Cavities—also known as tooth decay—are one of the most common dental problems affecting children, teens, and adults alike. While cavities are widespread, they’re also largely preventable with proper oral care and regular dental visits. At Dr. Jason Augustine DDS, we focus on early detection, advanced treatment, and long-term prevention to help patients throughout Phoenix maintain healthy, confident smiles.
This guide explains everything you need to know about cavities, from early warning signs to treatment options and prevention strategies.
What Is a Cavity?
A cavity is a permanently damaged area in the hard surface of a tooth that develops into a tiny hole or opening. Cavities occur when plaque bacteria produce acids that erode tooth enamel over time. If left untreated, cavities can progress deeper into the tooth, causing pain, infection, and even tooth loss.
Types of Cavities
Cavities can form in different areas of the tooth, depending on oral habits and anatomy:
- Smooth surface cavities—Develop on the flat surfaces of teeth
- Pit and fissure cavities—Common on the chewing surfaces of molars
- Root cavities—Occur on exposed tooth roots, often linked to gum recession
- Recurrent cavities—Form around existing fillings or crowns
Each type requires a customized treatment approach, which Dr. Augustine carefully evaluates during your exam.
How Common Are Cavities?
Cavities are extremely common. According to dental health data, most adults will experience at least one cavity during their lifetime. Children and teens are especially vulnerable, but adults—particularly those with dry mouth, gum disease, or previous dental work—remain at risk.
Who Might Get a Cavity?
Anyone can develop cavities, but the risk is higher for people who:
- Frequently consume sugary or acidic foods and drinks
- Have poor oral hygiene habits
- Experience dry mouth
- Have gum recession or exposed roots
- Skip regular dental checkups
- Wear braces or dental appliances
Symptoms and Causes
What Are the Signs of Cavities?
Cavity symptoms vary depending on severity and stage. Common signs include:
- Tooth sensitivity to hot, cold, or sweet foods
- Toothache or spontaneous pain
- Visible holes or dark spots on teeth
- Pain when biting or chewing
- Bad breath or unpleasant taste
Early cavities may cause no symptoms at all, which is why routine dental exams are critical.
Tooth Decay Stages
Tooth decay develops gradually in stages:
- Demineralization—Acid attacks weaken enamel
- Enamel decay—small cavities begin to form
- Dentin decay—Decay spreads beneath enamel, increasing sensitivity
- Pulp damage—Infection reaches the nerve, causing pain
- Abscess—Severe infection that may threaten overall health
Early treatment can stop decay before it reaches advanced stages.
What Causes Cavities?
Cavities form due to a combination of factors:
- Plaque buildup on teeth
- Frequent sugar and carbohydrate consumption
- Acid production by bacteria
- Inadequate brushing and flossing
- Insufficient fluoride exposure
Over time, repeated acid attacks weaken enamel and lead to decay.
What Are the Risk Factors for Cavities?
Key cavity risk factors include:
- Sugary snacks and drinks
- Poor oral hygiene
- Dry mouth (xerostomia)
- Acid reflux
- Worn or damaged dental restorations
- Lack of professional cleanings
Dr. Augustine helps patients identify and reduce these risk factors through preventive dentistry.
Are Cavities Contagious?
Cavities themselves are not contagious, but the bacteria that cause them can be passed through saliva, especially between parents and young children. Maintaining good oral hygiene and avoiding saliva sharing helps reduce bacterial transmission.
Diagnosis and Tests
How Are Cavities Diagnosed?
At Dr. Jason Augustine DDS, cavities are diagnosed using:
- Comprehensive oral exams
- Digital dental X-rays
- Visual and tactile inspection
- Advanced diagnostic tools
Early detection allows for simpler, less invasive treatment.
Management and Treatment
How Do You Get Rid of Cavities?
Treatment depends on how advanced the cavity is.
Fluoride Treatment
Early-stage cavities may be reversed with professional fluoride treatments that strengthen enamel and stop decay progression.
Dental Fillings
When decay has created a hole in the tooth, dental fillings restore structure and function. Tooth-colored composite fillings are commonly used for natural-looking results.
Root Canal Therapy
If decay reaches the pulp, root canal therapy removes infected tissue, relieves pain, and saves the natural tooth.
Tooth Extraction
In severe cases where the tooth cannot be saved, extraction may be necessary. Dr. Augustine also discusses replacement options to restore your smile.
Outlook / Prognosis
What Can I Expect If I Have Cavities?
With early treatment, cavities are highly manageable. Most patients experience quick relief and excellent long-term outcomes when decay is addressed promptly.
What’s the Outlook for People With Cavities?
The outlook is very positive with proper care. Ongoing preventive dentistry and good home hygiene can prevent future cavities and protect your oral health for years to come.
Prevention
How Can I Prevent Cavities?
Cavity prevention starts with daily habits and professional care:
- Brush twice daily with fluoride toothpaste
- Floss once a day
- Limit sugary foods and beverages
- Drink plenty of water
- Schedule regular dental cleanings
- Use fluoride treatments when recommended
Preventive dentistry is the foundation of long-term oral health.
Living With Cavities

Contact your periodontist if you notice:
- Tooth pain or sensitivity
- Visible spots or holes in teeth
- Swelling or signs of infection
- Pain when chewing
Early intervention prevents complications.

FAQs
1. What exactly is a cavity?
A cavity is a damaged area in a tooth where decay has caused a small hole or opening. It forms when acids produced by bacteria wear down tooth enamel over time.
2. How do acids in the mouth cause cavities?
When you eat sugary or starchy foods, bacteria in your mouth feed on them and produce acids. These acids attack tooth enamel, weakening it and eventually creating cavities.
3. Can cavities form without pain?
Yes. Early cavities often cause no pain or symptoms. This is why regular dental exams with Dr. Jason Augustine, DDS, are essential for catching decay early.
4. Can a cavity heal once enamel is damaged?
No. Once enamel is permanently damaged, a cavity cannot heal on its own. Early mineral loss may be reversed, but formed cavities require professional treatment.
5. How can I prevent cavities from forming?
You can reduce your risk by brushing twice daily with fluoride toothpaste, flossing daily, limiting sugary foods and drinks, and scheduling regular dental checkups in Phoenix, AZ.
