Hi!

There are a couple of things you should be looking for. You may think she isn't eating sugar, but she may be getting other forms of sugar that you don't realize can be causing cavities. You should watch the overall refined carbohydrates, and fruits while they are healthy are also a source of cavity causing sugar, especially dried fruit, which is the worst because of it is also sticky.

The other concern, besides sugar, is acid. Many people, including children, have too much acid and acid will eat away the enamel of the teeth. You can buy pH paper or strips in the pharmacy and see if your child's saliva is acidic (below 7) or basic (above 7). Xylitol is an excellent sugar substitute that will neutralize the acid in the mouth and reduce the growth of cavity-causing bacteria. I personally recommend Zellies (zellies.com) gum and mints because they are all natural and non-GMO. My grandchildren have at least one mint (sucking candy) after every meal and snack.

Good luck,

Robert M. Hersh, DMD

Not in the same way that germs are spread from one person to another. However, if there is plaque and germs between two teeth, a cavity can start on one of the teeth and then that tooth can become a reservoir of germs that can attack the other tooth. So, in a way yes, a cavity can spread to the next tooth.

Mouth Ulcers Keep Coming Back

That could be a sign that you are run down, over stressed, or vitamin deficient. Listen to your body. Get 7-8 hours of sleep; eat a healthy, well-balanced diet and take a multivitamin READ MORE
That could be a sign that you are run down, over stressed, or vitamin deficient. Listen to your body. Get 7-8 hours of sleep; eat a healthy, well-balanced diet and take a multivitamin daily; try to control the stress in your life. If you are in school, that might be difficult. Apthous ulcers are very common in students, especially around exam time. Try relaxation techniques, such as yoga or transcendental meditation.

Are there any home remedies to treat canker sores?

Many people are prone to developing canker sores. It may be a sign of a vitamin deficiency, particularly folic acid or zinc (and sometimes calcium). I recommend you rinse your mouth with either warm salt water or baking soda rinse (dissolve 1 teaspoon of baking soda in 1/2 cup warm water). You can also dab a small amount of milk of magnesia on your canker sore a few times a day. Avoid abrasive, acidic, or spicy foods that can cause further irritation and pain. There are many other home remedies which you can find on the internet as well.

Happy to help,

Bloody painful gums, what should I do?

Without examining you and without knowing your medical history, I have to qualify my answer. Assuming you have no medical conditions that could be the cause, then your bleeding gums is most likely an immune response to bacterial plaque on your teeth and under your gums.
You should begin by rinsing several times a day with warm salt water, which will help reduce the inflammation. Next, you need to remove the plaque from your teeth. In my office, we strongly recommend an electric toothbrush along with a water irrigating device (on a gentle setting). At first, you will notice an increase in the bleeding, but as they begin to heal, that should diminish.
Next, I would recommend a visit to a dentist who can do a more thorough evaluation and help you treat your condition.
