxygen. Also, this process could also produce carbon monoxide at potentially dangerous levels, all of which can affect your respiratory health.

Fire Hazards

MIG welding is just among the many “hot works” in the manufacturing industry that involves the active use of many potential sources of ignition.

If the welding station already has breathable air and a potential ignition source, you should take great care to eliminate or significantly reduce the presence of combustible materials.

Electric Shocks

This is among the most immediate and serious risks MIG welders face every single day. Contact with electrically hot metal components could result in injury or worse, death, due to the electric shock itself or a fall or slip resulting from the electrocution.

Skin and Eye Burns

Anyone in the welding zone is in danger of burning the skin and eyes if they look directly at the hot, bright welding arc. In addition, melted metal drops sprayed and splashed in the welding zone could easily burn the skin.

Put simply, you hold the key to keeping your MIG welders and other workers safe in the workplace. Put safety measures in place, and always remind your welders on the importance of being safe.
