Cavities, also known as dental caries, are holes in the teeth caused by decay. The decay is a result of bacteria that produce acid, which dissolves the tooth enamel over time. Cavities can cause pain, sensitivity, and even tooth loss if left untreated. The good news is that cavities are preventable, and you can avoid them by taking care of your teeth properly.

Top 5 Things to Avoid Cavities

  • Sugary and Acidic Foods and Drinks

Eating sugary and acidic foods and drinks is one of the main causes of cavities. When you consume these types of foods and drinks, the bacteria in your mouth feed on the sugar and produce acid. This acid then attacks the tooth enamel, causing decay. To avoid cavities, limit your consumption of sugary and acidic foods and drinks such as candy, soda, sports drinks, and fruit juices. If you do consume these types of foods and drinks, brush your teeth afterward or rinse your mouth with water to remove the sugar and acid.

  • Poor Oral Hygiene

Poor oral hygiene is another major cause of cavities. If you don't brush and floss your teeth regularly, plaque builds up on your teeth, which contains bacteria that produce acid. Over time, the acid attacks the tooth enamel, causing decay. To avoid cavities, brush your teeth twice a day and floss at least once a day. Use a fluoride toothpaste and a soft-bristled toothbrush. Brush for at least two minutes, and make sure to clean all surfaces of your teeth.

  • Skipping Dental Check-Ups

Skipping dental check-ups is a common mistake that many people make. Regular dental check-ups are essential for maintaining good oral health and preventing cavities. During a dental check-up, your dentist will examine your teeth and gums for signs of cavities and other dental problems. They will also clean your teeth and remove any plaque or tartar buildup. Make sure to visit your dentist every six months for a check-up and cleaning.

  • Not Using Fluoride Toothpaste

Fluoride is a mineral that helps prevent cavities by strengthening tooth enamel. Using a fluoride toothpaste is an effective way to protect your teeth from decay. When you brush your teeth with fluoride toothpaste, the fluoride is absorbed into the enamel, making it more resistant to acid attacks. Make sure to use a fluoride toothpaste when you brush your teeth, and look for toothpaste that has the American Dental Association (ADA) seal of approval.

  • Dry Mouth

Dry mouth is a condition where your mouth produces less saliva than normal. Saliva helps to wash away food particles and neutralize acid in your mouth, so when you have dry mouth, you are more prone to cavities. Dry mouth can be caused by medications, certain medical conditions, and dehydration. To prevent dry mouth, drink plenty of water throughout the day, avoid alcohol and tobacco, and talk to your doctor if you are taking medications that cause dry mouth.


  • What are some signs of a cavity?

Some common signs of a cavity include toothache, sensitivity to hot or cold foods and drinks, visible pits or holes in the teeth, and bad breath.

  • Can I reverse a cavity?

In the early stages of a cavity, it may be possible to reverse it with good oral hygiene habits and fluoride treatments. However, once a cavity has progressed to a certain point, it cannot be reversed and will require treatment from a dentist.

  • How often should I brush my teeth?

You should brush your teeth at least twice a day, once in the morning and once before bed. If possible, it's also a good idea to brush your teeth after meals or snacks.

  • Can cavities be contagious?

Cavities themselves are not contagious, but the bacteria that cause cavities can be spread from person to person through saliva. This is why it's important to avoid sharing food, drinks, or utensils with others.

  • Are natural sweeteners like honey or agave syrup better for your teeth than sugar?

While natural sweeteners like honey and agave syrup may be healthier than refined sugar, they can still contribute to tooth decay if consumed in excess. It's important to limit your intake of all types of sweeteners to protect your teeth.

  • How often should I visit the dentist?

Regular dental check-ups are important for maintaining good oral health and preventing cavities. How often you should visit the dentist depends on your individual dental health needs.

For most people, dentists recommend visiting the dentist every six months for a routine check-up and cleaning. During these appointments, your dentist will examine your teeth and gums for signs of cavities, gum disease, and other dental problems. They may also take x-rays to check for any underlying issues.

In addition to a check-up, you'll also receive a thorough cleaning to remove any built-up plaque and tartar. Even with regular brushing and flossing, it's easy for bacteria and food particles to build up in hard-to-reach areas of your mouth. A professional cleaning can help remove these deposits and prevent cavities and gum disease.

However, some people may need to visit the dentist more frequently. If you have a history of cavities or other dental problems, your dentist may recommend more frequent check-ups to catch any issues early on. Similarly, if you have braces or other orthodontic appliances, you may need to visit the dentist more often to ensure they are properly maintained.


Cavities are a common dental problem, but they are preventable with the right dental care habits. By avoiding sugary and acidic foods and drinks, practicing good oral hygiene, visiting the dentist regularly, using fluoride toothpaste, and preventing dry mouth, you can keep your teeth healthy and strong. Remember to brush and floss regularly, and if you experience any signs of a cavity, visit your dentist for prompt treatment.
