If you’re one of Dr. Neuhaus’ many patients who do whitening treatments, be careful of red wine. In fact, if it’s between a coffee beverage or red wine, dental researchers in Sao Paulo, Brazil suggest you choose the coffee. In a study, the scientists looked at human molars exposed to coffee and red wine both during and after whitening treatments.
During the treatments, remineralization of the enamel with artificial saliva and then a subsequent bleaching session was effective in preventing enamel staining. But, once the whitening treatments stopped, both coffee and wine did cause enamel color changes -- and the wine did more damage than did coffee.
When it comes to cheese, go right ahead and enjoy. It seems that consuming cheese and other dairy products may actually help protect teeth against cavities.
According to a study recently published in General Dentistry, people who eat cheese show a rise in plaque pH -- and that’s a good thing. A pH level lower than 5.5 puts a person at risk for tooth erosion. Researchers believe that the rise in pH levels from eating cheese may occur due to increased saliva production, possibly caused by the action of chewing. And, various compounds in cheese may adhere to tooth enamel, further protecting teeth from acid.
