Why Oral Hygiene Matters

Good oral hygiene is the foundation of dental health. It prevents tooth decay, gum disease, bad breath, and contributes to your overall health. Studies show that oral health is linked to heart disease, diabetes, and pregnancy complications. By following proper oral hygiene practices, you can:

Prevent Disease

  • • Reduce cavities by 40%
  • • Prevent gum disease
  • • Lower infection risk
  • • Protect tooth enamel

Save Money

  • • Avoid costly treatments
  • • Reduce emergency visits
  • • Keep natural teeth longer
  • • Lower insurance costs

Proper Brushing Technique

Brushing correctly is more important than how often you brush. Follow these evidence-based steps for optimal cleaning:

Step-by-Step Brushing Instructions

1

Choose the Right Brush

Use a soft-bristled toothbrush with a small head. Hard bristles can damage gums and enamel. Replace your brush every 3-4 months or when bristles fray.

2

Apply Fluoride Toothpaste

Use a pea-sized amount of fluoride toothpaste. For children under 3, use a rice grain-sized amount. Fluoride strengthens enamel and prevents decay.

3

Angle at 45 Degrees

Hold the brush at a 45-degree angle to your gums. This position allows bristles to clean both teeth and the gumline where plaque accumulates.

4

Use Gentle Circular Motions

Move the brush in small circular motions. Never scrub back and forth aggressively—this damages gums and wears enamel. Let the bristles do the work.

5

Clean All Surfaces

Brush the outer, inner, and chewing surfaces of each tooth:

  • • Outer surfaces (facing lips/cheeks)
  • • Inner surfaces (facing tongue/palate)
  • • Chewing surfaces (flat tops)
  • • Behind front teeth (use brush tip vertically)
6

Brush for 2 Minutes

Divide your mouth into four quadrants and spend 30 seconds on each. Use a timer or play a 2-minute song to ensure adequate brushing time.

7

Brush Your Tongue

Gently brush your tongue from back to front to remove bacteria that cause bad breath. You can also use a tongue scraper.

8

Rinse and Store Properly

Rinse your mouth and brush thoroughly. Store your toothbrush upright in an open container to air-dry. Don't cover it—bacteria thrive in moist environments.

When to Brush

Minimum: Brush twice daily—morning and night

Ideal: Brush after each meal and snack

Important: Wait 30 minutes after eating acidic foods (citrus, soda) before brushing to avoid enamel damage

Flossing: The Essential Step

Flossing removes plaque and food from between teeth and under the gumline—areas your toothbrush can't reach. These spaces account for 40% of tooth surfaces.

Why Flossing Can't Be Skipped

Not flossing is like washing only 60% of your body. You may brush perfectly, but without flossing, plaque remains between teeth, leading to cavities, gum disease, and bad breath.

How to Floss Correctly

1. Use Enough Floss

Break off 18 inches of floss. Wind most around your middle fingers, leaving 1-2 inches to work with.

2. Hold Floss Taut

Hold floss tightly between thumbs and forefingers, keeping about 1 inch of floss between hands.

3. Guide Between Teeth

Gently guide floss between teeth using a rubbing motion. Never snap floss into gums—this causes damage.

4. C-Shape Technique

Curve floss into a C-shape around each tooth. Slide it gently under the gumline. Clean up and down the side of each tooth.

5. Use Fresh Sections

Move to a clean section of floss for each tooth. Don't reuse the same section—you'll just transfer bacteria.

6. Don't Forget Back Teeth

Floss behind your last molars. Cavities commonly form here because these areas are often missed.

Flossing Alternatives

If traditional floss is difficult, these alternatives work well:

  • Floss picks: Convenient single-use plastic holders with floss
  • Water flossers: Use pressurized water to clean between teeth (good for braces)
  • Interdental brushes: Small brushes that fit between teeth
  • Floss threaders: Help thread floss under bridges and braces

Choosing the Right Products

Toothbrushes

Manual Brushes

Choose soft bristles, compact head. Replace every 3-4 months. Cost: $2-5

Electric Brushes

Oscillating or sonic models. More effective at removing plaque. Cost: $20-200

✓ Look for ADA Seal of Acceptance

Toothpaste

Must Have: Fluoride

Fluoride prevents cavities. Use 1000-1500 ppm fluoride concentration.

Special Formulas

Sensitivity, whitening, tartar control—choose based on your needs

✓ ADA approved brands are best

Age-Specific Guidelines

Infants (0-1 year)

  • • Wipe gums with clean, damp cloth after feedings
  • • Once teeth appear, brush twice daily with rice grain-sized fluoride toothpaste
  • • Use infant toothbrush with soft bristles
  • • Never put baby to bed with a bottle

Children (2-12 years)

  • • Age 2-3: Use pea-sized amount of fluoride toothpaste
  • • Age 3+: Teach proper brushing and flossing (supervise until age 7-8)
  • • Make it fun: use timers, songs, reward charts
  • • Limit sugary snacks and drinks
  • • Consider dental sealants for molars

Teens & Adults (13-64 years)

  • • Brush twice daily, floss once daily minimum
  • • Replace toothbrush every 3-4 months
  • • Limit acidic and sugary foods/drinks
  • • Don't smoke or use tobacco
  • • Visit dentist every 6 months
  • • Wear mouthguard for sports

Seniors (65+ years)

  • • Address dry mouth (common with medications)
  • • Use fluoride mouthrinse for extra cavity protection
  • • Clean dentures daily if applicable
  • • Electric toothbrush may be easier with arthritis
  • • More frequent dental visits may be needed
  • • Report any changes in taste or mouth sores

Common Mistakes to Avoid

Brushing Too Hard

Aggressive brushing damages gums and wears enamel. Use gentle pressure and let bristles do the work.

Rushing

Most people brush for only 45 seconds. You need a full 2 minutes to clean all tooth surfaces properly.

Using Old Toothbrush

Frayed bristles don't clean effectively and harbor bacteria. Replace every 3-4 months or after illness.

Skipping Flossing

Brushing alone misses 40% of tooth surfaces. Floss daily to prevent cavities and gum disease between teeth.

Wrong Technique

Back-and-forth scrubbing is ineffective. Use gentle circular motions at a 45-degree angle to gums.

Rinsing After Brushing

Rinsing washes away protective fluoride. Just spit out excess toothpaste and leave fluoride on teeth.
