A lip bumper is an dental appliance designed by dentists or orthodontists that has the purpose of correcting or holding into position the lower adult molar teeth and making sure that they do not come forward until the adult premolars (bicuspids) have erupted.
When a young patient is wearing a lip bumper, here are the instructions to follow:
- a lip bumper should be worn 24 hours per day with the only exception being to brush your teeth;
- the lip bumper has been placed so that it can be removed for thorough brushing; however, should it become obvious that you are not wearing the bumper 24 hours per day, it can be tied in permanently;
- When wearing the lip bumper, remember to hold your lower lip up and over it rather than letting it rest under the wire;
- when removing the lip bumper for brushing, pull it out in a straight forward motion; don’t lift up on the appliance or rock it back and forth because this might eventually loosen the bands;
- The lip bumper is a comfortable appliance and should not cause sore spots or break the skin; If you are having any problems with the it, call your dental office and they will adjust the lip bumper comfortably.
Some people think that carbonated water is as bad for your health as colas and soft drinks are. But scientific research has proved that some myths are wrong.
Facts about carbonated water:
- it does not leach calcium from your bones;
- it does not cause kidney stones;
- it mildly strips the enamel from your teeth;
- it mildly damages your stomach.

I was on Facebook today and found this illustration about a person eating a hamburger and fries, and drinking soda. That person seemed to be pregnant with Ronald McDonald himself!
The illustration might be an exaggeration, but I like the point it’s trying to make, that our body becomes the food that we eat. If we consume healthy foods, we tend to be healthier. But if we eat a lot of fast food, then we look and become unhealthy!
Last summer, I had displayed some of the artistic creations of Victor Nunes. He is a Brazilian artist who uses foods or instruments to complete his drawings, creating unique masterpieces! He had used toothbrushes as well.
But now I found something new that he designed. A drawing using dental instruments, which look more like orthodontic pliers! Above is what it looks like! And here’s the one with the toothbrushes :)
A palatal expansion is the use of an appliance placed in the mouth to make a constricted palate more wide. The following video summarizes the procedure.
A narrow palate usually allows less space for upper teeth, causing malocclusion, which is a bad relationship between teeth that gives them a misaligned appearance. Malocclusion also makes it hard to eat and brush your teeth, provoking malnutrition and other dental problems.
It is possible to expand the palate of children, teenagers, and sometimes young adults. There are many types of expanding appliances, but each usually covers the palate and holds on the upper teeth. Activation needs to be done with the expansion screw that is found in the middle of the appliance. The whole process can take several months to a year.
There was a time that people didn’t know the existence of cavities, and even less the world the microscopic bacteria. Therefore when someone had a toothache, they believed that it was caused by very little worms!
The idea now sounds very nasty, but around the 15th century, the dentist profession didn’t exist, and physicians thought that there were “tooth worms” that were causing teeth to hurt and to break apart! Those doctors prescribed a remedy for toothaches that involved lighting a candle and letting the smoke go inside your mouth and fill it. Then, you would lean your head over a warm bowl of water so the pain-causing tooth worms would fall out of your mouth and into the water.
The idea is very disturbing, even for a dentist like me. It makes me so glad that now, to treat a toothache, you can go to place and let professionals take care of you in a sterilized environment!
Human beings have 2 sets of teeth, also called dentitions. They are referred to as deciduous teeth (primary, baby or milk teeth) and permanent teeth (or adult teeth). Deciduous teeth in humans start coming out 6 to 10 months after birth, and they are eventually replaced by permanent teeth years later, usually starting around the age of 6.
Humans and all animals that have 2 consecutive sets of teeth are called diphyodont. In contrast, polyphyodont are animals who’s teeth are replaced many times. Most mammals are diphyodont, except kangaroos, elephants and manatees.
Among polyphyodont animals, for example, sharks grow a new set of teeth almost every two weeks because their teeth get worn fast and they need to be replaced. Also young and teenage crocodiles have their teeth changed with larger ones every month for reasons similar to the ones of the sharks, but this rate slows down for adult crocodiles.
Many other species of fish and reptiles are polyphyodonts. This phenomena, especially in crocodiles, is presently studied in order to research possible tooth generation in humans.
As of the day this article was published, there is no cure and no approved vaccine for the Ebola virus and the disease is continuing its spread in Western Africa. This virus is very dangerous because it makes its victims sick very quickly and it has a 50-70 % fatality rate.
Currently, the best prevention against the spread of Ebola is the application of basic disease interventions, which are summarized, in the following infographic, created by the Centers for Disease Control and Prevention of the United States.
The first step is to diagnose patients who are sick with Ebola. Those would express symptoms of fever, fatigue, muscle pain, headache, vomiting, diarrhoea, and bleeding. The only way to make an accurate diagnosis is by taking blood samples and sending to a good laboratory.
When a patient is diagnosed with Ebola, he or she must be isolated and all the aid helpers must wear protective gear. That patient is asked who are the people that were contacted while there were symptoms. Those contacts must be monitored for 21 days (incubation period of Ebola). If any one them showed the same symptoms, they should be tested, and then isolated in a similar way if the diagnosis is positive.
Also to help stopping the spread of Ebola, health care workers must wear protective gear and keep a clean environment. If a patient dies, safe and disinfected burial practices should be conducted. Also, it is not recommended to eat raw animal meat because many mammals (primates, bats, etc.) can transmit the virus to humans.
This is a classic, where Mr. Bean goes to a dental appointment and everything seems to go wrong! But don’t worry as when you see your dentist, these things won’t happen :)
You might have thought that it was bones, but it is actually tooth enamel that is the most solid substance of the body. It is so because of its high content (96 %) in minerals. The remaining 4 % is water and proteins. The primary mineral of enamel is called hydroxyapatite.
The second hardest substance in the body is not bone, but dentin, which is a tooth’s layer that is found under the enamel. Dentin also contains mineral hydroxyapatite (70%), and the rest is organic material (20%) and water (10%). Because dentin is softer, it is more easily decayed than enamel. Usually a cavity starts as a small hole in the enamel, but spreads more quickly and widely once bacteria reach the dentin.
Because enamel covers all teeth in the mouth, it is made to be very hard so it can chew and break soft and hard foods. But even though it’s the hardest substance of the body, enamel is brittle which means it can break more easily when under high pressure. Dentin is less brittle than enamel, and that property gives a tooth more flexibility.
The only way that the Ebola virus could be transmitted by coughing or sneezing is by the mucus. A person with Ebola and that coughs or sneezes can infect another person if his/her mucus comes into contact with the eyes, the nose, the mouth, or a wounded skin of another person.
But Ebola is not spread through the air like other viruses such as measles, chickenpox or flu. The Ebola virus can be transmitted only by direct contact between body fluids (blood, saliva, mucus, sweat, tears, vomit, feces, breast milk, urine and semen) of an infected person who has symptoms. Coughing and sneezing are not common symptoms of Ebola.
The Centers for Disease Control and Prevention (CDC) in the US has put out this info sheet to inform the population about how you can and cannot be infected with the Ebola virus.
You cannot get Ebola:
- through the air
- through water
- through food
You can only get Ebola:
- by touching the blood or body fluids of a person who is sick with or has died from Ebola;
- by touching contaminated objects, like needles;
- by touching infected animals, their blood or other body fluids, or their meat.
