Tooth Decay: Symptoms, Causes, and Treatment

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.
