Select each layer to understand its role in your oral health.

The hard outer layer that protects your tooth from daily wear and acid.

Enamel: The hard outer layer that protects your tooth from daily wear and acid.

Dentin: Softer layer beneath enamel containing tiny tubes connected to nerves.

Pulp: Inner core with nerves and blood vessels — sensitive to deep decay.

Gums: Soft tissue surrounding teeth. Healthy gums are pink and firm.

Plaque: Sticky bacterial film that forms on teeth and leads to decay.

Tooth Decay: Cavities form when acids erode enamel. Early treatment prevents pain.

Cavities form when plaque bacteria produce acids that erode enamel. Early treatment prevents pain and tooth loss.

Gingivitis and periodontitis affect the tissues supporting your teeth. Regular cleanings and good hygiene are key.

Sharp pain from hot, cold, or sweet foods often signals worn enamel or exposed dentin. Treatment can bring relief.

Persistent halitosis may indicate gum disease, dry mouth, or poor oral hygiene. A dental checkup can identify the cause.

Sticky bacterial film on teeth leads to decay and gum problems. Brushing, flossing, and professional cleanings remove it.

Build a simple routine that protects your teeth and gums every day.

Brush twice daily for two minutes using fluoride toothpaste. Use gentle circular motions and don't forget your gum line.
Floss once a day to remove plaque between teeth where your brush can't reach.
Replace your toothbrush every 3–4 months or sooner if bristles are frayed.
Limit sugary snacks and drinks, especially between meals.

Know the layers of your teeth to better understand common dental problems.

Enamel is the hard outer layer that protects your tooth. It's the strongest substance in your body but can be damaged by acid.
Dentin lies beneath enamel and contains tiny tubes that connect to the nerve. When exposed, it causes sensitivity.
The pulp contains nerves and blood vessels. Deep decay or injury reaching the pulp often requires root canal treatment.
Gums surround and support your teeth. Healthy gums are pink and firm, not red, swollen, or bleeding.

Don't wait for pain — regular checkups prevent serious problems.

Schedule a checkup every 6 months even if you feel fine. Early detection saves time, money, and discomfort.
See a dentist immediately for persistent toothache, swelling, bleeding gums, or a cracked tooth.
Children should have their first dental visit by age one or when their first tooth appears.
If you notice white spots, dark stains, or sensitivity, book an appointment before the problem worsens.
