Dental Cavities & Tooth Decay
Stop tooth decay before it starts.
2 min read
Cavities, also called tooth decay or dental caries, are among the most common dental problems we treat at Mega Dental. They form when harmful bacteria in your mouth produce acids that erode your tooth enamel. Our goal is to help you understand, prevent, and treat cavities so your smile stays healthy and bright.
- Early detection with regular exams
- Fluoride treatments to strengthen enamel
- Tooth-colored fillings that match your smile
- Personalized prevention plan for every age
Overview
Cavities form when harmful bacteria in your mouth produce acids that erode your tooth enamel, eventually causing holes in your teeth. Every time you eat or drink, sugars and carbohydrates feed these bacteria. Saliva helps neutralize the acids, but when damage outpaces repair, cavities start forming. Left untreated, decay can progress into infections that affect the nerve inside the tooth — leading to more serious health concerns.
Common signs and symptoms
Tooth sensitivity to hot, cold, or sweet foods, visible holes or dark spots on your teeth, a persistent toothache (especially while chewing), and lingering bad breath are all common signs of a cavity. If you notice any of these, schedule a visit — early treatment prevents decay from reaching the nerve.
Who is most at risk
A diet high in sugars and acids, dry mouth from medications or medical conditions, inconsistent brushing and flossing, and conditions like diabetes all increase your risk of cavities. We help you identify and manage these risk factors so you can stay ahead of decay.
Cavities at every age
Nearly half of kids aged 6–9 develop cavities, often from sugary snacks and developing brushing habits. One in five adults aged 20–64 has an untreated cavity. Almost all adults over 65 have had cavities, and receding gums can expose roots to new decay. Regular visits protect every smile at every stage of life.
Prevention tips from our team
Brush twice daily and floss every day, use fluoride toothpaste to strengthen enamel, choose a balanced diet low in sugars and acids, and schedule cleanings and exams every six months. Prevention is always easier, more comfortable, and more affordable than treatment.
Treatment options
For early decay, fluoride treatments can help restore enamel. Once a cavity forms, a tooth-colored filling restores the tooth. If decay reaches the pulp, root canal therapy can save the tooth. In severe cases where the tooth can't be saved, a gentle extraction followed by a bridge or implant restores your smile.
Frequently Asked Questions
- Are cavities preventable?
- Yes. With regular dental hygiene, a healthy diet, routine checkups, and fluoride products, most cavities can be prevented. We'll help you build a prevention plan that fits your life.
- Can cavities heal on their own?
- No. Cavities don't heal themselves — they only get worse. Treatments like fillings stop the decay and restore the tooth, which is why early treatment matters.
- What should I do if I think I have a cavity?
- Schedule an appointment as soon as you notice sensitivity or pain. Early treatment is simpler, more comfortable, and far less expensive than waiting.
- Do children need fluoride?
- Yes. Fluoride is safe and effective for children and helps reduce cavities. We'll recommend the right fluoride approach for your child's age and risk.
- Do baby teeth matter if they fall out anyway?
- Yes. Decay in baby teeth can spread and affect the adult teeth beneath them, and infected baby teeth can cause pain and affect development. Treating them matters.
- Is a cavity serious only if it hurts?
- Not necessarily. Cavities can grow silently without pain at first. Regular exams catch decay in these early, less painful stages, when treatment is simplest.
