Cavities & Tooth Decay Solutions
What causes cavities, how to prevent them, and how we treat them.
1 min read
Cavities, also called tooth decay or dental caries, are a common dental problem affecting people of all ages. They form when harmful bacteria in your mouth produce acids that erode your tooth enamel. Our goal at Mega Dental is to help you understand, prevent, and treat cavities to keep your smile healthy and bright.
Why cavities happen
Every time you eat or drink, sugars and carbohydrates feed bacteria in your mouth. These bacteria produce acid that wears away your enamel — the hard, protective outer layer of your teeth. Saliva helps neutralize the acids, but if the damage outpaces repair, cavities start forming.
Common signs of cavities
Watch for tooth sensitivity to hot, cold, or sweet foods, visible holes or dark spots, a persistent toothache (especially while chewing), and bad breath or an unpleasant taste. Left untreated, cavities can progress into infections that affect the nerve in the center of the tooth.
Risk factors
A diet high in sugars and acids, dry mouth from medications or medical conditions, poor oral hygiene, and conditions like diabetes all increase your risk. Children, adults, and seniors each face cavity risks — nearly half of kids aged 6–9 have cavities, and almost all adults over 65 have had them.
Prevention and treatment
Prevention is always better than treatment: brush and floss daily, use fluoride products, choose a balanced diet, and schedule cleanings and exams every six months. When a cavity does form, we treat it with fluoride treatments for very early decay, tooth-colored fillings, root canal therapy for decay that reaches the pulp, or extraction when a tooth can't be saved — followed by a bridge or implant to restore your smile.
Frequently Asked Questions
- Are cavities preventable?
- Yes. Regular dental hygiene, a healthy diet, fluoride products, and routine checkups prevent most cavities.
- Can cavities heal on their own?
- No. Once a cavity forms, it won't heal by itself — a filling is needed to stop the decay and restore the tooth. Early fluoride can reverse very early demineralization, but a true cavity needs treatment.
- Do baby teeth matter if they'll fall out anyway?
- Yes. Decay in baby teeth can spread and affect the adult teeth beneath them, and can cause pain and infection. Treating baby teeth is essential for overall dental health.
- How often should I visit the dentist?
- Every six months for cleanings and exams to catch issues early and maintain good oral health.
