Tooth decay (also known as dental caries or cavities) is one of the most common oral health problems worldwide. If left untreated, it can lead to pain, infection, and even tooth loss. The good news? Early detection and treatment can save your natural teeth and prevent costly dental work.
1. Symptoms of Tooth Decay
Tooth decay develops gradually, so recognizing the early signs is key. You may notice:
- White or brown spots on the enamel
- Tooth sensitivity to hot, cold, or sweet foods and drinks
- Mild to sharp toothache that comes and goes
- Visible holes or pits in the teeth
- Bad breath or an unpleasant taste in the mouth
- In severe cases, swelling or pus around the tooth
Greenfield’s Tip: Even if there’s no pain, any visible discoloration or sensitivity should be checked by a dentist early – prevention is always easier than treatment.

2. Causes of Tooth Decay
Tooth decay occurs when bacteria in the mouth produce acids that erode the tooth enamel. Common causes include:
- Poor oral hygiene – not brushing and flossing daily
- Frequent snacking or sugary drinks – fuels bacterial growth
- Dry mouth – reduced saliva makes it easier for plaque to form
- Worn fillings or dental work – can trap bacteria
- Medical conditions – acid reflux, eating disorders, or certain medications
3. Treatment Options at Greenfield Dental
The right treatment depends on the stage of decay:
- Fluoride treatment – for very early-stage decay, helps remineralize enamel
- Dental fillings – for small cavities, restoring function and shape
- Crowns – for larger decay or weakened teeth
- Root canal treatment – when decay reaches the tooth pulp
- Tooth extraction – in severe, untreatable cases
Greenfield’s Tip: At Greenfield Dental, we use advanced imaging to detect decay early and recommend personalized treatment plansthat protect your natural teeth as much as possible.


4. How to Prevent Tooth Decay
- Brush twice daily with fluoride toothpaste
- Floss at least once a day
- Limit sugary snacks and drinks
- Visit your dentist every 6 months for checkups
- Drink plenty of water to maintain saliva flow
