Cavities in Markham, ON

Cavities are caused by tooth decay gradually developing over time. This begins with bacteria feeding on teeth when sugars and starches are not effectively cleaned away. Plaque then forms coats teeth as a clear sticky film and eventually hardens above or below the gum line into tartar, making it more difficult to remove.

Plaque acids ultimately erode enamel until they reach the dentin, closer to the nerve and can cause sensitivity. Bacteria and acid move through the pulp, causing irritation, swelling, and pain—possibly even reaching the bone.

Signs And Symptoms

Possible Complications

Pain
Tooth abscess
Swelling or pus around teeth
Damaged or broken teeth
Chewing problems affecting nutrition
Tooth loss
Misalignment

Risk Factors

Molars and premolars
These teeth are more susceptible to cavities because they have grooves, pits, and multiple roots that can collect food particles and are harder to clean
Certain foods and drinks
Sugary, hard, dry, chewy, and dairy foods that saliva cannot easily wash away means they ultimately remain on teeth for more prolonged periods
Frequent snacking
Snack foods and sugary drinks without breaks for saliva and water to wash them away can cause acid to attack your teeth and wear down the enamel
Bedtime feedings
Milk, formula, or juice before bed remain on teeth while we sleep—no matter our age, we should not eat or drink anything before bed besides water
Inadequate brushing
Plaque forms quickly if you do not effectively clean teeth, which will lead to the initial stages of tooth decay
Dry mouth
Certain medications, medical conditions, radiation, or chemotherapy drugs can reduce saliva production, which may cause tooth decay when food, plaque, and acid are not being washed away
Weakening dental fillings or appliances
Plaque and decay can form more quickly by getting under fillings or appliances if the former is worn down and the latter are ill-fitting
Heartburn
Heartburn and acid reflux bring stomach acid up to your mouth, which can wear away enamel and cause tooth damage and decay
Eating disorders
Anorexia and bulimia may impact the production of saliva, erode enamel, and cause cavities due to stomach acid entering the mouth as a result of vomiting

Practicing good oral hygiene will help deter them, but other factors (including even possible genetic inheritance) can cause tiny holes in your teeth to develop.

Frequently Asked Questions About Cavities In Markham

What causes cavities in teeth?

Cavities are caused by a buildup of bacteria and plaque on teeth. When sugars and starches are not cleaned away properly, acids are produced that erode tooth enamel and eventually cause decay.

What are the early signs of a cavity?

Early signs include tooth sensitivity, mild pain when eating or drinking, white or dark spots on teeth, and small holes or pits. In later stages, pain becomes stronger and may affect chewing.

Can cavities heal on their own?

Once a cavity forms, it cannot fully heal on its own. However, in the very early stages (when enamel is just starting to weaken), fluoride treatments, good oral hygiene, and dental checkups may help stop or reverse decay before it worsens.

How are cavities treated at the dentist?

Dentists usually treat cavities with dental fillings, where the decayed portion is removed and replaced with composite resin or another durable material. In more advanced cases, root canals or crowns may be needed.

What happens if I don’t treat a cavity?

An untreated cavity can grow larger, causing severe pain, tooth abscesses, infections, and even tooth loss. It can also affect chewing, nutrition, and overall oral health.

How can I prevent cavities from forming?

You can prevent cavities by brushing twice daily with fluoride toothpaste, flossing regularly, limiting sugary foods and drinks, drinking fluoridated water, and visiting your dentist for checkups and cleanings. Dental sealants and fluoride treatments are also effective preventive measures.

Are cavities common in adults or just children?

Cavities are common in both children and adults. Risk factors like dry mouth, frequent snacking, worn fillings, and acid reflux can increase the likelihood of developing cavities at any age.
