Many people see cavities as something that only affects children, as though you’ll someday grow out of having them. However, cavities are one of the most common dental issues, affecting people of all ages. Whether you’re a parent concerned about your child’s oral health or simply wondering how your dental habits stack up, understanding cavities is key to better oral health and preventing gingivitis

9 out of 10 adults will have at least 1 cavity during their lifetime. While anyone can develop cavities, the truth is, it’s always better to have zero cavities, no matter your age. With proper dental hygiene and regular exams, you can avoid cavities and protect your smile.

How Cavities Form 

Cavities, also known as dental caries, are very small holes that can form on your enamel due to tooth decay. This starts when bacteria in your mouth feast on sugars from the foods and drinks you consume. When bacteria metabolize these sugars, they produce acids that gradually wear away the enamel, the protective layer of your teeth. 

The more frequently you consume sugary or acidic foods and beverages, the more fuel you provide for these bacteria. Over time, plaque builds up on your teeth, creating a breeding ground for bacterial activity, which can lead to small holes in your teeth. These are cavities. If left untreated, they can worsen and affect deeper layers of the tooth, causing pain or even infection. 

How Many Cavities Are Normal? 

The idea of a “normal” number of cavities varies across age groups, though we should always aim for none. Across a lifetime, 9 out of 10 adults will have at least 1 cavity. However, research provides insight into how common cavities are for different populations. 

  • Children: 57% of children aged 6 to 11 have or have had a cavity.
  • Teens: 59% of adolescents aged 12 to 19 have experienced cavities in their permanent teeth.
  • Adults: 96% of adults over the age of 20 have had cavities in their permanent teeth at some point.

On average, children from 6 to 19 have 2.5 cavities. While these statistics highlight the prevalence of cavities, it’s important to note that any cavity, regardless of age, is less than ideal. Maintaining excellent oral health habits is the best way to reduce your risk and strive for a cavity-free smile.

What Increases the Risk of Cavities?

Several factors can contribute to an increased risk of developing cavities, including:

  • Poor oral hygiene: Irregular or improper brushing and flossing can allow plaque and bacteria to build up, leading to tooth decay over time.
  • Diet high in sugar and acidic foods: Frequently consuming sugary or acidic foods and drinks, such as candy, soda, or fruit juices, can erode enamel and create an environment where bacteria thrive.
  • Dry mouth: Saliva plays a key role in washing away food particles and neutralizing acids.
  • Receding gums: Exposed tooth roots from receding gums are more vulnerable to decay as they lack the protective enamel found on the crowns of teeth.
  • Tooth misalignment: Crowded or crooked teeth can create hard-to-reach spaces, making it easier for plaque to accumulate.
  • Frequent snacking or sipping: Constantly eating or sipping beverages throughout the day provides regular fuel for cavity-causing bacteria.
  • Age-related changes: Over time, natural wear and tear and other age-related changes, can make teeth more susceptible to decay.

Some of these factors you can’t change, such as if your genetics make you more prone to dry mouth. But, many times, cavities are entirely preventable with some lifestyle adjustments.

Best Practices for Oral Health 

Taking care of your teeth doesn’t have to be complicated. Follow these oral health best practices to keep cavities at bay:

  • Brush effectively: Use a fluoride toothpaste to brush your teeth twice a day for at least 2 minutes. Make sure to use gentle, circular motions and pay attention to all surfaces of your teeth, including the gumline.
  • Floss daily: Flossing removes food particles and plaque from between teeth, where your toothbrush can’t reach. Incorporate flossing into your nightly routine to prevent buildup in these hard-to-reach areas.
  • Use mouthwash: An antimicrobial rinse can help reduce bacteria in your mouth, while a fluoride rinse strengthens your enamel. Speak with your dentist about which product best suits your needs.
  • Schedule regular checkups: Professional cleanings and exams are essential for spotting cavities early and addressing any concerns before they worsen. Aim for a visit every 6 months.

Lifestyle Tips to Avoid Cavities 

Beyond your daily oral care routine, there are additional steps you can take to prevent cavities:

  • Make healthier dietary choices: Limit your intake of sugary snacks, candies, and beverages like soda and juice. Opt for tooth-friendly alternatives, such as fresh fruits, vegetables, and dairy products.
  • Stay hydrated: Drinking water throughout the day helps wash away food particles and bacteria while encouraging saliva production. Saliva plays a crucial role in neutralizing acids and restoring minerals to your enamel.
  • Consider preventive treatments: Dental sealants and fluoride treatments are great preventive measures. Sealants protect the chewing surfaces of your teeth from decay, while fluoride strengthens enamel and reduces the risk of cavity formation.
  • Chew sugar-free gum: Sugar-free gum, especially those containing xylitol, can stimulate saliva production and naturally help clean your teeth between meals.
