Today, June 20, marks the Summer Solstice, signaling the peak season for outdoor activities, including picnics and cookouts. All those smells and tastes may bring back fond summertime memories. But did you know that juicy tomatoes and fresh-squeezed lemonade contain acid that can be hard on your teeth?
While most any fruit or vegetable is a healthy food choice, you should be aware of the effects on your tooth health. Those foods that have high acidity could be damaging, since acid can remain on teeth and break down your tooth enamel, the protective layer on exterior of your teeth.
Acid content is measured its pH value, with 7.0 indicating neutral acidity. These pH levels are ranked on a descending scale, so a pH level of 0 indicates the highest acid level. The higher numbers (from 7.0 -14.0) are lowest pH, also classified as “alkaline”, or non-acidic.
The FDA ranks the average acidity of foods, and it turns out that many summer staples made the wrong end of the list. Several of our Meyer & Johns staff’s favorite fresh seasonal fruits are in the Top Ten most-acidic foods, according to Colgate:
- Lemon Juice – #1
- Limes – #2
- Grapes – #5
- Blueberries – #8

The good news is that there are easy remedies for reducing the residual acid on teeth.
- Drink – The simplest solution is the most important – for both physical AND oral health. Drinking plenty of water ensures that any remaining food particles, plaque-causing sugars or residual acids are flushed away. Drinking enough water is also critical for proper hydration during the sweaty summer months.
- Dairy – Besides naturally reducing acid in your mouth, milk, cheeses and other dairy products contain calcium and casein (milk protein). Both of these help strengthen teeth and protect your enamel.
- Brush – As always, we recommend brushing after meals or sugary snacks. This may not be easy at picnics, cookouts or the lake, but it’s still the most effective way to keep a healthy smile.
