What Is a Cavity?
Cavities (dental caries) happen when acids produced by oral bacteria weaken and break down tooth enamel. The process starts small—white spots and sensitivity—and can progress into holes that require fillings if not addressed early.
Brush for Protection (2× Daily, 2 Minutes)
Use a soft-bristled manual or electric brush with fluoride toothpaste. Angle at 45° toward the gumline and use short strokes across all surfaces. Gentle pressure is key—scrubbing too hard can wear enamel and gums.
- Timer/pacer: Many electric brushes buzz every 30 seconds—follow the cues.
- Replace heads: Every 3–4 months, or sooner if bristles fray.
Floss to Reach Between Teeth (Daily)
Flossing removes plaque and food between teeth and under the gumline where brushes can’t reach. If traditional floss is difficult, try floss picks, interdental brushes, or a water flosser.
Fluoride & Remineralization
Fluoride helps rebuild weakened enamel and makes it more resistant to future acid attacks. Choose an ADA-accepted fluoride toothpaste and consider an alcohol-free fluoride rinse if your cavity risk is higher.
- Professionally applied fluoride: Ask us during your cleaning if you’re prone to decay.
- Wait to brush after acids: After soda, sports drinks, or citrus, rinse with water and wait ~30 minutes before brushing.
Sealants Protect Deep Grooves
Sealants are thin protective coatings painted on the chewing surfaces of back teeth to block food and bacteria. They are quick, comfortable, and especially effective for kids and teens—but adults with deep grooves can benefit too.
Diet, Sugar & Timing
- Limit frequency: Frequent sipping/snacking feeds bacteria all day. Aim for defined meal times.
- Choose tooth-friendly foods: Cheese, nuts, veggies, and water help neutralize acids.
- Consider xylitol: Sugar-free gum or mints with xylitol can reduce cavity-causing bacteria.
- Sticky sweets: Caramels, gummies, and dried fruit cling to teeth—enjoy rarely and rinse after.
Watch for Dry Mouth (Xerostomia)
Saliva protects teeth by neutralizing acids and delivering minerals. Medications, mouth breathing, and certain conditions can reduce saliva flow, raising cavity risk.
- Sip water often and use a humidifier at night.
- Choose alcohol-free rinses; avoid tobacco and excess caffeine.
- Ask us about saliva substitutes or prescription-strength fluoride.
Cavity Prevention for Kids & Seniors
Kids & Teens
- First dental visit by age one; regular checkups every six months.
- Fluoride toothpaste: smear (rice-sized) for toddlers; pea-sized after age 3.
- Sealants on permanent molars soon after they erupt.
Older Adults
- Ask about high-fluoride toothpaste or trays if decay risk increases.
- Manage dry mouth; review medications with your dentist/physician.
- Clean around crowns/bridges/implants with interdental tools.
Early Warning Signs—Don’t Wait
White or brown spots, sensitivity to sweets/cold, or rough areas may signal early decay. The sooner we evaluate, the more conservative your treatment can be.

Preventing Cavities: FAQs
Is an electric toothbrush better for cavity prevention?
Many patients get a more thorough clean with electric brushes due to consistent motion, built-in timers, and pressure sensors.
Which toothpaste should I use?
A fluoride toothpaste with the ADA Seal is a great start. If you have sensitivity or higher risk, ask us for a personalized recommendation.
How often should kids have dental checkups?
Generally every 6 months, but we’ll tailor the schedule to your child’s needs and cavity risk.
