GSG Smackdown, lecture on dental health and nutrition, part 3 of 3

Dr. Jorgenson’s lecture had some interesting facts, including the table below, showing how acidic soft drinks are. The table shows how much of your tooth is lost in 14 days of exposure to Coke, Pepsi, Mt. Dew, and others. (And here’s me pointing out: if it dissolves hard enamel, what is it doing to vulnerable soft tissues and organs?)

Dr. J stated that whitening and tartar-control toothpastes are terribly hard on your teeth. She personally doesn’t use toothpaste, because the chemically-achieved slippery “feeling” of clean, and the minty taste, give you a false sense of security about your teeth actually being clean. She brushes with nothing! She said that plaque on your teeth –that stuff you can scrape off with your fingernail–is just millions of bacteria organisms. She recommends gently putting baking soda on your teeth and swishing it in your mouth for as long as you can before rinsing, for alkalinity. (Don’t brush with it, though, as it is abrasive on your teeth.)

She said to brush your child’s teeth from behind, putting your hand under the chin and pulling their head back–much like the dentist does, because you can see in the mouth and reach all the surfaces that way.

She said that she doesn’t tell people not to eat sugar because everyone does it. However, she begs us to eat it only once in a 24-hour period, and ALL IN ONE SITTING, that the worst thing you can do is eat it throughout the day. (I agree: then your body constantly has the strain of having to neutralize those acids and pump insulin, etc.)

You can keep bacteria on your teeth at bay with just one tooth brushing and flossing a day, but make sure you’re very thorough.

Which beverages dissolve teeth?

BeveragepH value% of tooth lost in 14 days
Diet Coca-Cola3.221.5
Diet Pepsi-Cola2.941.5
Dr. Pepper2.91.7
Diet Dr. Pepper2.991.5
Mountain Dew3.146.1
Diet Mountain Dew3.278
Diet Sprite3.343.7
Canada Dry Ginger ale2.943.5
A&W Rootbeer4.8-.1
Arizona Iced Tea2.944.9
Brewed Black Tea5.36.22
Brewed black coffee6.25.19
Tap Water6.7-.02

Remember – a neutral pH is 7.0.   So, the lower the pH the more acidic the drink is.

  1. I am not understanding the Beverage chart. Among other things, how can Diet Mountain Dew have a pH value of 3.27 with 8% of tooth lost, then Sprite has the same pH value of 3.27 with only 4% tooth lost?

    1. I don’t know–I assume these are just reports of a real experiment. Of course pH level is just one thing that affects how much of the tooth is lost. But it’s a good question…..I’ll ask Dr. J if she knows!

  2. Bravo! I scoff every time I see the ridiculous commercial for the “enamel preserving” toothpaste because they leave out the most acidic food on the planet-soda!
