Dear Dr. House,
My dentist found another cavity today! I have had at least one cavity, sometimes more, at every visit for the last few years .
I brush and floss just like I have always done. I haven’t had cavities in a decade and now this!
Am I paying for his son to go to college or what?

Dear Tooth Decayed,
I hear your frustration. It’s time to dig in and find out what is really going on with your mouth.
Here are some of my thoughts :
1. The mouth is a really a window into the body. We often see health issues show up in the mouth before they show up in the body. New cavities can be a sign of a metabolic disease like diabetes. They can also be a sign of chronic acid reflux ( also called heart burn) which is a serious condition if it happens often. We also notice an increase in cavities when someone has a sleep disorder or chronic allergies.
Go see your primary care physician and have some blood work done to rule out any serious underlying conditions .
2. A dry mouth can lead to an increase in cavities . There are many medications that have a side effect of drying out the mouth. It is worth checking on the side effects of any medications you are taking .
You can’t stop taking medication, but you can drink more water or use over the counter aids like biotene to help moisturize your mouth.
3. Acidic drinks can cause an increase in cavities. Juices, sodas, and sports drinks are shockingly acidic. Alcohol and kombucha are also acidic. Coffee and tea are less acidic, but the sweeteners that we add to them also cause cavities .
Water is really the best choice of drink!
4. Finally, you may have to add something to your normal brushing and flossing routine. The mouth ages just like every other part of our bodies and we have to continue to update our habits to keep ourselves young. I have noticed that I can’t eat as much anymore without gaining weight and I have to lotion my hands and feet, when I never did that before!
I hope this answer gives you somewhere to start!
