Dental Decay (Tooth Decay)

Definition, Causes, Prevention & Treatment

What Is Dental Decay?

Dental decay, also known as tooth decay or dental caries, is the gradual destruction of your tooth’s hard outer layer (enamel) caused by acids produced by bacteria in your mouth. If left untreated, decay can lead to cavities, tooth pain, infections, and even tooth loss.

Causes of Dental Decay

• Bacterial plaque buildup: Harmful bacteria in plaque produce acids that erode enamel.
• Poor oral hygiene: Infrequent brushing and flossing allow plaque to build up.
• Sugary and acidic foods: Frequent consumption of sugary snacks and acidic drinks fuels bacteria.
• Dry mouth: Saliva helps protect teeth; reduced saliva increases risk.
• Tooth anatomy: Deep grooves and pits on chewing surfaces are prone to decay.
• Medical conditions: Some illnesses and medications affect saliva flow or enamel strength.

Prevention of Dental Decay

Preventing tooth decay starts with good daily habits and regular dental care:

• Brush twice daily with fluoride toothpaste.
• Floss daily to remove plaque between teeth.
• Limit sugary and acidic foods and drinks.
• Drink plenty of water to stay hydrated and promote saliva flow.
• Visit Yaas Dental Care for regular checkups and professional cleanings every six months.
• Consider dental sealants for children and adults to protect vulnerable chewing surfaces.
• Use fluoride treatments as recommended by your dentist to strengthen enamel.

Treatment Options for Dental Decay

• Early decay (white spot lesions): May be reversed with fluoride and improved oral hygiene.
• Small cavities: Treated with tooth-coloured fillings (composite restorations).
• Larger decay or weakened tooth structure: May require inlays, onlays, or crowns to restore strength.
• Severe decay or infection: Root canal therapy or extraction may be necessary.

Risks and Complications of Untreated Dental Decay

Ignoring dental decay can lead to serious consequences, including:

• Tooth pain and sensitivity
• Infection or abscess formation
• Spread of infection to surrounding tissues or jawbone
• Tooth loss affecting chewing, speech, and appearance
• Increased risk of systemic health issues such as heart disease
