A cavity, also known as tooth decay, is damage to the hard surface of your teeth that develops into tiny openings or holes. It’s one of the most common dental problems worldwide.
🦷 What Causes Cavities
Cavities are caused by acid-producing bacteria in your mouth. These bacteria feed on sugars from food and drinks, producing acid that erodes the tooth enamel over time.
Key factors include:
- Poor oral hygiene – not brushing or flossing regularly
- Frequent sugary or acidic foods – soda, candy, juice
- Dry mouth – less saliva means less natural protection
- Plaque buildup – sticky film on teeth that harbors bacteria
⚠️ Signs of a Cavity
- Toothache or spontaneous pain
- Sensitivity to hot, cold, or sweet foods
- Visible holes or pits in teeth
- Brown, black, or white staining on the tooth surface
🩺 How Cavities Are Treated
- Fluoride treatments – can help reverse very early decay
- Fillings – removing decay and filling with composite, amalgam, or other material
- Crowns – for extensive decay
- Root canal – if decay reaches the tooth pulp
🟢 Preventing Cavities
- Brush teeth twice a day with fluoride toothpaste
- Floss daily
- Limit sugary and acidic foods
- Drink plenty of water, especially after meals
- Regular dental checkups (every 6 months)
💡 Fun fact: Cavities don’t happen overnight—they develop slowly over months or years, so early care can save your tooth.
