Cavities And Dental Decay Care Near You

Tooth decay can start quietly, but it may progress into sensitivity, pain, and infections when left untreated. Cavities form when bacteria interact with sugars and starches, creating acids that wear down enamel over time. Even patients who brush regularly can develop decay in hard-to-reach areas, along the gumline, or between teeth.

At Alora Dental in Toronto, we help patients understand why cavities happen, how to spot early warning signs, and which treatment options can restore tooth structure while supporting long-term oral health. With routine dental exams and professional cleanings, many concerns can be found early, when care is simpler and more conservative.

Cavities develop when enamel is repeatedly exposed to acid created by bacteria in plaque. Over time, enamel weakens and teeth may become sensitive, rough, or more likely to trap food. Understanding the most common contributors can help patients reduce risk and protect their smiles.

Bacteria And Plaque

The mouth naturally contains bacteria that attach to teeth in a sticky film called plaque. If plaque is not removed consistently, bacteria feed on sugars and release acids that gradually break down enamel, increasing the risk of dental caries.

Sugary and Acidic Diets

Frequent snacking, sweetened drinks, soda, sports drinks, flavored coffee, and acidic beverages can increase cavity risk by providing a steady supply of sugar and acid. Even naturally occurring sugars in juice and fruit can contribute to decay when brushing and flossing are inconsistent.

Poor Oral Hygiene Habits

When brushing and flossing are not thorough or not done often enough, plaque can build up and harden into calculus. Calculus makes home care more difficult and increases the likelihood of tooth decay and gum inflammation.

Dry Mouth

Saliva helps neutralize acids and rinse away food particles and bacteria. Reduced saliva flow, often related to medications, mouth breathing, certain health conditions, or medical treatments, can leave teeth more vulnerable to decay.

Cavities can look and feel different from one patient to another. Some areas of decay develop slowly with little discomfort, while others progress more quickly, especially between teeth or under older fillings. Recognizing early changes allows patients to seek care before problems become more advanced.

Common symptoms may include:

• Toothache or pain that comes and goes
• Sensitivity to hot, cold, or sweet foods and drinks
• Visible pits, holes, or rough areas on a tooth
• White, brown, or dark discoloration on enamel
• Discomfort or pressure when biting or chewing
• Persistent bad breath or an unpleasant taste
• Swelling, tenderness, or drainage near a tooth in advanced cases

If you notice one or more of these symptoms, booking an assessment promptly helps our team evaluate the tooth and discuss next steps before decay spreads deeper.

Treatment recommendations depend on how much tooth structure is affected and the overall condition of the tooth. Our focus is to remove decay, preserve as much natural tooth as possible, restore function, and reduce the risk of future cavities.

Dental Fillings

For mild to moderate cavities, the decayed portion of the tooth is removed and restored with a filling. Tooth-colored composite fillings are commonly used to blend naturally with surrounding enamel while restoring strength and comfort.

Dental Crowns

When decay is extensive or a tooth has weakened significantly, a crown may be recommended. A crown covers and protects the tooth after decay is removed, helping restore durability and appearance.

Root Canal Therapy

If decay reaches the pulp, infection and significant discomfort may occur. Root canal therapy removes infected tissue, cleans the inside of the tooth, and seals it. A crown is typically placed afterward to protect the tooth from fracture.

Tooth Extraction

When a tooth cannot be saved due to advanced decay, extraction may be recommended to protect nearby teeth and gums. If appropriate, we can discuss replacement options such as dental implants or dental bridges.
