We all know it’s good to brush your teeth at least twice a day. It’s even better to brush after eating, but unfortunately most of us don’t have the time for that. Cavities form as a result of tooth decay. Tooth decay is caused by the acidity in foods. Acidity levels, also known as pH levels vary by the type of food and drink. Take a look at the pH Level chart to see if what you are eating and drinking is increasing your risk for cavities. If it’s been over six months since you have seen your hygienist, make sure to book your appointment with Dr. Cheung at Louis K. Cheung DDS in Kirkland, WA to ensure that your teeth stay healthy. Your hygienist at Louis K. Cheung DDS can also provide you with other ways to prevent tooth decay.
