A dental cavity is a permanent hole in your tooth caused by decay, and it occurs when harmful bacteria weaken enamel over time. Understanding what is dental cavity, and how to prevent it, is one of the most effective ways to protect your oral health for life. Cavities are extremely common, but with the right habits and the guidance of a skilled dentist in Brampton, prevention is absolutely possible.
Healthy teeth allow you to chew comfortably, speak clearly, and smile confidently. At Mayfield Dental Clinic, we specialize in dental cavity prevention for families and professionals across Mayfield West, Heart Lake, Bramalea, and Castlemore. In this blog, we break down how cavities form, warning signs, prevention strategies, and what to expect if you need a cavity filling in Brampton.

- Prevention includes brushing twice daily, flossing, fluoride use, and limiting sugary snacks.
- Regular checkups with a skilled dentist help detect and treat cavities early.
- If needed, a cavity filling in Brampton restores the tooth and prevents further damage.
What Is a Dental Cavity?
Anatomy of a Tooth: Enamel, Dentin & Pulp
Before understanding decay, it helps to understand the tooth’s layers.
Key points about tooth structure:
- Enamel is the strongest substance in the body and your tooth’s first line of defense.
- Dentin, beneath enamel, is softer and more vulnerable; once decay reaches it, damage accelerates.
- Pulp contains nerves and blood vessels; if decay reaches this layer, pain or infection can occur.
Keeping enamel strong is the foundation of cavity prevention.
How Cavities Form — From Plaque to Decay
Cavities build slowly through repeated acid exposure.
Here’s how the decay process works:
- Bacteria in the mouth feed on sugars and starches, producing acid.
- Acid attacks enamel, causing mineral loss, often seen as white chalky spots.
- Without intervention, the enamel breaks down, and a cavity forms.
- The cavity deepens into dentin, eventually reaching the pulp if left untreated.
“A cavity rarely starts as a big problem; it starts as a tiny moment of neglect,” explains Dr. Nibal Kellow Pasat. “Small, consistent habits are what protect your smile long-term.”
Why Cavities Matter — Risks & Consequences
Symptoms & When You Might Notice a Cavity
Not all cavities hurt; many are silent until advanced.
Common signs include:
- Sensitivity to sweet, hot, or cold foods
- Discomfort when chewing
- Visible pits or dark spots
- Persistent bad breath
- Rough or sharp areas on the tooth
Adults may also develop root cavities, especially with gum recession.
What Happens If You Ignore a Cavity
Unchecked decay can progress quickly.
Possible consequences:
- Infection or abscess
- Pain requiring emergency care
- Root canal treatment
- Tooth loss
- Spread of bacteria impacting overall health

How to Prevent a Dental Cavity (Practical, Everyday Tips)

Your daily prevention checklist:
- Brush twice daily using fluoride toothpaste
- Brush for a full two minutes
- Use gentle circular motions near the gumline
- Floss once a day to remove plaque between teeth
- Rinse with an antibacterial mouthwash if recommended by your dentist
- Replace your toothbrush every 3–4 months

Diet & Lifestyle Habits That Protect Teeth
Your eating habits play a major role in cavity development.
Here’s how to strengthen your prevention lifestyle:
- Reduce frequent snacking, especially sugary or sticky foods
- Choose water over soda, juice, or sports drinks
- Eat crunchy vegetables and fruits to stimulate saliva
- Limit acidic beverages like sparkling water and citrus drinks
- Avoid grazing, as each eating session creates a new acid attack cycle
Remember: it’s not just what you eat; it’s how often you eat it.
Role of Fluoride, Saliva & Regular Dental Visits
Your body and dental team work together to strengthen and protect teeth.
Important cavity-fighting supports include:
- Fluoride, which remineralizes enamel and reverses early decay
- Saliva, which neutralizes acids and protects enamel
- Regular checkups, which allow early detection and prevention
An expert dentist in Brampton can identify weak enamel areas, monitor cavity-prone teeth, and recommend personalized strategies, especially if your cavity risk is higher than average.
“Preventive dentistry isn’t about drilling, it’s about preserving what’s healthy,” says Dr. Nibal Kellow Pasat. “Our goal is to keep the natural tooth strong for as long as possible.”

When Cavities Occur — Modern Treatment Options
Dental Fillings & What to Expect (Cavity Filling Brampton)
When a cavity forms, a filling restores your tooth’s integrity.

- Local numbing for comfort
- Gentle removal of decayed tooth structure
- Placement of a custom filling (usually white composite)

- Polishing for a natural look
Cavity filling services in Brampton prioritize comfort and natural aesthetics.
Minimally Invasive Approaches & Reinforcement Techniques
For early cavities or tiny enamel defects, your dentist may recommend:
- Remineralization treatments
- Fluoride varnishes
- Sealants on deep grooves
- Resin infiltration techniques
These treatments preserve more natural tooth structure.
Suspect a cavity? Don’t wait. Early, small fillings are faster, more comfortable, and more affordable than delayed treatment.
