Understanding that tooth cavities, also known as dental caries or tooth decay, are one of the most common dental problems worldwide, yet they’re also one of the most preventable, can empower you to take control of your oral health. When plaque, a sticky film of bacteria, interacts with sugars in food, it produces acid that wears down the enamel, leading to tooth cavities.
3 Types of Cavities
Not all cavities are the same. Depending on where and how they develop, dentists classify them into three main types. Knowing the difference can help you understand your condition better and choose the right tooth cavity treatment.
1. Smooth Surface Cavities
These cavities form on the flat, outer surfaces of your teeth, especially where teeth touch one another. They develop slowly and are often reversible in the early stages with fluoride treatments and good oral hygiene.
Common in:
- People who don’t floss regularly
- Areas between teeth (interdental cavities)
2. Pit and Fissure Cavities
These are the most common types of tooth cavities, especially in children and teenagers. They occur in the grooves (fissures) on the chewing surfaces of the back teeth (molars and premolars), where food particles often get stuck.
Common in:
- Molars with deep grooves
- Patients who skip sealants or proper brushing
3. Root Cavities
These occur on the root surfaces of teeth, often due to gum recession, exposing the root. Since roots don’t have protective enamel, these cavities can spread quickly and may require more extensive tooth cavity treatment like dental fillings or even root canals.
Common in:
- Older adults with receding gums
- People with dry mouth or gum disease
How Common are Cavities?
Cavities are extremely common, about 96% of Canadian adults have had at least one cavity, according to a national oral health survey (CHMS, 2007–09). Despite this high incidence, cavities are largely preventable through good oral hygiene and regular dental care.
5 Common Symptoms of Tooth Cavities
Tooth cavities can sometimes develop without obvious symptoms, which is why regular checkups are essential. However, common signs to look out for include:
- Toothache: A persistent or spontaneous pain without any clear cause.
- Sensitivity: Discomfort when consuming hot, cold, or sweet items.
- Visible Holes or Pits: Often visible on the chewing surfaces of molars.
- Staining: White, brown, or black spots on your tooth surface.
- Pain While Biting: Especially on specific teeth.
Being proactive and responsible for your oral health is crucial. If you notice any of these symptoms, it’s important to seek tooth cavity treatment immediately to avoid worsening decay.
5 Factors That Cause Tooth Cavities?
The development of tooth cavities is a gradual process and can be triggered by several factors:
1. Plaque Buildup
Plaque forms when bacteria feed on sugars and starches left on teeth, creating an acidic environment. This acid wears down the enamel, forming cavities.
2. Poor Oral Hygiene
Infrequent brushing and flossing allow plaque and food debris to remain, accelerating tooth decay.
3. Frequent Snacking or Sipping
Consuming sugary or acidic drinks regularly gives oral bacteria constant fuel to produce enamel-eroding acids.
4. Dry Mouth
Saliva helps wash away food particles and neutralize acids. A dry mouth can increase your risk of cavities.
5. Age and Genetics
Older adults often experience receding gums, exposing the root surfaces to decay. Genetics also play a role in cavity susceptibility.
5 Stages of Tooth Decay
Understanding the stages of tooth decay can help you act before it becomes serious:
- Demineralization: Early enamel weakening, often reversible.
- Enamel Decay: Small holes form in the surface enamel.
- Dentin Decay: Decay reaches the softer inner layer beneath the enamel.
- Pulp Damage: Infection or inflammation reaches the tooth’s nerve center.
- Abscess Formation: A painful pocket of pus develops, requiring urgent care.
Each stage requires specific tooth cavity treatment, which is why early detection is vital.
How to Treat Tooth Cavities
Treatments vary based on the severity of the cavity. Here’s a breakdown of the most effective dental treatments:
1. Fluoride Treatments
Effective in the very early stages, fluoride can remineralize enamel and stop decay in its tracks.
2. Dental Fillings
The most common tooth cavity treatment, where the decayed portion is removed and filled with composite, amalgam, or porcelain material.
3. Crowns
Used for extensive decay, a crown covers and protects a damaged tooth after decay removal.
4. Root Canals
Necessary when decay reaches the pulp. The infected tissue is removed, and the canal is sealed.
5. Tooth Extraction
In severe cases where the tooth cannot be saved, extraction followed by a dental implant or bridge may be recommended.
For tailored care, consult an experienced dentist in Woodbridge who can assess the right treatment for your condition.
6 Ways to Prevent Tooth Cavities
While cavities are common, they’re also entirely preventable with a few consistent habits:
- Brush Twice a Day: Use fluoride toothpaste and brush for two minutes.
- Floss Daily: Removes plaque from between teeth where brushes can’t reach.
- Limit Sugary Foods and Drinks: Opt for tooth-friendly snacks like cheese, vegetables, and nuts. Also, a balanced diet with adequate calcium and vitamin D can help strengthen your teeth and prevent cavities.
- Use Mouthwash: Especially those containing fluoride for added protection.
- dentalRegular Dental Visits: Biannual visits, especially to a dentist in Woodbridge, can help catch issues early, providing you with reassurance and confidence in your oral health.
- Get Dental Sealants: Especially for children and teenagers to protect molars from decay.
Your commitment to oral hygiene directly affects your cavity risk and long-term tooth decay prevention.
The Cost of Ignoring Cavities
According to a 2025 report by the Canadian Dental Association, nearly 1 in 3 Canadian adults has untreated cavities, often due to delayed checkups or poor awareness. The same report also found that over 40% of dental emergencies in Canada stem from untreated tooth decay an issue entirely preventable with early intervention.
Delaying tooth cavity treatment can lead to:
- Increased pain and discomfort
- Risk of infection and tooth loss
- Costlier procedures like root canals or crowns
- Impact on overall health, including cardiovascular issues
This makes untreated cavities the leading cause of emergency dental visits in Canada a trend that’s entirely preventable with routine checkups and timely care.
Children and Tooth Cavities: What Parents Should Know
Children are highly susceptible to tooth cavities, especially in molars. Here are a few things parents can do:
- Encourage brushing with fluoride toothpaste from an early age
- Avoid putting babies to bed with bottles
- Schedule pediatric dental visits by age one
- Teach healthy snack habits
- Consider sealants around age 6–7
The earlier we teach dental care habits, the less likely our children will suffer from tooth decay in adulthood.

FAQs About Tooth Cavities
1. Can cavities heal on their own without treatment?
Cavities do not heal on their own once a hole has formed in the enamel. However, very early enamel damage (demineralization) can sometimes be reversed with fluoride treatments, good brushing habits, and dietary changes.
2. Is every toothache a sign of a cavity?
Not necessarily. Toothaches can also be caused by gum issues, teeth grinding, or infections. But a persistent ache is one of the primary signs of tooth cavities, so it’s important to consult a dentist for a proper diagnosis.
3. How long does it take to develop a cavity?
Cavity formation depends on oral hygiene, diet, and genetics. Some cavities develop over months, while others may take years. Regular dental exams can catch tooth decay early before it becomes serious.
4. What is the most effective tooth cavity treatment?
Fillings are the most common and effective way to treat cavities once they’ve formed. The dentist removes the decay and fills the space with a safe material. In more advanced cases, crowns or root canals may be needed.
5. Is it normal for kids to get cavities even with brushing?
Yes, children are still at risk due to their thinner enamel, eating habits, and difficulty brushing effectively. That’s why parental supervision, fluoride toothpaste, regular dental visits, and sometimes sealants are essential for preventing tooth cavities.
