What is Tooth Decay?Tooth decay refers to the damage of tooth enamel, the hard, outer layer of your teeth. It occurs when mouth bacteria produce acids that attack the enamel, leading to cavities — permanently damaged areas that develop into small openings or holes.

Causes of Tooth Decay

  1. Poor Oral Hygiene: Neglecting regular brushing and flossing can lead to plaque buildup, resulting in decay.
  2. Diet High in Sugar and Starches: Frequent consumption of sugary and starchy foods and beverages contributes to plaque acid production, eroding tooth enamel.
  3. Frequent Snacking: Constant eating increases acid exposure to teeth.
  4. Low Fluoride Exposure: Fluoride, a natural mineral, is crucial in making teeth more resistant to acid attacks and is essential in preventing decay.

Prevention Tips from iSmile Dental

  1. Maintain Good Oral Hygiene: Brush at least twice a day with fluoride toothpaste and floss daily.
  2. Eat Balanced Diets: Reduce intake of sugary and starchy snacks and beverages.
  3. Regular Dental Visits: Schedule routine checkups and cleanings at iSmile Dental.
  4. Consider Dental Sealants: A protective barrier for the chewing surfaces of back teeth, available at iSmile Dental.

Treatment Options for Tooth Decay

  1. Fillings: The standard treatment for cavities involves removing decay and filling the tooth with a suitable material.
  2. Crowns: For extensive decay, a crown or cap may be necessary.
  3. Root Canals: If decay reaches the inner pulp, a root canal may be required.
  4. Tooth Extractions: In severe cases, the decayed tooth might need to be removed.
