Restorative dentistry using dentures and implants focuses on repairing damaged or lost teeth due to various causes, for example:
 

• Chewing or biting into hard items, e.g. ice, candy, and nuts
• Dental trauma due to a fall, playing sports, or a car accident
• Bruxism or teeth-grinding
• Weak teeth from tooth decay or eating acidic foods, e.g. coffee, fruit juice, and spicy foods
• Having large fillings, as this causes the tooth structure to weaken
• Aging; those over 50 years of age are more likely to develop cracked or chipped teeth due to worn teeth
• Acid reflux disease; the stomach acid entering the mouth causing the dental enamel to erode
• Excessive alcohol consumption or an eating disorder; the stomach acid contained in vomit erodes the dental enamel
• Consumption of sugary foods or drinks, as this results in the oral bacteria breaking the sugars down into acid plaque that erodes tooth enamel
