How Do I Prevent Cavities?

One of the best ways to prevent a cavity from happening is to practice good oral hygiene. This includes brushing your teeth twice a day, flossing regularly, and visiting your dentist every six months for regular cleanings. Another way to prevent cavities is to avoid sugary foods and beverages such as soda and candies. Also, remember to stay hydrated because a dry mouth can also increase the risk of cavities developing.

How Do I Know if I Have A Cavity?


One of the main signs that you have a cavity is sensitivity to different temperatures. With cavities, the enamel on a tooth wears down which exposes the nerves inside of your teeth. When these nerves are exposed and no longer protected by the tooth’s enamel, then hot and cold foods can stimulate those nerves. This feeling can linger a while after the exposure to the temperature and can be quite uncomfortable.

Another sensitivity you may experience if you have a cavity is sweet and sugary foods and beverages. Similar to the temperature sensitivity, the discomfort after exposure to sweets can linger.


Toothaches can be very uncomfortable and are something you should not ignore. Toothaches can signify many different oral health issues, but one of the most common is a cavity. This aching pain can come on suddenly or gradually and should be addressed quickly, so the pain doesn’t worsen. Oftentimes, the pain from a toothache is most prominent when you are eating or clenching your jaw.


One of the first signs you may see when a cavity is developing is staining on your tooth. At first, the stain may appear white, and then as the cavity worsens and advances, the stain will become darker, often brown or black. 

Hole in Tooth

If a cavity has been present for a long time, the tooth will develop a hole due to tooth decay. Oftentimes, you will be able to see this hole in a mirror or be able to feel it with your tongue. However, in some cases, you may never be able to see or feel the hole, which is why it is important to regularly visit a dentist. 

What Do I Do If I Have a Cavity?

If you experience or see any of the symptoms listed above, it is very important for you to schedule a visit to a dentist. If a cavity goes on too long without being treated properly, it can lead to more significant and severe health issues, not to mention discomfort. Schedule an appointment with Dr. Emma Wu to have your cavity filled.
