Treating Notches at the Gumline: Cervical Lesion Repair, A Case Study

If a tooth has started to look slightly notched right where it meets the gum — or feels sensitive in that spot — there may be a cervical lesion. These small areas of damage near the gumline are common, and they are worth treating before they cause bigger problems.

This case study from SOL Dental Arts in Maspeth, Queens shows how cervical lesions were treated with tooth-colored restorations — protecting the teeth, improving comfort, and restoring a healthier contour at the gumline.

What is a cervical lesion?

A cervical lesion is an area of damaged tooth structure near the gumline — the cervical region of the tooth. It can be caused by abfraction (stress on the tooth), erosion, wear, or decay. Cervical lesions tend to make a tooth look notched, can feel sensitive, and leave that part of the tooth more vulnerable over time if it is not addressed. Because they sit at the gumline, treating them is often both a functional and an esthetic matter.

The case: protecting teeth at the gumline

This patient had cervical lesions — notched, damaged areas near the gumline that were affecting both comfort and the appearance of the teeth.

The team used tooth-colored restorative treatment to address them. The goal was twofold: seal and protect the vulnerable area of each tooth, and do it with a restoration that blends naturally with the surrounding enamel — restoring a smooth, healthier contour at the cervical margin.

How cervical lesions are treated

A cervical lesion case at SOL Dental Arts follows a careful sequence:

• Evaluation of the cervical wear, erosion, or decay — identifying the cause and extent of the damage.

• Tooth-colored restorative treatment — placing a restoration that matches the natural tooth.

• Sealing and contour repair near the gumline — protecting the area and rebuilding a smooth shape.

• Finishing for comfort and esthetics — refining the restoration so it feels and looks natural.

Tooth-colored restorations are designed to blend in while protecting the tooth, so the treatment improves both comfort and appearance.

Why treat a cervical lesion?

Cervical lesions do not improve on their own, and the affected area can become more sensitive and structurally weaker over time. The damaged surface can expose dentin and compromise the tooth's natural protective layer. Treating the lesion seals and protects the tooth, restores its form, and often reduces sensitivity. An evaluation is the best way to know whether a bonded restoration is the right step.

The result

By restoring the cervical lesions with tooth-colored material, this case protected the teeth and restored a smoother, healthier gumline contour. A well-planned cervical lesion treatment should:

• Help reduce sensitivity

• Protect vulnerable tooth structure

• Restore a smooth contour at the gumline

• Deliver a tooth-colored, natural-looking result

Frequently asked questions

What is a cervical lesion?

A cervical lesion is a defect near the gumline that may be caused by wear, stress (abfraction), erosion, or decay. It can leave the tooth looking notched and feeling sensitive.

Why are these areas so sensitive?

Because the damaged area can expose dentin — the layer beneath the enamel — and compromise the natural protective surface of the tooth, which can make it sensitive.

Can the repair match the tooth?

Yes. Tooth-colored restorations are designed to blend in with the natural tooth while sealing and protecting the area.

Will treatment help with the sensitivity?

Often, yes. Sealing and restoring the lesion protects the exposed area, which commonly helps reduce sensitivity — though results vary by case.
