Wine After Whitening Nullifies Impact

Wine After Whitening Nullifies Impact

Drinking wine after having your teeth whitened may be the worst substance one can consume. Even worse than coffee.
A recent study in the February issue of Acta Odontologica Scandinavicashowed this was the case based on a Brazil research team’s findings. The study showed that the stains produced from wine were more damaging than the coffee stains.
The group of researchers from a practice in Sao Paolo, Brazil explored the staining that resulted from red wine and coffee before and after a teeth-whitening treatment. The molars were broken into 11 groups utilizing wine, coffee and a control substance. A spectrophotometer was used to determine color change among the teeth.
The research indicated that there wasn’t much change in the concentration of the carbamide peroxide during the whitening treatment. When the treatment concluded, however, there was a large difference in the concentration involving the groups treated with coffee and red wine.
The research team explained its findings by stating that during remineralization of the enamel, the saliva and bleaching agent thwart the possible staining of the enamel. But after the treatment was finished, the red wine and coffee stained the enamel. The stains from the wine were definitively worse, based on this study.

Gum Cells Utilized to Grow Teeth

Gum Cells Utilized to Grow Teeth

Gum cells were recently used as a way of growing new teeth—something that could be a major breakthrough in dentistry.
Based on this King’s College (London) research, missing teeth could one day be grown from gum cells.
To successfully grow the teeth, the researchers took epithelial cells from the gums and combined them with mesenchyme cells from mice. The research team then managed to promote the growth of new teeth through the epithelial gum cells.
The researchers later transplanted the combination of cells into the mice, which produced the development of human/mouth teeth that had a working root system.
The information appeared in the Journal of Dental Research.
The research team warned for patience, however. It still may take years before dentists can implement this process with humans.


Researchers will have to find a way to acquire a supply of mesenchyme cells that would result in a feasible way to grow these teeth in humans on a consistent basis. If the right amount of mesenchyme cells is found, the research team can proceed with the next step toward making this practice widespread.

New Study Indicates Fluoride Lowers Tooth Decay

New Study Indicates Fluoride Lowers Tooth Decay

The debate will continue but a new study recently demonstrated the positive impact fluoride has on dental health.
The researchers from the University of North Carolina at Chapel Hill and the University of Adelaide in Australia concluded that when fluoride is placed in drinking water, there are positive results and less tooth decay. This even applies to people who weren’t exposed to fluoridated water as children.
Some previous studies came to the conclusion that only children who consumed fluoride from birth could benefit from it. But this study debunks that notion. This information shows that even more people may benefit from fluoride than most studies would even indicate.
To compile the data, the research team looked at nearly 3,800 people aged 15 and older in Australia from 2004 through 2006. The researchers examined the levels of decay of the people based on where they lived since 1964. The locations were then matched up to see if the people lived in communities with fluoridated water. A determination was then made on how much fluoride each person had been exposed to and if there was any correlation with tooth decay or other oral health problems.
The information also shows that people who spent more than 75 percent of their lifetime living in towns with fluoridated water had as many as 30 percent less instances of tooth decay when compared to their counterparts who lived with fluoridated water for less than 25 percent of their life.
The study appears in the Journal of Dental Research.
The reason for the study is because many Australian cities without fluoridation want to add fluoride to their cities, which is a no-brainer according to Kaye Roberts-Thomson, one of the study’s co-authors. Many of the people against fluoride, however, would beg to differ.
