Frequent acid exposure can dissolve tooth structure. Management addresses the acid source as well as damage to the teeth.

Tooth health

Congenitally Missing Teeth: Diagnosis and Options

When an adult tooth never develops, planning considers growth, space, the bite and the health of any retained baby tooth.

Restorative care

Cracked Fillings: Signs, Risks and Treatment

A damaged filling may expose the tooth to further wear or decay. Assessment helps determine whether repair or replacement is needed.

Tooth health

Cracked Teeth: Symptoms and Treatment Options

Cracks vary in depth and severity. Early assessment can help identify options for protecting or treating the tooth.

Restorative care

Dental Build-Ups: Rebuilding a Damaged Tooth

A build-up replaces missing tooth structure so a tooth can support its planned restoration.

Restorative care

Dental Crowns: Benefits, Risks and Alternatives

A crown covers and restores a tooth, but does not remove the need for ongoing cleaning and decay prevention.

Restorative care

Dental Inlays and Onlays: When Are They Used?

Inlays and onlays replace missing tooth structure and may provide a middle ground between a filling and a full crown.

Restorative care

Dental Post and Core: Purpose, Risks and Alternatives

A post may help retain a core when little tooth structure remains after root canal treatment; not every treated tooth needs one.

Restorative care

Discoloured Fillings: Staining or Something More?

A dark filling may be stained or may need closer assessment for an open edge or decay. Colour alone does not decide treatment.

Tooth health

Discoloured Teeth: Causes and Treatment Options

A tooth that changes colour may have surface stain, an old restoration, previous trauma or a problem inside the tooth.

Tooth health

External Root Resorption: Diagnosis and Treatment

Root resorption may progress without pain. Imaging and the location of damage guide monitoring or treatment.

Tooth health

Restorative care

Tooth-Supported Dental Bridges

A bridge uses supporting natural teeth to replace a missing tooth or teeth. Preparation, cleaning and support-tooth health matter.

A tooth with substantial missing structure may need additional support to reduce the risk of fracture.

Gums, Bone and Mouth Tissues

Understand gum disease, grafting, tissue changes and when a mouth sore or swelling needs assessment.

Surgical care

Crown Lengthening: Why It May Be Recommended

Crown lengthening changes the gum line and sometimes the supporting bone to expose more tooth for restoration or appearance.

Surgical care

Dental Bone Grafting: Benefits, Risks and Recovery
