Why Are Some People More Susceptible to Cavities?
Posted on February 27th, 2025
Many of us hear that only children get cavities. As an adult, you may then be wondering, “Why do I keep getting cavities?” The reason is not always clear, but the fact remains that many adults are cavity-prone despite taking proper care of their teeth. The causes can range from dry mouth to overcrowded teeth.
If you’re prone to tooth decay, continue reading to learn about what heightens the risk of cavities and how you can protect your smile.
Reasons Why Some People Are More Prone to Cavities
- Tooth Enamel Density
Some people naturally have weaker or thinner enamel, making their teeth more susceptible to decay.
- Hydration
Saliva helps wash away bacteria and neutralize acids in the mouth. Dry mouth, often caused by dehydration, increases cavity risk.
- Dental Alignment & Tooth Shape
Deep grooves in teeth and misaligned teeth trap food and bacteria. Overcrowded and crooked teeth are harder to clean, increasing the risk that plaque will build up and cause decay.
- Medication
Certain medications, including some antihistamines, antidepressants, and blood pressure drugs, increase the risk of dry mouth and therefore, cavities.
- Oral Bacteria
Higher levels of cavity-causing bacteria in the mouth lead to faster enamel breakdown.
Inconsistent brushing and flossing allows plaque buildup and can increase your risk of gum disease and developing cavities.
- Diet/Nutrition
Sugary and acidic foods and drinks fuel bacteria that weaken enamel. Eating a balanced diet rich in vitamins and minerals helps to strengthen teeth and gum tissue.
- Frequency of Dental Visits
Skipping regular dental exams and teeth cleanings allows cavities to develop unnoticed. Professional cleanings remove plaque and tartar, reducing the risk of decay.
- Gum Health
Gum recession, often caused by gum disease or harsh brushing habits, can leave the lowest parts of your teeth exposed and susceptible to decay.
Steps To Prevent Cavities for Cavity-Prone Teeth
The question of why some people get more cavities than others is not always easy to answer. If you’re brushing twice a day, flossing, using mouthwash, and visiting your dentist for check-ups and you still get cavities, you might benefit from trying these tips:
- Talk To Your Doctor – If you are on a specific type of medication, it may leave you more susceptible to cavities. Find out if this is a side effect of any medications you’re taking.
- Drink More Water – Dry mouth is a common culprit of tooth decay since saliva helps wash away cavity-causing bacteria. Be sure to drink plenty of water throughout the day to help reduce the likelihood of cavity development.
- Watch Your Diet – Even those of us who eat a healthy diet may not realize just how many foods we consume daily that harm tooth enamel. For example, coffee and seltzer water are not necessarily unhealthy, but they can damage teeth due to their high acidity levels. It’s also important to make sure you get the right vitamins and minerals in your diet to promote good oral health.
- Consider Your Dental Anatomy – Overcrowded or crooked teeth can be cavity-prone. This is because food gets caught between them and is left to corrode enamel. Flossing can help prevent this, but sometimes orthodontic treatment is necessary.
- Look Into Dental Sealants – Sealing teeth to prevent cavities is a treatment usually reserved for children. However, dental sealants for adults are a great option for cavity prevention. Sealants are applied to tooth surfaces to prevent bacteria from getting stuck in grooves.
