What Is Exposed Dentin?

Exposed dentin occurs when the protective enamel or gums wear away, leaving the inner layer of your tooth vulnerable. Dentin is normally covered and shielded, but once exposed, it can lead to tooth sensitivity, pain, and higher risk of decay. At Aegis Dental Centre, we often see patients experiencing discomfort from exposed dentin, and we provide effective treatments to restore comfort and protect long-term oral health.

Causes of Exposed Dentin

There are several common reasons patients develop exposed dentin:

• Enamel erosion: Acidic foods, sugary drinks, or acid reflux wear down enamel.
• Tooth decay: Cavities progress until they reach the dentin layer.
• Gum recession: Often linked to gum disease or aggressive brushing, exposing tooth roots.
• Bruxism (teeth grinding): Constant grinding thins enamel and uncovers dentin.
• Trauma or injury: Cracks or chips expose deeper layers.

Identifying the causes of exposed dentin early allows for faster, more effective treatment.

Symptoms of Exposed Dentin

Patients with exposed dentin often report:

• Sharp tooth sensitivity to hot, cold, sweet, or acidic foods
• Pain while brushing, flossing, or chewing
• Yellowish or darker areas on teeth where enamel has worn away
• Rough or uneven tooth surfaces

If you notice these symptoms of exposed dentin, don’t wait. Early diagnosis at Aegis Dental Centre can prevent worsening damage.

Why Exposed Dentin Matters

Leaving exposed dentin untreated increases your risk of:

• Dentin hypersensitivity: Persistent discomfort that affects eating and drinking.
• Cavities and decay: Without enamel, dentin is more prone to bacterial attack.
• Cracks and fractures: Teeth become weaker and more vulnerable to breakage.
• Infection risk: If bacteria reach the pulp, root canal treatment may be needed.

Exposed dentin is more than just a sensitivity issue—it’s a warning sign of potential long-term dental problems.

Treatment Options for Exposed Dentin

The right treatment for exposed dentin depends on its severity and cause:

1. Desensitizing toothpaste – blocks pain signals for mild sensitivity.
2. Fluoride treatments – strengthen enamel and reduce discomfort.
3. Dental bonding or sealants – protect the dentin surface with a tooth-colored material.
4. Crowns or veneers – cover and strengthen teeth with advanced enamel loss.
5. Gum grafting – addresses dentin exposure caused by gum recession.

At Aegis Dental Centre, we tailor solutions to your unique needs to restore both comfort and function.

Preventing Exposed Dentin

Prevention is the best long-term solution. Reduce your risk of exposed dentin by:

• Brushing gently with a soft-bristled toothbrush
• Using fluoride toothpaste daily
• Wearing a night guard if you grind your teeth
• Avoiding acidic foods and sugary beverages
• Scheduling routine cleanings and checkups

Protecting your enamel and gums today lowers the chance of dentin exposure tomorrow.
