Cavities Explained: What They Are and How You Can Stop Them
A toothache or dark spot isn’t always the first sign of trouble. Cavities often begin quietly. Knowing how they form and how to guard against them helps you protect your smile.
WHAT ARE CAVITIES?
Cavities (also called dental caries or tooth decay) are damaged areas on the hard surfaces of your teeth.
They start when acid and bacteria wear down the tooth’s enamel. Over time, the decay may reach deeper layers like dentin and even the tooth’s nerve if untreated.
The process begins with plaque—a sticky film of bacteria that feeds on sugars and starches in your mouth. Each time you eat or drink, those bacteria produce acids that attack enamel.
HOW DO CAVITIES DEVELOP?
Plaque forms on your teeth because bacteria stick to leftover sugars and food particles.
Acid attacks the enamel, causing minerals like calcium and phosphate to come away (demineralization).
Remineralization tries to repair the early weak spots using minerals from saliva and fluoride.
If acid attacks happen too often and rinse cycles aren’t enough, the enamel weakens further and breaks down.
- That breakdown leads to a hole or cavity. At that point, the damage is permanent and needs dental work to fix.
High sugar and starch intake: Every time you eat sweets or starchy snacks, you feed cavity-causing bacteria.
Frequent snacking or sipping: Constant exposure to sugars gives bacteria nonstop fuel.
Poor oral hygiene: Failing to brush and floss daily lets plaque build and acid persist.
Low fluoride exposure: Fluoride helps strengthen enamel and makes it harder for acid to remove minerals.
Dry mouth or low saliva: Saliva helps neutralize acids and remineralize enamel. Conditions or medications that reduce saliva raise cavity risk.
- Deep grooves or pits on teeth: These are hard to clean and often the first places decay starts. Sealants may help protect them.
Brush your teeth two times a day with fluoride toothpaste. Focus on covering every surface for about two minutes.
Floss daily to clean between teeth, where toothbrushes can’t reach.
Use mouthwash or rinses that contain fluoride to give your enamel extra protection.
Limit sugary and acidic foods and drinks. Try to reserve them for mealtimes, not constant snacking.
Drink water, especially if it’s fluoridated. It helps rinse out sugars and acids.
Consider dental sealants, especially on your molars. These are protective coatings your dentist can apply to grooves in teeth to block decay.
Visit your dentist regularly for cleanings and exams. They can spot early decay before a full-blown cavity forms.
- If you have risk conditions like dry mouth or take medications that reduce saliva flow, mention them to your dentist so they can adjust your care.
